1. Put correct system with the picture (write in pencil)
Circulatory digestive
Reproductive skeletal
Nervous muscular
Endocrine Respiratory
Excretory Immune Integumentary

2. Cell, tissue, organ, organ system, organism

3. The 3 main parts of The Circulatory system are
The Heart
Pump blood
The Blood Vessels
Bring blood around
Blood
Carry oxygen, nutrients and waste

4. Circulatory system Functions
Carries blood and needed substances (oxygen and nutrients) to cells and waste products away to the cells and all your body.
Carries cells that fight disease
White blood cells.

5. Nervous system
Main Function: Control for the rest of the systems and body functions
Receives information from inside and outside the body
Directs the way that the body will respond
Main structures
brain, spinal cord, nerve cells (neuron), sense organs

6. Neuron

7. Reproductive system Function
allows more humans to be born to continue the species
Main structures
egg, sperm, ovaries, testes

8. Endocrine system Functions
produces hormones that control the levels of other substances in the body
Structures
ductless glands, hormones

9. Immune system Main function: fights germs entering the body
Main parts: lymph, white blood cells, antibodies

10. Integumentary system Main organ: SKIN Functions
Protects the other body systems from injury, infection
Helps the body maintain homeostasis
synthesis of vitamin D Required for bone formation
Excretion of salts, water and wastes
sensory perception
Main organ: SKIN

11. Respiratory system Functions
Moves oxygen from the outside environment into the body.
Removes carbon dioxide and water from the body
Main Structure: Lungs
Also bronchi, bronchioles, alveoli, nasal cavity, pharynx, larynx, epiglottis, trachea,

12. To bring oxygen around your body?
Oxygen molecules are transport to the cells by the Circulatory system
The blood absorb the Oxygen molecules in the lungs that are part of Respiratory system
Conclusion the circulatory and the respiratory system work together.

13. Excretory system Function
This system collects the waste produced by the cells and removes the waste from the body.
Main organ: Kidneys
Others are sweat glands, urinary bladder, urethra, ureter

14. Digestive system Function
Breaks down food small enough to get into your cells.
Main Structures
stomach, esophagus, mouth, salivary glands, large and small intestines, rectum, villi

15. Skeletal system Functions
protects organs, produces blood, stores minerals, movement and support
Main structures:
bones, joints, ligaments

16. Muscular system provide movement for the body The main function
skeletal: Pull bones to cause movement
smooth: Organ muscle, and vascular walls
cardiac: Heart contractions
Main structures: 3 types of muscle
And tendons

17. Rap of the systems
Systems song
