Question

Write a note on any three disorders of circulatory system.

Answer 1

Three disorders of the circulatory system are:

1. Atherosclerosis: Plaque builds up occurs on the walls of the arteries due to which the arteries become narrower and hardened, which disrupts the flow of blood.
   
2. Congestive heart failure: Fluid build up occurs around the heart and the heart pumps blood inefficiently.
   
3. Arrthymia: It occurs when the electrical activity of the heart is disrupted and the heart beats slower or faster than normal.
