Study Notes
Blood Types
- Blood type is determined by the presence or absence of specific antigens on red blood cells
- Antigens are substances that stimulate an immune response in the body
- Antibodies are proteins found in plasma that bind to antigens and trigger an immune response
- Clumping occurs when an antibody meets its corresponding antigen
- Blood type A has A antigens and anti-B antibodies
- Blood type B has B antigens and anti-A antibodies
- Blood type AB has both A and B antigens and no antibodies
- Blood type O has no antigens and both anti-A and anti-B antibodies
- Type O blood is the universal donor
- Type AB blood is the universal receiver
Rhesus Factor
- Rhesus factor is a protein found on the surface of red blood cells
- It is either present (positive, Rh+) or absent (negative, Rh-)
- The Rh factor is important during pregnancy
- Rh-negative mothers can develop antibodies against Rh-positive babies
- Rh incompatibility can cause complications for the baby
- Rh-positive blood can be given to Rh-negative individuals
- Rh-negative blood can only be given to Rh-negative individuals
Cardiovascular System
- Arteries carry oxygenated blood away from the heart except the pulmonary artery
- Veins carry deoxygenated blood to the heart except the pulmonary vein
- Pulmonary circuit carries deoxygenated blood from the heart to the lungs and back
- Systemic circuit carries oxygenated blood from the heart to the rest of the body and back
- Heart has four chambers: right and left atrium, right and left ventricle
- Right atrium receives deoxygenated blood from the body
- Right ventricle pumps deoxygenated blood to the lungs
- Left atrium receives oxygenated blood from the lungs
- Left ventricle pumps oxygenated blood to the body
- Tricuspid valve separates the right atrium and ventricle
- Bicuspid (mitral) valve separates the left atrium and ventricle
- Semilunar valves control blood flow from the ventricles to the arteries
Blood Vessels
- Arteries are thick-walled vessels that carry blood away from the heart
- Veins are thin-walled vessels that carry blood to the heart
- Capillaries are the smallest blood vessels that allow exchange of gases and nutrients
- The aorta is the largest artery in the body
- Branches of the aorta include the coronary arteries, carotid arteries, subclavian arteries, and femoral arteries
- Coronary arteries supply blood to the heart
- Carotid arteries supply blood to the head and neck
- Subclavian arteries supply blood to the arms
- Femoral arteries supply blood to the legs
- Deep femoral artery is a branch of the femoral artery and supplies blood to the thigh
Pathway of Blood
- Blood flows from the heart through the arteries, capillaries, and veins, and back to the heart
- Superior vena cava carries deoxygenated blood from the upper body to the heart
- Inferior vena cava carries deoxygenated blood from the lower body to the heart
- Pulmonary artery carries deoxygenated blood from the right ventricle to the lungs
- Pulmonary veins carry oxygenated blood from the lungs to the left atrium
- Aorta carries oxygenated blood from the left ventricle to the rest of the body
