Digestive System

Function:
The digestive system breaks the food you eat into nutrients and compounds. This is then absorbed into the bloodstream. Unwanted materials, waste, continue out of your body through the anus.
Organs:
Mouth-It is where digestion begins. When you start chewing your food it mixes with saliva and starts the process of breaking down food.
Esophagus-It transports food from the mouth to the stomach.
Stomach-It holds the food and continues the process of breaking down food. The food that is now a form of liquid or paste goes to the small intestine.
Small Intestine-It continues to break down the food. After absorbing all the nutrients the rest (waste) moves to the large intestine.
Large Intestine- The waste goes through the large intestine in liquid form which then changes into a solid. The solid waste is stored there until it gets passed on to the rectum.
Rectum- It receives solid waste and holds it. It's main job is to inform the person's brain that there is waste to be emptied out.
Anus- The last part of the digestive system is the anus. It controls solid waste from coming out when it's not supposed to.
Other Systems It Works With:
The digestive system works with the circulatory system. After the nutrients are broken down, they are sent into the bloodstream to be delivered all around your body. In addition the circulatory system sends chemical signals controlling the speed of the digestion cycle. If the digestive system didn't work with the circulatory system the nutrients absorbed wouldn't be sent out all over your body. As well as that, it works with the urinary system. The urinary system takes the waste that was once food, purifies it, allowing it to exit the body as urine and feces.

Activity:
We put crackers in a bag- into the mouth, crushed them- chewed, added water -saliva, then it went into the esophagus, after it went into the stomach, then added coke- acids, after it went into the small intestine which took some liquid and nutrients, while that was happening the rest went to the large intestine and they separated the rest of the liquids and solids, then the solids went into the rectum, and finally into the anus.

Analogy:

The esophagus, an organ part of the digestive system, reminds me of a water slide because it transports water and people from the top to the bottom. The esophagus carries the chewed food mixed with saliva from your mouth down to your stomach. The start of the slide is the mouth, the end is the stomach, and the person is the chewed food. These to things mirror each other even if what they are carrying is different.
Structure and Function (Small Intestine) :
The small intestine is a windy narrow tube that takes up most of the space in your abdomen. As the food passes through the small intestine the nutrients are absorbed and a main part of digestion takes place. The stretch of the small intestine is divided into three parts.
Duodenum: The duodenum may be the smallest of the three sections, but it is where most of the chemical digestion takes place. The digestive juices it contains breaks the food down into nutrients small enough for your body to absorb them.
Jejunum: Since the duodenum broke down the nutrients the can now be absorbed. The jejunum performs this function and sends the nutrients into the bloodstream to reach your cells.
Ileum: The ileum is an additional place of absorption in which bile salts and vitamin b12 are absorbed.

The small intestine is covered in villi which are little finger shapes that poke out from an intestinal wall. These allow the small intestine to absorb more nutrients because they increase absorption area. As well as that, the small intestine is very long giving it more time to break down and absorb nutrients. This helps extremely because the tube's diameter is around the size of your middle finger. As you can see the way the small intestine is shaped greatly effects how well it can carry out its function.

Fun Fact:
A little fun fact, when you hear a growling noise from your body, it is not your stomach, it is your small intestine that make that sound.
