The nonliving matrix of the connective tissue through which the blood cells freely flow is known as the extracellular fluid. To arrive at this answer, let's break down the options and analyze each one.
A. Plasma: Plasma is the liquid component of blood, which carries various substances such as nutrients, hormones, and waste products. Although it allows for the transportation of blood cells, it does not represent the nonliving matrix of connective tissue.
C. Intracellular fluid: Intracellular fluid refers to the fluid contained within cells. It plays a crucial role in maintaining cell structure and supporting cellular functions. It is not directly associated with the nonliving matrix of connective tissue.
D. Submucosa: Submucosa is a layer of tissue found beneath the mucous membrane in certain organs, such as the digestive tract. While it serves important functions, such as providing structural support, it is not directly related to the nonliving matrix of connective tissue in which blood cells flow.
The correct answer is B. Extracellular fluid. Connective tissue consists of cells suspended in an extracellular matrix, which functions to support and provide structure to the tissue. In the case of blood, the extracellular fluid acts as the nonliving matrix through which blood cells can freely move. This fluid is primarily composed of plasma, but also contains proteins, electrolytes, and other substances.
In summary, the nonliving matrix of connective tissue through which blood cells freely flow is the extracellular fluid.
