Where does blood go. cuz your heart’s always pumping right? And makeing new blood. so where does it go how does it not just keep building infinitely. like there’s nowhere for it to go cuz your not bleeding so it’s all stuck in your body. so how does it I guess disappear. cuz when I think about it if it’s not exiting the body some how then it should just keep building in your body infinitely so kinda morbid but why don’t you explode from having infinite liquid pumped into your body
Short of it I guess is how does you body not explode from haveing constant liquid pumped into you. and where does it go or does it just disappear? I tried to Google it but I guess I couldn’t word it properly

The red blood cells have a finite lifespan and are filtered out of circulation by the spleen. A large percentage of blood volume is water which is balanced in your body by the kidneys. You pee out excess fluid volume.
The heart doesn’t make new blood every time it pumps. The heart doesn’t make blood at all, that’s mostly your bone marrow. The heart is a pump, it just keeps the blood cycling around your body (which returns to the heart to get pumped around again). You’re not constantly pumping new fluid in, you’re pumping the fluid around a circular system, the fluid itself is replaced more slowly (for example it takes 1-2 days to fully replenish after donating plasma)
Dead blood cells are removed by the body, primarily in the spleen and liver for red blood cells. They get broken down and the parts are either reused or excreted
Think of it like a water fountain, the pump works to bring the water to the hard to reach places and then it falls back down to the resoivoir and cycles.
Your circulatory system is just that a circular flow of pumping blood to different parts of your body and then back to the heart again.
The blood does stop when it hits its destination
The heart does not make blood. New blood cells are produced in your bone marrow.
Most of the cells are red blood cells, made to replace the ones that die — a red blood cell only lives for a few months and then gets recycled by your body. Other cells in your blood are platelets and immune cells. Platelets get used up regularly to patch small holes in blood vessels before they become a problem. Immune cells come in a large number of types and functions, and can live for longer or shorter times depending on what type they are. They get used up fighting off bacteria and viruses and generally cleaning up any unwanted or dangerous cells inside your body.
The liquid comes from drinking water and also contains other nutrients that you get by eating & drinking, as well as assorted chemicals emitted by various parts of your body to pass messages around. The chemicals and nutrients get absorbed by various cells, and leftovers & other waste as well as water are filtered out by your kidneys and emitted as urine.
You excrete waste, including cells that have died.
In the same way you slough off old skin cells, you shed other cells too. What isn’t consumed by macrphages and other specialized cells is eliminated when you urinate or defecate.
There are a few things to consider with your question:
The heart doesn’t make new blood. The heart is pumping to move your blood across your body to distribute nutrients and pick up waste.
The blood is mostly water. The water is extracted through pee and sweat and is replenished when you drink.
The rest of the blood is made up of cells (red, white, etc.) those cells are broken up when they die and their constituents are extracted with the rest of your waste, and new cells are created as needed.
So you never just fill up with blood. It’s always getting recycled.
It’s pumped around, it goes in, is pumped to the lungs, comes back in and is pumped through the body.
You do make and lose blood, but that’s not because of the heart. Blood cells (like all cells) die after a certain time and need to be replaced (since red blood cells don’t have DNA, they can’t duplicate and have to be made in the bone marrow). The dead blood cells are mostly broken down in the liver and everything that isn’t reused is excreted into the intestine after which it goes through the anus.
Your blood goes in a big circle. That’s why it’s called the circulatory system. Your heart pumps it through your lungs where it gets loaded with oxygen. Then it goes through your arteries to deliver the oxygen (and other stuff) to your muscles and organs. Then it travels through your veins to return to your lungs to do it all over again. Each trip takes about one minute!
So the blood doesn’t go anywhere, it keeps circulating around your body.
Of course the things in your blood (red cells, white cells, etc) don’t live forever – they have a finite lifespan. Red blood cells, for example, have an avg lifespan of 3-4 months. When they get too old, they get filtered out of your blood by the spleen and liver, and most of it is actually recycled and reused by your body to create new red blood cells in your bone marrow. The unused junk forms a substance called bilirubin and you poop it out.
