The Digestive System

The Structure & Function: 

What is the function of the digestive system? The function of the digestive system is to break down the food, extract the nutrients, and send those nutrients to the rest of the body so the body has the energy to function properly. The digestive system then sends the waste (the invalid food) to the colon where the body can dispose of it properly. The organs involved in digestion include the mouth, throat, esophagus, stomach, small intestine, large intestine, pancreas, liver, & gallbladder.

What are the names & functions of the major organs in the digestive system? The names & functions of the major organs in the digestive system are...
  • Esophagus: The esophagus works on carrying food, saliva, & other liquids from the mouth to the stomach for digestion.
  • Stomach: When the food arrives in the stomach, the stomach begins digestion and then regulates the amount of food and liquids sent to the intestines for the extraction of nutrients.
  • Small Intestine & Large Intestine: The function of the intestines is to extract nutrients and water from what we eat & drink. The small intestine is lined with tissue that is divided into three sections: the duodenum, the jejunum, and the ileum. The large intestine (or also known as the large bowel or colon) absorbs water from the leftovers (waste), creating what we call "poop".
What is the structure & function of the intestines?: The structure of the intestines is to fit within the body. The certain areas of the intestine (the small intestine to be exact) extract certain things, for example, the jejunum is about 2.5 m. long, and extracts sugars, amino acids, & fatty acids which are then put into the bloodstream. 
The large intestine is about five feet, three inches long. The function of the large intestine is to extract water from the waste. Then the dehydrated waste is sent to the anus where we dispose of it.

Interactions With Other Systems: 

Interactions with other systems: The interactions with the other systems that the digestive system has are the Muscular System, the Excretory (urinary) System, & the Circulatory System:

  • The Muscular System: As I mentioned before, a visceral muscle was found in the organs of what are part of another body system - the digestive system. The visceral muscle helped move food throughout the intestines, which is why the digestive system and the muscular system have another close relationship.
  • The Excretory System: The excretory system (or also known as the urinary system, which contains the kidneys) collects certain compounds from the blood and collects to create what we call "urine".
  • The Circulatory System: The circulatory system works with the digestive system to send the extracted nutrients sent around your body. The circulatory system also sends chemical signals to the endocrine system so the endocrine system can regulate the speed of digestion.

The Digestive System Analogy:

Explain the Digestive System Analogy: This analogy is comparing the digestive system to a reservoir. The esophagus would represent the sewer pipe. The stomach would represent the actual reservoir. The intestines would represent the filters, sending the nutrients (potable water) to the cells (the people) & the waste (the undrinkable water) to the colon for the body to get rid of.

REDESIGN: How Can I Make This System Better? 

How can you make this system better? 
I would make this system better by combining the excretory system & the digestive system together, considering they go hand-in-hand with each other (See: Interactions With Other Systems).
