Question

How is blood circulation related to respiration?​

Answer 1

Pulmonary circulation facilitates the process of external respiration: Deoxygenated blood flows into the lungs. It absorbs oxygen from tiny air sacs (the alveoli) and releases carbon dioxide to be exhaled. Systemic circulation facilitates internal respiration: Oxygenated blood flows into capillaries through the rest of the bod.

Answer 2

The circulatory and respiratory systems work together to circulate blood and oxygen throughout the body. Air moves in and out of the lungs through the trachea, bronchi, and bronchioles. Blood moves in and out of the lungs through the pulmonary arteries and veins that connect to the heart.
