Multiple Choice

What is an important difference between mucous membranes and serous membranes?

Serous membranes are found only in the digestive tract, while mucous membranes are found throughout the body.

Mucous membranes are composed of a single layer of cells, while serous membranes have multiple layers.

Mucous membranes line body cavities that open to the exterior, while serous membranes line closed body cavities.

Mucous membranes secrete a watery fluid, whereas serous membranes secrete mucus.

Verified step by step guidance

Understand the basic definitions: Mucous membranes and serous membranes are both types of epithelial membranes that line different parts of the body.

Identify the location and function of mucous membranes: Mucous membranes line body cavities that open to the exterior, such as the respiratory, digestive, and urogenital tracts. They are involved in absorption and secretion.

Identify the location and function of serous membranes: Serous membranes line closed body cavities, such as the thoracic and abdominal cavities. They produce a lubricating serous fluid that reduces friction between organs.

Clarify the secretion differences: Mucous membranes secrete mucus, a thick, protective fluid, while serous membranes secrete a watery serous fluid.

Summarize the key difference: The main distinction is that mucous membranes line cavities open to the exterior and secrete mucus, whereas serous membranes line closed cavities and secrete a watery fluid.
