Question

which of the following is one primary function of epithelial cells? 1 point immunity secretion structural support transmit electrical signals all epithelial cells attach to an underlying structure called the: 1 point squamous layer glandular tissue basement membrane adipose fat

Explanation:

• First question: Epithelial cells have functions like protection, absorption, secretion (e.g., goblet cells in the intestine secrete mucus). Immunity is mainly related to immune cells (like lymphocytes), structural support is a function of connective tissue (e.g., bone, cartilage), and transmitting electrical signals is a function of nervous tissue (neurons).
• Second question: Epithelial cells attach to the basement membrane. Squamous is a shape of epithelial cells, glandular tissue is a type of epithelial tissue that has a secretory function, and adipose fat is a type of connective tissue.

Answer:

• First question: secretion
• Second question: basement membrane
