What component of blood comprises 41% of its total volume?

Red blood cells make up about 41% of the total volume of blood. This component is crucial as it is responsible for the transport of oxygen from the lungs to the rest of the body and the return of carbon dioxide back to the lungs for exhalation. The presence of hemoglobin within the red blood cells binds to oxygen, allowing these cells to efficiently carry oxygen to the tissues and organs that need it for cellular respiration and energy production.

While plasma constitutes approximately 55% of blood volume, it primarily serves as the液 medium for transporting nutrients, hormones, and waste products. White blood cells, though essential for immune response and defending against infections, represent a much smaller percentage of blood volume, generally around 1%. Platelets, involved in clotting, also form a small fraction of the blood's composition. Understanding the relative volumes and functions of these components is fundamental in both clinical settings and emergency responses for effective patient care.
