Question

What is the main interaction between the respiratory and circulatory

systems?
A. They send hormones to each other.
B. They exchange oxygen and carbon dioxide.
C. They communicate through neuroendocrine cells.
D. They exchange information across synapses.

Answer 1

Answer:

B. The exchange of oxygen and carbon dioxide.

Step-by-step explanation:

The respiratory system is responsible for taking in oxygen from the air and expelling carbon dioxide, while the circulatory system is responsible for transporting oxygen-rich blood from the lungs to the rest of the body and bringing back carbon dioxide-rich blood to the lungs for removal. The exchange of oxygen and carbon dioxide occurs at the alveoli in the lungs, where the respiratory system interfaces with the circulatory system via the pulmonary capillaries. This exchange ensures that the body's cells have a constant supply of oxygen for cellular respiration and that carbon dioxide is efficiently removed from the body.
