1. How is your body organized?
cell
The basic unit of structure and function in living things
Carry on the processes that keep organisms alive
tissues
A group of similar cells that perform the same function
Types: Muscle, nervous, connective (support) and Epithelial (cover the body surfaces)
organs
A structure made up of different kinds of tissue
A specific job more complex than tissues… ex. Heart pumping blood
System
A group of organs that work together to carry out major functions
Organism
The living thing… can be as small as one cell or have many complex organ systems

2. What are the major body systems?
Bones, cartilage, ligaments and tendons
Supports body, protects organs, allows movement and produces blood cells
Skeletal system
Skin, hair, nails and glands
Guards against infection and keeps body temperature
Integumentary system
Skeletal (movement), smooth (moves food) and cardiac (pumps blood)
Muscular system
Heart and blood vessels transport oxygen nutrients and waste
Circulatory system
Nose, trachea and lungs bring in oxygen and remove carbon
Respiratory system

3. Digestive System Excretory system Nervous system
Mouth, stomach and intestines, break down food, absorb nutrients and remove waste
Digestive System
Kidney, urinary, bladder, skin remove waste from body
Excretory system
Brain, spine and nerves control body's responses to change
Nervous system

4. Reproductive system Endocrine System FEMALES: ovaries, uterus, vagina
MALES: penis, testes
Reproductive system
Glands such as the thyroid, pancreas and adrenal
Controls growth and development, maintains homeostasis
Endocrine System

5. How do you move?
Muscles and bones, Ligaments and tendons, work together, making your body move. The nervous system tells your muscles WHEN to move
Joint: a joint is a place where two bones come together
Bones can only move at a joint otherwise they break

6. How do we breath? Muscles expand your chest allowing air to be pulled into lungs.
Breathing
Air moves into lungs
Oxygen moves into the blood
Oxygen is delivered to cells
waste moves into the bloodstream
Waste is carried to lungs where it is expelled

7. What systems control body functions?
The nervous system and the endocrine system work together to control body functions
Your nervous system responds to a stimulus
Hormones are chemical signals sent from your endocrine system
