Verified step by step guidance1
Step 1: Understand the components of blood. Blood consists of two main parts: the liquid portion and the formed elements (cells and cell fragments).
Step 2: Identify the formed elements. These include red blood cells, white blood cells, and platelets, which are suspended in the liquid portion.
Step 3: Differentiate between plasma and serum. Plasma is the liquid portion of blood that contains water, proteins, nutrients, hormones, and waste products. Serum is plasma without the clotting factors.
Step 4: Recognize that hemoglobin is a protein found inside red blood cells, not a liquid portion of blood.
Step 5: Conclude that the liquid portion of blood, which carries the formed elements and various substances, is called plasma.
