what are the 4 different types of chemical reactions?
Synthesis, Decomposition, Exchange, and Reversible
Integumentary System
(Protecting System) body protecting system that includes the hair, skin, and nails
Skeletal System
(Protecting System) helps support movement, framework, and posture.
* this system is the storage of inorganic salts and also produces red blood cells
(main organs: bones, cartilage, ligaments, and tendons)
Muscular System
(Body Protecting) also supports movement and posture but is also the main source of body heat
Nervous System
(Integration and Coordination) helps coordinate and unite organ function through nerve impulses and neurotransmitters ; usually rapid, short term effects
Endocrine System
(Integration and Coordination) helps coordinate and unite organ function through chemical messengers and hormones; typically slower, more long lasting effects
Cardiovascular System
(Transport) aids in the transportation of gases, nutrients, blood cells, hormones, and waste
Lymphatic System
(Transport) aids in transportation of fluids from TISSUE space in blood and carries fats from digestive system to blood
*helps defend body against infection
Digestive System
(Absorption and Excretion) receives and breaks down food and excretes waste
Respiratory System
(Absorption and Excretion) absorbs oxygen by moving air in and out of the body and exchanges gases between air and blood
Urinary System
(Absorption and Excretion) removes blood waste , regulates electrolyte and water balance and produces and excretes urine
Reproductive system
(Absorption and Excretion) produces hormones and produces and transports sex cells
Ion
atom that gains or loses electrons to become stable
cation
positively charged ion
Anion
negatively charged ion
ionic bond
strong chemical bond formed when opposite charge ions attract
