Answer:
<h2>Capillaries interact with the respiratory system through the <u>alveoli</u> present in the lungs.</h2>
Explanation:
Lungs and capillaries are important parts of respiratory system which allows the process of breathing through which living body take in oxygen from the atomsphere. The lungs bring oxygen into the body and the process is called inhalation and releases carbon dioxide out of the body and the process called exhalation.
The walls of capillaries are in contact with the walls of alveoli, When the person breath in it takes oxygen, the oxygen transferred to the red blood cells and it further releases carbon dioxide. The oxygenated blood is then move to the heart and other body parts from the lungs.
Hence, this is how the capillaries interact with the respiratory system.
Aerobic respiration is more effective.
Answer:
oxygen gas is most abundant in the atmosphere
