Mucous Membrane Quiz

What are the three layers of the mucous membrane?

• Skin, Bone, Cartilage

• Epithelium, Lamina propria, Muscularis mucosae

• Nerve, Blood, Lymph

• Artery, Vein, Capillary

Describe the cellular composition of the mucous membrane.

• Red blood cells, white blood cells, and platelets

• Epithelial cells, goblet cells, and immune cells

• Neurons, astrocytes, and oligodendrocytes

• Fibroblasts, adipocytes, and chondrocytes

Explain the role of goblet cells in the mucous membrane.

• Goblet cells secrete acid to break down food in the mucous membrane.

• Goblet cells release hormones to regulate blood flow in the mucous membrane.

• Goblet cells produce enzymes to aid in digestion in the mucous membrane.

• Goblet cells secrete mucus to protect and lubricate the mucous membrane.

What are the main functions of the mucous membrane?

• The main functions of the mucous membrane are to absorb nutrients, regulate body temperature, and produce hormones.

• The main functions of the mucous membrane are to protect, lubricate, and provide a barrier against infection.

• The main functions of the mucous membrane are to support the skeletal system, aid in digestion, and store energy.

• The main functions of the mucous membrane are to transmit nerve signals, regulate blood pressure, and filter waste products.

How does the mucous membrane protect the body from pathogens?

• It has no effect on pathogens

• It attracts pathogens to the body

• It acts as a physical barrier and produces mucus to trap and remove pathogens.

• It weakens the immune system

Discuss the role of mucous membrane in maintaining moisture in the body.

• It absorbs excess moisture from the body

• It secretes oil to keep the tissues dry

• It has no role in maintaining moisture in the body

• It produces mucus to act as a protective barrier and keep the tissues moist.

How does the mucous membrane in the respiratory system help in filtering air?

• Acting as a barrier to prevent air from entering the lungs

• Releasing harmful toxins into the respiratory system

• Causing inflammation and irritation in the airways

• Trapping dust, bacteria, and other particles

Explain the function of mucous membrane in the digestive system.

• Absorption of nutrients

• Regulation of blood sugar levels

• Production of bile

• Protection from stomach acid and digestive enzymes

What is the role of mucous membrane in nutrient absorption in the digestive system?

• Provides a barrier to prevent nutrient absorption

• Provides a large surface area for the absorption of nutrients

• Has no role in nutrient absorption

• Secretes enzymes for nutrient absorption

Describe the protective function of mucous membrane in the digestive system.

• Protection from digestive enzymes, acids, and mechanical damage

• Absorption of nutrients

• Regulation of blood sugar levels

• Protection from UV radiation
