At any given moment where can blood be found in the body?

Blood is primarily found within the cardiovascular system, which includes the heart, arteries, veins, and capillaries. It circulates throughout the body, delivering oxygen and nutrients to tissues while removing waste products. Additionally, small amounts of blood can be found in the lymphatic system and within the bone marrow, where blood cells are produced. In certain conditions, blood may also be present in body cavities or tissues due to injury or disease.
