Digestion details by Louise Grogan https://padlet.com/louisespc1/r0eykyh4i5eb From mouth to anus! en-us 2017-08-02 02:56:23 UTC 2017-08-03 02:20:55 UTC hello@padlet.com colon https://padlet.com/louisespc1/r0eykyh4i5eb/wish/179914600 The colon is a long, coiled, tube-like organ that removes the water from digested foods. The remaining material which is waste, moves out of the colon and leaves the body through the anus. The colon is more commonly known as the large intestine. The colons vital function is to remove the water and ions(salts). The inside of the colon does not contain villi, but the surface area is increased by having folds on the inside of the colon. Once the colon has absorbed the ions and water from digested food what remains is called faeces. It is transported to the rectum where it is excreted by the anus. ;) ]]> 2017-08-02 03:01:54 UTC https://padlet.com/louisespc1/r0eykyh4i5eb/wish/179914600 Digestion in the Mouth https://padlet.com/louisespc1/r0eykyh4i5eb/wish/179914637 Food begins digestion in the mouth, mechanically by chewing, and chemically by enzymes. Mastication (chewing) along with saliva mechanically breaks down food by  grinding it up and softening it enough to swallow. Starches begin to chemically digest in the mouth because of the enzyme amylase in the saliva which works alongside chewing. This is why sometimes starches start tasting sweet after chewing, because they have already started to turn into glucose.]]> 2017-08-02 03:02:06 UTC https://padlet.com/louisespc1/r0eykyh4i5eb/wish/179914637 Appendix https://padlet.com/louisespc1/r0eykyh4i5eb/wish/179914640 why do humans have an appendix?
In the past it could have been useful when we ate plant material. In herbivores it helps break down plant material. But an appendix is hardly significant in modern humans and it is often removed to avoid complications due to infection.

what is appendicitis?
Appendicitis is a condition in which the appendix becomes inflamed and filled with pus causing pain. if blockage continues, bacteria begin to leak out through the dying walls of the appendix and pus forms, this could lead to a burst appendix blood poisoning and death.

The gall bladder stores bile made in the liver. Bile emulsifies lipid into smaller droplets. This increases the surface area of lipids and therefore increases the action the action of the enzyme pancreatic lipase.
The pancreas produces and discharges enzymes, these include trypsin and chymotrypsin, lipases that converts lipid into fatty acids and glycerol and pancreatic amylase which completes the digestion of carbohydrates. The pancreas also produces chemicals including sodium bicarbonate to neutralise stomach acid.
The hormone insulin from the pancreas controls sugar levels in the blood.

The ileum is the middle section of the small intestine, the muscular walls of the ileum allow the food to move along through the process of peristalsis.
 Villi and microvilli, which are finger- like branches on the walls of the ileum, diffuse glucose and nutrients through their thin walls, into capillaries, and thus into the blood stream. The Lymph capillary is a vessel in the centre of the Villi. Its purpose is to absorb fatty acids into the lymph system which heps fight infection, and thus keeps you healthy.

The stomach is a muscular hollow organ which can hold up to 4L of liquids. CHEMICAL DIGESTION:The stomach is lined with holes called gastric pits. These pits secrete gastric fluid. This gastric fluid contains HCL, pepsin' mucus. The HCL is a strong acid (pH2) that is able to dissolve many types of food. It also kills harmful microorganism and exposes the protein molecules for pepsin to work. Pepsin catalizes the breakdown of proteins. Mucus forms a protective layer that stops the acid digesting the stomach. The stomach also breaks down food with the churning muscles called mechanical digestion. ]]> 2017-08-02 03:09:40 UTC https://padlet.com/louisespc1/r0eykyh4i5eb/wish/179915387 Liver https://padlet.com/louisespc1/r0eykyh4i5eb/wish/180001534 Hepatic Portal Vein: 
The Hepatic Portal Vein carries glucose to the liver, from there it is sent to the muscles of the body to give them energy.
Glucose and Glycogen:
Glycogen is excess glucose which is stored and ready to be converted back to glucose by the liver to provide the muscles with energy.
Deamination: 
The liver regulates the level of amino acids that are in the blood. Amino acids cannot be stored so they are deaminated and converted into glucose . 
Fatty Acids:
The liver converts excess carbs and protein into fatty acids and triglycerides which are stored as body fat. Body fat can be burned off as energy but an inactive lifestyle will mean the fat stays stored, which can cause a person to become over weight.
