The linea alba is a fibrous structure that runs down the midline of the abdomen in humans and other vertebrates. It receives the attachments of the oblique and transverse abdominal muscles.
Which organ cleans the blood coming from the digestive organs?
In general by the reticuloendothelial system. primarily in the spleen and the liver kidney. however C02 is expelled through lungs and thus blood is 'cleaned' there too.
Why are the intestines so good at absorbing food molecules?
The small intestine has many villi, small projections into the lumen of the small intestine. These villi increase the surface area of the small intestine, and increase the funcitonal area for the absorbtion of nutrients.
In which organ is digestion completed for carbohydrates?
Technically the digestion of Carbohydrates is 'partly' completed in the MOUTH because Silva cotains Amylase (which breaks down Carbohydrates into compounds of sugars like Maltose for example) which allows the STOMACH to complete the digestive process with various different enzymes from the Pancreas and hydrochloric acid.
Therefore the answer when Carbs are 'completely' digested is in the STOMACH.
Isn't it in the rectum? Im confused!
carbs enter the duodenum in the partly digested form of dextrins and maltose. then they are further broken down into absorbable substances by the intestinal enzymes (maltase, sucrase, and lactase). so digestion in really completed in the small intestine... not the stomach.
What is the role of the digestive system in maintaining humans as functioning organisms?
The excretory and respiratory system do, in fact, work together. The excretory system is in charge of excreting waste products. Carbon-dioxide is a waste product which the lungs, a part of the respiratory system, excrete.
In digestion what is the function of the eosophagus?
The esophagus is the muscular tube connecting your mouth to your stomach. The muscles are a special type, smooth muscle tissue which contracts and relaxs without conscious thought. The movement is controlled by nerve tissues ad the contractions move the food along.
Define segmentation as in digestive system?
Segmentation in the digestive tract mixes food with digestive juices and increases the rate of absorption by repeatedly moving different parts of the food mass over the intestinal wall.
The difference between the digestive system or a cat and the digestive system of a human?
Answer:
None of my Cat books are closely available, but note these traits.
My son's cat Gertie, only drinks from his toilet, and randomly eats wild mice we think. Plus when she was a kitten last year ate Japanese Beetles whole as well as crickets! She is very healthy and this diet is by choice not convenience. She is indoors around 14 hours daily and also has upgrade dry food and nice cat treats. She has never been sick yet and is 18 months old in human years. My own male cat Houston, also adds strange supplements to his regular catfood and Fancy Feast Delicacies. He eats any type of chameleon, almost whole, small snakes, small frogs, dragonflies, chlorine pool water (sanitized water), pond water, large insects and rarely- birds. To offset this somewhat treacherous diet, he adores dairy foods like yogurt. skim milk, etc. and leads a pampered virtually safe life indoors- around 20 hours a day or more. Again,
other undesirable foods ingested are by his choice-not ours-and he is the healthiest cat we have ever owned. If a cat is outdoors as much as Gertie or even like Houston, they should have about every Vaccination that exists, to offset the dangers that lurk in all neighborhoods - you never know what is hiding outside nowadays - rabies, feline leukemia, etc. Also, we own a very large female cat who is not allowed anywhere outdoors except an occasional front porch sit with mom. To supplement her diet, she is allowed to eat real growing catnip, grassy type porch plants, celery leaves, banana, pea soup, pizza sauce and loves to sniff strawberrries. She does not tolerate any milk
products since they seem to be unhealthy believe it or not, on most cats tummies. All three cats are very healthy-rating them by most healthy is 1) Houston (10 yrs old)
2) Gertie (1 1/2 yrs) 3) Macy ( 12 yrs). Unsure if Macy is just showing her age now, but if diet were measured it sure is interesting!
Answer:
A cat's digestive system and a human's digestive system differ greatly. Human beings are omnivores, so have evolved to gain nutrients from both meat and plant matter. Cats on the other hand, are obligate carnivores. This means they only get their nutrients from meat including organs and bone.
There are many amino acids and vitamins raw meat supply that cats cannot synthesise in their bodies. The best-known of all is Taurine. A cat that doesn't get enough taurine for instance will eventually develop heart and eye problems.
Humans get a lot of essential vitamins and other nutrients from plants such as vegetables and fruits. Cats do not need plant matter at all. In fact, cats actually have trouble digesting foods high in carbohydrate such as grains, which are sadly abundant in many brands and types of cat food. That being said, cats that have access to outside will readily eat grass on occasion. This isn't for nutritional reasons, but to help aid digestion. Grass helps a cat regurgitate hairballs or other undesired food that the cat has ingested.
However, some cats do like to nibble on raw vegetables on occasion. There isn't a clear reason for this, but it could be that they like the taste, or it contains some nutrient that they are lacking.
Because of a human's and cat's digestive systems, a cat's system is perfectly designed to handle raw meat. It is fast and efficient at breaking down meat and bone - something humans have difficulty doing with our broad diet. Because of this super fast system, a healthy cat will unlikely become sick from potential bacteria found in meat such as salmonella; food does not stay in the tract long enough for bacteria to multiply to harmful levels. Humans on the other hand, have much slower digestive systems which makes us more susceptible to harmful bacteria in food - which is why we cook out meat as it destroys any bacteria (but also kills nutrients that cats need), therefore making it easier to digest.
The mechanical and chemical receptors that control digestive activity are located?
In the walls of the tract organs
Is the esophagus the first section of the digestive tract?
No, the oral cavity is the first part of the digestive system.
How is an animals digestive system similar and different to another animals?
It is different from most animals, but it is very similar to a pigs digestive system. Yes, a pig. Some would imagine it would be most like an ape's, but it's not.
What happens when body rejects food through feeding tube?
Sh*ts his pant mybe.Scentist just have recently found out this happens to a lucky 1 out of a 100 people.
-------
My sister was unfortunate enough to have this happen to her. She suffered from delayed gastric emptying -- basically her digestive system didn't move food through. She went through virtually all formulas on the market and ended up going to IV nutrition. If the question is looking for what you can do to address intolerance, here's some ideas:
If the problem is an emptying problem like hers or a malabsorption problem, they have "elemental" formulas that are already partially broken down, so it's easier for the body to digest. So, that is one option. Another option is adding things to the formula or taking medications to address whatever issues the formula is causing. So, if it's constipation for example, there's powdered fiber you can add. If the problem is an intolerance to the ingredients, there's a great formula called Compleat that contains mostly real food. Some people also actually puree and make their own tube food. Obviously, it's important to consult your doctor before trying anything new and to regularly check up on the patient's nutritional health.
If none of those options work and no formula or supplement combinations work, there is an option of IV nutrition. You can actually get full nutrition through your veins. It's not ideal and there are risks and side effects, but it can be a relief to someone who's been miserable on tube feedings.
If the question was just looking for what happens to the body when it "rejects" the formula, it's generally vomiting, diahhrea, and/or severe bloating. Other symptoms might include constipation and nausea.
Bile salts are responsible for the digestion and absorption of?
Bile is produced in the liver and helps to digest fat in the human body. Once produced, bile is stored in the gallbladder and is discharged into the duodenum when a person eats.
What is part of the gastrointestinal system but not the gastrointestinal tract?
I think you are looking for liver and pancreas, these are accessory digestive organs that produce enzymes and emulsifiers that are secreted into the digestive tract.
What makes the digestive system function?
Mostly hormones, enzymes, buffering agents, emulsifiers, and other chemical. And then also autonomic tonic and peristaltic muscle muscle activity. The special senses like sight, smell, taste, and touch also play a role in preparing the digestive system to function properly.
Where is mucus secreted in the alimentary canal?
Mucus is secreted so that peristalsis can occur and can slide easily down you throat.
How long it takes for food intake to pass through the human digestive system?
Any where from 6 hours to 3 days. Vegetarian diets are more quickly digested than carnivorous ones. You can test your own digestion time by eating something that you passes through like corn, but be sure to not have eaten that food for a few days to ensure the food coming out was the same that went in.
In which organ is most food digested and absorbed during digestion?
I will have to say the digestive system break down the most food because it contains enzymes which breaks down substrates and speed up chemical reactions and allows it to flow through your blood stream, amalyst, catalyst, enzyme pepsin, and others.
The stomach
