front 1 Atria | back 1 The upper chambers which receives which receives blood into heart |
front 2 Ventricles | back 2 which are the lower chambers that pump blood out of the heart. |

front 6 left heart | back 6 carry oxygenated blood are colored blue |
front 7 Right atrium | back 7 receives unoxygenated blood from superior vena cava and inferior vena cava |
front 8 superior vena cava | back 8 collects blood from the upper head and upper body region |
front 9 inferior vena cava | back 9 receives blood from the lower parts of the body |
front 10 The right ventricle | back 10 Receives oxygenated blood from the right atrium |
front 11 The left atrium | back 11 receives oxygenated blood from the lungs to the pulmonary veins |
front 12 Whats the primary function of the right ventricle | back 12 To pump blood through the pulmonary arteries to the lungs. It receives unoxygenated blood from the right atrium. |
front 13 People with chronic high blood pressure | back 13 generally develops left ventricular hypertrophy |
front 14 What happens when the ventricle is forced to over work | back 14 It will eventually enlarge a condition called ventricular hypertrophy |
front 15 why is the left ventricular myocardium thicker then the right myocardium | back 15 Difference is the result is the result of the greater amount of force required of force required to pump blood into the systemic circulation through the aorta |
front 16 why is thickness of the myocardial important | back 16 The thick muscle is needed to create enough force to pump blood . |
front 17 HOw does blood leave the left ventricle | back 17 blood leaves through the aorta , the largest artery of the body |
front 18 Left ventricle | back 18 receives oxygenated blood from the left the primary function of the left ventricle is to pump blood into the systemic circulation |
front 19 Left atrium | back 19 Receives oxygenated oxygenated blood from the lungs through 4 pulmonary veins |
front 20 semilunar valves which are known for the cusp because they resemble half moon | back 20 They control the outflow of blood from the right and left ventricles and are therefore exit valves |
front 21 Av valves | back 21 allow blood to enter the ventricles |
front 22 In the heart blood flows where | back 22 blood flows from the atria through the av valves into the ventricles |
front 23 Two valves are called | back 23 atrioventricular valves which are located between the atria and the ventricles |
front 24 What are the purpose of the heart valves | back 24 To keep the heart valves flowing in one direction |
front 25 How many valves the heart have? | back 25 The heart has four valves |
front 26 the lower ventricles | back 26 Are the pumping chambers |
front 27 The upper atria is what | back 27 They are the receiving chambers |
front 28 What are the large vessels called attached to the heart | back 28 The great vessels which includes superior vena cava inferior vena cava pulmonary trunk,four pulmonary veins and aorta. |
front 29 pulmonary artery hypertension | back 29 developes right ventricular hypertrophy and right heart failure |
front 30 What happens if the blood pressure not lowered what will happen | back 30 The left ventricle will eventually weaken and fail as a pump |
front 31 what is the sa node called | back 31 the pacemaker |
front 32 when is the coronary blood flow the greatest | back 32 during relaxation |
front 33 pulmonary circulation summarized | back 33 The oxygenated blood flows through the four pulmonary veins from the lungs into the left atrium.From the left atrium , the bloods flows through the biscuspid valve into the left ventricle , left ventricular contraction forces blood throught the aortic valve into the aorta for distrubution to systemic circulation.The path way of blood flows through the heart. |
front 34 where do the coronary arteries arise from | back 34 The base of the ascending aorta |
front 35 The blood that nourishes and oxygenate the myocardium | back 35 Is provided by the coronary Arteries |
front 36 abnormal heart sounds | back 36 They are called murmurs |
front 37 What if the valve become leaky in the aorta valve | back 37 It will damage the heart |
front 38 stenotic valve | back 38 make it difficult for a heart chamber to force blood through the stenosed valve their by increasing work of the pumping chamber it can cause heart failure and hypertrophy |
front 39 when valves are narrow | back 39 Its called stenosis |
front 40 semi luna valves | back 40 open and close due to pressure |
front 41 The aortic valve | back 41 opens nd flows into aortic valve snaps closed and prevents back flow from the aorta to the ventricle |
front 42 When the right ventricle contracts | back 42 blood from the ventricles forces pulmonary valve open then flows to the pulmonary trunk which is the large vessel that carries blood from the right ventricle to the right and left pulmonary arteries |
front 43 when the right ventricle relaxes | back 43 the pulmonic valve is closed |
front 44 what are the two exit sv valves | back 44 pulmonic and aortic sv |
front 45 When the left ventricle contracts | back 45 the mitral valve closes and prevents the flow of blood from the left ventricle back into the left atrium |
front 46 what happens when the mitrial valve is open | back 46 blood flows from the left atrium into the left ventricle |
front 47 What is the left av valve called | back 47 The biscuspid valve since it has two cuffs and its also called the mitral valve because it resembles a bishop mitre hat |
front 48 When the right ventricle contracts | back 48 the tricuspid valve will close and prevents blood from flowing back into the right atrium |
front 49 If the tricuspid valve is open | back 49 Blood flows from the right atrium to the right ventricle |
front 50 The right av valve | back 50 Is called the tricuspid valve because it has three cusp |
front 51 chordae attendee attached to papillary muscles in ventricular muscles | back 51 As blood pushes the cusp ino closed position , the papillary muscles contract, pulling on the chordae tendineae |
front 52 chordae tendineae | back 52 fiborous band of tissue |
front 53 closed av valves do what ? | back 53 They prevent backward flow of blood from the ventricles to the atria |
front 54 When the ventricles contract, the heart muscles | back 54 compresses or squeezes the muscles in the ventricles then the blood pushes the cusp upward towards the atria in a closed position |
front 55 What closes av valves | back 55 Presssure!!! |
front 56 What do the semilunar valves do | back 56 They control the outflow of blood from the right ventricle and left ventricles which therefore are exit valves |
front 57 when the ventricles are relaxed | back 57 the cusps hang loosely within ventricles in this position , the valves are open and permit blood flow from atria to ventricles |
