Urinary system

Eliminates nitrogenous wastes from the body. Regulates water, electrolyte and acid-base balance of the blood.

True

Digestion is an external process.

True

Many Americane get 1/2 of the reccomened amount of Vitamin D

3 Principles of healthy eating

Variety, Balance, and Moderation

nutrient density

a measure of nutrients provided per calorie of food

water

a medium in which ALL body chemistry occurs also heats and fuels our bodies

enzyme

a protein that changes the rate of chemical reactions

Acids

are compounds that produce hydrogen (H+) ions in solution.

Bases

are compounds that produce hydroxide ions (OH-) in solution.

function of pancreas

bicarbonate the neutralizes acids, produces insulin

A primary function of the digestive system is the

breakdown of food into nutrients.

catabolism

breaking down molecules

Digestive System

breaks down food and absorbs nutrients

anabolism

building up molecules

macronutrients

carbohydrates, lipids, proteins & water

organic nutrients

carbohydrates, lipids, proteins, vitamins

Nervous System

controls sensation, thought, movement, and virtually all other body activities

empty calories

Vitamins

enables enzymes and enable chemical reactions

Dietary Reference Intakes (DRIs)

Reproductive system function

produce offspring

function of liver

produces bile

Integumentary system

protection, water retention, thermoregulation, vitamin D synthesis,

In conducting experimental research, the purpose of having a control group is to

provide a standard for comparison with the treated group.

functions of carbs

provide energy, mostly used to "fuel" the body primarily to the brain and nervous system, but muscles as well

structural/functional claim

refers to health claim that do not require approval but must notify the FDA.

Function of vitamins and minerals

regulation of body processes (chemical reactions)

Quantitative Research

research that collects and reports data primarily in numerical form

Qualitative Research

research that relies on what is seen in field or naturalistic settings more than on statistical data

segmentation

sloshes food back and forth in both directions promoting further mixing of the chyme

the act of chewing

fortification
