Question

4. Differentiate between:
i)Gray matter and White matter
ii) Systemic and Pulmonary circulation​

Answer 1

Answer:

Explanation:

Main Difference – White Matter abd  Grey Matter

White matter and grey matter are two components in the brain and the spinal cord. The brain and the spinal cord consist of nerves that belong to the central nervous system. The major function of the central nervous system is to coordinate the functions of the body based on the information carried by the peripheral nervous system. White matter occurs in both brain and the spinal cord. But, grey matter is the major component of the brain. The main difference between white matter and grey matter is that white matter mainly consists of myelinated axons whereas grey matter mainly consists of cell bodies, axon terminals, and dendrites. The white colour occurs due to the lipid components of the myelin.

Main Difference – Pulmonary and   Systemic Circulation

In mammals, the circulation occurs in two circuits, and blood is circulated through the heart for two times. This type of circulation is called the double circulation. Pulmonary and systematic circulation are the two types of circulations that occur in a double circulation system. The difference between pulmonary and systemic circulation stems from the nature of the blood and the destination of the blood. The main difference between pulmonary and systematic circulation is that pulmonary circulation carries deoxygenated blood from heart to lungs and oxygenated blood back to the heart whereas systemic circulation carries oxygenated blood from the heart throughout the body and deoxygenated blood back to the heart.
