ANATOMY

Detailed explanation-1: -The correct option is C Response to stimulus. Some of the functions of epithelial tissue are: Protection from sunlight, bacteria, physical damage. Absorption through the lining of small intestine into the blood.

Detailed explanation-2: -Functions of epithelial tissue are secretion, protection, absorption, transportation and special sensory receptive.

Detailed explanation-3: -Functions of the Epithelium Absorption of substances in the digestive tract lining with distinct modifications. Regulation and excretion of chemicals between the underlying tissues and the body cavity. The secretion of hormones into the blood vascular system.

Detailed explanation-4: -They form the covering of all body surfaces, line body cavities and hollow organs, and are the major tissue in glands. They perform a variety of functions that include protection, secretion, absorption, excretion, filtration, diffusion, and sensory reception.

Detailed explanation-5: -Typically, epithelial contractions enable embryonic systems to change shape during development. Their contractility machinery (actomyosin) is working against high load to achieve dramatic tissue deformation.
