What happens to your body when you eat a nutritious dinner

Subject: Biology , Human

We can eat as much as you like and get lots of energy, but what use this energy to? Why should you eat after a workout? And why one gets tired if you do not eat a proper breakfast? We all know that you chew with your teeth, swallow and then it will look like stool, but how does one dinner through the whole body?
All the energy we consume goes to the use of muscles, breathing, and so klart- digestion. It also goes to training, and to build the muscles needed protein, it is found in food.
You get tired if you have not eaten a proper breakfast because you have not been taking any energy and we ate before we put ourselves have been spent. The rest you can read about below.

Mouth: Used but the help of the teeth in order to make the food we eat into smaller parts so that it can then be mixed with saliva. This is the first division. For that we should not bring down the dangerous substance hydrogen peroxide, which is corrosive to the large quantity, we Catalase in saliva that breaks down hydrogen peroxide into water and oxygen. With the help of saliva starts a chemical degradation, saliva helps so that the food will be easier to swallow. When the chemical decomposition is finished starch in the food has been maltose, a type of sugar that is part of polysaccharides. When this is done, we will then swallow and we do this by using the tongue pushes the food toward the throat. The food goes down through the gullet (esophagus) that uses the muscles that contract and for the food down to the stomach which is the next station, the 25cm road takes a minute and is divided into three different parts.

Stomach: The food goes through the cardia of the stomach. There, mashed and blended food with gastric juice as inner holding hydrochloric acid and enzymes. The enzyme in this case is pepsin. The enzymes parts of food proteins into smaller molecules until everything has become mush. Is there not enough hydrochloric acid as the stomach is upset. This is usually due to excessive intake of coffee, alcohol, cigarettes or to be stressed. Causes that lead to gastric mucosa can not make hydrochloric acid, adverse effects include Hypertension. Mashing of the food takes about 3 hours and before it goes out to the intestines as food goes through the pylorus for that not everything will go directly into the digestive tract, it brought out in parts.

Liver: The body's reserves and purification tank, making some subjects so that they do not harm the body such as alcohol or ammonia. Two substances that are made and then brought the out of the body while urine.
The liver cleanses the blood from unwanted substances by transporting them to the intestines along with the bile. The topics included with the poo out of our body. Examples of an undesirable substance is gallfärgen, the blidas of old red cells as degraded. It is gallfärgen giving Poo its brown color.

The kidneys: Here, blood is purified, it goes into the kidney via the renal artery and then slid it to blodkärlsnystanet that purification is through. However, do not work the vessel out of the kidneys as fast as all the liquid flowing past and the blood cells and protein stop for a while.
All the water and substances needed drawn into the renal duct walls and back to the blood. The remains were just passing through and changes to be urine.

Now we come to the intestinal tract which is divided into two main parts, small intestine and colon. The intestines have the task of clearing away all food that do not contain any närningsämnen body needs. But first comes the duodenum.

Duodenum: The food goes from the pylorus to the duodenum. There, the bile, pancreatic juice and its enzymes and has a pH of 8.8 so that it becomes a neutral environment for the acids to not corrode the intestinal walls. All enzymes share different things, Lipase parts lipids (fats) and makes it Minde parts and Protein kinase breaks down protein into amino acid. The duodenum is about as long as the esophagus, about 25cm long.

Small intestine: is the longest tarmdel we have with its five meters. When muscles work, sitting around the gut, too full. When you're dead becomes the intestine up to ten meters because the body does not work and all the muscles relax.
When the food comes to the small intestine mixes with digestive juices that make everything easy flowing and final degradation occurs.
Carbohydrates become glucose used as energy and the fat turns into fatty acids.
Villi on the inside of the intestine and are there to take up the nutrients and vitamins are the foods you eat and your body breaking down. Villi sitting on mucous tissue, which in turn covers the entire small intestine walls.

Cecum: A 10cm long part of the intestines which sits between the small intestine and colon as a kind of tray. Is also a body that we can live without, as it finds no major feature for us humans.

The colon: All water that the food brought with them on their journey are now listed. The remaining parts of the food that the body is not able to take up somehow become when a compressed mass. This mass (also called poop) then end up in the rectum, where it is emptied when you go to the bathroom.
This whole process took about a day. But we know that food does not just go straight through the body and then out, it breaks the bottom and become nutrients, vitamins and minerals. Why do we need them?

First and foremost, we need oxygen to all be able to walk around in our body. Blood retrieves oxygen and leaves carbon dioxide, for this to work, we have small clusters in the lungs called alveoli. They have a diameter of 0.1 mm and has a small network of itself, the network consists of capillaries that are composed of flat cells. The blood contained in the capillaries inside keeps hemoglobin (the substance that gives blood its red color, the inner holding iron) and it takes up and leaving oxygen, in this case the download.
The oxygen-rich blood returns to the heart from the lungs, first through the left atrium, then sails flap and into the left ventricle where the blood is compressed and the blood is transported out through the flap received during the same process is automatically opened. The heart is entrusted to all the body's strongest muscle.
After this little trip goes all the blood into the aorta, also called the aorta. This huge vein parts after a bit up and becomes arteries. Although the arteries become smaller and smaller, and finally becomes to Capillaries composed of a bearing plate cells, these transports the blood to all tissues.

Proteins: As found in pasta, meat and milk, is used to build muscle mass composed of cells. Are also a part of hemoglobin and hormones. The subject is made up of amino acids and is found in several different combinations, amino acids stuck together until the food is shared in the stomach and intestines. It is in the capillaries around the intestine as the blood picks up amino acids and those distributed to various body parts.
Protein is also a part of:
Enzymes that we used the breakdown of starches
Our nails and skin

Carbohydrates: Is the name used to define all sugars, how they look; single or several combined.
Single molecules, for example, glucose and fructose, because they do not have to be shared by the enzymes on its way through the intestines so they go straight down and into the blood. You get quick energy.
Combined molecules such as starches found in seeds and potatoes, and cellulose (found in plant walls consisting of cells). Cellulose can not be broken down, but it has starches so that they become single molecules, this takes longer and therefore we must not energy right after we ate. If you eat too many carbohydrates than your body can consume as energy becomes a storage form of fat.

Fat: Is it that the body uses as energy storage, fat is much more energetic than what carbohydrates are.
Do you feel that you start to get a little around the stomach, it is not necessarily so that eating too much, but still have higher RDI (recommended daily intake) than is needed and it is converted into fat that settles around the intestines. One should not forget that the fat used in our palms to cushion shocks and heat in the body when it is cold. The fat is an energy saving.
Everyone knows that margarine, butter and cooking oil inside keeps fat but there are so many other forms. Animal fat is one of the forms and the fat in animals, eg salmon and pig. But there is a difference between fat from pork and fat from fish because the fat from a pig can calcify our blood vessels and fat from fish prevent this.

Minerals: Needed to keep our body on the legs. The most common minerals are iron (much of hemoglobin), Sodium (adjust our body's fluid balance and blood pressure).

Vitamins: Some of them are part of the enzymes. Should not in itself the right amount / eat a sufficiently varied food is common, especially in countries with poverty, that you get diseases.
It is also important to know that all vitamins are not positive; you eat the wrong amount (ie too much) of A, D, E and K, the liver damage because these are not released with the Pussycat. B and C, you can eat as much of anything. Vitamins are found in vegetables, fat, coarse bread and supplements in the form of tablets.

Water: If you become ill and can not get into the food you have to drink water, the same thing in diseases such as diarrhea and stomach problems (diseases that are liquid).
2/3 of our bodies are filled with water sitting together with cells.

Food circle A tool that is easy to use in the selection of food. You should eat something from each part every day to get a really varied, good and nutritious diet.

    Hey, you've written a great upsats and I will use part of it when I should write my to hemprovet. But "The oxygen-rich blood returns to the heart from the lungs" that you need done a carelessness wrong for it is well oxygenated blood leaves the lungs?
