Question

(i) Identify any two parts from the above diagram which carry oxyge
nated and
deoxygenated blood.
ii) Explain the process of double circulation with the help of a flow chart.​

Answer 1

Answer:

Artries and veins.

DOUBLE CIRCULATION IS THAT THE PASSING OF BLOOD FROM HEART TWO TIMES ONE TIME IN OXYGENATED FORM AND ONE IN DEOXYGENATED FORM.

Answer 2

Answer:

1. Pulmonary artery carries the deoxygenated blood into lungs for purification process.  

2. Later, the blood get purified (oxygenated) in the lungs and leaves into the pulmonary vein.  

Explanation:

The “heart” is the vital organ for the blood circulation and the double circulation.

The blood flows into two routes. They are “One route for oxygenated blood to flow" and another route for "deoxygenated blood. “

When the blood passes twice through the heart during one complete cycle is called “double circulation.”

The most of the mammals which includes humans will utilize the double circulatory system.

Flow chart:  

Right auricle---->right ventricle--->lungs--->left auricle--->left ventricle--->body organs---->right auricle.

This makes a complete cycle.
