Question | Answer |
---|---|
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 |
