We are made up of CELLS! We have about 200 different types!

Each person contains more than 100 trillion cells in total 5-50 million of our cells die every minute

400 cells can fit on the head of a pin!

• Can you guess what body system they belong to?

Nervous system Coordinates the body’s response to changes in its

internal and external environments

Skeletal system   Stores mineral reserves and provides a site for

blood cell formation

Integumentary system (skin)   Serves as a barrier against infection and injury

Endocrine system    Eliminates wastes and maintains balance

Lymphatic/Immune systems Helps protect body from disease.

Muscular system Helps produce voluntary movement, circulate

blood, and move food

Reproductive system Produces reproductive cells

Respiratory system Provides oxygen and removes carbon dioxide

Excretory system Eliminates wastes and maintains balance

Circulatory system Brings materials to cells, fights infection, and helps

to regulate body temperature

Digestive system Converts food so it can be used by cells

• Circulatory• Digestive• Endocrine• Excretory• Immune• Muscular• Nervous• Reproductive• Respiratory• Skeletal• Skin

• Carries needed material to and waste away from the body• Takes in food, breaks it down, & absorbs nutrients• Controls many regulatory processes by mean of chemicals• Removes waste• Fights disease• Enables the body to move (voluntary & involuntary

motion)• Detects and interprets information from the environment

outside the body and from within the body• Produces sex cells & controls male & female characteristics• Supports the body, protects it and works with muscles to

allow movement• Protects the body, keeps water inside the body & regulates

body temperature

Body Systems

Body Systems work together

• If you get excited, the nervous system increases the heart rate

Human Body Team

All the systems play a part. How do they interact?

Which one is the most important?

Integumentary SystemSkin, Hair and Nails

• I cover and protect every place on the body!

• I am the first line of defense against invasion and injury.

• I retain body heat yet, have pores to release excess heat and wastes.

• I retain moisture and your body is almost 80% water!

Skeletal System• Without me, you’d have

no shape or structure…you’d be a blob.

• I make you able to move!• I make your red blood

cells that carry oxygen to all the cells.

• I protect the precious brain, heart and spinal cord.

Muscular System• The heart is made of

cardiac muscle.• The internal organs

are made of smooth muscle.

• Without the skeletal muscles the bones couldn’t move.

Respiratory System• I bring in the oxygen that is carried on the red

blood cells…without me you’d have no oxygen to carry!

• I carry the CO2 (waste gas) out of the body. • The circulatory system needs me for gas exchange.• The muscles need oxygen to move.• The brain needs

my oxygen to think.

Circulatory System

• I carry oxygen and nutrients to every cell in the body!

• I am the heart, the veins, the arteries, capillaries and blood.

• I transport the white blood cells to all the infections and injuries.

• Without me, the oxygen and the CO2 in the body couldn’t reach the cells or lungs.

Nervous SystemI tell everything what to do. I tell the heart when to beat, the body when to move, the digestive system to add enzymes.

I am the leader.

Digestive/Excretory System

• Without my system, the body would not be able to obtain energy and nutrients.

• I break down all the food stuffed in my mouth into usable nutrients and expel the wastes.

Reproduction System

• Without me, there would be not be any systems.

• I am how the species continues.
