Question

write the features of respiratory organs for exchange of gaseswrite the features of respiratory organs for exchange of gases

Answer 1

Answer:

Inside the lungs, oxygen is exchanged for carbon dioxide waste through the process called external respiration. This respiratory process takes place through hundreds of millions of microscopic sacs called alveoli. Oxygen from inhaled air diffuses from the alveoli into pulmonary capillaries surrounding them.

Answer 2

• All the respiratory organs have large surface areas to get enough oxygen.
• All the respiratory organs are thin-walled for easy diffusion of gases and substances.
• All the respiratory organs (like the skin, lungs, gills) have a rich supply of blood for transporting respiratory gases.
