Flowchart Science: The Human Body: The Digestive System

Product Information

Digestive Tract Fact #4 – It takes four to five hours for the stomach to completely empty into the small intestine after a meal. Large Intestine The stomach can be functionally divided into proximal and distal motor pumps, which stores food content and pumps chyme along the conduit, respectively. Portions of chyme are passed into the pylorus and into the small intestines. The upper jaw of the frog is fixed and does not exhibit any movement. In contrast, the lower jaw is flexible, allowing it to move up and down. This movement of the lower jaw facilitates the opening and closing of the mouth, enabling the frog to consume food efficiently. Since stomach acid is so potent, its production needs careful supervision. At the start of a meal, gastric function is just starting to warm up and very little stomach acid is secreted. Peristalsis gently begins stretching and squishing the stomach in preparation for incoming food.

A protective layer composed of coarse connective tissue, elastic fibers, fat, lymph vessels, blood vessels, and nerve cells. I nferior mesenteric artery - supplies distal 1/2 of transverse colon, descending colon, sigmoid colon, rectum, anus Size and Shape: The buccal cavity of a frog is large, wide, and shallow, allowing it to accommodate and capture sizable prey. The complex carbohydrate is bulky and adds weight to stool. Bowel movements are easier to pass when solid waste is heavy. Fiber also absorbs water and softens stool as it travels through the digestive tract. Consider increasing your fiber intake if you notice irregularity in bowel movements. Remember, elimination of solid waste can be different for each person. One study found that normal elimination patterns varied from three times per day to three times per week. The digestive system of the human body comprises a group of organs working together to convert food into energy for the body. Anatomically, the digestive system is made up of the gastrointestinal tract, along with accessory organs such as the liver, pancreas and gallbladder. The hollow organs that make up the gastrointestinal tract (GI tract) include the mouth, stomach, oesophagus, small intestine and large intestine that contains the rectum and anus.

Digestion Process

The Digestion of food involves both mechanical and chemical processes as the food is broken down into smaller components. The swallowing reflex allows food from the mouth to be moved into the oesophagus. Here, waves of muscular contractions known as peristalsis move food down this thin-walled tube to a muscular bag known as the stomach. The digestive system of the human body is the sum of the gastrointestinal tract (GIT; also called alimentary canal) and accessory organs (tongue, liver, pancreas, etc.). These two parts together help in the digestion process. A tube that travels through the body in one direction is called the alimentary canal. From the mouth, it extends to the anus. About 9 metres make up the alimentary canal. The mouth, oesophagus, stomach, small intestine and large intestine are examples of continuous muscular tubes that run throughout the body (digestive tract). They are capable of digesting and absorbing nutrients. Mouth

Internal Nostrils: Located at the front of the buccal cavity, near the vomerine teeth, are the internal nares or nostrils. These openings connect the nasal cavities to the buccal cavity and play a role in respiration.The digestive system of a frog is a complex structure designed specifically for its dietary needs and lifestyle. This system is essential for breaking down food, absorbing nutrients, and eliminating waste. Therefore, understanding its components and functions is crucial for a comprehensive knowledge of frog biology.
