Answer 2

Answer:

The exchange of gases between inhaled air and blood is referred as External respiration.

Explanation:

Respiration is the exchange of gases between the atmosphere, blood, and body tissue cells. The respiratory and circulatory systems work together to supply the body with oxygen and remove carbon dioxide.  

Four processes are involved in respiration:  

1. Pulmonary ventilation or breathing - It is the movement of air into and out of the lungs.  

2. External respiration - It is the exchange of gases between the air sacs or alveoli of the lungs and the blood.  

3. Transport of respiratory gases - Oxygen and carbon dioxide are transported to and from the lungs and body tissue cells by the blood.  

4. Internal respiration - It is the exchange of gases between the blood and the body tissue cells.  

The organs and structures of the respiratory system are the nose, pharynx, trachea, bronchi, and lunqs.
