An erythrocyte travels through the heart and lungs.  Starting in the inferior vena cava, list in order, all chambers, valves, and vessels an erythrocyte will pass on this incredible journey to the ascending aorta.

During Diastole, pressure inside the ventricle drops to near zero, but pressure inside the aorta only decreases to 80 mmHg. Pressure remains elevated in the aorta because The walls are elastic Blood is flowing so fast Smooth muscles are actively contracting There is resistance to flow

Radial, brachial, femoral, temporal, facial, and common carotid arteries are the ones usually used to measure _____.

Trace the path of a red blood cell from the left ventricle to a capillary in the right lung. Name the heart chambers, valves, major blood vessels that the cell would pass through (in order) as well as describing the order of vessel types it would pass through in the lungs and body locations (if appropriate). If there is an option as to the path, choose whatever path you prefer.

Fill in the blank:  The _______________________ of an artery wall is largely composed of connective tissue.

Which structure(s) (if any) do NOT produce action potentials (APs)?   SA node   Atrial muscle   AV node   Ventricle muscle   These ALL produce APs

If a drop of blood were going from the inferior vena cava to the heart, trace the path of that drop of blood from the vessel (IVC) through the four chambers of the heart, four valves of the heart and the lungs, in the correct sequence, ending with the drop of blood going into the aorta.

The input and exit valves to the ventricles are located in a superior position to the lumen.  What challenges does this create during the cardiac cycle relative to a normal pump where the exit valves would be on the opposite side (inferior) to the input?

Activation of the vascular endothelium is an important event associated with cardiovascular diseases. Explain why. (minimum 60 words)

Describe a path a red blood cell would take once it passed though the aortic semilunar valve and traveled to the brain by the way of a carotid artery and returned to the left ventricle. Include any valves, arteries, veins and chambers along the way.
