supply blood to the heart. if cut off leads to atherosclerosis
renal circulation
supplies blood to the kidneys
time of white blood cell that engulfs invading microorganisms
produced by white blood cells that destroy bacteria and viruses

the number of white blood cells doubles
fragments of large cells that were formed in blood marrow... essential to formation of blood clots
sinoatrial node

series of pressure waves within an ARTERY caused by the contractions of the left ventricle
radial artery
sides of thumb, most common site to take pulse
open in only one direction

ex: tricuspid valve- right side of heart
bicuspid valve- left side of the valve
Describe the steps of circulation in the heart
1. The right atrium sends deoxygenated blood into the right ventricle

2. The right ventricle forces the blood into the pulmonary arteries

3. The pulmonary artery sends the blood to the lungs.

4. In the lungs, the CO2 diffuses out of the blood and the oxygen diffuses in.

5. the oxygenated blood returns to left atrium.

6. the oxygenated blood is then pumped into the left ventricle

7. forced into aorta

8. spread to all parts of the body, then comes back to the right atrium
