How the different body systems work together to accomplish tasks

Describe how various body systems work together to accomplish tasks such as eating, running, and sleeping. How does the healthy functioning of the body affect these tasks? What happens when the body is not at optimal health?

Transcript of How the different body systems work together to accomplish tasks

How the Different Body Systems Work Together to Accomplish Different Tasks Certain muscles in your body are attached to bones. This combination gives your body structure. But to do physical tasks such as running, different systems must work and move together. When you make the decision to run, you set in motion a long, but super fast chain of events When you make this decision, your brain sends a signal (along with all the information) through the spinal chord. The signal then travels along your nerves. Then it gets sent through your body to the muscles in your legs. In response to the signal, your muscles contract. This is what moves your bones and makes you run. This whole process is occurring as I type this. But the coolest part (other than the fact that your body parts work together to accomplish tasks in the first place) is that all this happens at a rate that exceeds the speed of light. Eating The process in which the message from your brain is sent to your muscles is also used in eating. Running The different systems that are involved include the nervous system, muscular system and the skeletal system. Other systems that are involved, but less directly are the respiratory system and the circulatory system. The respiratory system is always running and it brings oxygen into your body. The oxygen is then carried throughout the body in your blood by the circulatory system. When the oxygen reaches the different parts of your body, it is used, along with carbohydrates to create energy. When you put food in your mouth, your muscular system and digestive system immediately set to work. The saliva in your mouth starts to break down the food. Once the food is small enough to swallow, it travels down your esophagus. The muscles in your esophagus squeeze and force it down towards your stomach. It lands in your stomach, and the acid in your stomach breaks it down even further. When the food travels through the intestines, the nutrients are extracted and sent to the different parts of your body. The excretory system then disposes of the waste. When you put food in your mouth, you make the decision to chew, and your brain tells the muscles in your jaw to chew. Your body
has a number
of different things to combat being sick. Ever wonder
why you sneeze
and blow your nose so much when you are sick? This is one of
the ways your
body gets rid of
bacteria causing
the sickness. sweating and
fever are also
a way the body
deals with being
sick. when your body
heats you up into
a feverish state it
stimulates your immune
system. It also counters
the virus' multiplying. Your body sweating
is also a good thing.
Since your body is working so hard
your body tries to cool it off. This cools
your overworked self. This also disposes of
waste products produced
from the overexertion of
your body. The mucus cells trap the Bacteria and is thus excreted through
your nose When you`re sick it
also affects normal
things that you do
everyday. When you are sick you
are especially tired. This
is because you are using
a lot of energy to combat
the infection and that doesn't leave much for
normal things. This means that all the energy is being given out to the cells to fight the infection while your muscle cells and other cells do not have enough to perform normally. When you are
sick food also
doesn't taste as
good. Most of taste
is actually from smelling
it. The nose is blocked
up with mucus cells so
the scent cells cannot
land on the receptors
for scent in your nose. Sickness Organ systems
coincide to work more efficiently and couldn't function without one another. The systems work together
on a cellular level. This is called being interdependent. Interdependency The nervous system is very impotant and is interdependant with all the other sytems in your body. Without the nervous system,
all organ systems
couldn't function.
The nervous system
controls all systems
and tells them
when to do things. There are two
types of things
that it controls:
voluntary and
involuntary actions. A voluntary action
is something that
you decide to make your body
do such as running or eating. Voluntary actions are actions that you decide to do. When you run, you make that decision. Right now, I am deciding to type this. That is what makes it a voluntary. Involuntary actions are actions that you do, but don`t decide to do. Digesting food is involuntary because you don`t make the decision to digest and break down food, your body just does it. Breathing is also an involuntary action. It can be argued though, that since you can make yourself stop breathing, or that you can increase or decrease the rate in which you breathe, it is a voluntary action. But when you stop breathing, you will eventually pass out and you will begin to breathe again. When you are asleep, you also do not consciously decide to breathe, your body just breathes on its own. As you can see from our relatively lengthy presentation, the body systems are interdependant. They work together efficiently and accomplish different tasks, be it involuntary actions or voluntary actions. The nervous system is interdepent (to some extent) with all the other body systems. We hope you enjoyed our presentation and learned something that will assist you in the future.
