Potassium
molecules
Cells receive nourishment from the blood. The blood carries molecules that are broken down from food in the digestive system.
Insulin helps to lower potassium levels in the blood by promoting the movement of potassium from the bloodstream into cells. This can be helpful in treating hyperkalemia, a condition characterized by high levels of potassium in the blood that can be dangerous if left untreated. Insulin is often used in conjunction with other treatments to quickly lower potassium levels in cases of severe hyperkalemia.
Hemoglobin molecules on the surface of the red blood cells.
Red blood cells release oxygen molecules in the capillaries of body tissues where they are needed for cellular respiration. The oxygen diffuses from the red blood cells into the surrounding tissues due to the concentration gradient between the red blood cells and the tissues.
Excess blood potassium (hyperkalemia) is typically removed by increasing the secretion of aldosterone. Aldosterone stimulates the kidneys to increase the secretion of potassium by cells within the kidney nephrons, promoting the excretion of excessive potassium from the body through urine.
Iron is necessary to carry oxygen molecules to your cells.

cells with protein markers do not interact with white blood cells' receptor molecules and are not detected by the immune system.
