Hey mate ☺️

1. Oxygen enters the human body through the nasal passage and reaches the lungs.

2. Numerous alveoli are present in the lungs. These alveoli are surrounded by many blood capillaries. From the alveoli, O2 is taken up by the red blood cells present in the blood capillaries.

3. Similarly, the CO2 from the various tissues is transported to the alveoli.

4. This CO2 is then released through the nasal passage during exhalation.

Alveoli are the sites of exchange of gases. Each lung contains 300−350 million alveoli. These alveoli increase the surface area for gaseous exchange, making the process of respiration more efficient.

Hope it helps you ☺️✌️✌️

simrankamboz778: In human beings, Oxygen is carried from lungs by the respiratory pigment haemoglobin which is present in red blood corpuscles. Haemoglobin has a very high affinity of oxygen. Carbon dioxide is more soluble in water than oxygen. So, most of the carbon dioxide produced during respiration in the human body is transported in the dissolved form in our blood.

O2 and CO2 are transportted by blood and in the alveoli the gqs exchange takes place.

Lungs are provided with cluster of alveoli which increase the surface area for absorption of gases and provided with large number of capillaries. Thus lungs are designed to maximise the gas exchange.

Hopes it helps.
