Connective Tissue in Biology

Questions and Answers

What is the primary role of connective tissue in relation to epithelial tissue?

To provide structural support and framework (correct)

To cover surfaces and line cavities

To perform the actual functions of the organ

To secrete hormones for regulation

Which of the following substances is chiefly secreted by connective tissue?

Keratin

Collagen and elastin (correct)

Lipids

Glycogen

What distinguishes stroma from parenchyma in tissue organization?

Stroma is the supportive framework, parenchyma consists of functional cells. (correct)

Stroma is involved in cellular metabolism, parenchyma is structural.

Parenchyma provides structural support, stroma consists of active cells.

Parenchyma is always vascularized, while stroma is not.

Study Notes

Types of Tissue

Tissues are groups of cells that work together to perform specific functions.
There are four main types of tissue: epithelial, connective, muscle, and nerve.

Connective Tissue Overview

Connective tissue provides essential support and a framework for organs and other tissues to function effectively.
While epithelial tissue covers and lines body surfaces, connective tissue forms the underlying structure known as stroma.

Roles of Connective Tissue

Connective tissue secretes collagen and elastin, which are vital for forming the extracellular matrix.
Stroma (connective tissue) provides structural support, while parenchyma (epithelial tissue) consists of cells that perform functions.
The relationship between stroma and parenchyma is analogous to the chassis and engine of a car, respectively.

Examples of Connective Tissue

Bone serves as a strong form of connective tissue.
Cartilage, tendon, blood, and fat cells are all classified as connective tissues, contributing to various functions in the body.
Connective tissue plays a critical role in keeping organs connected and stable, preventing them from being displaced by gravity.
