What contains digestive enzymes that help clean up the cell?

The lysosomes contains digestive enzymes that help clean up the cell. It also helps in breaking down the complex compounds that come into the cell.

Do echinoderms have a digestive system?

yes

The digestive system of annelids consists of an unsegmented gut that runs through the middle of the body from the mouth, located on the underside of the head, to the anus, which is on the pygidium.

Is the kidneys organs of the digestive system?

kidneys get rid of the toxins from the blood that may have come from the food your body has digested. kidneys also help to make urine, keep your bones healthy, make red blood cells and also help to remove waste and extra fluid from your body.

How is the earthworm's digestive system different from a human's?

Worms have a very special digestive system. Instead of having a small and large intestine, worms have only one. And it is called an intestine. They also have organs known as the crop and gizzard, which breaks down the food, since the only thing that worms do is eat. Those are the only things that worms have different than humans

What two structures add digestive juices for the breakdown of fat?

The gallbladder and pancreas add digestive juices for the breakdown of fat.

What is the difference between ingestion and digestion and egestion?

Ingestion is the absorption of materials or nutrients by a cell or organism. In humans, ingestion occurs in the mouth. A person ingests food and drink by chewing and/or swallowing After someone ingests something, the substance begins to work its way through the gastrointestinal tract in the process called digestion.

Digestion is the process of breaking down food into smaller, soluble components that can be absorbed into the bloodstream. It is a form of catabolism - breaking food molecules down. Without digestion, the body cannot use the nutrients in food.

Egestion is the discharge of undigested material or faeces from the digestive tract via the anus. Egestion refers solely to indigestible matter which is never absorbed into the cells -

it sould not to be confused with excretion, which is the discharge of waste formed by chemical reactions in the body, such as sweat and urine.

Does fat slow down digestion?

Not, really no

~This previous answer is not entirely correct. Actually your answer depends on the nature of the question. If you're asking whether the digestion of fat slows down the digestion of other foods such as carbohydrates, proteins etc. in the gastric (stomach) phase, then the answer is no. Although it can delay the digestion of other nutrients in the small intestine, the secretion of lipase does not prevent or delay the secretion of amylase etc. nor does the presence of lipase inhibit other digestive enzymes.

However, once fats have entered the small intenstine, it actually can cause a backlog, which is referred to as a slowed digestive transit. This backlog can cause constipation, and other related problems. Because it takes quite a lot of energy to digest fats, blood becomes concentrated in this area, contributing to an overall feeling of tiredness, and a retention of food in the stomach because the intenstine is too full (bloating).

However, it should be pointed out that this is an extreme example. Generally speaking, you should not eat such a high concentration of fat as to cause this problem. A regular person eating a normal diet would consume fat in a ratio with other nutrients that would allow them to all move freely through the gut.

Why is it vital for living things such as frogs to digest food?

It is NOT vital for frogs, (or other animals) to eat living creatures. What is vital is oxygen and water. Without those things, they will die for certain. But, the living creatures that they consume as food, provides them with an almost instant stimulation of false energy. I say false because it over time, destroys their bodies from the inside out,(to consume creatures). The stimulation comes in the form of the toxic byproducts that are produced in the bodies as the digestion takes place, much the same way a drug might work in a human body when taken for the same purpose: it may provide a false, instant energy, but essentially it does NOT vitalize the human body at all; it destroys its vitality. This is why frogs eventually die.

How does cow's digestive system is similar to human?

You are not going to get that "long answer." A cow's and human's digestive system is NOT the same, I don't care how you try to go about it. Yes they are similar in function, by the fact that they both break down and digest food or feed to more manageable and smaller molecules to be absorbed into the body via blood stream to the zillion cells that are in the body, but they are not the same in what is digested and the whole processes that set a cow's digestive system apart from that of a human's.

How long it take the average person to digest one drink?

Alcohol will remain in the body anywhere from 1 to 6 hours depending on the amount of alcohol ingested. Alcohol metabolizes at a rate of 0.15 BAC per hour.

What are the organs of the digestive system in a animal?

That would be pretty much any animal that's big enough for you to see with your naked eye.

What is the function of gallbladder in a turtle?

The function of gallbladder in a turtle is to aid in digestion. It secretes digestive juices that help the turtle make use of the food that it eats.

What is the enzyme called in your stomach?

There are many digestive juices in your stomach, the main ones are hydrochloric acid (HCl) and peptin. Peptin is an enzyme that digests proteins and HCl is an acid that dissolves most everything else. The stomach can only digest proteins. Carbohydrates and lipids are digested in the small intestine, where most digestion takes place.

Where does the majority of protein digestion happen?

Protein mostly gets digested in the stomach, in the stomach is where all the nutrients get sifted like out.

What do most organisms use to break down food?

Organisms have cells. Inside the cells, there is a organelle called the lysosome. The lysosome breaks down and digests food. Or your digestive system can digest food.

Which nutrient is chemically digested in the esophagus?

The answer would probably be starch since this is the only nutrient that start to be digested in mouth and along the esophagus to the stomach.

More accurate to say 'none', for although saliva does start digestion that is added in the mouth and the oesophagus is simply the conduit from mouth to stomach.

Can tea aid digestion?

Yes, it's SO much better when you add something to it, like liquid Coffeemate, half and half or milk. It lessens the tannic acids in the tea. Also make the tea less strong. Only steep it for two minutes.

In which part of the digestive system does food get absorbed?

This is the simplest question all week. The ileum (i-li-um). The food we eat is absorb in the ileum, or the small intestine.

Another View

Contrary to what was said above, most digested molecules of food, as well as water and minerals, are absorbed through the length of the small intestine, not just the ileum. The ileum is the final section of small intestine and absorbs only vitamin B12 and bile salts. The small intestine is made up of the jejunum and ileum. The mucosa of the small intestine contains many folds that are covered with tiny hair like projections called villi. In turn, the villi are covered with microscopic projections called microvilli. These structures create a vast surface area through which nutrients can be absorbed. Specialized cells allow absorbed materials to cross the mucosa into the blood, where they are carried off in the bloodstream to other parts of the body for storage or further chemical change. This part of the process changes with different types of nutrients.

What system sends nutrients to all the body's cells?

The circulatory system works with the digestive system and respiratory system to bring nutrients to all body cells.

How long does it take to digest caffeine?

When you take in caffeine, these receptors get blocked, your heart rate speeds up, and you get a jolt of heightened alertness - which might be what you want so you can keep going, but meanwhile your brain is looking to sleep, not caffeine, for restoration.

Does it take 7 seconds for food to reach the stomach from the mouth?

The simple answer to this is "NO". After a meal depending on the type of meal( whether carbohydrate, fats or protein) the stomach undergoes a process of churning and mixing of the food with digestive juices. This enables easy absorption. 6 seconds is however too. Short for this process to occur.

It takes approximately 2 hours for gastric emptying.

Carbohydrate meals leaves faster than fatty meals which leaves faster than protein-rich meals.

How is blood circulation related to digestive system?

Diet and lifestyle are closely related to the digestive system in the sense that a poor diet and lifestyle slows down your digestive system and prevents it from working at its best.
