The body breaks down nutrients from food and drink into carbohydrates, protein, fats, and vitamins, which are all necessary for the body to be able to function.

The mouth also contains saliva, which acts as a digestive juice.]]> 2017-06-02 04:18:48 UTC https://padlet.com/stenstrb/6s64xy6s5xho/wish/174920490 Esophagus stenstrb https://padlet.com/stenstrb/6s64xy6s5xho/wish/174920585 The esophagus allows us to swallow and intake food, and allows the food to have a direct pathway to our stomach. Once we begin swallowing, it becomes an  involuntary action  and proceeds under the control of the esophagus and brain. The lower esophageal sphincter, which is a ringlike muscle at the meeting point of the esophagus and stomach, is responsible for the passage of food and liquid between the esophagus and stomach. When food becomes closer to the closed sphincter, the muscle relaxes and lets the food enter the stomach.

The upper muscles of the stomach relax in order to let food in, and the lower muscles mix food and stomach acid together in order to digest the food, so that it can be utilized by the body. The stomach breaks down proteins.  It stores the swallowed food and liquid, mixes the food and liquid with the acid that it produces. It slowly empties the contents, which is  called chyme, into the small intestine.]]> 2017-06-02 22:20:40 UTC https://padlet.com/stenstrb/6s64xy6s5xho/wish/175036964 Small Intestine stenstrb https://padlet.com/stenstrb/6s64xy6s5xho/wish/175037098 The small intestine is composed of smooth muscle, which moves the food through its length while further breaking it down and digesting it.  The small intestine absorbs most of the nutrients, seeing as it's responsible for starches, proteins, and carbohydrates. The walls of the small intestine absorb the digested nutrients into the bloodstream. The blood delivers the nutrients to the rest of the body.]]> 2017-06-02 22:24:13 UTC https://padlet.com/stenstrb/6s64xy6s5xho/wish/175037098 Large Intestine/Rectum stenstrb https://padlet.com/stenstrb/6s64xy6s5xho/wish/175037202 The muscles of the small intestine push the waste products, including The walls of the small intestine absorb the digested nutrients into the bloodstream. The blood delivers the nutrients to the rest of the body, into the large intestine. The large intestine absorbs the water and any left over nutrients. It also changes the waste from liquid into stool. The rectum stores the stool until it is pushed out through the anus.

When we eat, the gallbladder pushes the bile through the bile duct. The bile ducts connect the gallbladder and liver to the small intestine. The bile mixes in with the fat in food. The bile acids dissolve fat into the watery contents of the intestine so that the other enzymes are able to digest the fat molecules.]]> 2017-06-02 22:30:36 UTC https://padlet.com/stenstrb/6s64xy6s5xho/wish/175037318 Liver stenstrb https://padlet.com/stenstrb/6s64xy6s5xho/wish/175037331 The liver is responsible for producing a digestive juice which is known as bile

It also controls smooth muscle, which is the main component of the digestive organs, and how food is moved through the system (via muscle contractions). Because digestion is controlled by both nervous and endocrine systems, both can impact how well our GI tract functions. It has been shown that stress can lead to problems with the stomach lining (leading to ulcers), and conditions such as IBS. In turn, the digestive system provides nutrients and hydration that allow the body and brain to function. ]]> 2017-06-02 22:43:58 UTC https://padlet.com/stenstrb/6s64xy6s5xho/wish/175037919 The Circulatory System stenstrb https://padlet.com/stenstrb/6s64xy6s5xho/wish/175038019 The basis of the relationship between the digestive system and the circulatory system comes from the fact that the digestive system requires about 30% of all cardiac output. This large amount of blood is needed for ongoing digestive functions. The digestive system requires blood to keep functioning properly, because it needs the nutrients found in the blood in order to repair cells and perform its job. Because the digestive system is always functioning, it requires large amounts of blood at all times. But, the circulatory system relies on the digestive system for those key nutrients. When the broken-down food enters the vascular small intestines, absorption occurs. Many vital substances, such as nutrients and minerals,  move from the food in the intestines into the circulatory system.

Some of the symptoms of the disease include foul and light-coloured stools, malnutrition, diarrhea, decreased appetite and weight loss, many vitamin deficiencies, growth stunting, stomach pain, skin rashes, and problems with tooth enamel.

This becomes very painful. Stomach ulcers are caused by a combination of factors, including the long term use of NSAID’s excessive acid in the stomach, and a bacterial infection. The most common symptom is a burning sensation or pain in the area between your chest and belly button. Normally, the pain will be more intense when your stomach is empty and it can last for a few minutes or several hours. Non surgical treatments include protein pump inhibitors, and antacids to neutralize the stomach acid.

The frog and the human system are both a set of hollow tubes, per se, that help digest food and help the body gain the nutrients that it needs in order to function. The organs are the same, such as the esophagus being a tube, or a “trough”, a large intestine being the waste collector and forming feces to be excreted from the body. But, humans only have one set of teeth, while frogs have more than one set. Frogs also do not have an appendix.]]> 2017-06-05 20:22:40 UTC https://padlet.com/stenstrb/6s64xy6s5xho/wish/175276570 Pictures stenstrb https://padlet.com/stenstrb/6s64xy6s5xho/wish/175915748 http://kidshealth.org/EN/images/illustrations/K-digestive-275x267-enIL.gif
