Nervous
Reproductive
Respiratory
Skeletal
Integumentary

5. SKELETAL SYSTEM

6. Functions: Provides shape and support, enables you to move, protects your internal organs, produce blood cells, and stores certain materials until your body needs them
Made of two minerals:phosphorous and calcium
Contains cells and tissue
Cartilage is a connective tissue, flexible then bone (found on tip of nose and on ears)
Cartilage cover the ends of bones and serves as a cushion to keep from rubbing/ bumping against each other
Joint-place where two bones come together , allows bones to move in different ways (immovable and movable)
Thin, tough membrane cover all the bone except the end
Blood vessel and nerves enter and leave the bone through membrane
Marrow-soft connective tissue within spaces in the bone

7. MUSCULAR SYSTEM

8. Functions: Keeps your heart beating, make a smile, and move the bones of our skeleton
About 600 muscles in our body
Muscle act voluntary or in voluntary
3 Types of Muscle
-Skeletal-attached to the bone of skeleton. Tendon is a tissue that attach muscle to bone
-Smooth-involuntary muscle, help in the digestion process
-Cardiac-involuntary, they do not get tired. EX. heart beats
Skeletal muscle work in pairs

9. Integumentary System Skin, Hair, Nails

10. Function-covers the body and prevent loss of water, protect body from injury and infection, maintain temperature, eliminates waste, gathers information from environment and produce vitamin D
Skin is made up of two layer. Epidermis the top layer and dermis the bottom layer
Pores- opening through which sweat reaches the surface of the skin
Follicle-structure in the dermis of the skin from which a strand of hair grows
Protect the skin by avoiding too much sunlight. Eating properly, and drinking water.

11. DIGESTIVE SYSTEM

12. Function: breaks down food into molecules that the body can use
Function: breaks down food into molecules that the body can use. Molecules are absorbed through the blood. Then waste is eliminated from the body.
2 types of Digestion
-Mechanical - food is physically broken down into smaller pieces
-Chemical - chemical produce by the body breaks the food into small building blocks
Absorption- process by which nutrient molecules pass through the wall of your digestive system into your blood

13. CIRCULATORY SYSTEM

14. Function: Carries needed substances to cells and carries waste products away from cells
Consist of heart, blood vessel, and blood
The system is a disease fighter because it sends cells to attack disease-causing microorganism
Blood is made up of plasma, red blood cells, white blood cells, and platelets
Lymphatic system is a network of veins that returns fluid back to the bloodstream

15. RESPIRATORY SYSTEM

16. Function: Moves oxygen from the outside environment into the body
Function: Moves oxygen from the outside environment into the body. It also removes water and carbon dioxide from the body
Respiration is the process in which oxygen and glucose undergo a complex series of chemical reactions inside cells
You breathe about 20,0000 breaths on an average daily
Our larynx (voice box) and our two vocal cord helps us to speak

17. EXCRETORY / URINARY SYSTEM

18. Function: Collects waste produced by cells and remove the waste from the body
The removal process is called excretion
Consist of Kidneys, ureter, bladder, and urethra, lungs, skin, and liver
Nephrons are tiny structures that remove waste from blood and produce urine

19. IMMUNE SYSTEM

20. Function: Cells of the immune system work together to combat infection
Infectious diseases are caused by pathogen (Organism that cause disease)
-bacteria fungi
-viruses protist
Disease are spread person-to-person, animal bites, or by pathogen naturally in the environment
Our skin, breathing passages, mouth, and stomach are barriers that keep pathogens out
White blood cells, T-cells, and B-cell helps our body to combat diseases in our body

21. NERVOUS SYSTEM

22. Function: Receives information about what is happening inside and outside your body . Also, it directed the way in which your body respond to this information. Help to you to move, think, and taste
Stimulus-a change in an organism’s environment that make it react
Response-what your body does in reaction to the stimulus
Nervous system maintain homeostasis by directing the body to respond appropriately to the information it receives.
3 Kinds of neuron
-sensory-picks up stimuli from the internal or external environment and converts each stimuli into a nerve impulse
-interneuron-neuron that carries nerve impulses from one neuron to another
-motor-sends an impulse to the muscle, and the muscle contract in response

23. ENDOCRINE SYSTEM

24. Function: Controls many of the body’s daily activities as well as long term changes such as development
Hormones-a chemical product of a endocrine gland that speeds up or slows down the activity of an organ or tissue
Hypothalamus – A tiny part of the brain that links the nervous system and endocrine system
Pituitary gland-communicates with the hypothalamus to control many body activities

25. REPRODUCTIVE SYSTEM

26. Function:. Male-to produce sperm and the hormone testosterone,
Function: Male-to produce sperm and the hormone testosterone, Female-to produce eggs, and if egg is fertilized nourish a developing baby until birth
When a egg becomes fertilized by sperm it called an zygote, then develop into an embryo, than into a fetus
Birth of a baby takes places in three stages: labor, delivery, after birth
Puberty is a period of sexual development in which the body becomes able to reproduce
