Question Video: Describing the Function of Connective Tissue Biology

What is the main function of connective tissue?


Video Transcript

What is the main function of connective tissue? (A) To receive information from stimuli and communicate with the spinal cord and brain via electrical impulses. (B) To contract and move parts of the body. (C) To bind, support, and protect structures within the body. Or (D) to provide a protective surface for internal and external tissues.

A tissue is a group of specialized cells that work together to carry out specific functions. There are four major types of tissue: epithelial tissue, connective tissue, muscle tissue, and nervous tissue. Let’s look a bit closer at each of these types of tissue.

Epithelial tissue lines surfaces, like our lungs, intestines, and our inner skin, to protect them. The cells are close together to prevent unwanted substances from getting through.

Connective tissue connects, supports, binds, and protects structures. It is usually made up of living cells and nonliving components. Some examples include bone, blood, and cartilage.

Muscle tissue helps generate movement with contractile proteins. This includes cardiac muscle that allows our heart to beat, smooth muscle, which helps us digest food, and skeletal muscle, which allows us to bend our arms and walk around.

Nervous tissue sends and receives messages throughout the body. This tissue is especially found in the brain but also everywhere else that we can feel and move.

In this question, we are asked about connective tissue. So let’s look through the answer choices to find the best description of connective tissue’s function. (A) describes nervous tissue, (B) describes muscle tissue, and (D) describes epithelial tissue. So the correct answer is (C), which describes the function of connective tissue. The main function of connective tissue is to bind, support, and protect structures within the body.
