The mouth is an alimentary canal where digestion begins. There are two types of digestions in the mouth; physical digestion and chemical digestion. Physical digestion is the breakdown of food into smaller pieces with the aid of the teeth. Examples of physical digestion are grinding, chewing, biting, and tearing. Digestion begins as soon as we put food in our mouth. As we chew, we break down food into smaller pieces. Saliva then mixes with the food. Saliva contains enzymes such as Amylase (breakdown of starches into smaller molecules) and lipase (breakdown of fatty acids) which begins with the chemical process. After this, saliva, enzymes (Amylase and lipase), mucus. and food mix to form Bolus and pushed down the esophagus.
The esophagus is

The small intestine can be found between the stomach and the large stomach. It is made up of three regions namely; duodenum, jejunum and ileum. The duodenum which is the longest part and measures about ten to twelve feet breaks down the food whilst the jejunum (about four feet) and ileum (about five feet long) work together to absorb nutrients and send them into the bloodstream.
The liver is an important organ which sits on the right side of the stomach. The liver is said to weigh about 3 pounds and is also reddish in color. It is the production site of bile. Bile is a vital part of the absorption of fat soluble substances such as vitamin A, Vitamin D, Vitamin E and Vitamin K and also responsible for the elimination of waste products from the body.
The pancreas is considered to be an assisting and an abdominal organ which is positioned at the rear of the stomach and surrounded by neighboring organs such as the spleen, small intestine and the liver. It is about 15.24 centimeter long. The pancreas main function is to help regulate blood sugar, break down nutrients and secrete enzymes. To pancreas also produces important hormones such as insulin and glucagon which regulate blood glucose levels in the body. The pancreas secretes about 1,500 milliliters of fluid daily. The fluid is composed of bicarbonate, water and digestive

It is wider than the smaller intestine and 6 feet long. The large intestine is made up of four segments namely; the ascending colon (also known as the cecum), the transverse colon, the descending colon and the sigmoid colon. The main function of the large intestine is to help get rid of leftover food after nutrients have been removed from it. Liquid and salt is eliminated from the waste as it goes through the colon. The waste then passes through the sigmoid colon and is stored there. Once or twice a day when the body is ready to get rid of the waste, it is dumped into the

    This opening allows chyme to enter into the small intestine. The small intestine is composed of 3 parts: duodenum, jejunum and ileum. The duodenum is the only part of the small intestine that continues to break down food with the release of bile. While the stomach releases hydrochloric acid and creates an acidic environment with a low pH, the duodenum is slightly basic with a higher pH. Bile, which is produced in the liver and stored in large quantities in the gall bladder, is released to emulsify and breakdown fats at this point.…

    First step is ingested food is taken into the mouth where it is torn into smaller physical parts by the teeth. The salivary enzymes; amylase and lipase are activated beginning the chemical breakdown of food. Salivary amylase divides starch into smaller glucose molecules. Physically the saliva hydrates and compacts the food for ideal propulsion through the pharynx and esophagus. Propulsion is activated voluntarily when we swallow; the tongue moves towards the hard palate of the mouth thus pushing the food into the pharynx.…
