Name________________Per._____Date__________ Circulatory/Respiratory System Study Guide Use your notes, packet and textbook as a reference. Write and know the definitions of the following words: white blood cells – help body fight infection plasma – 60% of blood, fluid that contains many proteins hemoglobin – an iron containing protein that makes up most of the red blood cells cardiac – having to do with the heart vein – blood vessels that carry blood back to the heart aorta – largest artery in the body – takes oxygenated blood into the body pacemaker- cells in the right atrium that sends out signals to make the heart beat. valves – a flap of tissue in the heart (trap door) that prevents blood from flowing backwards platelet –assists in blood clotting – part of blood artery – a blood vessel that carries blood away from the heart alveoli – thin walled air sacs located in the lungs epiglottis – flap that keeps food and saliva out of the trachea diaphragm – muscle that causes your chest to expand when you breathe lung – main organ of the respiratory system nose - warms, moistens and filters air coming into the respiratory system trachea – windpipe, tube that carries air into the lungs oxygen & carbon dioxide (as it relates to the 2 systems) respiratory system – supplies the body with oxygen cilia – bristly hairs that clean dirt capillaries – blood vessels that connect veins to arteries pulmonary –having to do with lungs septum – muscle in heart separating two pumps tissues are made of? tissues are made up of cells Write and know the following about the heart: How many pumps and chambers? 2 pumps and 4 chambers The flow of the blood through the heart: oxygen poor blood enters the rt. atrium, pumped into the rt. ventricle, into the lungs to get oxygen, into the left atrium, into the left ventricle and pumped to the aorta to be circulated thru the body. Location and parts of the heart (packet pg. 29) List the 4 valves and 4 chambers (packet pgs. 29) chambers: rt. atrium, left artrium, rt. ventricle, left ventricle valves: tricuspid valve, mitral valve, aortic valve, pulmonary valve Draw and label a diagram below showing the flow of blood through the valves, chambers, & lungs. Use packet as a reference. Draw and label a diagram below showing the major organs of the Respiratory system: Use packet pgs. 6 & 17 as a reference. (trachea, lungs, epiglottis, alveoli, diaphragm)
