Does the water that we drink become blood? If so, how often?

it doesn’t “become blood” rather it acts as a transportation for nutrients and cells to move around your body. your kidney filters a lot of that out from your blood before it exits your body as urine
blood is just what we call the mixture of water and all the other stuff but water mainly serves as a way for all that stuff to circulate around
Blood delivers water to our cells, including the cells in our blood. Water is required by every cell in our body, so it becomes everything all the time. Different cells, like different animals may need water more or less frequently. Not sure how ‘thirsty’ any cells found in the blood are, but water is a 51% of our blood and 70% of our bodies. It is everywhere.
Water is drawn into blood when it enters the small intestines. It joins the blood diluting it. Stuff that makes blood are the cells and proteins floating in it. Most of the water from diet enters the blood unless the person has diarrhea. It is removed by the kidneys to regulate the dilution.
Typically every time you drink water it mostly becomes part of your blood. Later on your kidneys will remove some of it from your blood either because they detect that your blood is too watery, or because they have to take it out to be able to filter out other toxins that you need to get rid of.
If you drank water and it doesn’t go into your blood you’ll know because either you have a very wet stool or you’d be throwing it up. There isn’t anywhere else for the water to go.
If you took out a sample of your blood and separated all the components, one of the biggest components would be plasma. Plasma is about 90% water with the rest of it being proteins, salts, and other junk dissolved in. Red blood cells (RBCs) are what bring nutrients and oxygen to your cells. RBCs are made in your bone marrow. You can imagine your vascular system as a river with a ton of boats on it. The river itself is the plasma and the boats are the RBCs.
Water also exists inside your cells (intracellular fluid), outside your cells in the tissues (extracellular fluid) and tons of other places. The water gets there by diffusing out of your blood vessels.
All of it, all the time. Water that you ingest makes its way through the GI tract, is absorbed across the lining of the intestines, and from there diffuses into surrounding small blood vessels. At that point it’s part of your total blood volume (and all other bodily fluids are in turn derived from blood). Any water that *doesn’t* take this route is going to be coming out the other end of the GI tract.
