Question

Difference between block diagram of single and double circulation

Answer 1

Differences between a double and single circulatory system
1. The heart is divided into four chambers in a double circulatory system, and only two chambers in a single circulatory system
2. In a double circulatory system the heart pumps deoxygenated and oxygenated blood through its chambers. In the single circulatory system the heart only pumps deoxygenated blood.
3. In a double circulatory system, there are two circuits of blood flow, where as in a single circulatory system, there is only one. Hope this helps!

$\Large\fbox{\color{purple}{ SOLUTION }}$

$\Large\mathcal\pink{DOUBLE \: CIRCULATION}$

Deoxygenated blood from the body tissues is poured into right atrium. Contraction of heart forces it into right ventricle. From right ventricle deoxygenated blood flows to the lungs through pulmonary artery.oxygenated blood from lungs is return into left atrium and then into left ventricle. The left ventricle forces the oxygenated blood to the whole body.thus, for making one complete round of circulation circuit around all body parts, the blood passes through the heart twice.

the pathway of blood from heart to the lungs and back to the heart is called pulmonary circulationand the pathway of blood from heart to the body and back to hurt is called system circulation this is known as double circulation of blood

$\Large\mathcal\orange{SINGLE \: CIRCULATION }$

Single circulation is the type of circulatory system that occurs in fishes in which the blood passes only one through the heart, in each complete circuit of the body compare double circulation “ single circulation a dictionary of biology

In single circulation there is no pulmonary circulation and there is only system circulation . These organism have two chambered heart and the blood is circulated one time from heart to the body
