Q

What does the _____ protect…

(1) Pelvis
(2) Ribcage
(3) Skull
(4) Ribcage
(5) Spine

A

(1) Pelvis - Reproductive organs
(2) Ribcage - Heart
(3) Skull - Brain
(4) Ribcage - Lung
(5) Spine - Spinal cord

19
Q

What are joints?

A

Where 2 bones meet

20
Q

Hinge Joints

A
  • the movement of 180°
  • works like a lever
  • contracts and relaxes (muscles) to move the joint

Examples:

  • Elbow
  • Knee
  • Wrist
  • Ankle
21
Q

Ball & Socket Joints

A
  • rotate 360°
  • allowing a lot of flexibility

Examples:

  • Pelvis
  • Shoulder blade
22
Q

Pivot Joint

A
  • rotate 360°
  • has limitations because of muscles

Example:

  • neck bone
  • radius and ulna (forearm)
23
Q

Fixed joints

A
  • puzzle pieces
  • different pieces combined into one

Example:
- skull
-

24
Q

What muscles are the Bicep and triceps?

A

Antagonistic muscles

25
Q

Tendon

A
  • They connect muscle to bone
  • They are stiff
  • If they were stretchy the joint wouldn’t move
  • Tendons have to be tough to hold powerful muscles to strong bones
26
Q

Cartilage

A
  • Made out of Strong & Spongy tissues
  • Formed at the end of the ball & socket, hinge & pivot joint
  • the ends of the bones grind together when you have arthritis
27
Q

Ligament

A
  • Stretchy
  • They connect bone to bone
  • They would snap every time we bend a joint
28
Q

Synovial Fluid

A
  • found between the ends of bones in joints
  • synovial fluid makes the joints smooth and friction-free
  • it is important during exercise because there is a lot of pressure put onto our joints
29
Q

Excretory System

A

Organ: Kidney
Function: Remove waste from your body (urea)

30
Q

Nervous System

A

Organ: Brain + Spinal cord + 5 senses
Functions: Controls how you respond

31
Q

Digestive System

A

Organ: Esophagus + Mouth + Liver + Stomach + Small Intestines + Large Intestines + Anus
Function: breaks nutrients into parts small enough for your body to absorb and use for energy, growth, and cell repair.

32
Q

Circulatory System

A

Organ: Heart
Function: able to transport blood all over the body

33
Q

Respiratory System

A

Organs: Lungs
Functions: To breathe + give oxygen to your body + release carbon dioxide from the body.

34
Q

Muscle System

A

Organ: Muscle
Functions: To move + gives you the strength to move

35
Q

Skeletons System

A

Organ: Bones
Functions: Movement, Support and protection

36
Q

Organelle

A

Components of a cell. Each organelle has a particular function within the cell

37
Q

Organ

A

A group of tissues working together to carry out a particular function

38
Q

Cell

A

Smallest living unit of an organism. Made of organelles

39
Q

Tissues

A

A group of cells of the same type, working together

40
Q

Organ system

A

Made up of many organs all working towards the same purpose

41
Q

Organism

A

This is a living thing. It can either be made up of one cell, or many cell

42
Q
A
  1. Cranium
  2. Ribs
  3. Clavicle
  4. Sternum
  5. Humorous
