Chapter 1

structural anatomy study of body structures(studies the structures of body parts and there relationships to one another..to cut apart)
physiology applications of structures function usually divided by systems..concerns the function of the body, in other words how the body parts work and carry out their life-sustaining activities.
gross seen by your eye (regional, systemic and surface-pulpate)
microscopic can't be seen by your eye
cytology one cell screws up it equals cancer
histology study of tissues
developmental traces structural changes that occur in the body throughout the life span
embryology before birth, fix things like birth defects
levels of oranization how are you made up (chemical, cellular, tissues, organ, organ system, organismal)
chemical Na+1k+pump (sodium potasium)
cellular smallest living things (cell)
Ca calcium
tissues groups of similar cells with common functions (epithelium, muscle, connective, nervous)
epithelium covering
muscle smooth (involuntary, straiated (your choose) cardiatic (these contract for a reason, some you control some you can't control)
connective connects two things
nervous communication system
organ comprised of at least two tissues (usually 4) that performs a specific function
organ system organs working together for a common purpose
organismal all organ systems working together to promote life
skin is the largest living organism in your body
renal physiology concerns kidney function and urine production
neurophysiology explains the workings of the nervous system
cardiovascular physiology examines the operation of the heart and blood vessels
functional characteristics necessary to maintain life in humans digestive, respiratory, cardiovascular, urinary and integumentary systems
survival needs nutrients, oxygen, water, temperature, atmospheric pressure
barametric pressure increases the fluid amount in your body. Goes up causing some people to complain about joint pain.
necessities of life boundries, movement, responsiveness, digestion, excretion, reproduction, growth and metabolism.
catabolism breaks down things
anabolism builds up
cellular respiration this happens from catabolism and anabolism from your cells. Gives you fuel. (ATP)
homeostasis maintains relatively stable internal conditions even though the outside world is unstable
negative feedback change in opposite direction of stimulus (80%)
positive feedback change in same direction of stimulus. you give and you get back.
