Organism
(body)
BODY TISSUES
•Tissues: group of cells working together
BODY TISSUES
•Muscle: contract in coordination upon stimulation
•Skeletal: voluntary movement
•Cardiac and smooth: involuntary movement (you can’t
consciously control their movement)
BODY TISSUES
•Nervous: receive and transmit information and
signals (made of cells called neurons)
•Doesn’t grow back once damaged
•Long extensions allow for fast communication
BODY TISSUES
•Epithelial: cover inner and outer surfaces of bodies,
cavities, and canals
BODY TISSUES
•Connective: bind, support, and protect structures in
the body
•Bone, cartilage, tendons, fat, blood
ORGAN SYSTEMS
•Organs: tissues working together
•Organ systems: two or more organs
working together for a specific
function
ORGAN SYSTEMS
•Muscular: support and
movement
•Skeletal: protection and
support
ORGAN SYSTEMS
•Circulatory: transport of •Respiratory: gas
gases, nutrients, waste,
exchange
and chemicals to all
parts of the body
ORGAN SYSTEMS
•Immune: fights
pathogens
•Integumentary (skin):
protection
ORGAN SYSTEMS
•Endocrine: controls body •Nervous: regulation,
functions via chemical
conduction, and
messengers
coordination
ORGAN SYSTEMS
•Excretory: removal of
liquid, gas, and solid
wastes
•Digestive: breakdown
and absorption of food
ORGAN SYSTEMS
•Reproductive: production of
sex cells and in females
producing babies
BODY CAVITIES
•Organs housed and protected in cavities
•Cranial: brain
•Spinal: spine
•Thoracic: heart and respiratory organs
(diaphragm separates thoracic and abdominal)
•Abdominal: digestive system organs
•Pelvic: reproductive and excretory organs
