Question

1) What happen if platelets were absent in the blood

2) What are capillaries? State the function performed by them?​

Answer 1

Answer:

Hint:If there are no platelets in the blood, our skin would now no longer be capable of preventing the bleeding if we are wounded or cut. ... The vitamin K, clotting factors, calcium ions and the platelets are important elements for the formation of a blood clot. If there are no platelets, there can be no clot formation.

Capillaries, the smallest and most numerous of the blood vessels, form the connection between the vessels that carry blood away from the heart (arteries) and the vessels that return blood to the heart (veins). The primary function of capillaries is the exchange of materials between the blood and tissue cells.

Answer 2

Answer:

Hi..

Explanation:

1 If there are no platelets in the blood, our skin would now no longer be capable of preventing the bleeding if we are wounded or cut. ... The vitamin K, clotting factors, calcium ions and the platelets are important elements for the formation of a blood clot. If there are no platelets, there can be no clot formation.

2 Capillaries are the smallest of blood vessels. They serve to distribute oxygenated blood from arteries to the tissues of the body and to feed deoxygenated blood from the tissues back into the veins. The capillaries are thus a central component in the circulatory system, essentially between the arteries and the veins.
