What are some observations comparing the schematics of the fish and mammal circulatory systems? (Note: these are simplified schematics that don't show every single route for blood, so focus on the heart and the immediate inflow/outflow around the heart.)

The English physiologist William Harvey made all of the following circulatory discoveries except: both pulmonary and systemic blood pressure comes from pumping of the heart the function of valves in the veins is to direct blood flow back to the heart blood in the arteries is under more pressure than is blood in the veins arterial pressure is greatest during diastole and lowest during systole the function of the vertebrate heart is to pump blood continuously

Describe all the events (steps) that occur during a cardiac cycle for mammals (organisms with a double circulation). Please include in your description all the steps illustrated in slide #16 of the Cardiovascular System PowerPoint presentation (Lectures 5&6), as well as the opening and closing of all heart valves (refer to slide #21), and the signals arising from the SA and AV nodes (shown in slide #25). How does this cycle contribute to metabolic homeostasis for our cells, and what is the purpose of the valves?
The events of the cardiac cycle cause cyclical changes in left ventricular pressure and volume over time. Another way to represent these events is with a pressure-volume loop, as shown below. Drag the labels from the left into the appropriate boxes on the pressure- volume loop to demonstrate your understanding of the cardiac cycle. Aortic valve closure AV valve opening Systolic pressure Isovolumetric relaxation Isovolumetric contraction 120 Diastolic pressure Ventricular filling 80 End-diastolic volume Ventricular ejection 40 AV valve closure End-systolic volume Aortic valve opening 60 120 LV volume (mL) O McGraw-Hill Education Reset LV pressure (mm Hg)
An artificial heart works in closed loop by varying its pumping rate according to changes in signals from the recipient's nervous system. For feedback compensation design it is important to know the heart's open-loop transfer function. To identify this transfer function, an artificial heart is implanted in a calf while the main parts of the original heart are left in place. Then the atrial pumping rate in the original heart is measured while step input changes are effected on the artificial heart. It has been found that. in general, the obtained response closely resembles that of a second-order system. In one such experiment it was found that the step response has a %OS = 30% and a time of first peak 7, 127 sec (Nakamura, 2002). Find the corresponding transfer function. Aside from the corresponding transfer function, determine the following as well: delay time, rise time, settling time and steady state error if input is a step response. CO M
note whether the statements below are consistent with an open or closed circulatory system. The circulating fluid flows in one direction (unidirectionally) through a circulatory loop. The circulating fluid is called hemolymph. Ostia are pores in the heart, important for circulatory function. The circulating fluid is called blood. The circulating fluid remains in vessels as it moves throughout the organism. Is the more efficient type of circulatory system.
Briefly describe the differences among animal circulatory systems. What is an open system versus a closed? What are the anatomical differences among vertebrate hearts?
What are the pros and cons of closed and open circulatorysystems? Consider not only the type of information in Table 25.2
As blood flows from the aorta to the arteries, arterioles, and capillaries and through the venous circulation, it encounters various resistances to flow, which results in pressure drops. Using the table, calculate the resistance for an artery and a capillary. (Note: The viscosity of the blood is 3.5 × 10-3 Pa-s.)
