1. Blood does not have an expiration date. However, blood products such as packed red blood cells, platelets, and plasma have different expiration periods. Packed red blood cells last up to 42 days, platelets last up to 5 days, and plasma can be frozen and stored for up to a year.
2. Signs of old blood can vary depending on the context. In the body, old blood that has been metabolized and broken down may appear dark or brownish in color and have a slightly different odor. In medical settings, signs of old blood can include clots or changes in the consistency and appearance of the blood.
3. In the body, old blood is broken down by the liver and spleen. The breakdown products of old blood, such as bilirubin, are then processed and eliminated through urine and feces.
4. Blood is primarily produced in the bone marrow, which is the soft tissue found inside bones. Specifically, red blood cells, white blood cells, and platelets are produced in the bone marrow.
