The majority of fat digestion happens once it reaches the small intestine. This is also where the majority of nutrients are absorbed. Your pancreas produces enzymes that break down fat.Human digestive system Human digestive system Fats: Almost all dietary fat is stored as triglycerides. Solubility in water is necessary in order for fat to be transferred from the lumen of the intestine to the absorptive cells.
Digestion of fat begins in the mouth where the food you chew is mixed with a small amount of lingual lipase that is found in your saliva. Lingual lipase is a digestive enzyme that breaks fatty acids apart from triglycerides. Once you swallow your food, digestion continues in the stomach. The food you eat is squished and mixed with stomach enzymes.
Explain the structure, function, and location of sphincters. structure: highly specialized circular muscle, permanent structure Complete the digestion of carbohydrate, protein, & fat Absorption of nutrients and other food components and reabsorption of digestive secretions.The pharynx (throat) is the transition area from the mouth to the esophagus. From the pharynx there are two paths that the food bolus can take; 1) the wrong path, which is down the windpipe into the lungs, or 2) the correct path into the esophagus and then the stomach.The act of swallowing is a complex process that closes the windpipe (to protect our lungs) and moves food into the esophagus.
Saturated fat, or animal fat, is composed of a glycerol backbone with three fully saturated fatty acids attached. Saturated refers to all the carbons in the backbone being sp 3 hybridized, with two hydrogen atoms covalently bonded per carbon. This class of fats have higher viscosity and energy content than their unsaturated cousins.A correct function of the human stomach is storage of food and mixing with digestive fluids to allow chemical digestion. In order for fats to be digested into fatty acids and glycerol efficiently pancreatic juice must be secreted and BILE must be present.
chains, the structure is called a protein (it is also called a polypeptide because it contains many peptide bonds). Glycerol 3 Fatty Acids (where R represents a long C-C-C chain) Fat (triglyceride) (where R, R’ & R” may or may not be the same) General Structure of an Amino Acid A Peptide Bond.The digestive system breaks down ingested food, prepares it for uptake by the body’s cells, provides body water, and eliminates wastes.
This system consists of the gastrointestinal tract and accessory organs of digestion: the liver, gallbladder, and exocrine pancreas.Lipid Lipid Digestion of dietary fatty acids: The main source of fatty acids in the diet is triglycerides, generically called fats. In humans, fat constitutes an important part of the diet, and in some countries it can contribute as much as 45 percent of energy intake.
Triglycerides consist of three fatty acid molecules, each linked by an ester bond to one of the three OH groups of a.The function of each part of the digestive system. The digestive system starts from mouth to the anus. The important parts of the digestive systems are mouth, teeth, tongue, oesophagus, liver, gall bladder, pancreas, stomach, small intestine, large intestine (colon), rectum and anus.The major functions of the liver include: Bile production: Bile helps the small intestine break down and absorb fats, cholesterol, and some vitamins.
Bile consists of bile salts, cholesterol.Digestion is the breakdown of carbohydrates, proteins and fats into small soluble substances to be absorbed into the blood. Amylase, proteases and lipases are enzymes that are important in.Table of Contents Introduction Part A Explain the function of each part of the digestive system identified in the diagram above.

Can anyone add a little more detail of how to chylomicrons go to skeletal and adipose tissue from the thoracic duct?
Actually I raised this question because of the fact that the venous blood later go to the heart and then to lungs and how does the fats gets into those above mentioned tissues.
Thanks
No idea what people mean about your voice… Seems like people can never be happy. Thanks for the video! I needed this.
I am in the middle of viewing this video, and am thinking, “I really like this instructor.” She explains everything clearly and concisely. I am also thinking, “Hmm, I really like the voice.” I quickly check out some comments, and see that some have the opposite opinion. I am a guy, so I don’t know, I really like this instructor’s voice. Soothing, relaxing, but clear and bright at the same time. It’s true that the voice alone can tell us whether we will like a person or not. For example, for me, when it comes to radio station hosts, generally speaking, the Jazz station hosts have the most pleasant and interesting voices.
Thanks mate for such a nice experience and explaination cheers mate ��
He said the doo-doo hole! lmao I love how laid back these videos are. It makes learning this (sometimes boring) material so much more fun and easy.
Great video. Except Lingual Lipase is only found in animals. It is not found in humans. What’s found in humans oral cavities is actually gastric lipase (coming from the stomach).
When ever i want to understand a topic i search for ur channel first ��. You make it interesting and simple to understand. Thank u so much sir��
XXI education arises.
I suffered my engineer bachelor with those dull classes, that can kill anyones attention.
Under this format, visual attractive and appealing, quick and fluid, strong concepts, etc…
This lead to expose the truth difficulty of the subject that is actually very low when you have all language elements already present in your memory.
I’m really happy after enjoyed this video, I will stick to Khan as much as I can.
Great process summary. I have a question. When lecithin or Phosphatidylcholine is used as a carrier to encapsulate a nutrient, is the release of this nutrient triggered in the first encounter with the lipase molecule or in the second encounter with the lipoprotein lipase in the blood?
Her voice is hot. Other videos like these are narrated by Indian guys with thick accents.
great video summed up above half of my digestion of lipid notes, haha. From looking at the cap i first thought you were at an outdoor basketball court.
your voice is so lovely! thanks!!!!! this was very clear and your explanation was very genuine
These videos are amazing! They present the information with the perfect level of complexity and depth, and they are so incredibly thorough—they are an invaluable resource for me as a nutrition coach. And for the record, the narrator’s voice is lovely ��
Dear Sir, within 9 minutes you were able to gave detailed information. Even normal people can able to understand. Excellent teaching sir
wow, 45 minutes of reading condensed into 5 minutes (if watching 2x). Good job.
WTF people? Her voice is amazing. Go do something productive instead of bitching about stupid shit on YT.
I’d pay for you to spell “chessburger” 100 times. Really.
Great explanation as well, thanks!
Very clear, concise & extremely informative. Do you have similar lectures on carbohydrates and proteins?
very informative video… can you make a video on Short Chain Triglyceride, Medium-Chain Triglycerides, Long Chain Triglycerides, Mono-glycerides, di-glycerides, tri-glycerides, saturated, unsaturated fats etc… what is the difference between them….these terms look confusing…
Correct me if I’m wrong. But doesn’t shot free fatty acids go directly into the bloodstream on not into the lymph system?
Are Prostaglandins considered a Steroid because they also have hydrocarbon ring? If not, what are they classified as? (alkanes, esthers, amides) or (simple lipids, compound lipids, etc.)? Thanks. This vid was overall very helpful!
nice video, but what is the diffrence bw long chain and short chain FA in term of absorption?
This is the clearest and most coherent explanation of this process I have come across. My professor explained it terribly.
I don’t get the comments about her voice??? nothing wrong with her voice at all, sounds quite normal to me, go fuck off for yourselves making comments like that. Fantastic explanation, helped me a lot with exams.
Oh my god, i was stressing out so much for my digestive system test and you have eased my anxiety! Thank you so much for your help with the digestion of fats, carbs, and protein videos!!
Ive just subscribed and i look forward to exploring your channel more!
Is it true that diatry fat does not provide us with energy?? I recently had someone who claims to have studdied biochemistry, on another topic talk about how ketosis is dangerous and that the fats we all intake are oxidized and unable to be used.. he had this to say;
“The fat that gets converted to ketones all derive from glucose. We make our own triglycerides via consumption of various types of sugars or things that convert to glucose (starch, fructose, lactose, etc.). This is the only way we get fats, we make them dietary fats are useless, mostly either cooked, rancid, oxidized or all of the above in one meal
The human body is genetically predisposed to make all the so called nutrients it needs provided it is fueled (water, a carbohydrate, minerals, sunlight and oxygen). B12 is synthesized not just in the gut but elswhere through out the body a common misunderstanding. When u speak to “dietary fat” what is the molecule state? What condition is this molecule u and others hang their hat on. The fat molecule in a live cow say, is not at all the same after the cow dies, decay dynamics break it down. If the cow is rushed, soon after death to a freezer then decay dynamics are suspened. However, thawing out the meat will once again expose the molecules rendering them altered. Further, cooking will againg alter (destroy) the molecule. And then we have human digestion which seals the deal on this once intact molecule, in the live cow, no longer being intact. So when u speak to dietary fat tell us about the state of the molecule that matters a whole hell of a lot. A molecule altered in any way shape or form is useless (physics and chem 101) or not the same as it was before altered no longer with the same functions. Dietary fat in know way shape or form thus is providing any kind of fuel. The fat we make, from dietary sugars can do this, bit still the fat will end up as a ribose molecule once again (ATP) We cannot use dietary fats. They can pass right through us, rendered down further by digestive enzymes ending up in the toilet or harm us as rancid and oxidized fats and oils can do. Dietary sugars make human fats and any kind of fats in the body all have their origins in a ribose molecule including ketones. If any exogenous molecule is that stable and hardy, impervious to much criteria then it will pass on right through to the toilet like so much corn and or peanuts”
What is he talking about?
Amazing!!! Thank you for this illustration, it really helped clear out some doubts I had. Definitely subscribing��
Thank you for the clarity and fun way you present these topics
Thank you so much for your videos. They are a blessing to any student trying to pass nursing prerequisites. God bless you.
