Answer 2

The reason for the the absence of valves in capillaries of human is given below :

The network of the vessels of blood that remains embedded in the tissues of our body is called capillaries. These structures are responsible for transferring glucose and oxygen into the cells and taking away the wastes from the cells.

From the arteries, the entry of blood occurs in the capillaries which happens by the pressure of blood. Then it enters the veins. From here, the blood enters to the heart's right side.

It is clear that the blood travels because of pressure of blood so there is no requirement of valves in the capillaries.
