The nonliving matrix of the connective tissue through which the blood cells freely flow is the? A.plasma. B. extracellular fluid. C. intracellular fluid. D. submucosa.
To determine the answer to this question, we need to understand the components of connective tissue and identify the nonliving matrix through which blood cells flow.
Connective tissue is made up of cells and an extracellular matrix. The extracellular matrix is a complex mixture of proteins, fibers, and ground substance that provides structural support to the tissue. In the case of blood, the nonliving matrix is called plasma.
Plasma is the liquid portion of blood that is made up of water, proteins, hormones, electrolytes, and other substances. It acts as the carrier medium for blood cells, allowing them to flow freely within blood vessels.
Therefore, the correct answer to the question is A. plasma.
