around the world are constantly trying to get young people to start
volunteering and do good deeds for their local communities.  Persuading young people to take action on
local issues is great. Spending your free time being able to help out is a
wonderful feeling inside and out.  As I
am still a high school student involved in multiple clubs you come across these
experiences quite easily. Being involved in Key Club and National Honors
Society have given me the opportunity to have experience on multiple occasions.
Penn Hills High School tends to have a blood drive once a month.  In my personal opinion, I believe that blood
drives have had the biggest impact on me.  

most common question asked is why should I do this? Or how am I going to
benefit from this? Do not be selfish, maybe think about other people’s lives
before yours for once. Donating blood helps millions of lives. Did you know
that just one pint of blood can save up to three people’s lives ( Me
knowing that I can save someone’s life by giving just one pint of my blood
gives me an indescribable feeling. Maybe for someone else cleaning up a yard
and making the community look more presentable gives you that feeling, but as I
a nursing student giving blood is just right.

is essential for life ( Blood carries oxygen and nutrients throughout
the body, fights infections, and heals wounds ( One plus to donating
blood is that you can figure out what blood type you are. Knowing your blood
type is important when in case of an emergency. Accidents can happen at any
time and any place. If for any reason you, a family member, or even a friend of
yours needed blood you could possibly be able to save their life. How would you
feel if someone close to you was dying and the only thing they needed to stay
alive was some more blood? You could have just saved that life if the blood
types were a match. The process of giving blood takes ten minutes or less but the
before process is much longer ( Anyone that is 16 years of age, weighs
at least 110 pounds is able to donate blood ( You are able to donate
blood every 56 days ( That little pinch cannot be as bad as what they
are going through. Every three seconds someone needs blood, and one out of
every three people that are admitted to the hospital need it as well (
One out of every three people will need blood in their lifetime ( Also,
babies that are born prematurely often need blood to survive ( You may
think that the need for blood is not needed that much, but it is. Severe burn
patients need at least 20 units of platelets during treatments. ( Blood
and platelets of all types are needed for premature infants, child cancer
patients, and also children having open heart surgery ( People that
are anemic also need blood for transfusions to increase their iron levels
( The need for blood is constant (

In the year 129 AD, Galen was born (Galen). He
is sometimes identified as Galen of Pergamon or Claudius Galen (Galen). Claudius
Galen was the greatest physician of Ancient Rome (Albu). Hippocrates laid the foundation of Greek Medicine
as Galen further developed in theory, practice, and carried Greco-Roman
medicine to its peak (Albu). The city of Pergamon was wealthy in the
Eastern Roman Empire (Galen). Pergamon, which today is Turkey, was Galen’s
ideal place to grow up in a highly active community (Galen). As Galen was
growing older he was forced in his father’s footsteps. As his dad had a dream
in Greek God of medicine, Galen must put his effort into healing and medicine
(Galen). In favor of medicine, he dropped out of his dream of studying philosophy
(Galen).  Galen began to think that this
all came about because of Asclepius and that he was in need of much help

12 years, Galen became a physician (Galen). First, he became a trainee doctor
at a local hospital, where he learned four years of methods from Satyrus
(Galen). As this was occurring he was left with an abundant amount of money
from his father Nicon (Galen). Traveling around the Mediterranean at just 20
years old learning techniques of healing and medicine (Galen).  Alexandria’s medical school, where Galen
studied for five years was where he ended his traveling and returning to
Pergamon at the age of 29 (Galen). Galen was a discoverer (Galen).  His methods became known as Galenism (Galen).
As discoveries done with both success and failures, Galen had an experience
with just both types. He succeeds in many which include, patient pulse, urine,
nerves, and more importantly with my topic blood. He is known for his discovery of blood in
human arteries and for his dissection of the human cranial nerves, the nerves
that supply key areas of the head, face, and upper chest (Medicine Net). Galen
had the first systematic description of the movement of blood (Edwards). According
to the Galenic system, blood was created in the liver from ingested food and
flows to the right side of the heart (Edwards). Blood flows through various
places throughout your body. For the next 1500 years Galen’s substandard understanding of physiology
was built for the practice of medicine (Edwards). Of course, challenges were
faced, but they were overcome. In the 1200’s, Ibn-al-Nafiz, an Arab
physician, required no visible passage from the right side of the heart to the
left side of the heart (Edwards). After his study, he traced the pulmonary
circulation (Edwards). In the seventeenth century, William Harvey brought a precise
idea of the circulatory system to the world (Edwards). The volume of blood that
is pumped with each heartbeat but realized that the liver would have to create
several times the body weight in blood every day if the blood was actually
being consumed is the Galenic Theory (Edwards).  So, your liver has to create more body weight
for the blood to pump with your heart. This is when they used animals for
experiments instead of people to see if it would work. They found that an
animal could be completely exsanguinated (the process of blood loss) in a
matter of minutes by cutting an artery in Harvey’s experiments (Edwards).

quantity for blood was restricted (Edwards). This was established through
testing, using cold-blooded animals, as their circulation could be slowed
down (Edwards).  If they would have used
humans for the test trials a lot of people would have died. Today, we use
people for trials when it has been shown to already work on an animal. Back
then, technology use and medical use were not as intense as it is today, that
was just the start of it all.

blood plays an important role in today’s society. As you can see that in order
for certain procedures to go smoothly you will need extra blood as a
precaution. People tend to not donate anymore because they don’t see a reason
for it, I just gave you the reasons, saving lives. We see younger people
passing away from unexpected accidents, but if there was a way to stop it you
could. This, for instance, is a way to save a life, giving blood just once to
possibly save three people’s lives. After the semester is completed I will
continue to donate to save lives each and every day.
