1

What is the difference between tissue and organs?

A tissue is a group of cells that work together to form a function, while an organ is different types of tissue organized together to perform a task

2

How do organs or organ systems work together?

Physically and or chemically

3

four types of tissue

epithelial, connective, muscle, nervous

4

epithelial

sheet like, covers external surfaces and lines interior areas

5

connective

connects body structures, (loose - holds organs in place, dense or specialized

6

dense irregular

not stretchy, makes up organs like deep skin and kidneys

7

dense regular

orderly rows, elastic,

8

specialized connective tissue

bone (hardened), cartilage (rubbery)

9

main body energy reservoir

adipose

10

fluid transportation medium

blood

11

what does blood contain?

plasma, red blood cells, white blood cells, platelets

12

smooth muscle tissue

13

attach to bone and are responsible for movement

skeletal muscle

14

only found in the heart wall, typically involuntary, contracts as a unit in response to nervous signals

24

muscles contract to press internal fluid against the body walls.

hydrostatic

25

earthworms and sea anemones have this kind of skeleton

hydrostatic

26

a rigid external protective covering the outside of invertebrates like arthropods.

exoskeleton

27

arthropods like the insects, crustaceans, arachnids have this kind of skeleton

exoskeletons

28

consists of internal bones

endoskeleton

29

directly or indirectly connects all the bones of the skeletal system.

the backbone

30

The skeleton of vertebrates has a backbone made up of smaller bones called

vertebrae
