Skeletal system lesson

HUMAN BODY SYSTEMS

TODAY I WILL

 Explain how the body systems work together to

maintain homeostasis.

 Identify the organs skeletal systems and explain

their functions.

​You will see this pencil and will take notes, starting on slide 19

BODY SYSTEMS HELP MAINTAIN

 Homeostasis - maintenance of a constant

internal environment

Question: What could happen if homeostasis is NOT maintained
in an organ system?

Multiple Choice

Homeostasis

• allows for a wildly fluctuating internal environment

• is impossible in vertebrates

• is the maintenance of a relatively stable internal environment and often incorporates a form of feedback regulation

Multiple Choice

A balanced internal environment is called - 

• photosynthesis

• internal stimulus

• homeostasis

• external stimulus

Multiple Choice

Which situation best describes the act of maintaining homeostasis?

• An organism sweating when their body temperature begins to rise

• A plant on a window sill growing towards sunlight

• A bear hibernating in the winter months

• All of the above

cell

tissue

organ

Organ system

Organism

LEVELS OF ORGANIZATION

Multiple Choice

A group of similar types of cells that work together to do a specific job is called a/an _____.

• tissue

• organ

• stem cell

• organ system

Multiple Choice

A group of different tissues working together to do a job is called a/an _____.

• tissue

• organ

• stem cell

• organ system

Multiple Choice

A group of different organs working together to do a series of jobs is called a/an _____.

• tissue

• organ

• stem cell

• organ system

Multiple Choice

What is the correct order of organization

• tissues-cells-organs-organ systems-organism

• cell-tissue-organs-organ systems-organism

• organism-cells-tissues-organ systems-organism

• tissues-cells-organs-organ sytems-organism

Multiple Choice

When many organ systems work together it can form...

• organ

• cells

• organ system

• organism 

Multiple Choice

The ___________ is the basic unit of life

• organ

• cell

• atom

• tissue

Multiple Choice

This is a example of ........

• cell
• tissue
• organ 
• organ system

Multiple Choice

This is a example of ........

• cell

• organ system

• organ

• tissue

Multiple Choice

This is a example of ........

• organ

• organ system

• tissue

• cell

Multiple Choice

When many organ systems work together it can form...

• a cell

• an organ

• an organ system

• an organism

Cells, tissues, organs....work together to make organ systms

Skeletal System

STRUCTURE

 Composed of bones , ligaments and cartilage

 Ligaments and cartilage are found in joints,

which are places where bones meet

BONES ARE MADE OF…

 Minerals (calcium)

 Connective tissue (to be flexible)

 Bone Marrow (makes white and red blood cells)

 What is in your bones?

FUNCTIONS OF SKELETAL SYSTEM

 Protection for internal organs

 Storage of minerals (calcium)

 Blood cell production (bone marrow)

 Shape/Support

 Movement

 (1)Protection for internal organs

(2)Storage of minerals (calcium)

 (3)Blood cell production

 Happens in bone marrow

 Blood cells- red blood cell

white blood cells

(4) Shape and Support

THERE ARE 206 BONES IN YOUR BODY!

(5) Movement

Multiple Choice

The skeletal system works with what other system to create movement?

• circulatory

• skeletal

• muscular

• digestive

Multiple Choice

What is produced inside of your bones?

• blood cells

• oxygen

• carbon dioxide

• lactic acid

Multiple Choice

What are functions of the skeleton?

• Protection

• Movement

• All of these

Multiple Choice

The primary mineral stored by compact bone is

• Calcium

• Selenium

• Zinc

• Magnesium
