organ
organ system
organism
cell - CORRECT ANSWER--composed of organelles
-the basic units of structure and function of the body
tissue - CORRECT ANSWER-layer or mass of cells with specific function
organ - CORRECT ANSWER-group of different tissues with a function
,system/ organ system - CORRECT ANSWER-group of organs with common function
homeostasis - CORRECT ANSWER-maintenance of a stable internal environment
metabolism - CORRECT ANSWER-all of the chemical reactions in an organism that support life
positive feedback loop - CORRECT ANSWER--homeostatic mechanism
-response enhances or exaggerates original stimulus
-uncommon in body
-short lived
-examples are contractions in labor by oxytocin and platelet plug formation+ blood clotting
negative feedback loop - CORRECT ANSWER--homeostatic mechanism
-most feedbacks in the body
-response reduces or shuts off original stimulus/ goes in opposite direction
-examples are regulation of body temperature, regulation of blood glucose by insulin
Human life depends on what 5 environmental factors? - CORRECT ANSWER-1) water
2) food
3) oxygen
4) heat
5) pressure
1) Water - CORRECT ANSWER--most abundant substance in body
- environment for metabolic processes
-required for transport of substance
,-regulation of body temperature
2) Food - CORRECT ANSWER--provides necessary nutrients
-supplies energy
-supplies raw materials for building living tissue
3) Oxygen (gas) - CORRECT ANSWER--one fifth of air
-used to release energy from nutrients
4) Heat - CORRECT ANSWER--heat is a form of energy in out environment
- helps maintain body temperature
- partly controls rate of metabolic reactions
5) Pressure - CORRECT ANSWER--application of force on an object
- atmospheric pressure// important for breathing
-hydrostatic pressure// keeps blood flowing

anatomical position - CORRECT ANSWER-To stand erect with arms at the sides and palms of the
hands turned forward
Identify the basic position terms associated with describing body parts. - CORRECT ANSWER-
superior-above
inferior-below
anterior-front of the body
posterior- toward the back
medial-toward the midline
lateral-away from the midline
distal-farther from the origin of a body part or the point of attachment of a limb to the body
trunk
proximal-closer to the point of attachment
superficial-near the surface
deep-more internal
