Document Summary

Lecture 4: general function, organization, and anatomy of circulation: What is the general organization and anatomy of the transport system of the cardiovascular system: a central pump: the heart, a closed system of blood vessels or tubes, the fluid medium through which substances are transported: blood. What does the pulmonary circulation include: the blood vessels that carry blood to and from the lungs. What does the systemic circulation include: all of the blood vessels that carry blood to and from the rest of the body. Why is the heart excluded from both of these circulatory systems: the ter(cid:373) (cid:862)(cid:272)ir(cid:272)ulatory syste(cid:373)(cid:863) refers o(cid:374)ly to the (cid:271)lood vessels. With the lungs, it provides exchanges of carbon dioxide and oxygen between the atmosphere and the blood. Blood is low in oxygen and high in carbon dioxide. What happens in the pulmonary capillaries: the blood picks up oxygen from the air and removes some of the co2.
