2. Function of the Respiratory
System
The function of the respiratory system is a
series of organs responsible for breathing
in oxygen and expelling carbon dioxide.
The most important organ of the
respiratory system are the lungs. The
reason why is because they carry out
the exchange of gases as we breathe. In
addition as this process is working our
body is provided with blood which lets
the whole cycle function.
3. Components of the Respiratory
System
Ribcage
Intercostal
muscles
Deoxygenated
Blood
4. Adaptions
1. Ventilation – the rib cage adapts when you inhale or exhale, as it
follows your breathing.
2. Alveoli - The number of alveoli in the lungs increase to get more
gas exchange to occur.
3. Diaphragm– The strength and endurance of the diaphragm
improves as you train them to adapt to what you want them to
do.
4. Capillaries – more capillaries are formed in the lungs over time, so
that more blood can flow in and out the lungs.
5. Gas exchange – the exchange of oxygen and carbon dioxide
improves as they become larger, this makes it more efficient for
the respiratory system to work efficiently.
6. Lungs – We have two hopefully healthy lungs which make it more
efficient for us to live.
7. Exchange – the walls of the alveoli are thin so the exchange
happens quick.
8. Trachea – The trachea adapts to how we are feeling, for example
if its infected it will be swollen or if its healthy it will be clean.
6. How does the Volume and Pressure change
the lead to the Ventilation of the Lungs?
What ventilation means is the process
of breathing I and out. The pressure
change when you inhale changes
because your ribs are going outwards
as the diaphragm moves further
down, which lets the ribcage to have
more space for its breathing process.
Later on when we exhale the opposite
happens the rib cage becomes
smaller as they are more relaxed and
there is less air in them.
8. Function
The function of the circulatory system is to
transport materials throughout the entire
body. For example it transports nutrients,
water, and oxygen to all the different types
of body cells. After it carries away the wastes
such as carbon dioxide that the body cells
produce. This process connects to all your
body cells which is a amazing process.
10. Adaptions
1. Heart rate – Your heart adapts to the amount of sport you do so if you
exercise a lot it can pump faster, without suffering.
2. Blood Cells – They travel faster if you exercise because your muscles are
built up and the process because normal.
3. Septum – the wall separates the right and left ventricle, it adapted
because it didn’t let oxygenated and deoxygenated blood to mix.
4. Valves – They open and close which allows one-way flow to happen
5. Arteries have a bigger amount of muscle than veins which makes them
thicker, that means that they can stand the pressure from the blood flow.
6. Right Ventricle – It is thin which lets it easily only pass by the lungs and not
around the whole body.
11. The Importance of one-way Flow
Our heart pumps oxygenated and deoxygenated blood
throughout the body. The blood flows through the capillary
beds and then get to all the cells in the body. Later, the
deoxygenated bloods takes part. As, the oxygen is
removed from the blood and it starts to flow to the lungs
where it can become healthy again and then it is sent
back through the veins, and then to the heart. This is like a
cycle, and it always has to happen the same so that
nothing clogs, as your heart needs blood and without the
one-way flow we would be dead.
