it makes poo
The arterial system generally has a higher pressure than the venous system, so the answer is the aorta. Pressure is lost when the arteries split into capillaries, which have leaky walls.
True
Yes, blood pressure is highest in the aorta due to the force generated by the heart during systole. It progressively decreases as blood moves through the arterial system, reaching its lowest point in the capillaries where exchange of nutrients and gases occurs.
Yes, the highest in the aorta and larger elastic arties, and decreses as the arteries branch and blood travels farther from the heart.Blood pressure drops significantly in the arterioles and steadily decreses through capillaries, venules, and veins, and drops to zero in the right atrium.
Pressure must move from one area to another, otherwise no flow will occur. In the case of the human heart, pressure pushes blood from the aorta, through arteries, arterioles, capillaries, venuoles, and finally veins, to the vena cavae, where the blood goes back into the heart to be re-oxygenated.
circulatory pressure
Blood pressure is highest at the Aorta. BP progressively decreases as it enters arterioles, capillaries, venules, then increases upon reaching the vena cavae. So basically it's the Aorta, and the Inferior and Superior Vena Cava.
Damage to the aorta can impair blood flow to most of the body. The aorta is expandable, and maintains arterial blood pressure between heartbeats.
The capillaries are so much smaller than the vena cavas and aorta because these large blood transportation systems are under a lot of pressure. For example, when blood is first emerging from the heart it is being pumped out with extreme amounts of pressure, if the aorta was as small as the capillaries, then it would burst under the pressure causing mass amounts of internal bleeding. On the flipside, the capillaries are farther away from the heart, here the pressure is not nearly as great as it is nearer to the heart, therefore the capillaries do not need to be big, they just need to be large enough to transport nutrients from the blood to the organs.
Heart = pumping. Aorta and large Arteries= windkessel function (pressure regulation). Capillaries= exchange. Veins= capacitance.
The pressure in the aorta is greatest during ventricular systole, which is when the heart contracts and pumps blood into the aorta. This creates a surge in pressure that is known as systolic blood pressure.
i think arteries, capillaries, aorta just guessing
