Question

Name the covering tissue in an animal body.
A. Connective tissue
B. Epithelial tissue
C. Cardiac tissue
D. Nerve tissue

Answer 1

Hint: Tissues can be defined as an arrangement or organization of cells at distinct levels. These tissues are involved in performing certain functions of the body. These tissues can be organised into organs.

Complete answer:
-By definition, a tissue is an aggregation of similar cells that perform highly specific functions. Tissues form specific organs that lead to the formation of organ systems. By the term connective tissue, we mean any tissue that supports, protects, and gives structure to other tissues and organs in the body. They are composed of gel like material, cells, and fibers.
-Examples of connective tissue are bone, cartilage, and blood among many others. Cardiac tissue on the other hand is one of the three types of muscle in our body. It performs highly specialized functions of heart contractions where contraction of heart leads to the pumping of blood to all necessary organs. It is only found in the heart. The nerve tissues are an aggregation of cells in the body that controls the body movements, carrying signals and several other important functions. They are found in the brain. Epithelial tissues are found throughout the body and they cover body surfaces and lines body cavities and organs.

Hence, the correct answer is option (B).

Note: The epithelial cells are involved in a wide variety of functions. Functions include secretion, absorption, protection, excretion, filtration, diffusion and sensory diffusion. Thus they carry out very important functions in the biological systems of all living organisms.
