The+Transport+System

10/4/11

 * Photosynthesis and Cell Respiration test on Friday (10/7)
 * intro. transport system
 * animation

HW;

 * ===study for photosynthesis and cell respiration test===
 * ===read chapt. on transport system (pg. 219) over the next few days===

10/5/11

 * heart dissection
 * Check out [|this] link to see what the valves actually look like in action!
 * another good animation, particularly if you are interested to see how electrocardiograms, heart sounds and blood pressure are involved

10/6/11

 * review for photosynthesis/ cell resp. test
 * wrap up heart dissection

10/7/11
photosynthesis/ cell resp. test

 * heartbeat control... myogenic contraction, pacemaker, nerves
 * heartbeat control... medulla and epinephrine (adrenaline)
 * medulla sends nerve impulses to SA node to change rate and strength of contractions
 * adrenaline (secreted by adrenal glands) travels to the SA node to speed up and strengthen contractions (fight or flight response)
 * gas exchange/ respiration
