Blood is made of three components: red blood cells plasma, and white blood cells/platelets. One is approximately 55% one is approximately 44% and the other is approximately 1% of blood volume. Whichvalue belongs to which component? Plasma: 55% Red Blood Cells: 44% Platelets/WBCs:1% - Plasma: 55% Red Blood Cells: 1% Platelets/WBCs: 44% Plasma: 1% - Red Blood Cells: 55% Platelets/WBCs: 44% Plasma: 44% Red Blood Cells: 55% - Platelets/WBCs: 1% Multiple Choice 1 point

The correct answer is:<br /><br />Plasma: $55\%$<br />Red Blood Cells: $44\%$<br />Platelets/WBCs: $1\%$<br /><br />Explanation:<br />Blood is composed of three main components: plasma, red blood cells (RBCs), and white blood cells/platelets. The approximate percentages of these components in blood are as follows:<br /><br />1. Plasma: Plasma is the liquid component of blood and makes up approximately $55\%$ of the total blood volume. It is a yellowish fluid that carries nutrients, hormones, and waste products throughout the body.<br /><br />2. Red Blood Cells (RBCs): RBCs are responsible for carrying oxygen from the lungs to the rest of the body and returning carbon dioxide from the body to the lungs for exhalation. RBCs make up approximately $44\%$ of the total blood volume.<br /><br />3. Platelets/WBCs: Platelets are small cell fragments that play a crucial role in blood clotting, while white blood cells (WBCs) are part of the immune system and help fight infections. Together, platelets and WBCs make up approximately $1\%$ of the total blood volume.<br /><br />Therefore, the correct answer is that plasma makes up $55\%$, RBCs make up $44\%$, and platelets/WBCs make up $1\%$ of the total blood volume.
