The right and left sides of the heart work together. The pattern described below is repeated over and over, causing blood to flow continuously to the heart, lungs, and body.

Right side

Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium.
As the atrium contracts, blood flows from your right atrium into your right ventricle through the open tricuspid valve.
When the ventricle is full, the tricuspid valve shuts. This prevents blood from flowing backward into the atria while the ventricle contracts.
As the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs where it is oxygenated.

Left side

The pulmonary vein empties oxygen-rich blood from the lungs into the left atrium.
As the atrium contracts, blood flows from your left atrium into your left ventricle through the open mitral valve.
When the ventricle is full, the mitral valve shuts. This prevents blood from flowing backward into the atrium while the ventricle contracts.
As the ventricle contracts, blood leaves the heart through the aortic valve, into the aorta and to the body.

Once blood travels through the pulmonic valve, it enters your lungs. This is called the pulmonary circulation. From your pulmonic valve, blood travels to the pulmonary artery to tiny capillary vessels in the lungs.

Two major coronary arteries branch off from the aorta near the point where the aorta and the left ventricle meet:

Right coronary artery supplies the right atrium and right ventricle with blood. It usually branches into the posterior descending artery, which supplies the bottom portion of the left ventricle and back of the septum with blood.
Left main coronary artery branches into the circumflex artery and the left anterior descending artery. The circumflex artery supplies blood to the left atrium, side, and back of the left ventricle, and the left anterior descending artery supplies the front and bottom of the left ventricle and the front of the septum with blood.

Describe how blood is pumped through the heart from the entry of deoxygenated blood through the venae cavae to the exit of deoxygenated blood out of the aortae, taking into account the roles of the heart valves and cardiac conductance in the flow of blood.

Trace the path of a single erythrocyte through the heart from Superior Vena Cava to Aorta. Describe the characteristics of each chamber as the erythrocyte passes through. For each feature mentioned, include its location and a brief comment describing its function. Use terms like endocardium, myocardium, the names of great vessels, auricle, papillary muscle, pectinate muscle, types/names of valves, fossa ovalis, chordae tendineae, interventricular septum. (Note: Include the pulmonary circuit in your path, but do not detail the pulmonary circuit...

Oxygen-rich blood bound for the body tissues leaves the heart through the aorta, the major blood vessel emerging from the heart. It branches out to the arteries, which in turn branch into smaller vessels called arterioles (little arteries). These then branch into tiny, thin-walled capillaries. Blood travels slowly as the red blood cells squeeze through tiny capillaries. The radius of the aorta is approximately 9.8 mm and the speed of the blood there is 30 cm/s. A typical capillary has...
