Study Notes
Blood Composition
- Blood consists of red blood cells, white blood cells, platelets, and plasma.
- Blood is classified as a tissue.
Red Blood Cells (RBCs)
- RBCs make up nearly half of the blood volume.
- They are also known as erythrocytes.
- Their function is to transport oxygen from the lungs to body tissues.
- RBCs contain hemoglobin, which combines with oxygen to form oxyhemoglobin.
- Once oxygen is delivered to the tissues, oxyhemoglobin splits back into hemoglobin and oxygen.
RBC Adaptation
- RBCs lack a nucleus, creating more space for hemoglobin and oxygen.
- Their shape is a biconcave disc, maximizing surface area for efficient oxygen absorption.
