Anatomy and functions of the heart
| Question | Answer |
|---|---|
| Outermost Layer of the heart | Epicardium: thin layer of serous membrane that helps to lubricate and protect the outside of the heart |
| Second layer of the heart | Myocardium: muscular middle layer that contains the cardiac muscle tissue. the part of the heart responsible for pumping blood |
| 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 |
