Anatomy Of The Heart Valves And The Path Of Blood Through The Heart
The heart has two kinds of valves atrioventricular and semilunar valves. The valves are located between the atria and ventricles and in the two arteries that empty blood from the ventricles.

The left atrium receives oxygenated blood through the pulmonary veins from the lungs.
Anatomy of the heart valves and the path of blood through the heart. There are four heart valves within the heart. The aorta is the largest artery in the body. Normal heart anatomy and physiology need the atria and ventricles to work sequentially contracting and relaxing to pump blood out of the heart and then to let the chambers refill.
As the right ventricle fills 70 flow is passive through the relaxed right atrium. Allows oxygenated blood to flow from the left ventricle into the aorta to be circulated out of the body to all the tissues. Valves are structures that make sure there is a one way forward flow thus keeping the blood from passing backward.
Blood flows from the right atrium into the right ventricle through the open right av valve or tricuspid valve. When the mitral valve is closed the left ventricle pushed this blood into the aorta. The left atrium contracts and pushes the blood into the left ventricle through the left atrioventricular valve.
They are composed mostly of fibrous connective tissue that extends from the heart walls. These valves open and close during the cardiac cycle to direct the flow of blood through the heart chambers and out to the rest of the body. The four valves of the heart.
The right atrium receives deoxygenated blood through the superior and inferior vena cavas from the body and pumps it to the right ventricle through the tricuspid valve which opens to allow the blood flow through and closes to prevent blood backing up the atrium. Four valvesmaintain the unidirectional flow of blood through the heart. When the heart beats oxygen poor blood enters the right atrium through the superior and inferior venae cavae and the coronary sinus.
Blood from the body goes back to the heart via the right atrium from the right atrium blood will then pass through a valve called the tricuspid valve to go to the next chamber. The heart has four valves to ensure that blood only flows in one direction. The heart pumps blood from the left ventricle into the aorta through the aortic valve.
The left atrium is the first chamber of the heart to receive oxygenated blood. From here the blood is pushed through the mitral valve into the left ventricle. This is between the left ventricle and the aorta.
When blood leaves each chamber of the heart it passes through a valve that is designed to prevent backflow of blood. The left ventricle pushes oxygenated blood through the aortic semilunar valve into the aorta from which blood is distributed throughout the body. This is between the left atrium and the.
Heart valves are formed from elastic connective tissue which provides the flexibility needed to open and close properly. The tricuspid and mitral valves are also known as the atrioventricular valves. The left ventricle receives oxygenated blood from the left atrium.
