Question

What are the common features between all the respiratory organs? Explain the

mechanism of gaseous exchange between tissue and blood.

Answer 1

All the respiratory organs have large surface area to get enough oxygen.

All the respiratory organs have thin walls for easy diffusion and exchange of respiratory gases.

All the respiratory organs such as skin, gills and lungs, have a rich blood supply for transporting respiratory gases

The mechanism of gaseous exchange between tissues and blood is as follows: The blood reaching the tissues has higherconcentration of oxygen than in the cells so it gets diffused into the cells.

Answer 2

The respiration is a metabolic process that occurs in all living organisms.

Explanation:

• The respiratory organs exhibit the large surface areas that allows them to absorb and transfer appreciable amount of oxygen to the respiratory tract.
• The respiratory organs are covered with the thin cellular layers which helps in the diffusion of the gases and substances.
• The respiratory organs are the exhibit the rich supply of the blood that facilitates the binding of the gases like carbon dioxide and oxygen as hemoglobin of blood has affinity for these gases.
• Gaseous exchange in case of humans and other higher organisms takes place through the simple diffusion of gases. In the lungs, the oxygen enters the alveolar air diffuses inside the blood vessels through the alveoli and bronchi the air enters into the capillaries. The capillaries transfer the oxygenated blood from the lungs to all the parts of the body including organs, tissues and cells.
