Question

How are the respiratory gases, oxygen and carbon dioxide

transported in our body? class 10

give proper answer​

Answer 1

Explanation:

Carbon dioxide molecules are transported in the blood from body tissues to the lungs by one of three methods: dissolution directly into the blood, binding to hemoglobin, or carried as a bicarbonate ion. Several properties of carbon dioxide in the blood affect its transport.

Answer 2

During the process of circulation, the carbon dioxide rich blood has to reach the lungs for CO2 to be removed and oxygenated blood from the lungs has to reach the heart for O2 to be distributed to all parts of the body.

This process takes place step by step as follows:-

1. Oxygen rich blood from the lungs is brought to the relaxed left atrium by the pulmonary veins.
2. The left atrium contracts and transfers blood to the left ventricle which expands.
3. The left ventricle contracts pumping the O2 rich blood into the aorta which transports it throughout the body.
4. De-oxygenated blood from the body is brought by the superior and inferior venacavae to the right atrium which expands.
5. The right atrium contracts and transfers the blood to the right ventricle which expands.
6. The right ventricle contracts pumping the blood into the pulmonary arteries which carries it to the lungs for oxygenation.
