Are Pulmonary and Systemic Circulations Important?

Pulmonary circulation moves blood between the heart and the lungs. It transports deoxygenated blood

to the lungs to absorb oxygen and release carbon dioxide. The oxygenated blood then flows back to the heart. Systemic circulation moves blood between the heart and the rest of the body.

Is pulmonary or systemic circulation more important?

Systemic circulation as a whole is a higher pressure system than pulmonary circulation simply because systemic circulation must force greater volumes of blood farther through the body compared to pulmonary circulation.

Why pulmonary circulation is important?

The pulmonary circulation has many essential functions. Its primary function involves the exchange of gases across the alveolar membrane which ultimately supplies oxygenated blood to the rest of the body and eliminates carbon dioxide from the circulation.
