Plasma is the pink surface. White blood cells (leukocytes) are the large, white spots. Red blood cells (erythrocytes) are the round, jelly donut looking shapes. Platelets are the black spots.

Functions:

Erythrocytes-

-Also known as red blood cells.
-They contain hemoglobin so that they are able to carry oxygen to all cells of the body.
Hemoglobin: a protein that binds oxygen in the lungs and releases it in capillary networks through out the body
-They also transport some carbon dioxide to the lungs.

Leukocytes-

-Also known as white blood cells.
-Leukocytes fight infections and diseases.
-Provides body with immunity.
