Summary Introduction
To determine: The reason why erythrocytes and platelets are not fully functional cells.
Introduction: The three main types of cellular elements found in the blood are erythrocytes, leukocytes, and platelets. The leukocytes are called white blood cells and are the only functional cells present in the blood circulation.

This condition is called deep-vein thrombosis, or DVT. Given what you know about blood flow in the veins, explain why periodically getting up and moving around in a plane’s cabin during a long flight may lower the risk that a cloth will form.arrow_forward
