Cells & Body Systems Flying Start Health/ Science
Introducing the human body • http://video.nationalgeographic.com/video/player/science/health-human-body-sci/human-body/human-body-sci.html -National Geographic- Human Body 101 (3 minutes)
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!
We made of CELLS? • Cells are the Building Blocks of LIFE • Cells Tissues Organs Systems

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 What's My Function?

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 needsmy 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 System I 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.
