DIGESTIVE SYSTEM
All living organism require food for energy and organic matters for growth . food is organic compound and usually of plant or animal origin . The major components of our food are carbohydrates , proteins and fats . The process of conversion of complex food substances to simple absorbable term is called digestion and is carried out by our digestive system by mechanical and biochemical methods . The organs of the gastrointestinal tract includes the mouth , pharynx , esophagus ,
stomach , small intestine , large intestine .

a)            Mouth :
The mouth is formed by cheeks , palates , lips and tongue .
Teeth :
Teeth cut , tear and pulnerize food to reduce solids to smaller particles for swallowing . majority of mammals have two sets of teeth . an adult human has 32 permanent teeth which is of 4 types namely incisors , canine , premolars , and molars .

 Tongue :
Movement of tongue are important in guiding food within the mouth during chewing and swallowing . further more the taste buds are located on the tongue .


B ) PHARYNX :

When food is first swallowed , it passes from mouth into the pharynx , a funnel shaped tube that extends from the internal nares to the esophagus posteriorly . It acts as a common passage way for both the digestive system and the respiratory system .



C ) ESOPHAGUS :

The esophagus connects the pharynx to the stomach . It is a muscular tube approximately 25 cm long . In the esophagus , the submucosa contains mucus secreting submucosal esophageal gland . both submucosal and mucosal gland secrete mucus for lubrication of esophageal epithelial linning . The esophagus plays an important role in the chemical digestion of food .

D ) DIAPHRAGM :

The diaphragm is an important part of the body digestive  system . The muscular diaphragm separates the thoracic cavity from the abdominal cavity where most of the digestive organs are located . This muscle helps in flexure for the easy passage of digesting material .

E ) STOMACH :

The stomach is a major organ of the digestive system . It is a j shaped organ joined to the esophagus at its upper end and to the duodenum at its lower end . gastric acid produced in the stomach plays an important role in digestion . It mainly composed of hydrochloric acid and sodium chloride . The stomach of a new born baby will only be able to expand to retain about 30ml .
F ) SPLEEN :

The spleen breaks down both red and white blood cells. A product of digestion is the pigment bilirubin which is sent to the liver and secreted in the bile .

G ) LIVER :

The liver is the second largest organ and is an accessory digestive gland which plays a role in the body metabolism . the liver can detoxify various metabolites , synthesis protein , and produce biochemical needed for digestion . The liver also can synthesis glucose .

H ) GALL BLADDER :

The gall bladder is a hollow part of the biliary tract that sits just beneath the liver , with the gallbladder body resting in a small depression . It is divided into fundu , body and neck .


I ) PANCREAS :

The pancreas is a major part of digestive organ which has both endocrine and exocrine gland . The endocrine gland secretes insulin when blood glucose is high . The endocrine part releases glucagon when blood sugar is low . The pancreas is also the main source of enzymes for digestion of fats and proteins .


J ) SMALL INTESTINE :

Food starts to arrive in the small intestine one hour after it is eaten , and after two hours the stomach has emptied . In the small intestine , the pH becomes crucial , it needs to be finely balanced in order to activate digestive enzymes . when the digested food particles are reduced enough in size and composition , they can be absorbed by intestinal wall and carried to the bloodstream . 
The last part of the small intestine is the ileum . This also contains villi and vitamin b12 , bile acids , and any residue nutrients are absorbed here .

K ) LARGE INTESTINE :

It takes about 12 to 50 hours until it is removed by defecation . The colon mainly serves as a site for the fragmentation of digestible matter by the gut flora . The remaining  semi solid waste is termed feces and is removed by the coordinated contractions of the intestinal walls , termed peristalsis , which propels the excreta forward to reach the rectum and exit via defecation from the anus .


The 6 major functions take place in the digestive system  they are ,
·       Ingestion
·       Secretion
·       Mixing and movement
·       Digestion
·       Absorption
·       Excretion

DIGESTIVE DISORDER :
Many diseases and health conditions such as ulcers , GERD , IBD  and celiac disease .

HOW TO USE COMPUTER

How to use computer

Set up your computer
. If you are setting up a new desktop computer, there are a few steps you will need to go through before you can start using it. After finding a place near your desk to put the tower, you will need to connect your monitor, keyboard, and mouse, as well as plug the tower into a power source.
·         These are the only things required to be connected to the computer in order to use it. You can add more peripherals and accessories later.
·         If you are using a new laptop, you will have significantly less to set up. Plug your laptop into a power source to ensure that it is charged, and then power it on to begin.

Create a user account.
 If you are using the computer for the first time, you will likely be asked to create a user account when you turn it on. This account will hold all of your documents, pictures, downloaded files, and any other files that you create.
·         If your computer is in a public setting, you should create a strong password to protect your personal information. This is highly recommended, even if your computer is a home computer.

Get familiar with the desktop. The desktop is the main work area of your computer, and will likely be the most visited area of your computer. Your desktop appears every time you log into your account, and contains icons and shortcuts to your most used programs and files. The desktop will look and function differently depending on which operating system you use.

Learn mouse and keyboard basics.
 The mouse and keyboard are your primary means of interacting with your computer. Take some time to get familiar with how they work and how you can interact with your operating system and programs.

Launch some preinstalled applications.
 Even if you built your computer yourself, there will be some preinstalled applications and utilities that you can use without having to install anything additional. If you are using Windows, click the Start menu and browse through your available programs. If you are using a Mac, check your Dock and Applications folder.

Install your first program.
 Installing software is a very common task on a computer, no matter what kind of computer you are using. The process is usually very straightforward, as most installers give clear instructions for each step.

Select files and text.
 You can use your mouse or keyboard shortcuts to select files on your computer and text on documents and website. Click and drag the mouse across the text you want to select, or press Ctrl+A to select everything in your current location. Once you've selected files or text, there are several different actions you can take.

Copy and paste
. Copying and pasting is one of the most common actions taken when selecting text or files. "Copying" a file or text leaves the original intact, while creating a copy on your computer's clipboard. You can then "Paste" the file or text elsewhere.
·         For PC, copy by pressing Ctrl+C and paste by pressing Ctrl+V. You can also copy and paste by right-clicking on the selection with your mouse and selecting the appropriate option from the menu.

·         .Save and open files. Many programs such as word processors, photo editors, and more allow you to create and save documents and files. When working on a computer, it is wise to save often. You never know when the power might go out, costing you hours of unsaved work. Get in the habit of saving often, and if you are making major revisions to a file it might be wise to create a new copy. You can quickly save your work in most programs that allow saving by pressing Ctrl+S 



Set up a connection.
 In order to connect to the internet, your computer will need to have access to an internet connection. This may come in the form of a wireless network, or you may need to connect your computer directly to your network's router or modem. All of this depends on how the network at your location is configured, and the capabilities of your computer.

Open a web browser.
 The web browser is the software that allows you to view webpages, watch online videos, download files, and do essentially everything else internet-related. All computers come with a browser installed by default (Internet Explorer on Windows, Safari on Mac, and Firefox on Linux), but there are several popular alternative options.

Install an antivirus
. Before exploring the internet, it would be wise to install an antivirus program. These programs protect your computer from viruses and other malicious software, and are practically required when connecting to the internet. Most computers come with trial antivirus software installed, but there are plenty of powerful free alternatives.


Browse safely when online
. There is a lot of bad stuff on the internet, so be sure to stay safe while browsing. This means avoiding giving out personal information, only downloading from trusted sources, and steering clear of viruses, scams, and other illegal and dangerous activity.

Send an email
. Emailing is one of the most common forms of communication these days, and knowing how to send an email is now an essential computer skill. You can set up a free email account with a variety of different services, and can be composing an email in just a few minutes.

Add speakers
. While virtually all laptop computers have speakers built-in, desktop computers generally need external speakers or headphones in order for you to hear sound. Most computers have speaker connectors built-in that can be accessed on the back of the tower. Computer speakers are generally color-coded, so simply match the colored speaker plugs to the correct port.

Learn basic troubleshooting tips
. Like anything electronic, your computer will occasionally encounter problems. Knowing some basic troubleshooting tips can help save you a lot of time and potentially money. You don't have to be an expert, but knowing what to try first can be very beneficial.
·         The first thing you should try whenever you are encountering a problem is resetting your computer. Believe it or not, this will resolve a large number of issues you are having with a program or function.
·         If you are having connectivity problems when browsing the internet, resetting your connection may fix your problem.

How to use keyboard in computer :

Step 1: Have a good look at your keyboard. The most important keys are labelled on the diagram below:



Step 2: The main keys are the letter keys. When you type just using these, you get lower-case print. However, if you hold down a ‘shift key’ (there are two to choose from) at the same time as you type, you’ll get UPPER-CASE letters.

Try typing your name, including capitals (UPPER-CASE) and spaces. The ‘space bar’ (which you press briefly to make a space) is the wide key at the bottom of the keyboard.


Step 3: If you make a mistake in your typing, there’s always a remedy.

To delete a letter, place your cursor (mouse pointer) just after the letter and click. Then press Backspace briefly. (Always press briefly – otherwise, you’ll get repeated deletions, spaces, letters or whatever.) Or place your cursor just before the letter, click and press Delete.

Step 4: Now try typing a sentence:



This is a good sentence to practise because it contains most of the letters of the alphabet.
 Step 5: You can move the cursor along this sentence without deleting anything by using the arrow keys:


Try moving the cursor backwards and forwards through your sentence.

 Step 6: Now try using the number pad, if you have one.

To use this to type numbers, you have to press the Num Lock key. There may be an indicator light at the top of the keyboard or on the ‘Num Lock’ key itself to show that it’s on.


Step 7: You can also type using the numbers on the main keyboard. You’ll find them on the row of keys above the top line of letters.

Above these numbers are various symbols, which include ‘£’, ‘&’, ‘!’. To use these, hold down the Shift key while you type.

Step 8: If you want everything to appear in upper case, press the Caps Lock key and then type.

Again, an indicator light may come on to show that your capitals are ‘locked’. Don’t forget to press this key again when you’re finished to turn ‘Caps Lock’ off.

Step 9: The ‘Windows’ key comes in a number of different designs, such as the example to the right. 

It does exactly the same thing as the Windows button on the taskbar on your computer screen. You can choose to open the ‘Start’ menu by pressing this key or by clicking the button on the taskbar with your mouse.

Step 10: You’ll be told to use the ‘Control’ (Ctrl) and ‘Alternate’ (Alt) keys for some operations. When you do so, keep holding down one or the other key or both keys while you press any other keys . For example, if you press CtrlAlt and Delete all at the same time, a menu will open. To make it disappear, press the ‘Escape’ (Esc) key in the top left-hand 
 corner of the keyboard

How to use mouse in computer :

Step 1: Pick up your mouse and have a look at it.  
At the front (which points away from you), there are two buttons – left and right. You press or, more correctly, ‘click’ these to make things happen.

Most mice also have a wheel in between the buttons that you roll to move up and down the screen – technically called ‘scrolling.

Step 3: Have a click. Use your index finger to click the left button and your middle finger to click the right button.

Step 4:  Try a double-click. This is done quite often on the left button. You have to click twice, as quickly as possible. The first click tells the computer that you are in a particular ‘window’, and the second click tells it that you’re selecting a button or link or whatever to do something in that window. If you click too slowly, the computer just thinks you’re telling it where you are again and again, so do click quickly.


Step 5: Now try a right-click. Just click the right button, paying no attention where the cursor is on the screen. A menu will appear, giving you options. Whenever you right-click, it opens a menu. If you move your cursor off the menu and left-click, the menu will close.
