The aorta, the largest artery in the body (in diameter), carries oxygen-rich blood away from the heart as it begins the systemic blood flow circuit throughout the body. Owing to the fact that the aorta connects directly to the heart, the blood pressure (BP) inside the aorta is very high. As blood travels further from the heart, the BP gradually decreases. For example, the BP in the aorta is higher than in the brachial artery; the BP in the brachial artery is greater than in the antecubital artery; the BP in the antecubital artery is greater than in the radial artery. Based on the understanding that walls of the aorta are subjected to extreme outward pressure, hypothesize the order of specific tissue types one would expect to find in the aorta (from deep to superficial) and explain your rationale

Blood flows from the heart (specifically, the left ventricle) into the aorta to feed the rest of the body oxygen. As blood flow moves from the ascending aorta and downward to the abdominal aorta, some of the volume is directed through a branching network. As the blood reaches the pelvic region, there is a bifurcation, as shown in figure, into the left and right common iliac arteries. This bifurcation is symmetrical but the common iliac vessels are not the same diameter. Given that the kinematic viscosity of blood is 4 cSt (centistokes), the abdominal aorta’s diameter is 15 mm, the right common iliac artery’s diameter is 10 mm, and the left common iliac artery’s diameter is 8 mm, determine the mean flow rate through the right common iliac artery if the abdominal aorta’s mean velocity is 30 cm/s and the left common iliac artery’s mean velocity is 40 cm/s.
As blood goes from the left ventricle through the arteries and veins of the human body, both its speed and pressure change. The arteries and arterioles can either constrict, reducing the area, or dilate, increasing the area, in response to certain conditions. Both of these changes can affect blood flow and blood pressure. An artery can also develop a permanent narrow area (stenosis) or a permanent wide area (aneurysm). Both of these changes can have significant health consequences. Suppose that in response to some stimulus a small blood vessel narrows to 90% of its original diameter. If there is no change in the pressure across the vessel, what is the ratio of the new volume flow rate to the original flow rate?A. 0.66 B. 0.73 C. 0.81 D. 0.90
Blood is pushed out of the heart through a large vessel, called the aorta. The aorta then divides into smaller and smaller blood vessels, eventually reaching vessels called capillaries. Capillaries are so small that oxygen and nutrients can diffuse across the vessel walls and into the tissues of the body, with CO2 and waste diffusing back into the blood. Let's say that the cross-sectional area of the aorta is 1 cm2 = 100 mm2. The blood pumps through the aorta at 100 mm/s but only through the capillaries at 1 mm/s. If each capillary has a cross-sectional area of 20 mm2, how many capillaries must there be in the body? Note: these numbers are not physiologically correct, but were chosen to make the math easier. The blood velocity through the aorta is closer to 300 mm/s. The capillaries have a total cross-sectional area of ~600,000 mm2 (6000 cm2), with a blood flow rate closer to 0.2 mm/s.
Which of the following is the correct sequence of blood flow through pulmonary circulation? Group of answer choices Right atrium → right ventricle → pulmonary arteries → pulmonary capillaries (in lungs) → pulmonary veins → left atrium Left atrium → left ventricle → pulmonary arteries → pulmonary capillaries (in lungs) → pulmonary veins → right atrium Right atrium → right ventricle → pulmonary capillaries (in lungs) → pulmonary arteries → pulmonary veins → left atrium Left atrium → left ventricle → pulmonary capillaries (in lungs) → pulmonary arteries → pulmonary veins → right atrium Left atrium → left ventricle → pulmonary veins → pulmonary arteries → pulmonary capillaries (in lungs) → right atrium
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…
Atrial fibrillation (AF) is a rapid and unorganized beating of the upper chambers of the heart. It is generally not life-threatening in the short term, but it dramatically impacts how a patient feels, and it can have bad consequences in the long term. One of those “bad consequences” is stroke, caused by blood clots that can form in the atria when they are “fibrillating” for long periods of time, and the clots subsequently flow to the brain. We are now planning a study to see whether a new therapy (perhaps cryoablation plus a new drug) is better than a control therapy (perhaps cryotherapy plus an old drug) at preventing stroke or death. Our primary endpoint will be a composite of stroke or all-cause mortality, and we will structure this as a time-to-event analysis. We think the new therapy will lead to a reduction in risk of 40% (that is, a hazard ratio of 0.60). How many events must we observe (combined across both therapy groups) in order to have 95% power to detect a reduction…
When the alary muscles contract, the hemolymph is forced through the aorta into the head. Upon relaxation, the hemolymph enters the heart through the ostia. Once the hemolymph leaves the aorta, it fills the perineural and perivisceral sinuses, bathing the internal organs at the same time. Present your understanding of this concept through a diagram in the activity worksheet.
Fill in the table below by indicating the organ, region or vessel that the named vessel receives blood from, and the organ, region or vessel to which it delivers blood (see example for aorta and coronary arteries). If you’re doing it right, both columns will have the same answer. You will need to refer to the images in your textbook and lab models to do this.

The lowest velocity of blood flow occurs in the capillaries. True As blood flows from the aorta through the other vessels, blood pressure increases. True Blood flow is at its highest velocity in the venae cavae. True Blood flows from an area of low pressure to an area of high pressure. False Blood flowing from one aorta into billions of capillaries decreases the velocity and pressure of the blood flow. True Blood flow velocity is inversely related to cross-sectional area. True
Hemodynamics are the dynamics of blood flow. Can the Bernoulli's equation be used to study hemodynamics in the cardiovascular system? Why or why not? You should discuss all four of the assumptions of Bernoulli's equation when answering this question.

A heartbeat starts when autorhythmic cells in the 1 [ Select ] (located in the right atrium) create an action potential (electric signal). From there, the signal passes along the internodal pathway to the 2 [ Select] causing the atria to contract. After a slight pause, the signal travels to the 3 [ Select ] , which divides into left and right bundle branches and carries the signal down through the 4 [ Select ] to the apex of the heart. At that point, specialized 5 [ Select ] carry the signal to individual cardiac muscle cells and the 6 [ Select ] contract.
A stent is a device that is implanted into an occluded artery to permit increased blood flow. A permanent, yet flexible, device is needed for use as a vascular stent.
