Erythrocytes are the most abundant of blood cells, accounting for approximately 99% of all blood cells. They are biconcave disc-shaped cells that lack a nucleus. Erythrocytes have a globulin protein called hemoglobin on their surface for oxygen to bind to.
The blood is the mobile component of the circulatory system. Blood is bright red when oxygenated and dark red/purple when deoxygenated. Blood consists of a cellular element suspended in a liquid called plasma.
Arteries carry blood away from the heart. They have thick walls and a narrow lumen, to resist the high pressure from the blood being forced out of the heart. As the arteries travel toward the more peripheral tissues, they begin a process of segmentation, decreasing in diameter and wall thickness with each division.

Veins are formed with the union of muscular venules. In comparison to arteries, veins have a relatively thin wall and a larger lumen.
