Organ System Interactions

Join quickly!

Your Bellringer/DO NOW is next!

Multiple Select

Select ALL the correct human organ systems from the list below:

• Periodic system

• Circulatory system

• Endocrine system

• Tri-Rail system

• Nervous system

Multiple Choice

The nervous system works together with many of your other organ systems to maintain homeostasis.

• True

• False

Our organs work together!

When one or more organs work together, it's called an organ system.

For example...

Multiple Choice

Which of these organ systems breaks down food into nutrients?

• Respiratory system

• Circulatory system

• Digestive system

• Nervous system

But organ systems also work together!

They interact in a bunch of ways to carry out the complex functions we're used to, like: walking, eating, and growing up!

Example #1: Moving

On the surface level:

^{+ Muscles move bones to run}

But also, what is coordinating it all?

^{+ The nervous system!}

And where is it getting energy from?

^{+ The digestive system!}

Where do the cells get oxygen from?

^{+ The circulatory and respiratory systems!}

Example #2: Eating

You'd think it's just the digestive system turning food into nutrients, right? Well, that's one level...

It's also:

+ Bones (teeth, mandible) chewing

+ Muscles moving food along

+ Blood vessels carrying nutrients

+ Brain bossing everyone around

+ Hormones making you hungry/full

The things you do to keep alive must be done by more than one organ system!

That's what makes you an organism.

Multiple Choice

One system interaction that we all need to live is breathing. Which other organ system works with the respiratory system to do it?

(Hint: Your chest/lungs moves up and down when you breathe!)

• the digestive system

• the endocrine system

• the muscular system

The

Integumentary System

Covers the outside of the body.

+ Protects muscles and organs

+ Regulates temperature

+ Fights germs, keeps them out

Three layers:

+ epidermis, dermis, subcutaneous.

Multiple Choice

Which of these scientific terms are part of the skin?

• Epidermis and dermis

• Elastic and putrid

• Conductive and respondent

The Muscular System

Helps you move and protect body.

+ Covers bones/organs in layers

+ Contracts and relaxes to move

+ Consumes energy to work well

There are more than 600 muscles in a human body! Like:

+ Biceps, triceps, pectorals, etc.

The Skeletal System

Helps to move and protect organs.

+ Attached to muscles via tendons

+ Attached to bones w/ ligaments

+ Also creates blood cells!

An adult human has about 206 bones - children have more!

+ Long bones don't fuse until older

Open Ended

List all the muscles and bones that you know the names of below:
