Answer:
plasma, red blood cells, white blood cells, and platelets.
Explanation:
plasma is the colorless fluid part of blood, lymph, or milk, in which corpuscles or fat globules are suspended. red blood cells have a high concentration of hemoglobin, a protein that binds to oxygen from the lungs and that gives blood its red color. white blood cells are part of the body's immune system. They help the body fight infection and other diseases. platelets are pieces of very large cells in the bone marrow called megakaryocytes. they help form blood clots to slow or stop bleeding and to help wounds heal.
