Which of the following statements best describes the function of the pulmonary arteries or veins?     Pulmonary arteries carry deoxygenated blood from the right ventricle of the heart to the lungs.     Pulmonary arteries carry deoxygenated blood to the right atrium of the heart from the lungs.     Pulmonary veins carry deoxygenated blood from the lungs to the left atrium of the heart.     Pulmonary veins carry oxygenated blood from the lungs to the right atrium of the heart.

If the Mitral Valve failed in a patient, would the blood flow back into the Right Ventricle?    Question 6 options:   Only if the pulmonary semilunar valves also fail   Only if the aortic semilunar valves also fail    No, because the flow would be stopped by the bicuspid valve    No, because blood can only flow forward, never in the reverse direction.

Trace the flow of blood in a linear sequence beginning at the lungs and proceeding to the left heart and back to the lungs:             Lungs to Left heart and back to the  lungs   Group of answer choices pulmonary artery, left atria, left ventricle, aorta, arteries, arterioles, capillaries,                         venuloes, veins, vena cava, right atria/ventricle, pulmonary vein   pulmonary vein, left atria, left ventricle, aorta,  arterioles, arteries, capillaries, venuoles, veins, vena cava, right atria/ventricle, pulmonary artery   pulmonary artery, left atria, left ventricle, aorta, arteries, arterioles, capillaries, veins, venuoles,  vena cava, right atria/ventricle, pulmonary vein   pulmonary vein, left atria, left ventricle, aorta, arteries, arterioles, capillaries,       venuloes, veins, vena cava, right atria/ventricle, pulmonary artery

The Greek anatomist Erasistratus, originally from Ceos, identified the correct function of the right atrioventricular valve of the human heart, which was to prevent backward flow of blood from: the right ventricle to the right atrium the right ventricle to the left ventricle the right ventricle to the left atrium the left ventricle to the right ventricle

Trace the pathway of the flow of blood into and through the human heart and lungs (including all major veins, arteries, chambers, valves)

Why is the pulmonary vein called a vein if it carries oxygenated blood?

Put the following sequence in order: _1_02 diffuses enters the blood and binds to hemoglobin in an RBC RBC enters pulmonary venule RBC crosses bicuspid/mitral valve RBC enters left ventricle, ventricle contracts RBC enters pulmonary vein RBC enters a systemic artery RBC enters a systemic arteriole RBC enters a systemic capillary Oxygen is released and diffuses across capillary into cell for aerobic respiration to occur RBC leaves pulmonary capillary RBC crosses aortic valve RBC enters aorta RBC enters left atrium, atrium contracts

A 56-year-old man is admitted to the coronary care unit (CCU) for an acute inferior wall myocardial infarction. The cardiologist is trying to optimize the oxygen delivery to the myocardial tissue. Supplemental oxygen is provided by the nasal cannula at 3 L/min. which of the following best describes the oxygen- carrying capacity of whole blood? it is only related to respitaroy exchange ratioit is only the amount of O2 dissolved in the blooddependent on the alveolar PO2 onlyit is the sum of the dissolved O2 plus the amount of O2 bound to hemoglobin it is only equal to Oxygen attached with Hb

Blood that leaves the right ventricle is _________ and travels along the _______ to the _______.     oxygenated ; systemic vein ; tissues of the body that need oxygen     deoxygenated ; pulmonary vein ; lungs     oxygenated ; systemic artery ; tissues of the body that need oxygen     deoxygenated ; pulmonary artery ; lungs

Deoxygenated blood is returning to your heart from your head. What is the order of the structures of the heart that the blood will pass through, starting with a major vessel?
