Digestive system 👄 Flashcards
Two products of complete lipid digestion of lipase
Fatty acids,
Glycerol
Location in digestive system where lipase digests lipids
Duodenum
Optimum PH for digestion of lipids in the duodenum
7-9
Describe action of bile salts on lipid
Emulsifies
Name structure inside each villus that absorbs the products of lipid digestion
Lacteal
Explain term digestion
The breakdown of food
Two reasons why is digestion necessary in humans
For the absorption of nutrients and for the transportation of food and nutritions
Name given to the removal of un digested waste from the human body
Egestion
Precise location where villi are most abundant
Duodenum/ small intestine
Main function of villi
To increase surface area for the absorption of nutrients
Function of lacteal
Digests fatty acids
Blood vessel that carries the digested nutrients
Hepatic portal vein
To what organ are Digested nutrients first transported
Liver
Name and explain the process of how food is moved along the alimentary canal
Peristalsis,
Involuntary wavelike movement that pushes food along the alimentary canal
Enzyme that digest Dietary protein
Pepsin
Where is pepsin active and produced
Stomach
Products formed by complete digestion of a protein molecule
Amino acids
Heterotrophic
Eats other organisms
Omnivorous
Eats both plants and animals
What is lipase
Enzyme that digests lipids
Dental formula
I 2/2 C 1/1 PM 2/2 M3/3
Two functions of large intestine
Absorption of water, absorb vitamins
Two beneficial functions of the bacteria that live in the digestive tract
Production of vitamins, benefits immune system
Two glands that pas their se creations into the small intestine
Liver,
Pancreas
What are symbiotic bacteria
Bacteria living in or on another organism involving benefit
Where in the human alimentary canal is water most absorbed
Large intestine
Distinguish between chemical and physical digestion
Physical is the mechanical breakdown of food by chewing,
Chemical is the breakdown of food because of the action of acid
One digestive function of pancreas
Produces Enzymes
Substance transported to liver by blood in the hepatic portal vein
Co2
Blood vessel that brings oxygenated blood to the liver
Hepatic artery
Where is the liver in relation to the stomach
Above
Where is bile stored after it’s been made in the liver
Gall bladder
Two functions of the liver
Storage of vitamins, heat generation
Name a process involved in the passage of products of digestion into the blood
Passive transport/ diffusion
Why low PH important in stomach
Kills germs, optimal PH for enzymes
Enzyme involved in the digestion of fat
Lipase
Role of bile in fat digestion
Emulsification
