| A | B |
|---|
| cardiovascular | having to do with the heart and vessels |
| right ventricle | bottom chamber of the heart which pumps blood to the lungs |
| right atrium | the upper chamber that receives deoxigenated blood |
| left atrium | the upper chamber that recieves oxygenated blood |
| plumonary circulation | movement of blood through the heart, to the lungs and back to the heart |
| left ventricle | lower chamber of the heart which pumps blood to be distributed to the entire body |
| systemic circulation | movement of blood from the heart to the various tissuies of the body and back to the heart |
| coronary circulation | flow of blood to tissues of the heart |
| atria | both upper chambers of the heart |
| artery | any blood vessel that moves blood away from the heart |
| vein | a blood vessel that moves blood toward the heart |
| capillaries | microscopic blood vessels that have walls that are only one cell thick |
| aorta | largest artery of the body |
| vena cava | largest vein of the body |
| pulmonary artery | an artery that actually carries oxygen poor blood |
| pulmonary vein | type of vein that carries oxygen rich blood |
| valve | found between an atrium and a ventricle |
| arteriole | very small, thin-walled artery |
| venule | very small, thin vein |
| capillary bed | exchange of oxygen, carbon dioxide, food, and waste take place here |
| right atrium | first part of the heart that blood enters from the body |
| left ventricle | pumps blood into the aorta |
| right ventricle | pumps blood into the pulmonary artery |
| inferior vena cava | sends deoxygenated blood from the lower portion of body to the right atrium |
| tricuspid valve | keeps blood from backing up from the right ventricle to the right atrium |
| bicuspid valve | keeps blood from going backwards into the left atrium |
| oxygen | picked up in lungs and brought back to heart by pulmonary vein |
| carbon dioxide | given up to blood in the capillary bed |
| coronary artery | takes blood directly from aorta to heart tissue |
| apex | the pointed end at the inferior end of the heart |
| septum | muscular wall that separates the ventricles |
| blood pressure | force of blood against the walls of the arteries |
| sinoatrial node | the bundle of tissue in the atrium that controls the heartbeat |
| pulse | wave of blood rising and falling in a large artery |
| systolic pressure | first and highest of the two blood pressure readings |
| diastolic pressure | lower blood pressure reading; the second number |
| systole | phase when atria or ventricules are contracting |
| diastole | phase when atria or ventricles are resting |
| vericose veins | winding, bulging veins in the lower extremities of the body |
| atherosclerosis | build up of plaque deposits in the arteries |
| hypertension | medical term for high blood pressure |
| blood | plasma, erytrhocytes, leukocytes, platelets |
| erythrocytes | red blood cells |
| leukocytes | white blood cells in blood |
| lymphocytes | white blood cells usually housed in lymphatic system |
| univeral donor | Type O negative blood |
| Type AB blood | can receive blood from all other types |
| Blood type with both A & B antibodies | Type O blood |
| Blood with B antigens and A antibodies | Type B blood |
| Blood type with B antibodies and A antigens | Type A blood |
| oxygen | carried to body tissues by blood |
| carbon dioxide | carried away from body tissues by blood |
| hemoglobin | chemical in red blood cells that can puick up O and CO2 |
| leukemia | a disease in which one or more types of white blood cells are produced in too great numbers |
| sicke-cell anemia | disease involving the deformation of red blood cells |
| rh positive | has extra protein that body can make antibodies against in other types of blood |
| Blood types: A, B, AB, O | caused by multiple alleles |
| blood type AB | shows that there is incomplete dominance in blood type |
| anemia | result of too little blood or not enough hemoglobin |
| valves | found in veins and lymph vessels, but not arteries |
| fluids between body cells | source of lymph |
| capillaries | smallest vessels in either lymphatic or circulatory systems |
