Your heart is a single organ, but it acts as a double pump in the human body explain this important concept (150 words).
Step by step
Solved in 3 steps
- A heart beats 72 times per minute with a total of 10mL of blood pumped with each contraction. What is the cardiac output of the given heart?Why is the left ventricle more muscular than the right ventricle (in heart)? Please write very detailed (at least 300 words) explanation. ThanksYour heart is a single organ, but it acts as a double pump in the human body explain this important concept
- The ventricular walls of the human heart are more muscular as compared to the atrial walls. Why do cardiac muscles have a slow onset of contraction and prolonged contraction?Based on the Image below make a simple explanation (be unique, you can present it through diagrams or shapes) about the flow of blood into and from the heart.why is the heart referred to "two pumps in one"
- Upload a drawing that shows the path of blood as a single circuit (like a loop) from the left ventricle back to the left ventricle. In your drawing you should "split" the heart into separate pumps. Include the atria, arteries, and tissues in your drawing.Describe the conduction pathway of the heart, and discuss two examples of disease states where conduction is altered. I need write 500 word answers on this topic so can you help me to find good sourecs.We analyzed the difference between the action potential of a cardiac contractile cell and an action potential in a neuron. Describe the physiological mechanisms behind the primary difference in the shape of these two action potentials. Why is this feature important to the normal workings of the heart?
- The aorta is the principal blood vessel through which blood leaves the heart in order to circulate around the body. (a) Calculate the average speed of the blood in the aorta if the flow rate is 5.0 L/min. The aorta has a radius of 10 mm. (b) Blood also flows through smaller blood vessels known as capillaries. When the rate of blood flow in the aorta is 5.0 L/min, the speed of blood in the capillaries is about 0.33 mm/s. Given that the average diameter of a capillary is 8.0 μm (1 μm = 1 X 10 –6 m), calculate the number of capillaries in the blood circulatory system.The pressure in the aorta changes throughout the cardiac cycle. During systole, as the heart contracts, the outflux of blood into the aorta causes an increase in pressure, whereas during diastole the pressure decreases as the heart relaxes. A simple model for the aortic pressure waveform is given by the Windkessel effect described by the image below. In this model, the heart is considered a pressure generating pump which is directly connected to an elastic compartment (the aorta), which in turn is connected to a rigid set of peripheral vessels (the hose of the firefighter). 5 Pump Heart Air Windkessel Elastic arteries In order to find the aortic pressure waveform from the Windkessel model, a mass balance formulation around the aorta must be formulated. Coming into the aorta from the heart we have the flowrate Q(t). According to conservation of mass, this inflow rate Q(t) must be equal to the outflow rate into the peripheral vessels and the change in volume of the aorta. To find these…In the calculation of the heart rate using the number 300 method in the ECG, where did the number 300 come from? Why exactly was this method adopted?
