Red blood cells contain hemoglobin. These cells are also known as erythrocytes.
As the name says, red blood cells are found in the blood. If there is blood there, there is red blood cells.
The body wouldn`t exist because the body needs blood to survive.
Iron is a key component in the production of red blood cells because it is necessary for the formation of hemoglobin, the protein that carries oxygen in the blood. Without adequate iron, the body cannot produce enough hemoglobin, leading to a condition called iron deficiency anemia.
The cells in the bloodstream include red blood cells, white blood cells, and platelets. Red blood cells carry oxygen to tissues, white blood cells help fight infections, and platelets aid in blood clotting.
