In the cardiovascular dynamics experiment (part 2), if the left flow tube represents the pulmonary veins, what does the left source beaker represent? Sege Select one: O the right atrium O the left atrium O the pulmonary artery O blood coming from the lungs

We are the atrioventricular valves ______ and _______ (select them in alphabetical order)    We are the semilunar valves _______ and _______ (select them in alphabetical order)    We are the receiving chambers of the heart ______ and ______ (select them in alphabetical order)    Word Options for Blanks: (some may not be used, some may be used more than once) aorta aortic valve bicuspid valve coronary sinus inferior vena cava left atrium left ventricle pulmonary arteries pulmonary trunk pulmonary valve pulmonary veins right atrium right ventricle superior vena cava tricuspid valve

Describe the purpose (and advantages) of a double circulation (“2 pump” circulatory system)

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.

8. We discussed fish, amphibian, and mammalian hearts, but didn’t spend much time on reptiles and birds. Please compare and contrast the anatomy of the heart ina) most reptiles (turtles, snakes, lizards) in terms of number of atria, number of ventricles, total number of chambers, and development of the aorta from aortic arches (left, right, or both). Use a table, not text. Also, include a drawing showing the basic template of dorsal aorta, ventral aorta, and six aortic arches, along with drawings showing the modified patterns of aortic arches in a-d above.

What condition(s) does increasing the diameter of the left flow tube simulate in the human heart (A) increasing afterload (B) increasing preload (C) increasing viscosity of the blood (D) increasing the contractility of the ventricles

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

Why does the right ventricle have a bicuspid valve?   a. The low pressure generated by the right ventricle is best suited to bicuspid valve compared with a tricuspid valve b. The high pressure generated by the right ventricle would be better controlled by a bicuspid compared with a tricuspid valve c. Only a short pumping distance to the lungs is required for the bicuspid valve d. The right ventricle does not have a bicuspid valve

Imagine that you are a red blood cell moving through the circulation. After moving into the right atrium, how many heart valveswill you pass through before you first enter the circulation of the lungs? How many heart valves will you pass through beforeentering the circulation of the brain?
