67: The Heart Quizellenjmchenry2019-08-13T09:10:58-04:00 Please sign up for the course before taking this quiz. What do the coronary arteries do?1 Go off the top of the aorta and take blood to the head and arms. Supply the cells of the heart muscle tissue. Take blood to the lungs. Receive blood from the lungs. Where does the blood from the pulmonary arteries go?1 to the lungs into the right atrium into the left atrium to the body What is the name of the membrane bag that surrounds the heart?1 pericardium septum myocardium Which blood vessel looks like a giant arch going over the top of the heart?1 pulmonary artery superior vena cava aorta pulmonary vein What does the word root “brachio” mean?1 arms head blood heart The inside of the heart contains lots of “strings.” What do these strings do?1 They tie the atria to the ventricles. They anchor the valve flaps to the walls of the ventricles. They keep the two sides of the heart together. They help the heart to contract. The contraction of the chambers is what makes the lub dub sound of the heart beat.1 True False Which of these blood vessels brings low-oxygen blood from the body into the heart?1 vena cava aorta pulmonary arteries Another name for the tricuspid valve is the mitral valve.1 True False The definition of a “vein” is that it carries blood that is low in oxygen.1 True False Which chambers have a semilunar valve at the top?1 atria ventricles The heart is actual two separate pumps sitting side by side.1 True False What is the technical term for phase of the cardiac cycle when the chambers are contracting?1 diastole systole The word root “pulmo” is always associated with the lungs.1 True False What does the SA node do?1 Sends out an electrical signal that initiates contraction. Causes the heart rate to speed up when you exercise. Recieves an electrical signal and then transfers it on to the ventricles. 66: Blood vessels 68: The Lungs Back to: 67: The Heart
