What is the path that blood follows through the body beginning at the heart?

Answer 1

The path of blood from the heart to the kidneys is first from the abdominal aorta the blood enters the kidney through the renal artery. Then the renal artery divides into a number of segmental arteries. The segments arteries divide into lobar artery. The lobar arteries divide into inter-lobar arteries that travel between the renal pyramids. The inter-lobar arteries branch into arcuate arteries that travel between the cortex and medulla. From the arcuate arteries the blood is carried into the nephrons. In the nephron the blood enters through the afferent arteriole and into the glomerulus. The blood leaves the glomerulus by the way of the efferent arteriole, which the blood is carried to the peritubular capillaries, and finally to the vasa recta. When the blood reached the vasa recta that means that it had travelled through the whole nephron.

The blood travels back to the heart through the veins. First through the interlobular vain, then through the arcuate vein, then through the interlobar vain, then through the segmental vain, and finally exists the kidney by the way of renal vein, and into the inferior vena cava.

Answer 2

To answer these questions, you need to do three things:

# Determine how blood travels from the heart to the artery/arteries that supply the organ of interest # Determine how arterial blood travels through the organ of interest and how it reaches the venous side of the organ # Determine how venous blood from the organ returns to the heart

Steps 1 and 3 are relatively straightforward, so I won't answer them with respect to the liver. But blood flow through the liver (step 2) is a bit more difficult, so I'll discuss that here.

Arterial blood reaches the liver through the right and left hepatic arteries. These arteries branch repeatedly to form hepatic arterioles that themselves branch to become capillaries called hepatic sinusoids. The sinusoids empty into central veins which collect and drain into the hepatic veins. Ultimately the hepatic veins drain into the hepatic portal vein.

Dude, go on this site, it shud show yu a pic of a heart. all i no is that the right side (not your left, the pic shud say right atrium, right ventricle...) of the heart hasn't been oxygenated (so its goin to the liver) and the left side (not your left, it shud say left atrium, left ventricle....) has oxygen (came back from the liver and is pumped to the other parts of the body).

Answer 4

The heart pumps blood to the lungs, where it drops off carbon dioxide to be excreted (exhaled), and picks up oxygen. The blood then returns to the left side of the heart, which pumps it out to the rest of the body. The flow of the blood from the heart to the rest of the body and back to the heart is systemic circulation. The heart pumps the now oxygen-rich blood out through the arteries, which are wide, thick-walled blood vessels. Then the blood moves into smaller vessels called capillaries, where it releases the oxygen and nutrients it carries to the body's cells. At the same time, it picks up waste products like carbon dioxide. The blood then flows into the veins, which carry it back to the heart.

Answer 5

From the capillaries the blood flows into venules, then veins, then the superior and inferior vena cava depending if it is arriving from above the heart or below. Both of them empty into the right atrium.

Answer 6

Blood flows to and from the heart thorough veins and arteries.

Answer 7

Hepatic artery is the blood vessel which supplies arterial blood to the liver from the heart.
