Circulatory Pathways Anatomy And Physiology Ii Pulmonary circuit: system of blood vessels that provide gas exchange via a network of arteries, veins, and capillaries that run from the heart, through the body, and back to the lungs. pulmonary trunk: single large vessel exiting the right ventricle that divides to form the right and left pulmonary arteries. Figure 20.6.1 20.6. 1: interaction of the circulatory system with other body systems. as you learn about the vessels of the systemic and pulmonary circuits, notice that many arteries and veins share the same names, parallel one another throughout the body, and are very similar on the right and left sides of the body.

The heart is a muscle and, like any muscle, it responds dramatically to exercise. for a healthy young adult, cardiac output (heart rate × stroke volume) increases in the nonathlete from approximately 5.0 liters (5.25 quarts) per minute to a maximum of about 20 liters (21 quarts) per minute.
