Bell Jar Demo:
Rubber sheeting (diaphragm) is pulled down (contracting or expanding) à balloons (lungs) inflate because pressure decreases and volume increases, forcing air to flow in (inhale)
Rubber sheeting (diaphragm) pushed in (relaxing) à balloons (lungs) deflate because pressure increases, volume decreases and air is forces out (exhale)
 
Flow Chart of Pathway of Air:
Nasal Cavity -> pharynx (throat) -> trachea -> bronchi -> bronchioles -> alveoli
Function of nasal cavity: moistens, warms, & filters the air
Function of alveoli: exchange of oxygen and carbon dioxide with blood (diffusion)

Table of Wastes from Each Organ:
Lungs: water, carbon dioxide
Liver: urea
Skin: water, salt, urea
Kidney: water, salt, urea
 
Label the Excretory System
  1. Kidney
  2. Ureter
  3. Bladder
  4. Urethra

Answers to the Urine Article & Questions
  1. Yellow-colorless, red tint, reddish-purple, rosy glow, greenish, blue tint, brown, smoky or black
  2. 95% water plus urea, salts, minerals, creatinine, uric acid, hormone remnants, toxins
  3. That's because red blood cells don't last forever.  Worn out cells are processed by the liver and the break down of hemoglobin results in a yellow pigment urochrome.

Answers to the Sweat Article & Questions
  1. In the brain; It controls temperature, sends a message to his sweat glands to start sweating
  2. Sports drinks provide carbohydrates for energy and replace salty substances lost through sweating.
  3. The bacteria on your skin produces the stink from digesting proteins and acids found in sweat
