Blood Disorders Anemia –Results in low levels of red blood cells. Not as much oxygen can get to the tissues of the body. –Sickle cell anemia Hemophilia –The ability to stop bleeding is inhibited due to a lack of or low levels of clotting factors.

1) Oxygen-poor blood flows from the body into the right atrium. 2) Blood flows through the right atrium into the right ventricle. 3) The right ventricle pumps the blood to the lungs, where the blood releases waste gases and picks up oxygen through the alveoli. 4) The newly oxygen-rich blood returns to the heart and enters the left atrium. 6) The left ventricle pumps the oxygen-rich blood to all parts of the body. 5) Blood flows through the left atrium into the left ventricle.

Blood Components of Blood –Plasma Makes up about 55 percent of blood volume. –Three kinds of cells. Red Blood Cells (erythrocytes) –Make up about 44 percent of blood volume. –Carry Oxygen to cells in the body. »Hemoglobin White Blood Cells (leukocytes) –Make up One percent of total blood volume. –Protect the body from infection. Platelets –Helps blood clot.
