What is the main site of all digestion in the body?
The small intestines.
Nutrients from the small intestine leave through the what? What
Mucosal cell layer
Nutrient from the small intestine move to what systems?
Lymphatic or circulatory
What does the pancreas do?
It secretes digestive enzymes and bicarbonate ions into the small intestine
What is bile?
A substance made in the liver and stored in the gallbladder.y aids fat digestion.
The process that helps pass nutrients through the mucosal cell.
Simple diffusion.
Nutrient that need help use carrier molecules in a process called?
Facilitated diffusion.
Things that were not absorbed in the small intestine move where?
To the large intestine, colon then rectum.
What is active transport?
Requires entertaining and carrier to move nutrient.
What is the process of fat through absorption and digestion?
Lipid, bile turns into Miceles in small intestines, then to fatty acids and monoglycerides. , through microvilli to triglycerides chrlomicribs the exoctosios to the lymph sys
The first step in the fat to atp process is called what and what does it do?
Beta oxidation and the carbon chain of fatty acids is broken ldown into 2 carbon units the for a high energy electron.
Fat is stored in VlDL and secreted people with high VLDL tend to have a higher risk of?
Cardiovascular disease
HDL does what?
Reverse cholesterol transport.
LDL does what?
Transport cholesterol tissues to.
The livers role in digestion and absorption of fat
Makes bile
The pancreas is role in digesting the macro nutrients
Produces enzymes to digest
What is the role of the gallbladder
Stores bile
Large intestines roll
Absorb water and some vitamins and minerals home to intestinal bacteria
Enzymes that break down certain amino acids are filmed and watch Oregon
Pancreas
What is the role of pepsin
Briggs proteins into polypeptides and amino acids found and stomach
What is the role of trips in
Found in pancreas and it breaks down proteins and polypeptides into shorter polypeptides
What is the role of chymotrypsin
Breaks proteins and polypeptides into shorter polypeptides
What are anti-bodies
Proteins produced by cells of the immune system that destroys in active foreign substances in the body
The first immune response is called. But also in golf harmful organisms and breaks them down
PHAGOCYTES
