2)There is a type of muscle tissue that can divide and regenerate after an injury. Which of the following functions are performed by that muscle tissue?*(multiple answer)
□Guards entrances and exits to the digestive tracts.
□Moves urine and reproductive tract secretions.
□Maintains blood pressure.
□Regulates diameter of blood vessels.​

Answer 1

Answer (Q1):

The correct statements about cartilage are:

□ Matrix of cartilage contains chondroitin sulfates.

□ Produces antiangiogenesis factor.

□ One third of the matrix is dominated by collagen fibres.

Explanation (Q1):

Cartilage is not vascular, which means it does not contain blood vessels. This is why it is often slow to heal. The matrix of cartilage does indeed contain chondroitin sulfates, which are complex carbohydrates that help give cartilage its elasticity and compressive resistance. Cartilage tissue does produce antiangiogenesis factor, which helps prevent the growth of blood vessels into the cartilage. And yes, collagen fibers make up a significant portion of the matrix, providing strength and resilience to the tissue.

Answer (Q2):

The muscle tissue type that can divide and regenerate after an injury is smooth muscle tissue. It performs the following functions:

□ Guards entrances and exits to the digestive tracts.

□ Moves urine and reproductive tract secretions.

□ Maintains blood pressure.

□ Regulates diameter of blood vessels.

Explanation (Q2):

Smooth muscle tissue is found in the walls of hollow organs like the intestines, stomach, urinary bladder, uterus, and blood vessels. It performs a variety of functions, including moving substances through the body, regulating the flow of blood by altering the diameter of blood vessels, and controlling the passage of materials through the digestive tract.
