The body has many systems. Each system has its own job and together they make the body function. Each system is important to our body and how our body functions.

 

Nutrients that are absorbed form the digestive system travel to other parts of the body through the circulatory system. The blood that travels through the body carries things like oxygen, nutrients, and wastes such as carbon dioxide. All blood travels in one direction and cannot turn around. In activity 18 the model showed were the nutrients is sent and were it comes from. For example, oxygen and nutrients are sent to the liver, kidneys, brain, lungs, heart and many other places.

 

The main organs in the respiratory system are the lungs. The lungs take in oxygen by inhaling, and get rid of carbon dioxide by exhaling. The body takes the oxygen and delivers it to vital organs. It then gets rid of the waste. In activity 17 people exhaled carbon dioxide into a bag with B.T.B. solution. Then tested how much carbon dioxide was in their breath. They did this by dropping solution into the bag trying to restore the original color. The conclusion was that it took from 2 to 10 drops to restore original color.

 

The digestive system is an important system.  It breaks down food by using a mechanical and chemical break down. The process starts in the mouth where your teeth and saliva starts the mechanical break down. The digestive system has a long tube and food is absorbed along this tube. The digestive system breaks down food so that it can be absorbed. After food is completely broken down it is called nutrients. In the process of absorption nutrients leave your digestive system and go into your blood. In the chemical break down lab I learned that broken pieces got broken down faster than the bigger pieces for example it took 2.38 for the biggest piece and 2.08 for the second biggest piece.

The skeletal system provides a frame to support and protect body parts. The skeletal system protects the heart and lungs with the ribs and the vertebrae protect the spinal cord. The adult body is made up of approximately 206 bones, which are made of several different types of tissue. For example, there are blood vessels, marrow cavity, cartilage, compact bone, and spongy bone. There are also many different types of bones such as the skull, fibula, tibia, clavicle, ribs, and humerus.

 

The function of the nervous system is to send and receive electrical messages. It also keeps all your organs working properly it allows you to speak, smell, taste, hear, see, move, think and gives you emotions. It acts as a central command post. There are two types of nervous systems the central nervous system, peripheral nervous system. The central nervous system controls your brain and spinal cord. The peripheral nervous system consists of communication pathways that connect all the areas of your body to your central nervous system. A neuron consist of a cell body from the cell body information is transmitted through the axon.

 

The lymphatic system cleans out the body and fights pathlagens. The fluids go through vessels called limps. Particles to large go to the blood vessels. The limp goes through vessels by squeezing the skeletal muscles. Limp nodes remove pathlagen or dead cells out of the limp system. The times reales the lympothetys

 

Each system is important to our body and how our body functions. Each system play an important roll like the skeletal system for example, is what holds your body together. Therefore, with out these systems the body cannot function.
