The tissues that cover external and internal body surfaces are

1. epithelial.
2. connective.
3. muscle.
4. nervous.

Summary Introduction

Introduction:

A group of the same type of cells that perform a common function is termed as tissue. Tissues are specific in function. There are four types of tissues in the human body: epithelial tissue, connective tissue, muscle tissue, and nervous tissue.

Answer to Problem 1PL

Correct answer:

The correct answer is option (a) epithelial.

Explanation of Solution

Explanation/justification for the correct answer:

Option (a) epithelial. The epithelial tissue covers the outer surface of organs and blood vessels across the body, and it also covers the cavities of various internal organs. So, the correct answer is option (a).

Explanation for incorrect answer:

Option (b) connective. The connective tissue provides protection and support to many body parts. It also interconnects different organs. So, this is an incorrect option.

Option (c) muscle. The muscle tissue is soft and provides the ability of contraction to the muscles. As a result, it generates muscular movement in the body. So, this is an incorrect answer.

Option (d) nervous. The nervous tissue constitutes the central nervous system and the peripheral nervous system. It transmits signals for internal communication. So, this is an incorrect answer.
