$\huge \mathbb \purple{ANSWER}$

I) Gooseflesh: Answer in pic kyuki vo Answer send ni ho paara!

II) Hydrochloric acid performs the following functions in the stomach:

→ It kills bacteria present in the food by mixing up with the food.

→ To act on proteins, it activates pepsin.

4)

$\sf \purple{(i)peristalsis↓}$

When the food has been swallowed, it moves down the oesophagus through the progressive wave of contraction and relaxation of muscles in its wall to reach the stomach. Such a movement of muscles is called peristalsis.

$\sf \purple{(ii)Vasodilation↓}$

Vasodilation is the widening of your blood vessels. It happens when smooth muscles found in the walls of arteries or large veins relax, allowing the blood vessels to become more open. This leads to an increase in blood flow through your blood vessels as well as a decrease in blood pressure.

$\sf \purple{(iii)Diaphragm↓}$

A large muscular sheet called diaphragm forms the floor of the chest cavity. Breathing involves the movement of diaphragm and the rib cage.

$\sf \purple{(iv)Pylorus↓}$

The pylorus is the furthest part of the stomach that connects to the duodenum. The pylorus is a valve that opens and closes during digestion.

$\sf \purple{(v)Balanced \: diet↓}$

A diet consisting of a variety of different types of food and providing adequate amounts of the nutrients necessary for good health.
