Cardiovascular System

atria each of the two upper cavities of the heart from which blood is passed to the ventricles. The right atrium receives deoxygenated blood from the veins of the body; the left atrium receives oxygenated blood from the pulmonary vein.
EKG a test that checks for problems with the electrical activity of your heart.
kidney filters out wastes (urea), extra salts, sugars and water
pulmonary vein a vein carrying oxygenated blood from the lungs to the left atrium of the heart
veins carry deoxygenated look, slightly elastic, thin walls, have valves, low pressure
bones picks up new red blood cells. contain bone marrow inside long ones which make red blood cells
lungs passages into which air is drawn, so that oxygen can pass into the blood and carbon dioxide be removed. pick up oxygen and clean out carbon dioxide
large intestine concerned especially with the resorption of water and the formation of feces. pick up water from digested food.
small intestine lies between the stomach and colon, consists of duodenum, jejunum, and ileum, secretes digestive enzymes, and is the chief site of the absorption of digested nutrients. pick up nutrients from digested food.
homeostasis keeping the internal environment of the body balanced
carotid artery major blood vessels in the neck that supply blood to the brain, neck, and face.
hypertension high blood pressure
heart murmur sounds during your heartbeat cycle — such as whooshing or swishing — made by turbulent blood in or near your heart.
arteries carry blood away from heart
systolic blood pressure when the heart is contracting. It is specifically the maximum arterial pressure during contraction of the left ventricle of the heart
plasma straw colored, non living part of blood, 90% water, helps regulate body temp, contains electrolytes, transports blood cells, products of digestion and hormones throughout the body.
spleen picks up new white blood cells
inferior vena cava vein carrying deoxygenated blood into the heart, from lower part of the body
superior vena cava vein carrying deoxygenated blood into the heart, from upper part of the body
hemoglobin protein that carries oxygen, 250,000 in one RBC
diastolic minimum arterial pressure during relaxation and dilatation of the ventricles of the heart when the ventricles fill with blood.
stem cell an undifferentiated cell of a multicellular organism that is capable of giving rise to indefinitely more cells of the same type, and from which certain other kinds of cell arise by differentiation.
capillaries allows diffusion of materials across capillary, very thin walls
aorta the main artery of the body, supplying oxygenated blood to the circulatory system. In humans it passes over the heart from the left ventricle and runs down in front of the backbone.
liver cleans out worn out blood cells
atherosclerosis a disease of the arteries characterized by the deposition of plaques of fatty material on their inner walls.
erythrocytes red blood cells. shaped like round plates indented in the center, no nucleus
lymphoid denoting the tissue responsible for producing lymphocytes and antibodies
white blood cell fight infections, large in size, have a nucleus, phagocyte
heart disease atherosclerosis and arteriosclerosis, deposits inside arteries, increase blood pressure, increase risk of heart attack
myeloid pertaining to, derived from, or resembling bone marrow.
platelets smallest part of blood, no nucleus, live 2-4 days, involved in clotting of blood
lymphocytes produce antibodies which clump bacterial poisons or bacteria
