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.
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).

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.
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.
Blood flows to and from the heart thorough veins and arteries.
Hepatic artery is the blood vessel which supplies arterial blood to the liver from the heart.
circulatory system
Beginning with the return of blood to the heart from the systemic circulation, blood enters the right atrium, then the right ventricle, through the pulmonary trunk to the pulmonary arteries and the lungs, through the pulmonary veins, into the left atrium, left ventricle and is then pumped into the aorta.blood enters and exits the heart through the arteries. blood will exit the right atrium through the pulmonary artery and head towards the lungs. once blood is oxygenated by the lungs it will come back to the heart through the coronary artery and enter in the left atrium.
oxygen-poor blood is pumped through the pulmonary arteries to the lungs. gas exchange occurs in the lungs and the oxygenated blood is then returned to the left side of the heart through pulmonary veins
Yes. The difference is as follows- arteries carry oxygenated blood from the heart. Veins carry blood that has been 'de-oxygenated' by the different parts of the body back to the heart to be pumped through the lungs again.
whe blood go's through the heart it get oxganated
The heart is a muscle and it pumps blood to all the body.it pumps the blood in a circlethe heart itself is one. it pumps blood through the body.they contract and pump blood through your body
Blood flows through veins to get to the heart. Arteries are blood vessels for the blood to leave the heart once it has been oxygenated.
blood could not circulate through the body unless it passed through the heart.
The very famous organ that moves blood through blood vessels is the heart.
The heart pushes blood to your body through the arteries. The blood returns through the veins. The large, flexible artery into which the heart pumps is the aorta.
things that could affect the blood flow through the heart
the heart is a double pump The heart pumps deoxigenated blood from the body through the heart and then through the lungs the back to the heart.
Your heart. Your heart pumps and that moves the blood.
