TYPES OF ANEMIA
- Aplastic anemia
- Hemolytic anemia
- Iron deficiency anemia
- Pernicious anemia
- Sickle cell anemia
- Aplastic anemia - bone marrow fails to produce RBCs, WBCs, and platelets
- Hemolytic anemia - RBCs are destroyed (-LYTIC) and bone marrow cannot compensate for their loss
- Iron deficiency anemia - Low iron levels lead to low hemoglobin or deficiency of RBCs
- Pernicious anemia - Mucous membrane of stomach fails to produce substance (intrinsic factor) that is necessary fr absorption of Vitamin B12 and proper formation of RBCs
- Sickle cell anemia - RBCs assume an abnormal crescent shape; they clump together causing clots that block blood vessels

Describe the process by which blood enters and leaves the heart.
- Blood enters through the RIGHT ATRIUM from the venae cavae
- Blood passes down through the TRICUSPID VALVE into the RIGHT VENTRICLE
- Blood then travels OUT TO THE LUNGS where is loses CO2 and picks up oxygen
- Blood RETURNS to the heart through the LEFT ATRIUM
- Blood passes down through MITAL VALVE (bicuspid) ito the LEFT VENTRICLE
- Blood is then pumped superiority and out of the heart through the AORTA into the rest of the body.
The vena cava is on the right posterior side of the heart. It extends superiority and inferiorly.
The aorta is the largest heart artery. It is inferior to the rest of the heart, connecting inferiorly to the left ventricle.
Right side = oxygen poor
