Document Summary
Lungs: transports oxygen and carbon dioxide to the heart and circulaion. Skeletal muscle: demands for fuel, everything else meets the demands, takes up oxygen and fuels, gets rid of fuel by-products (lactate), co2, heat, not all by-products are bad, get send to other issues through circulaion. Main sources of food (fuel: carbohydrates, fat, protein: create muscle mass, enzymes, don"t want to break down for fuel. Energy: breaking down and remaking atp to adp + p. Work: physiological funcions, heat is produced, na-k pump, myosin binding to acin (cross bridges), ca to reiculum. Atp lost as work, need fuel for atp. Study of energy transfer via chemical reacions in living issues: thermodynamics which includes in muscle contracion. 1st law: energy cannot be created nor destroyed only transferred from one form to another. You input 100 units of fuel, and also release 100 units, some is for work and some lost as heat.
