left auricle and left ventricle in higher vertebrates..

Answer 2

Option (c) is the right answer

Systematic heart refers to left auricle and left ventricle of vertebrates.

- Every human body consists of two main circulatory systems ,i.e, systematic circulation and pulmonary circulation.

- Blood vessels are the important part of both the circulations which take place in any living organism.

- In the process of systematic circulation the heart carries the pure blood (oxygenated) from the left ventricle corresponding to the arteries then to the tissue capillaries.

- Now the deoxygenated blood found in the tissue capillaries are returned back through a pathway of veins to the right atrium of the heart.
