Multiple Choice

Marco and Yara are discussing connective tissue and Marco states that blood can't be a connective tissue because it's a liquid. Yara claims that blood is a specialized connective tissue with a fluid ECM. Who is right and why?

Marco because blood doesn't have a ground substance so it can't be connective tissue.

Yara because the viscosity of the ground substance can vary from low to extremely high.

Marco because connective tissue only includes connective tissue proper.

Yara because all liquids found in the body are connective tissue.

Verified step by step guidance

Understand the definition of connective tissue: Connective tissue is one of the four basic types of tissue in the body, characterized by having cells embedded in an extracellular matrix (ECM).

Identify the components of connective tissue: Connective tissue typically consists of cells, fibers, and a ground substance that makes up the ECM. The ground substance can vary in viscosity.

Examine the characteristics of blood: Blood is composed of cells (red blood cells, white blood cells, and platelets) suspended in a liquid ECM known as plasma.

Analyze the role of the ECM in blood: The plasma in blood acts as the ground substance, which is fluid, allowing blood to flow and transport substances throughout the body.

Conclude based on the characteristics of blood: Yara is correct because blood fits the criteria of a connective tissue due to its cells being suspended in a fluid ECM, demonstrating that the viscosity of the ground substance can vary, including being liquid.
