The Digestive System is one the 11 major organ systems in the human body that keep you alive.
The Digestive System
The Digestive System is needed to survive because it breaks down the foods and liquids you swallow into smaller pieces so it can be absorbed by your body and used for energy
Without it your body wouldn't have any energy Which pretty much means you would die
The Digestive System
The Digestive System's main parts are the esophagus,stomach,liver,gall bladder, pancreas,small intestines, and large intestines.
The Digestive System
Digestion is the mechanical and chemical breakdown of food into smaller components that are more easily absorbed
The process of digestion in the human body starts with the mouth
When you eat something edible like a hamburger for example
The Digestive System
After you chew the hamburger up and swallow the hamburger it takes a journey through your esophagus
After plummeting down your esophagus the hamburger will land in the stomach
Where it will slowly be broken down by the hydrochloric acids
The Digestive System
After being processed in the stomach the hamburger journeys to the small intestines
This is where the majority of the digestion and absorption occur
As it goes down the small intestines it meets small, finger-like structures called villi
Villi, along with their epithelial cells are covered with numerous microvilli to improve the absorption of nutrients
Then blood carrying the absorbed nutrients is travels from the small intestines and goes to the liver for filtering,removal of toxins, and nutrient processing
The Digestive System
After the small intestines is through with the remains of the hamburger it enters the large intestines
The food products that cannot go through the villi are mixed with other waste products from your body and become feces
The feces are stored in the rectum and later on removed from the body through the anus
