QUESTION

Name the most abundant and widely distributed tissue in the human body.

ANSWER: Connective tissue

EXPLANATION

Connective tissue includes blood, bone, cartilage, tendons, ligaments and areolar (loose) tissue. It is found virtually everywhere in the body — binding, supporting and packing around organs, vessels and nerves — making it the most abundant and widely distributed of the four basic tissue types (the others being epithelial, muscle and nervous tissue).

PRACTICE QUESTIONS

1. Which is the most abundant tissue in the human body?

ANSWER: Connective tissue

2. Name the four basic tissue types.

ANSWER: Epithelial, connective, muscle and nervous tissue

3. Name three types of connective tissue.

ANSWER: Blood, bone and cartilage

4. What is the matrix?

ANSWER: The non-living material between connective tissue cells

5. Which cells make connective tissue fibres?

ANSWER: Fibroblasts

6. Name the main protein fibre of connective tissue.

ANSWER: Collagen

7. Is blood a connective tissue?

ANSWER: Yes

8. What is the function of bone tissue?

ANSWER: Support and protection

9. What is the function of cartilage?

ANSWER: Cushioning and support

10. How do tendons differ from ligaments?

ANSWER: Tendons join muscle to bone; ligaments join bone to bone

11. What is areolar tissue?

ANSWER: Loose connective tissue that packs around organs

12. State two general functions of connective tissue.

ANSWER: Binding and support
