Anatomy+of+the+Heart

By: Kimanh Nguyen

The heart is a muscular organ that pumps blood. It is involved in two types of circulation: systematic circulation and pulmonary circulation.



It is composed of:
 * 1) Myocardium
 * 2) Coronary arteries
 * 3) Coronary veins
 * 4) Septum
 * 5) Superior vena cava
 * 6) Inferior vena cava
 * 7) Right atrium
 * 8) Tricuspid valve
 * 9) Right ventricle
 * 10) Pulmonary valve
 * 11) Pulmonary artery
 * 12) Pulmonary veins
 * 13) Left atrium
 * 14) Mitral valve
 * 15) Left ventricle
 * 16) Aortic valve
 * 17) Capillaries

Structures/Functions: v Myocardium v Coronary arteries v Coronary veins v Septum v Superior vena cava v Inferior vena cava v Right atrium v Tricuspid valve v Right ventricle v Pulmonary valve v Pulmonary artery v Pulmonary vein v Left atrium v Mitral valve v Left ventricle v Capillaries
 * Ø Muscular tissue of the heart
 * Ø Supplies blood to the heart muscle
 * Ø Drain blood from the heart wall and empty into the coronary sinus
 * Ø A partition that separates two chambers of the heart
 * Ø Receives blood from the head/ arms/ chest and empties into the right atrium of the heart
 * Ø Receives blood from lower limbs/ abdominal organs and empties into the posterior part of the right atrium of the heart
 * Ø Right upper chamber of the heart
 * Ø Receives blood from the vena cava
 * Ø Has 3 cusps
 * Ø Located between the right atrium and the right ventricle
 * Ø Allows blood to pass from atrium to ventricle
 * Ø Prevents backflow when the ventricle contracts
 * Ø Chamber located on t he right side of the heart
 * Ø Receives venous blood from the right atrium
 * Ø Pumps the blood into the pulmonary trunk
 * Ø Located between the right ventricle and the pulmonary artery
 * Ø Prevents blood from flowing from the artery back into the heart
 * Ø Carries blood from the right ventricle of the heart to the lungs for oxygenation
 * Ø Carries oxygenated blood from the lungs to the left atrium of the heart
 * Ø The left upper chamber of the heart
 * Ø Receives blood from the pulmonary veins
 * Ø Located between the left atrium and the left ventricle of the heart
 * Ø Composed of 2 cusps
 * Ø located on the left side of the heart
 * Ø receives arterial blood from the left atrium
 * Ø pumps the blood into the aorta
 * Ø Network of blood vessels located between the arterioles and venues
