Definition of kcalorie
A calorie is a measure of energy expenditure. The calories referred to in diet and exercise are kilocalories (kcal)
Overnutrition
A state in which nutritional intake greatly exceeds the body's needs
Role and function of lymphatic system
Aid in picking up and transporting the majority of products of fat digestion and absorption. Also takes up excess fluid. Not run by a pump but by muscle contractions.
Role and action mucus enzyme of Bile
Aids fat digestion in the small intestine by suspending fat in water
Nutrients that can provide energy and kcals per gram for each macronutrient
Carbohydrate provides 4 calories per gram.Protein provides 4 calories per gram.Fat provides 9 calories per gram.
Malnutrition
Failing Health due to long-standing dietary practices that do not meet nutritional needs
Effects of a low carbohydrate diet and development of ketone bodies
It brings many risks the worst being death. Because when you increase protein break down protection for vital organs is lost. Ketone bodies are break down products of fat
Locations where digestive enzymes are produced
Pancreas Small Intestines *Saliva Glands *Stomach
Role and function of phytochemicals
Phytochemicals are naturally occurring, biologically active chemical compounds in plants. The prefix 'phyto' is from a Greek word meaning plant
Function of the epiglottis
Prevents the bolus(swallowed food) from entering the trachea(wind pipe)
Definition of nutrient density
Provides a large amount of nutrients for a small amount of calories
Location where most digestion takes place
Small Intestine
Undernutrition
When nutrient intake does not meet nutrient needs - You can still over eat and have this
Psychological and physiological influences on desire to eat hunger vs. appetite
-Hunger is the physiological NEED for food.

Process of fat digestion
1. Mouth: some hard fat begins to melt 2. Stomach: churning action mixes fat with stomach acid -Lipase breaks apart a small amount of fat 3. Liber: makes bile, stored in gallbladder, released into small intestine Small intestine: emulsifies fat with digestive juices 4. Pancreas: produces pancreatic lipase (which enters small intestine)
Endocrine system
Consists of various hormone and secrete glands. Has major regularly function over reproduction and cell metabolism
Risk factors for heart disease
High blood pressure, High blood, cholesterol, Diabetes, Smoking, Being overweight, Being physically inactive, Having a family history of early heart disease, Age (55 or older for women).
Factors that influence development of diabetes
Immune system disorder, Decreased release of insulin, Older age, Obesity, physical inactivity, family history
Effect of insulin on a non-diabetic
It would take a really high dose to kill someone. But most of the time the body would recognize it and correct it before anything drastic happened. It does stop the Pancreas but normal activity should continue
Name associated with fat as it is stored in the body
Lipid
Location and function of digestive system sphincters
Lower Esophageal Sphincter - end of Esophagus Pyloric Sphincter - Base of the Stomach Ileocecal Sphincter - Between Small & Large Intestine Anal Sphincter (2) - Anus
