Question

What happens if the conducting tubes of circulatory system develops a leak? State in brief, how could this be avoided?

Answer 1

Answer:

If conducting tubes of a circulatory system develops a leak, the blood clots. After a leak the number of platelets would get increased that minimize the leakage and inactive thrombin becomes active thrombin in the presence of thromboplasm. This active Thrombin converts the inactive fibrinogen into active fibrin and it results with a clot.

But, if a person does not develop with blood clot, immediate medical attention must be given. Otherwise it may lead to death.

Answer 2

Quantity of dissolved oxygen is fairly low in water as compared to the amount of

oxygen in air. Aquatic organisms therefore have to breath faster than terrestrial

organisms to absorb the required amount of oxygen from the water
