- Normal Flora/Fauna
- Microbs that live in the large intestines and they also occupy space so that bad things cant "move in", they are found on every surface of the body.
- Normal flora/fauna produce
-
Vitamin K and B5
Bilirubins
Indigestible Compounds - Coliform
- The specific flora/fauna that are found in the large intestines
- Rectum
-
Used for temporary storage. The opening is called the anus which has the internal and external anal sphincter.
Internal-Involuntary
External-Voluntary - Defication Reflexes
- Happen when the feces fill up the rectum which causes it to stretch
- Diarrhea
- Feces that have moved from the ascending colon too quickly. This can cause dehydration and you cant maintain blood flow
- Constipation
- Not enough water in the feces and spending too much time in the colon. You need to drink water and consume fiber to help with this problem.
- Electrolytes
- diffusion and active transport
- Water Soluble Vitamins
- there are 9 of them. If you have access then they are excreted in the urine
- 4 Fat soluble Vitamins
-
A,D,E,K
The way we absorb these vitamins is by eating fat - 2 Typles of metabolism
- Anabolism, Catabolism
- Aerobic Cellular Respiration
- C6H12O6+6O2+H2O--> 6CO2+H2O+38ATP
- Heat
- Becomes a waste product, but we capture that heat to maintain homeostasis
- Shivering
- Muscles go through little contractions to burn up ATP
- Metabolic Rate
- Speeds up to burn ATP
- Nutrients
- Vitamins, minerals and water-your body absorbs them as they exist, it does not change them
- Nutrition
- Absorption of nutrients from food
- Chymeric
- Changeable-kids need different nutrients than adults
- BMR-Basal Metabolic Rate
-
measure of the caloric needs per unit of time
Sitting down and doing nothing:
70C an hour
1800 Kilocalories per day - How age affects BMR
-
5,000 calories a day-kids
Men have slightly higher BMR than women because of muscle
Genetic differences-whites to blacks
Overweight people compared to not overweight people
Inshape people compared to non-inshaped people - Lipoproteins
-
Low Density Molecule
High Density Molecule - Low Density
- molecules that pick up cholesterol from liver and takes it to the perpherial tissues, the tissues use some and has some left over
- High Density
- picks up left over cholesterol from perpherial tissues and takes it back to the liver
- C reactive protein
- a by product of inflammed arteries
- Triglycerides
- Building blocks for fats
