atom, molecule,organelle,cell,tissue,organ,organ system, organism
The organization of an organism
cells
smallest unit of living things
tissues
a group of similar cells that have a common function
organ
structure composed of at least 2 tissue types that performs a specific function for the body.
necessary life functions
maintaining boundaries, movement, responsiveness growth,digestion, excretion, reproduction and metabolism,
integumentary system
system composed of hair, skin and nails, covery external body and protects deeper tissue
skeletal system
system composed of bones and joints, protects and supports, provides bodys frame work for muscles
muscular system
system composed of skeletal muscles and allows for movements and manipulation of the envioronment
nervous system
composed of spinal cord, brain and nerves. control system of the body and responds to changes by activating muscles and glands
endocrine system
COMPOSED OF GLANDS THAT REGULATE THE PROCESSES SUCH AS GROWTH AND REproduction
cardiovascular system
composed of heart and blood vessels, transports blood which cariies oxygen, CO2 nutrients and waste. pumps blood
lymphatic system
composed of red bone marrow, nodes, spleen, vessles and thoracic duct, which disposes debris in the lymphatic stream. Immune reponse.
respiratory system
composed of nasal, pharynx, larnx, trachea broncus and lungs, keeps blood supplied with O2 and removes CO2
digestive system
COMPOSED OF ORAL CAVITY, ESOPHOGUS liver, stomache, intestines and rectume. breaks down food and absorbs nutrients
urinary system
Composed of kidneys, ureter, bladder and urethra, rids the body of acid-based wastes.
reproductive system
System that functions in producing off springs
homeostasis
the ability to maintain an internal balance even when outside world changes. dynamic state of equilibrium
nervous and endocrine system
2 systems most responsible in maintaining homeostasis
receptor, control center, effector
3 main parts of homeostatic control
receptor
sensor that monitors changes and sens information in an afferent path to control center in negative feedback
control center
determines the set point in feedback, recieves from receptor and send infor efferently to effector
effector
responds to to feed back from the control center, shuts off or enhances stimulus
negative feed back
homeostatic control mechanism that shuts off original effect of stimuli or reduces intensity.
negative feed back
body tempertaure and controlling blood sugar are an example of which feed back mechanism?
positive feedback mechanism
homeostatic control mechanism that enhances the original stimulus so that the response is accelerates
positive feedback mechanism
blood clotting is an example of which type of homeostatic control mechanism
anatomical position
body standing errect with palms facing forward and thumbs pointing away from the body
