First layer of the heart | Endocardium: responsible for keeping blood from stickin gto the inside of the heart |
Right Atrium | chamber that collects oxygen poor blood returning from the body |
Tricuspid Valve | controls the blood flow from the R atrium to the R ventricle |
Pulmonary Valve | controls the blood flow from the R ventricle through the pulmonary artery and into the lungs |
Right Ventricle | pumps oxygen poor blood to the pulmonary valve |
Aorta | carries oxygen rich blood to the body, arterial blood leaves the heart |
Left Atrium | collects oxygen rich blood returning from the lungs |
Bicuspid valve (mital valve) | controls the flow of oxygen rich blood from left atrium to the left ventricle |
Aorta Valve | controls blood flow from the left ventricle to the aorta |
left ventricle | pumps oxygen rich blood through the aortic valve |
superior vena cave | is one of the two major paths in which the veins from all parts of the body converge to lead to the right atrium to the heart |
