Human  Physiology     Day  1  (March  29)  Introduction-­‐     Physiology:  the  study  of  how  things  work  in  the  body   -­‐Regulations  of  our  parts   -­‐Cells,  tissues  and  our  organs  they  all  work  together:   Interdependence   -­‐Anatomy  –  Naming  things,  describing  things.  Names  the  parts  of  the   body.     -­‐Our  cells  require  each  other  in  order  to  live   -­‐We  are  multicellular  organisms                  -­‐we  can  be  complex   -­‐we  face  “challenges”  alter  our  internal  environment  e.g.  “ to  hot”  -­‐>  we  can   compensate   Homostasis:

 Amount  of  NA+  in  the  blood  is  about  145mM   4.  Amount  of  oxygen  in  the  blood  =  100  mmHG   Blood  is  transferred  through  the  capillary  and  exchanges  properties  through   the  blood  and  fluid  in  the  cells  (extracellular  fluid).       What  happens  if  they  is  a  disturbance?     -­‐Activate  homeostatic  reflex  loop  -­‐>  A  response  it  counters  the  disturbance     Example:  Tb  gets  to  high  (100  degrees  F)  <-­‐  this  is  the  disturbance   Sensory  receptors  receive  the  body  temp  and  sends  information  through  an   afferent  pathway  to  the  central  processor.  And  compares  the  high  temp  to   the  set  temperature  98.6.    The  central  processor  sends  info  through  n   efferent  pathway  to  control  an

Jim McGreen Ohio University

"Knowing I can count on the Elite Notetaker in my class allows me to focus on what the professor is saying instead of just scribbling notes the whole time and falling behind."

Allison Fischer University of Alabama

"I signed up to be an Elite Notetaker with 2 of my sorority sisters this semester. We just posted our notes weekly and were each making over $600 per month. I LOVE StudySoup!"

Bentley McCaw University of Florida

"I was shooting for a perfect 4.0 GPA this semester. Having StudySoup as a study aid was critical to helping me achieve my goal...and I nailed it!"

Parker Thompson 500 Startups

"It's a great way for students to improve their educational experience and it seemed like a product that everybody wants, so all the people participating are winning."
