Question

The digestive system processes food into usable and unusable materials. The usable materials are sent to the body’s cells as food and unusable material goes into the
(a)Pancreas to await disposal
(b)Right ventricles to await disposal
(c)Large intestine to await disposal
(d)Small intestine to await disposal

Answer 1

The unusable materials are excreted or disposed of out of the body in the form of faeces through the rectum. This part is also known as the ‘large bowel’ of the digestive system.

Complete answer:
The large intestine is the final part of the gastrointestinal tract where the faeces is stored before disposal. The large intestine is divided into 8 major parts – Cecum, appendix, ascending colon, transverse colon, descending colon, sigmoid colon, rectum, and anal canal.

Additional Information: -Other than the temporary storage of faeces, 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.
Pancreas: Pancreas makes pancreatic juices that contain enzymes that break down sugars, fats, and carbohydrates. Pancreas also aids the digestive system by providing hormones.
Right ventricles: The right ventricle is one out of the four cardiac chambers which are in the lower right part of the heart.
-The right ventricle pumps oxygen exhausted blood to the lung for the exchange of gases.
Small intestine: 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 the ‘Large intestine to await disposal’.

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.
-The average length of the small intestine is 22 feet which is three times the length of an average human being.
