The digestive system helps the body break down food, so nutrients can be used for cell repair, growth and energy. The digestive system is also responsible for storing and excreting solid wastes.
The cardiovascular system interacts with the digestive system by carrying digested nutrients throughout the body via the bloodstream, explains Southwest Tennessee Community College. The digestive system also works with the excretory system to control the amount of water in the body and release undig
For a science project focusing on the digestive system, kids can make a model stomach and a model small intestine. They can also make a wide array of digestive components, but the stomach and small intestine are the easiest and most enjoyable for children.
The digestive system is that it works even when a person is upside down, the small intestine is about 22 feet long, and some animals don't have stomachs. The platypus's food, for example goes straight to its intestine without passing through a stomach.
The amount of time that digestion takes varies from person to person, but on average it takes around 33 to 50 hours. It takes 6 to 8 hours for food to pass through the stomach.
Digestive system diseases include gastroesophageal reflux disease, or GERD, celiac disease, Crohn’s disease and diverticulitis, states Everyday Health. It is common to have a digestive system problem, and patients with symptoms of these conditions should talk to their doctors.
According to Branch Basics, digestion begins in the mouth when the process of chewing starts. Salivary glands will secrete a mucus, which assists in lubricating the food before swallowing.
Fish have a digestive system that begins at the mouth and ends at the anus. It is usually comprised of a mouth, esophagus, stomach, pancreas and intestine. Not all species of fish, however, have a stomach, such as Cyprinidonts and Cyprinids, and herbivorous fish have longer digestive tracts than car
Food begins its journey through the digestive system in the mouth, before being pushed by a series of involuntary muscle contractions through the esophagus, then the stomach, and then the small and large intestines. The digestive system is essentially a series of long, hollow organs lined with muscl
Digestion is the process that breaks food down into the molecules that the body needs for all of its metabolic processes. Food is the body's fuel source and the source that the body's molecules and cells use to build and repair the body, but the body cannot use the food unless it has been digested.
