Structures that affect circulation - heart and systolic/diastolic BP

By: HWC, Views: 6549

• Heart generates blood pressure. • Arterioles produce resistance thereby regulating blood flow to tissues. • Veins store blood; kidneys regulate blood volume; both affect venous return and cardiac output. ■ Contractions of the ventricles determine blood pressure, which drives th...

baroreceptors

By: HWC, Views: 6414

A baroreceptor is a specialized nerve ending that allows your brain to sense blood flow and blood pressure in the major blood vessels of your circulatory system. • The aortic arch carries blood to the body. • The common carotids carry blood to the head. • Baroreceptors measure chang...
