Study Notes

Blood Vessels and Heart Function

Veins return blood to the heart.
Arteries convey blood away from the heart.

Purpose of Bypass Surgery

The purpose of bypass surgery is to redirect blood flow around a blocked or narrowed section of a coronary artery, restoring blood flow to the heart muscle.

Conducting System of the Heart

The conducting system of the heart is a network of specialized cells that generate and conduct electrical impulses, regulating the heartbeat.

Autonomic Innervation of the Heart

Sympathetic innervation stimulates the heart, increasing heart rate and contractility.
Parasympathetic innervation inhibits the heart, decreasing heart rate and contractility.
