System | Function or other |
Levels of Organization | Cell, Tissue, Organ, Organ System, Organism |
Integumentary System | Protects the other body systems from injury and infection
Helps the body maintain homeostasis
Synthesis of Vitamin D required for bone formation
Sensory perception |
Integumentary System Structures | Main organ: skin |
Muscular system | provide movement for the body |
Muscular System Structures | skeletal: pull bones to cause movement
smooth: organ muscle, and vascular walls
cardiac: heart contractions
3 types of muscles and tendons |
Circulatory System | carries blood and needed substances oxygen and nutrients) to cells and waste products away to the cells and all your body |
Circulatory System Structures | carries cells that fight disease
white blood cells |
3 main parts of the circulatory system | the heart
- pump blood
that blood vessels- bring blood around
blood
- carry oxygen, nutrients, and waste |
Respiratory System | Moves oxygen from the outside environment into the body
Removes carbon dioxide and water from the body |
Respiratory System Structures | Main structure: lungs
also bronchi, bronchioles, alveoli, nasal cavity, pharynx, larynx, epiglottis, trachea |
To bring oxygen around your body | oxygen molecules are transport the cells by the circulatory system
the blood absorb the oxygen molecules in the lungs that are part of the respiratory system
conclusion the circulatory and respiratory system work together |
Digestive System | breaks down food small enough to get into your cells |
Digestive System Structures | main structures: stomach, esophagus, mouth, salivary glands, large and small intestines, rectum, villi |
Excretory System | collects that waste produced by the cells and removes that waste from the body |
Excretory System Structures | main organ: kidneys
others are sweat glands, urinary bladder, urethra, ureter |
Immune System | fights germs entering the body |
Immune System Structures | main prats: lymph, white blood cells, antibodies |
Nervous System | control for the rest of the systems
- receives information from inside and outside the body
- directs that way that the body will respond |
Nervous System Structures | main structures: brain, spinal cord, nerve cells, sense organs |
Reproductive System | allows more humans to be born to continue the species |
Reproductive System Structures | Main structures: egg, sperm, ovaries, testes |
Endocrine System | produces hormones that control the levels of other substances in the body |
Endocrine System Structures | Structures: ductless glands, hormones |
Skeletal System | protects organs, produces blood, stores minerals, movement and support |
Skeletal System Structures | Main Structures: bones, joints, ligaments |
