Tissues of the Body

Question 1

This type of tissue is found in the lungs and blood vessels where diffusion must happen quickly

Answer 1

simple squamous

Question 2

Ground substance can take on these main 3 types of consistency

Answer 2

fluid, gelatinous, hard (calcified)

Question 3

This is how epithelial tissue is classified

Answer 3

according to # of cell layers and cell shape

Question 4

These are the four types of tissue in our body

Answer 4

epithelial, connective, nervous, muscle

Question 5

This epithelial tissue has many layers, but the cells at the top are rounded, yet can become squamous

Answer 5

transitional

Question 6

This connective tissue is avascular and has no nerves

Answer 6

cartilage

Question 7

The epithelial tissue found in the small intestine where absorption of nutrients must take place is

Answer 7

non-ciliated simple columnar (no cilia, instead there is microvilli)

Question 8

The 5 types of connective tissue are

Answer 8

loose, dense, cartilage, blood and bone

Question 9

What are tissues?

Answer 9

collections of similar cells that work together for a specialized function

Question 10

The two main types of epithelial tissue are…

Answer 10

covering and lining and glandular

Question 11

Why is epithelial tissue subject to disease

Answer 11

it covers and lines the body leaving it susceptible to wear and tear and thus it is always renewing to make more cells (mitosis). Cancer happens when this division is not controlled.

Question 12

Simple columnar ciliated would be found in what two places in your body?

Answer 12

fallopian tubes, respiratory tract

Question 13

Where would transitional epithelial tissue be found?

Answer 13

the bladder and uterus, areas that require stretching

Question 14

Which tissue is this?

Answer 14

cartilage

Question 15

Which tissue is this?

Answer 15

Adipose (fat)

Question 16

What is the job of a mast cell?

Answer 16

it produces heparin and histamin.

Question 17

What does heparin do?

Answer 17

it prevents your blood from clotting (anticoagulant)

Question 18

What is the job of histamine

Answer 18

causes allergic symtoms of inflammation and constrictionof smoooth muscle

Question 19

What is the difference between the cells in epithelial tissue and connective tissue?

Answer 19

ET cells are closely packed and CT cells are not!

Question 20

What are the 5 general characteristics of epithelial tissue?

Answer 20

1. closely packed cells
2. avascular
3. nerve supply
4. 3 surfaces: apical (top), lateral (side), basal (bottom)
5. high capacity for renewal

Question 21

What epithelial tissue is found in the kidney tubules

Answer 21

siimple cuboidal

Question 22

Where would you find statified squamous epithelial tissue?

Answer 22

the skin, the vagina, the mouth (areas that need protection)

Question 23

What are some functions of epithelial tissue?

Answer 23

diffusion, osmosis, filtration, secretion, absorption, protection, controlling permeability

Question 24

What are some characterisics of connective tissue?

Answer 24

1. not found on surfaces
2. vascular except for cartilage
3. nerve supply except for cartilage
4. fibrous
5. 2 basic elements: cells and extracellular matrix

Question 25

What is the job of a plasma cells?

Answer 25

to secrete antibodies to help fight off infections

Question 26

What is the job of a macrophage?

Answer 26

These are the “big” cell eaters. They engulf foreign substances and dead cells

Question 27

What type of tissue stores calcium, red marrow and yellow marrow?

Answer 27

bone connective tissue

Question 28

The type of connective tissue found underneath the skin is

Answer 28

Areolar (loose)

Question 29

Which epithelial tissue has nuclei at all different levels and has cilia at the apical layer

Answer 29

pseudostratified

Question 30

The cell responsible for production and maintenance of fibers and ground substance

Answer 30

Fibroblast
