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:

Portland, Oregon - Reservoirs

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).

The Circulatory (Cardiovascular) System

Image
The Structure & Function: What is the function of the circulatory system?   The job of the circulatory   system works on circulating blood, lymph, nutrients, oxygen, other gasses, and hormones throughout the body, hence the name circulatory system. The circulatory system also balances temperature and pH balance while protecting the body from diseases. The circulatory system consists of the heart, blood vessels, blood, lymph, and the lymphatic glands & vessels. https://s3.amazonaws.com/classconnection/128/flashcards/8043128/png/insideheart1328771781022-14DEA48509547B9E19F.png What are the names and functions of the major organs in the circulatory system?  The names & functions of the major organs in the circulatory system are... Heart (cardiovascular): The heart is an organ that pumps blood through the body, providing oxygen & nutrients to the tissues (such as muscles). The heart also works on removing carbon dioxide and other unwanted wastes (whi

The Renal (Excretory, Urinary) System

Image
The Structure & Function:  What is the function of the renal system? The function of the renal system is the eradication of wastes manufactured by homeostasis (this word comes from two combined words in Greek: "homeo" meaning similar, & "stasis" meaning stable). The organs that are used in this process are the lungs, the liver, & the kidneys. What are names & functions of the major organs in the renal system? The names & functions of the major organs in the renal system are... Kidneys: the kidneys are organs that receive the waste from the body. The kidneys then percolate things from the waste, such as salt, urea, & excess water which is disposed from the body as urine. Skin: The skin executes its function through sweat glands. Sweat is used to cool us off as well as to get rid of unwanted oils, salt, water, and other gratuitous elements that ooze from small pores in the skin. Lungs: The lungs, an important organ in both th

10/24 Interdependence of Organisms

Image
              Interdependence of Organisms The interdependence of organisms is when organisms depend on each other for food to survive. Their whole reason to survival is so that they can live long enough to reproduce.  Backward Looking - Reflection: If an animal disappears from the rainforest then the animal who depends on this dying species for it's survival will also die due to lack of food. And so on and so on. Also it will affect the animal/plant that it does eat, meaning if the humming bird disappears from the rainforest or other biomes it will affect flowers or other plants, meaning they will over populate or under populate and that biome/rainforest will not have a healthy balances of plants and animals. Inward Looking - Reflection: I liked the work that I did this week because I could understand all the animals and the food chains/webs. I also liked it because of the fun activities that we did.I liked it because instead of using everyday textbooks, we get to google thi
