How does blood regenerate

How does blood get created? About a month ago, I lost a lot of blood through a bunch of nosebleeds, to the point where on the last day of my sickness I was a lil drowsy all the time and get head rushes super easily. Today I cut my ankle with my skate and lost a lot of blood again.
A. Has my blood "regenerated" since last month? How fast does it work?
B. do I need to eat certain things to regain blood faster?
C. If B is yes, what foods?

Yes, your body generates and regenerates blood constantly. The liquid portion obviously comes from hydration, which is absorbed into your blood stream through your stomach wall. Red blood cells are produced in your spleen and bone marrow, and I think white blood cells are produced there too. As long as you eat a balanced diet, your body will have the nutrition it needs to produce blood cells. An important ingredient is iron, which is what makes blood red. A good food with lots of iron is spinach.

Yes, blood regenerates. The bone marrow in your body produces blood and blood cells on a constant basis. Even if you don't lose a lot of blood, eventually blood cells wear out and die, and bone marrow makes new ones to replace them.

In most people, a regular healthy diet is all you need to make blood. Some people have medical conditions that stop this from working properly- either they don't make enough blood cells, or in some cases not at all. These people need medical treatment to survive in a lot of cases.

Red blood cells originate from the bone marrow. Foods high in folic acid help the production of blood cells and thus, regenerating blood faster.
