Blood Composition & RBCs

Flashcards covering key vocabulary related to blood composition and the function of red blood cells.

Hematocrit

The percent of blood volume that is made up of erythrocytes (RBCs), approximately 45%.

Erythrocytes

Also known as red blood cells (RBCs), they are responsible for transporting oxygen and carbon dioxide in the blood.

Leukocytes

Plasma

The liquid component of blood, consisting of water, dissolved solutes, and proteins.

Albumin

Fibrinogen

A plasma protein that is a key factor in blood clotting.

Oxyhemoglobin

The form of hemoglobin bound to oxygen; gives blood a ruby red color.

Deoxyhemoglobin

The form of hemoglobin not bound to oxygen; gives blood a dark red color.

Carbaminohemoglobin

The form of hemoglobin that is bound to carbon dioxide, primarily formed in tissues.

Biconcave structure

The shape of erythrocytes, increasing surface area for gas exchange.
