8345213593Describe the function of the mouthphysically breaks down food, mixes with saliva, digestion of starch with salivary enzymes, initiates the swallowing reflex0
8345213594Describe the function of the esophagusno digestion, bolus is rhythmically pushed down the esophagus by the muscles, mucus is secreted to make it slippery1
8345213595Describe the function of the stomachstores food until processing, forms chyme, controls movement of chyme into small intestine, mucus secreted, hydrochloric acid is secreted2
8345213596Describe the function of the small intestinefinishes the process of digestion and absorption, hormonal messenger systems communicate with other organs to release bile and digestive enzymes, peristalsis continues3
8345213597Describe the function of the large intestinesome digestion can occur by the naturally occurring bacteria that live in the colon, bacteria can synthesize some absorbable vitamin K4
8345213598Describe the function of the liverperforms a wide variety of functions essential for life5
8345213599Describe the function of the gallbladderstores and concentrates bile, fat in the small intestine stimulates the production of the hormone cholecystokinin which causes the gallbladder to contract and release bile6
8345213600Describe the function of the pancreasregulates blood glucose levels through secretion of the hormones, insulin and glucagon into the blood secretes digestive enzyme7
8345213601Describe catabolismthe breaking down of body compounds to release energy8
8345213602What are 4 units the body can break down for energy and use to build body compounds?glucose, fatty acids, glycerol, amino acids9
8345213603Why do hiccups occur?the muscle at the base of the lungs spasms (diaphragm)10
8345213604What are some treatments to hiccups?hold your breath, drink cold water quickly, drink upside-down, teaspoon of honey11
8345213605Why does gas/flatulence occur?way of getting rid of air swallowed, some foods cause gas because we cannot break them down12
8345213606Why does constipation occur?occurs when the colon absorbs too much water or if the muscle contractions are slow moving, stools can become hard or dry13
8345213607What are some treatments for constipation?most is temporary, but laxatives can help14
8345213608When do hemorrhoids occur?occur straining to have a bowel movement15
8345213609What are some treatments for hemorrhoids?treatments include tub baths in warm water for 10 minutes several times a day, or hemorrhoidal cream16
8345213610How do changes in our present-day supply increase the risk for chronic disease?we want fast food but our gene pool wants the lifestyle of the food of the ancient times17
8345213611What does the term functional food mean?foods that provide health benefits beyond basic nutrition due to physiological active components which may or may not have been manipulated or modified to enhance their activity18
8345213612Identify 3 functional foodssoy, broccoli, flaxseed19
8345280103Trace the order in which the bagel will move through the organs of the G,I TracyMouth, stomach, small intestine, large intestine20
8509151465CellsThe smallest units in which independent life can exist. All living things are single cells or organisms21
8509151466Essential nutrientsCompounds that must be obtained from food because the body cannot produce them or can't produce enough to meet physiological needs22
8509151467HypothalamusA part of the brain that senses a verity of conditions in the blood, such as a temperature, salt content, glucose content and others, signals other parts of the brain or body to change those conditions when necessary23
8509151468MouthGlands in the base of the tongue secrete a fat digesting enzyme known as lingual lipase. Some hard fats begin to melt as they reach body temperature24
8509151469StomachStomach acid works to uncoil protein strands and activate stomach enzymes. Enzymes break the strands into smaller fragments. Vitamin B12 requires intrinsic factor produced by the stomach in order to be absorbed25
8509151470PeristalsisThe wavelike squeezing motions of the stomach and intestines that digestive tract26
8509151471PylorusMuscle that regulates the opening of the bottom on the stomach27
8509151472EmulsifierA compound with both water soluble and fat soluble portions that can attract lipids into water to form an emulsion28
8509151473BileA compound mad from cholesterol by the liver, stored in the gallbladder, and secreted into the small intestine. It emulsifies lipids to ready them for enzymatic digestion29
8509151474HormoneA chemical messenger, secreted by one organ -a gland- in response to a condition in the body, that acts on another organ or organs to change that condition30
8509315876BicarbonateA chemical that neutralizes acid, a secretion of the pancreas31
8509315877EnzymeA protein catalyst. A catalyst is a compound that facilitated -speeds up the rate of- a chemical reaction without itself being altered in the process32
8509315878LymphA fluid outside the circulatory system that bathes the cells; derived from the blood by being pressed through the capillary walls; similar to the blood in composition but without red blood cells33
8509315879VilliFingerlike projections of the sheet of cells that line the GI tract; the villi makes the surface area much greater than it would otherwise be -singular; villus-34
8509315880MicrovilliTint hairlike projections on each cell of the intestinal tract lining that can trap nutrient partials and translocate them into the cells -singular; microvillus-35
8509315881Small intestinesThe organ of digestion and absorption36
8509315882Large intestineIs the organ that eliminates the body's waste37
8509315883LiverThe large, lobed organ that lies under the ribs and filters the blood, removing, processing and readying for redistribution many of its materials38
8509315884PancreasA gland that secretes the endocrine hormone insulin and produces the exocrine secretions that aid in digestion in the small intestine39
8509315885EndocrineA term to describe a gland secreting or a hormone being secreted into the blood40
8509315886InsulinA hormone from the pancreas that helps glucose get into cells41
8509315887ExocrineDescribes glands that secrete chemical messengers through a duct into a body cavity or onto the surface of the skin; exo means out42
8509315888CapillariesMinute, weblike blood vessels that connect arteries to veins and permit transfer of materials between blood and tissues43
8509315889VeinsBlood vessels that carry used blood from the tissues back to the heart44
8509315890When the body is depending solely on liver glycogen,the supply is used up within 3-6 hours45
8509315891The third energy nutrient protein isHeld in an available pool -amino acids- in the liver and blood, that is rather rapidly depleted during protein deficiency conditions46
8509315892The breakdown of body compounds is know as?Catabolism47
8509315893GlycogenCan be broken down to glucose, triglycerides to fatty acids and glycerol, and protein to amino acids48
8509315894AnabolismIs a process where glucose, aminos, glycerol, and fatty acids are used to build the body compounds49
8509315895ChylomicronA type of lipoprotein that transport newly digested fat - mostly triglyceride - from the intestine through lymph and blood50
8509315896LipoproteinsClusters of lipids associated with proteins that serve as transport vehicles for lipids in the blood and lymph51
8509315897MetabolismTotal of all chemical reactions that go on in living cells52
8509315898Energy metabolismAll reactions by which the body obtains and expands the energy from food or body stores53
