Verified step by step guidance

Step 1: Begin by understanding the components of blood. Blood is composed of two main parts: plasma (the liquid portion) and formed elements (cells such as red blood cells, white blood cells, and platelets).

Step 2: Recognize that plasma is the fluid portion of blood that contains water, proteins, nutrients, hormones, and waste products. Formed elements are suspended within this plasma.

Step 3: Differentiate between the terms provided in the question. Serum is plasma without clotting factors, lymph is a fluid found in the lymphatic system, and interstitial fluid is the fluid that surrounds cells in tissues.

Step 4: Understand that the combination of plasma and formed elements is specifically referred to as 'blood,' which is the correct answer to the question.

Step 5: Review the definitions of the other terms to solidify your understanding: Serum is derived from plasma, lymph is part of the immune system, and interstitial fluid is involved in nutrient and waste exchange at the cellular level.
