Final answer:
Pulmonary circulation carries blood between the heart and lungs, while systemic circulation carries blood between the heart and body.
Step-by-step explanation:
Pulmonary circulation is a part of the circulatory system that carries blood between the heart and lungs. It is responsible for carrying deoxygenated blood from the heart to the lungs, where it picks up oxygen and returns to the heart. Systemic circulation, on the other hand, carries oxygenated blood from the heart to the rest of the body, supplying oxygen and nutrients to the body tissues.
