Answer 1

What is Homeostasis?

The ability to keep a stable internal environment within the cell or a body is called Homeostasis.

Examples of Homeostasis :

1) Control of Body Temperature :

In humans normal body temperature is around 37 degrees celcius. The body temperature regulation is controlled by hypothalamus in the brain. Feedback about body temperature is carried to the brain through bloodstream which in return results in adjustments of breathing rate, metabolic rate.

2) Blood sugar levels :

The basic form of sugar in human body is glucose which is directly used by the body. The human body has to maintain proper sugar levels to ensure a person remains healthy. If the glucose levels are high the Pancreas release insulin and if it is low the liver converts glycogen into glucose and maintains its level.

3) Maintenance of blood pressure :

Whenever the blood pressure increases the heart senses it and sends signals to the brain. The brain sends appropriate feedback signals back to the heart and the heart slows down decreasing its pumping. If the blood pressure is too low the heart speeds up.

4) Maintenance of calcium levels in blood :

Whenever calcium levels decreases in the blood stream parathyroid releases hormones and makes it available in proper amounts. And when it's too low, thyroid secretions fixes the bone calcium and Lowers the blood calcium levels.
