They are RBC's i.e. red blood cells.
Red blood cell
Hemoglobin carries oxygen to the body's tissues. It is found in erythrocytes.
nothing, white blood cells kill bacteria they dont transport nutrients
Red blood cells transport oxygen from the lungs to the rest of the body.
hemoglobin
Red blood cells are highly specialized for oxygen transport. They lack a nucleus and instead, contain many copies of hemoglobin. Red Blood cells move single file through the capillaries
Oxygen is transferred to the cells by our red blood cells which have a special molecule called hemoglobin inside. The hemoglobin molecule binds to the oxygen molecule and the reb blood cells transports the oxygen to wherever it is needed.
The Active transport
Hemoglobin in the blood is what transports oxygen from the lungs or gills to the rest of the body (i.e. the tissues) where it releases the oxygen for cell use. it alo removes carbon dioxide from the system.
== == Sugars and amino acids are taken up by a carrier-mediated transport systems into the small blood vessels in the intestinal walls then transported in the blood into the circulation.
