1
Q

What does tissue repair depend on?

A

Vascularity

2
Q

What type of tissues have the greatest capacity to repair? (2)

A
  1. Epithelial

2. Connective

3
Q

What type of tissues have a limited ability to repair? (2)

A
  1. Muscle

2. Nerve

4
Q

What is slow to repair?

A

Cartilage

5
Q

Why is cartilage slow to repair?

A

Because it is avascular

- no blood flow

6
Q

What are damaged tissues removed by?

A

Phagocytosis

7
Q

What happens after phagocytosis occurs?

A

The surrounding tissue cells divide and fill in the gaps

8
Q

How do scars form?

A

If the gap that needs to be filled by the dividing cells is wide

9
Q

Keloid scars

A

Thick scars that can develop in lower layers of the skin

10
Q

Why are epithelial and connective tissues easy to repair? (2)

A
  1. Vascular

2. Not specific

11
Q

Membrane

A

Are a think sheet like structure found throughout the body

12
Q

What do membranes do?

A

Cover and protect internal and external surfaces and organs

13
Q

What do membranes secrete?

A

Lubricating fluids

14
Q

Why do membranes secrete lubricating fluids?

A

To reduce friction

- allows movement

15
Q

What are 2 major types of membranes in the body?

A
  1. Epithelial tissue membranes

2. Connective tissue membranes

16
Q

What are 3 types of epithelial membranes?

A
  1. Cutaneous
  2. Serous
  3. Mucous
17
Q

What are connective tissue membranes composed of?

A

Largely of various types of connective tissue

18
Q

Are epithelial cells present in connective tissue membranes?

A

No

19
Q

What is the most widespread and diverse tissue in the body?

A

Connective tissue membranes

20
Q

What is an example of cutaneous membranes?

A

The skin

21
Q

What are 2 examples of serous membranes?

A
  1. Parietal

2. Visceral

22
Q

Parietal

A

Membrane that lines the cavities

23
Q

Visceral

A

Membrane that covers the organs

24
Q

What is the primary organ of the integumentary system?

A

Cutaneous membrane

- the skin

25
Q

What percentage does the skin take up in weight?

A

16%

- largest organ

26
Q

What makes up the cutaneous membrane? (2)

A
  1. Superficial layer of epithelial cells

2. Underlying layer of supportive connective tissues
