Principles of Homeostasis

Question 1

What is the definition of homeostasis?

Answer 1

The process of regulating the internal condition of the body in order to function on a day to day basis.

Question 2

Why is homeostasis important in enzymes?

Answer 2

Enzymes control all the functions of a cell. The functioning individual cells is vital for the way tissues, organs and whole organisms work. It is important. It is important to respond to changes in the internal environment to maintain optimum conditions for the cellular enzymes.

Question 3

Give examples of internal conditions that are controlled inside of the body.

Answer 3

1. Body temperature
2. Water content in the body
3. Blood glucose concentration.

Question 4

What are the purpose of receptors cells?

Answer 4

Cells that detect changes in the internal or external environment. A change in the environment is called a stimulus. Receptors may be part of the nervous or hormonal control systems of the body.

Question 5

What are the purpose of coordination centres?

Answer 5

Areas that receive and process the information from receptors. They send out signals and coordinate the response of the body. They include the brain, which acts as a coordination centre for the nervous system and parts of the hormonal system, the spinal cord, and some organs such as the pancreas.

Question 6

What are the purpose of Effectors?

Answer 6

Muscles or glands that bring about responses to the stimulus that has been received. These responses restore conditions in the body to the optimum levels.

Question 7

What is the order in which the effectors, coordination centres and receptors go into?

Answer 7

Receptors ——-> Coordination centres ——–>Effectors
