Deoxygenated blood from the body enters the right atrium. It flows through the tricuspid valve into the right ventricle. Contraction of the ventricle then closes the tricuspid valve and forces open the pulmonary valve. Blood flows into the pulmonary artery. This branches immediately, carrying blood to the right and left lungs. Here the blood gives up carbon dioxide and takes on a fresh supply of oxygen. The capillary beds of the lungs are drained by venules that are the tributaries of the pulmonary veins. Four pulmonary veins, two draining each lung, carry oxygenated blood to the left atrium of the heart From the left atrium, Blood flows through the mitral valve into the left ventricle. Contraction of the ventricle closes the mitral valve and opens the aortic valve at the entrance to the aorta. The first branches from the aorta occur just beyond the aortic valve still within the heart. Two openings lead to the right and left coronary arteries, which supply blood to the heart itself.

∙ 14y agoLet's start at the inferior and superior vena cava. They carry O2 poor blood into the right atrium which then flows to the right ventricle through the tricuspid valve. The right ventricle pumps the blood through the pulmonary semi-lunar valve to the pulmonary artery. It then travels to the lungs so gas exchange can happen and the blood is now O2 rich. It goes back to the heart through the pulmonary vein and into the left atrium. The blood then flows to the left ventricle through the bicuspid valve. Then it goes to the Aorta through the aortic semi-lunar valve and travels to the rest of the body. After the blood is done in the body in goes to the superior and inferior vena cava and it starts all over again.

What does the peak in the blood flow trace represent?
Flow as a result of systolic pressure.
Can you Trace blood flow from kidney to small intestine?
yes
How is it possible to determine the direction of blood flow from the blood spatter?
human
Trace the pathway of a drop of blood from the myocardium of the heart to the arm?
The myocardium does not have blood flow to the arm. The myocardium is the muscle of the heart and therefore only supplies blood to the heart.
How does blood flow through the brain to the heart?
trace blood flow through the kidney from the renal artery to the renal vein? blood flow through kidney from renal artery to the renal vein
How the human heart could compensate for flow rate changes to maintain blood pressure?
The human heart could compensate for flow rate changes to maintain blood pressure by setting the pace at which it beats and maintains blood flow. When a heart rate increases, blood pressure will rise, and when a heart rate decreases, blood pressure will drop.
What part of the eye has highest blood flow of any human tissue?
choroid
How do you trace blood from the left coronary artery to the apex of the heart and back to the right atrium?
A person can trace the blood flow from the left coronary artery to the apex of the heart and to the right atrium, by following inter ventricular artery. Blood also will move through the pulmonary semi lunar valve.
How do you use valve in a sentence?
The human heart has valves to prevent the reversal of the blood flow.
How would you trace the path of blood flow from the femoral artery to the femoral vein?
I believe you would use a tracer chemical and an MRI or CT scanner.
Trace the flow of blood through the nephron?
the flow of blood through the nephron is : enters through the afferent arteriole, then flows through the glomerulus and into the efferent arteriole. Blood then enters the peritubular capillaries and the vasa recta and then flows through the cortex and medulla of the kidneys close to the tubules Answer: so the flow is afferent arteriole, efferent arteriole, peritubular capillaries, vasa recta
How do you trace the flow of blood from the left ventricle to capillary beds?
The blood flows from the left ventricle into elastic arteries (aortic trunk), then to the muscular arteries (external carotid artery), then to arterioles, then to the capillary beds.
