Question

besides oxygen, what do red blood cells carry? waste from the body to the liver and kidneys for removal defeated infections out of the body antibodies to fight infections

Explanation:

Red blood cells (erythrocytes) primarily carry oxygen from the lungs to the body's tissues. Additionally, they transport carbon dioxide (a waste product) from the tissues to the lungs for exhalation, and also carry waste to the liver and kidneys for removal. The second option is incorrect as white blood cells and related mechanisms handle infections, and the third option is incorrect as antibodies are produced by plasma cells (a type of white blood cell), not red blood cells. So the correct option is the first one.

Answer:

A. waste from the body to the liver and kidneys for removal
