What is the name of the very long coiled tube-like organ that controls the flow of the food?
The long coiled tube-like organ that controls the flow of food is called the intestine, specifically the small intestine and the large intestine. The small intestine is responsible for nutrient absorption, while the large intestine focuses on water absorption and waste formation. Together, they play a crucial role in the digestive system.
What is the role of the villi in the small intestine.?

What are the three sections of the small intestine and what role does each section play in digestion or absorption?
The 3 parts of the small intestine are: the Duodenum, the Jejunum, and the Ileum.The small intestine is the site where most of the nutrients from ingested food are absorbed. The inner wall, or mucosa, of the small intestine is lined with simple columnar epithelial tissue.
What is the group of lymph nodes in the small intestine?
The group of lymph nodes in the small intestine is called the mesenteric lymph nodes. They are located in the mesentery, the tissue that attaches the small intestine to the back of the abdominal wall. Mesenteric lymph nodes play a crucial role in immune responses and help filter and trap pathogens and other harmful substances in the lymphatic system.
What role does jejunum play in digestion?
It is involved in absorption in the small intestine. It is the middle portion of the small intestine, and it is aprox. 2 meters long.
Peyer's patches are found in the submucosa of the distal end of the small intestine?
Peyer's patches are clusters of lymphoid tissue located in the mucosa of the small intestine, particularly in the ileum. They play a crucial role in the immune system by monitoring and responding to pathogens that enter the gut through the digestive tract.
What role does your small intestine play in food digestion process?

Following the ileum of the small intestine is the ileocecal valve, which separates the small intestine from the large intestine. The duodenum is separated from the stomach by the pyloric sphincter.
Where in the body is the largest single collection of lymphoid tissue?
The largest single collection of lymphoid tissue in the body is located in the small intestine, specifically in the lining of the small intestine called Peyer's patches. These patches play a crucial role in immune responses and help protect the body from pathogens that may enter through the digestive tract.
