Front

What is Epithelial tissue?

Back

A type of tissue that covers body surfaces, lines cavities and organs, and forms glands. It is characterized by closely packed cells with minimal extracellular matrix.

Front

What is the function of the basement membrane in Epithelial tissue?

Back

It anchors epithelial tissue to underlying connective tissue and provides a barrier for the exchange of materials.

Front

Why does Epithelial tissue have little extracellular space between cells?

Back

Epithelial tissue is designed for protection and absorption, requiring cells to be closely packed to form a barrier.

Front

What is the significance of a high rate of cell division in Epithelial tissue?

Back

Epithelial tissue is exposed to wear and tear, so a high rate of cell division allows for quick repair and regeneration.

Front

What adaptations are found in Simple columnar epithelial tissue?

Back

Microvilli and goblet cells, which increase surface area for absorption and secrete mucus, respectively.

Front

What is the main cavity that contains most of the digestive system?

Back

The ventral cavity.

Front

What type of connective tissue are tendons and ligaments?

Back

Dense Connective Tissue, which provides strength and support.

Front

What is the role of melanin in the skin?

Back

Melanin helps protect skin from UV radiation, is responsible for skin color, and is found in almost every human being.

Front

What are the characteristics of connective tissue?

Back

Connective tissue has a diverse range of functions, including support, binding, and protection, and is characterized by a large amount of extracellular matrix.

Front

What is the difference between loose and dense connective tissue?

Back

Loose connective tissue has a more flexible structure with fewer fibers, while dense connective tissue has a higher concentration of collagen fibers, providing strength.
