Bone marrow manufactures a lot of these.

Explanation:
Bone marrow is where hematopoiesis happens, generating the cells that circulate in blood. It continuously makes both red blood cells and white blood cells in large quantities to replace what is lost and to meet body needs. Red blood cells pool oxygen to tissues and have a relatively fixed lifespan, so their production is enormous. White blood cells, with various subtypes, are produced in large numbers to maintain immune defense and respond to infections. Platelets are also produced here, but the sheer scale of red and white blood cell production best fits the idea of “a lot of these,” making red and white blood cells the most fitting answer.
