Where does the blood from the pulmonary arteries go?1 into the left atrium to the lungs to the body into the right atrium Another name for the tricuspid valve is the mitral valve.1 True False What do the coronary arteries do?1 Receive blood from the lungs. Supply the cells of the heart muscle tissue. Take blood to the lungs. Go off the top of the aorta and take blood to the head and arms. 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 help the heart to contract. They keep the two sides of the heart together. The word root “pulmo” is always associated with the lungs.1 True False What does the word root “brachio” mean?1 heart blood head arms The heart is actual two separate pumps sitting side by side.1 True False Which chambers have a semilunar valve at the top?1 ventricles atria Which of these blood vessels brings low-oxygen blood from the body into the heart?1 pulmonary arteries vena cava aorta What is the name of the membrane bag that surrounds the heart?1 myocardium septum pericardium Which blood vessel looks like a giant arch going over the top of the heart?1 superior vena cava pulmonary vein pulmonary artery aorta What is the technical term for phase of the cardiac cycle when the chambers are contracting?1 diastole systole The contraction of the chambers is what makes the lub dub sound of the heart beat.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. The definition of a “vein” is that it carries blood that is low in oxygen.1 True False 66: Blood vessels 68: The Lungs Back to: 67: The Heart
