HERE IS BLOOD FLOW STEP-BY- STEP THROUGH THE HUMAN HEART:
Oxygen poor blood is collected from the Inferior and Superior Vena Cava. It is released into the Right Atrium where it moves through the Tricuspid Valve into the Right Ventricle. When the Right Ventricle contracts, blood is forced through the pulmonary valve into the pulmonary artery which splits into the Left and Right Pulmonary Veins. Blood is taken via the arteries to the lungs where the oxygen and carbon dioxide diffuse through the simple squamous tissue. Oxygen- Rich blood then returns to the heart via the Pulmonary Trunk which empty into the left atrium. Once the atrium contracts, the blood passes through the Bicuspid Valve into the Left Ventricle. Once the ventricle contracts blood is forced through the Aortic Valve and out of the Aorta to travel to the blood tissue.
If you are looking at this, you are probably taking Biomed..... MY HEART GOES OUT TO YOU! IF I KNEW WHAT BIOMED WOULD BE LIKE< I WOULD HAVE NEVER TAKEN IT! <3

∙ 15y agoThe heart squeezes the blood out (valves keep it from going backwards) into the large arteries. The arteries are elastic (like long, skinny balloons). How much flows out at the other ends depends on how many capillaries are open at any given time. They open and close depending on the (partial) pressure of oxygen locally. the blood flows from there back to the heart via veins.
The pulmonary side is about the same, but all the capillaries are always open and so the working pressure is much lower.
Note that the systemic side controls flow.

What is the function of vena cava?
It brings deoxygenated blood to the heart.Return blood to the heart.
Flow of blood through the hears to the lungs?
The flow of blood from the heart to the lungs and back to the heart is called pulmonary circulation.
To get to the heart what does blood flow through?
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.
Resistance to blood flow through blood vessels is a function of?
capillaries
What direction does the blood flow in the heart?
there are two main veins that makes the blood flow toward the heart which are the superior vena cava and inferior vena cava.
Does deoxygenated blood flow?
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.
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 does blood flow through the veins?
Toward the heart.
What cause the blood to flow through the blood vessels?
The heart is a pump and move blood through the blood vessels.
Does blood flow from your heart through artieries and returns through veins?
Yes, blood flows into the heart via veins. Blood flows away from the heart in aryteries.
