cells making a body

Question 1

first structural level of body

Answer 1

cells

Question 2

second structural level of body

Answer 2

cells with simular specialisations group together to form tissue (nerve cells from nervous tissue)

Question 3

third structural level of body

Answer 3

different types of tissues work together as organs. made up of 2 or more tissues (stomach made with epithelial tissue, muscular tissue)

Question 4

fourth structural level of body

Answer 4

system - group of organs that work together fro a common purpose

Question 5

tissue
- 4 types

Answer 5

group of cells similar ins structure and work together to carry out specific function. 4 main types:
1. epithelial tissue
2. connective tissue
3. muscular tissue
4. nervous tissue

Question 6

epithelial tissue

Answer 6

a covering or lining tissue
- outer layer of skin - heart, kidneys, intestine, liver lungs are lined with ET
- cells are closely joined together, vary in shape from thin and flat to column an cube shaped
- close together =- very smooth surface

Question 7

connective tissue

Answer 7

provides support for the body and holds all parts together
- cells aren’t as close together, separated from each other by matrix
- includes bone, cartilage, tendons, ligaments, fat storage tissue

Question 8

msucular tissue

Answer 8

long, thing and can contract to become shorter, there are 3 types of muscular tissue:
1. skeletal
2. smooth
3. cardiac

Question 9

MT: skeletal muscle

Answer 9

make up muscles that are attached to bones
- voluntary control
- striated

Question 10

MT: smooth muscle

Answer 10

found in walls of stomach, intestines, walls of BV,
- involuntary movement
- not striated

Question 11

MT: cardiac muscle

Answer 11

makes up most of heart
- involuntary

Question 12

nervous tissue

Answer 12

made up of neurons
- when a part of neuronal is stimulated , messages can be passed through these projections from one part of body to other
