Question

Ileocecal valve is present in between
(a) Colon and large intestine
(b) Colon and small intestine
(c) Stomach and small intestine
(d) Cardiac, stomach, and fundus

Answer 1

Hint: A sphincter is a special round muscle that usually maintains contraction of a natural body passage or opening and which relaxes as essential by regular physiological working. Sphincters are seen in many animals, especially mammals.

Complete step by step answer:
The Ileocecal valve is a unique sphincter muscle that protects the passage of the large intestine. It is found where the ileum of the small intestine joins the colon of the large intestine and maintains the flow between the colon and ileum to prevent the bacteria- loaded contents of the colon from infecting the small intestine.

Additional information:
- The end part of the gastrointestinal tract is the large intestine where before excretion the feces is stored. The large intestine is composed of 8 major parts – Cecum, appendix, ascending colon, transverse colon, descending colon, sigmoid colon, rectum, and anal canal.
- Other than the temporary storage of feces, the large intestine is a site for the absorption of electrolytes and water. The length of the large intestine is 1 to 1.5 meters, which is home to a variety of microscopic gut microbiomes.
- Major portion of digestion occurs in the small intestine, where all the nutrients are absorbed by the finger- like structures, known as the villi. Villi increases the surface area of the small intestine which aids in more absorption of nutrition to the bloodstream.
So, the correct answer is ‘Colon and Small Intestine’.

Note:
- Failure or damage of Alpha and Beta cells of the pancreas to produce insulin causes diabetics (high sugar content in the blood) .
- Small intestine is lengthier than the large intestine, but in terms of diameter, the large intestine is bigger than the small intestine.
- Sphincter muscles are present in the anal opening also to control the movement of feaces which gets released out of the body known as the anal sphincter. The average length of the small intestine is 22 feet which is three times the length of an average human being.
