Question

5 differences between single and double circulation? ?

Answer 1

The main difference between single circulatory systems and double circulatory systems is that in the case of single circulatory systems, blood passes through the heart only once on each circuit around the whole of the blood circulation system of the animal.

Answer 2

Answer:

a) single circulation - blood flows only through the heart during one cycle of passage through the body.

double circulation - blood flows twice through the heart during one cycle of passage through the body.

b) single circulation - occurs only in fishes

double circulation - occurs in all vertebrates other than fishes.

c) single circulation - only venous blood passes through the heart

double circulation - mixed  oxygenated blood  passes through the heart.

I KNOW ONLY THREE DIFFERENCES SO, I GAVE THIS MUCH ONLY.
