2. Submucosa
3. Muscularis Externa
4. Serosa
WHAT DO BACTERIA DO IN THE L.I?
-provide nutrient from food that we cannot extract ourselves
-also synthesizes vitamin B and vitamin K

WHAT IS METABOLISM?
-the sum of all biochemical reactions in the body
-anabolic (dehydration synthesis) and catabolic (hydrolysis)

PRODUCTS OF ANAEROBIC RESPIRATION
-2 ATP PER GLUCOSE
-LACTIC ACID
PRODUCTS OF AEROBIC RESPIRTATION
-32 ATP
ISOTONIC CONTRACTION
-tension in muscle remains constant while muscle changes length.
CONCENTRIC CONTRACTION: tension great enough to overcome load, muscle shortens (picking up a book)
ECCENTRIC CONTRACTION: tension resists movement of load and slows lengthening process (slowly lowering a book)
ISOMETERIC CONTRACTION
-tension in muscle is not great enough to overcome load on muscle and there is no change in length
WHAT DOES A MOTOR UNIT CONSIST OF?
-MOTOR NEURON
-SKELETAL MUSCLE FIBRE
TWITCH CONTRACTION
-brief contraction of a muscle fibers in a motor unit - response of single stimulation
WHAT IS A CONTRACTION MEASURED ON IN LAB?
MYOGRAM
WHAT MACROMOLECULE = MOST ENERGY?
LIPIDS
WHAT IS KETOACIDOSIS?
-extra acetyl groups are metabolized in liver when there is alot of fatty synthesis
-when many ketone bodies accumulate blood Ph drops and diabetes can form
