Solution

The correct option is D Statements (a), (b) and (d)
Small Intestine: Principal organ for absorption of nutrients. The digestion is completed here and the final products of digestion such as glucose, fatty acids, glycerol and amino acids are absorbed through the mucosa into the blood stream and lymph.

Reflex action for vomiting is controlled by medulla.

Diarrhoea: The abnormal frequency of bowel movement and increased liquidity of the faecal discharge is known as diarrhoea. It reduces the absorption of food.

The mucosa of stomach has gastric glands. Gastric glands have three major types of cells namely -
(i) Mucus neck cells which secrete mucus;
(ii) Peptic or chief cells which secrete the proenzyme pepsinogen; and
(iii) Parietal or oxyntic cells which secrete HCl and intrinsic factor(factor essential for absorption of vitamin B12).
