1. Essay about the human brain
In this paper one will learn the different parts of the brain and their functions. Although the brain isn't
the largest organ of the human body it is the most complex and controlling organ. It is amazing how
complicated the brain is. The brain controls every action within and out of your body. The brain has
main areas that contain different areas that have specific functions. For instance the basal ganglia
holds the lentiform and the caudate.
The brain isn't just "THE BRAIN" it is actually a group of many parts. They help to inform the brain
on the things going on with the human body. The brain is split in to two main parts, the left and the
right hemisphere. The left hemisphere has about the same areas as the right hemisphere. The only

The corpus callosum is a bundle of nerves that connects the two hemispheres. The area that passes
and processes information concerning touch, pain, temperature, and pressure on skin is the
thalamus. The limbic system controls your behavior and emotions. It is involved in emotions such
as fear, rage, pleasure, and sorrow. In the prefrontal area of the frontal lobe emotional traits are
controlled. In the temporal lobe expressed behavior is controlled. The parietal lobe discriminates
sensory. The occipital lobe is where visual interpretation takes place. Pons is a crossroad for nerves
going up to the cortex, to the cerebellum and then down the spinal cord. The cortex is the outer gray
area where thinking takes place. The olfactory cortex receives senses from the nose that it then sorts
out. The area that identifies what we see by working out movements, colors, and shapes is the visual
cortex. The area that receives taste senses is called gustatory cortex. The area responsible for
analyzing data, performing memory functions, learning new information, forming thoughts, and
making decisions is the cerebral cortex. The motor cortex is involved in muscle movement. The
cerebellum is vital when carrying out complicated, skilled movements. It is much like a mini brain.
If before you read this paper you thought the brain was a "one man machine" I'm sure your opinion
has changed after reading his paper. It is amazing how god has created the brain to have so many
areas

2. Essay about Suicide
Someone, somewhere, commits suicide every 18 minutes. You might never be able to tell who it
will be, it could be the person sitting right next . Statistics reveal that approximately three million
youths, between 12–18, have either thought about or attempted suicide in the past year. More than 1
/3, actually succeeded.
Only in the past two decades, have depression and suicide been taken seriously. Depression is an
illness that involves the body, mood and thoughts. Depression affects the way a person eats and
sleeps, feels about themselves, and the way they think of the things around them. It comes as no
surprise to discover that adolescent depression is strongly linked to teen suicide. Adolescent suicide
is now responsible for more deaths...show more content...
Adolescence is a stressful experience for all teens. It is a time of physical and social changes
producing rapid mood swings from sadness to elation. Even an emotionally healthy teenager may
have the constant fear of not being good enough, not making the varsity team, or getting good
grades. Special situations such as a parents divorce can trigger intense sadness and feelings of
wanting to die.
People who usually experience depression, can seem fine. But there are many key signs to show that
they are depressed. Such as, change in school performance, eating habits change, constant
unhappiness, low self esteem, guilt, social isolation, inability to concentrate, irritable or angered
easily, or has a severe lost of energy.
For a teen suffering from severe depression, has feelings of worthlessness that dominates their day.
Despair is ever present and emotional pain feels like it will never end. Any situation of anger or
disappointment may cause the teen to cross the line from wanting to die, to actually trying to kill
themselves.
Many of them feel pains inside of them, that they can't describe when someone asks them how they
feel. They just know that they are sad, or angry, or upset. Many teenagers will try to communicate
their pains through

4. The Heart Essay examples
"The heart" The Heart is a very important organ in the body. It is what keeps your blood flowing
and your organs going. It is a tireless muscle that pumps more than two thousand gallons of blood
every day. The blood that is pumped is filled with nutrition and oxygen (Colombo 7). It travels
through out your body in less than sixty seconds. So it needs to be taken extra good care of. When
abuse is put on the body, the heart's performance is not at its best. The Heart is a major organ that
needs loving and care. Everyone has only one and by abusing it, they are cutting their live span
little by little. People can live their lives freely but how they choose to live them could be the
difference between life and death.

This is why patients who are in comas or vegetable states live because although they may have no
nerve function, their heart beats on. The heart is what keeps all living breathing species alive,
animals or humans. If the heart was to shut down but the nervous system continued and was active,
it would not matter. The entire body would shut down because once the supplier no longer delivers
what is needed; organs will no longer function correctly, therefore causing irreversible damage.
Arteries are what carried the rich oxygenated blood from the heart to the rest of the organs
throughout the body. The Veins are what bring back the carbon dioxide blood to the heart. It then
has to be put through a cycle so that it can be shipped back out. Blood travels from the right atrium
through the tricuspid valve, to the right ventricle. From there, it is pumped to the lungs, the
oxygen–rich blood goes to the left atrium and then through the mitral valve to the left ventricle
where it goes to the aorta to be pumped around the body (Colombo 7). What looks to be a
complicated process that would take hours or minutes is actually done in a matter a seconds. As the
population ages heart failure is expected to increase exceptionally. About twenty–two percent of men
and forty–four percent of women will develop heart failure within six years of having a heart attack.
"Thirty years ago patients would have died from their heart attacks!" (Couzens)

5. Essay about social anxiety
Social Anxiety
Social anxiety is the fear of social situations and the interaction with other people that can
automatically bring on feelings of self–consciousness, judgement, evaluation, and inferiority. Put
differently social anxiety is the fear and anxiety of being judged and evaluated negatively by other
people, leading to feelings of inadequacy, embarrassment, humiliation, and depression. If a person
usually becomes anxious in social situations, but seems fine when they are by them selves, then
social anxiety may be the problem.
Social anxiety disorder or social phobia is a much more common problem then psychologists
originally thought. Millions of people al over the world...show more content...
It can affect even people who are experienced at speaking in public and do it regularly. At its worst,
it can make it impossible for the sufferer to speak in public at all, even to ask a question.
People who suffer from a social phobia will worry a lot about making a fool of themselves in
front of other people, and will feel very anxious before going into any of the social situations that
worry them. They may go through, in great detail, all the embarrassing things that could happen.
When they are actually with people, they will feel even more anxious, and may be unable to say, or
do, what is intended. In a way, it is a self–fulfilling prophecy. You worry so much about looking
worried that you actually do look worried. People experiencing both of these types of social
phobia have many of the same physical symptoms. You may get a very dry mouth, sweat a lot,
and feel your heart racing. Other people may be able to see some of the signs of this anxiety, such
as blushing, stammering, shaking and trembling. Sometimes you may breathe too fast, which can
give you feelings of numbness or pins and needles in the fingers and toes. This can make the
anxiety even worse. These feelings of fear and bodily symptoms can end in a panic attack. This is a
short period, usually lasting only a few minutes, during which people feel overwhelmingly anxious,
terrified of losing control, and may feel

6. Homeostasis Essay
Homeostasis
Homeostasis works to maintain the organism's internal environment, where the body's processes are
able to function at a level that would allow life to continue in that organism. The three systems which
are controlled by homeostasis are the respiratory, cardiovascular, and muscular systems.
Changes to the cardiovascular system are often a result of changes in the activities of other systems.
The heart rate, the cardiac output and the blood pressure change to different degrees of bodily
activity. The heart rate slows and cardiac output falls when demands on bodily systems are less
high. However the opposite is true when demands on the bodily systems are high, the heart rate

All systems must have homeostasis to maintain stability and to survive. Homeostasis is so important
because it can allow an animal to adapt to a changing environment. The body attempts to maintain a
constant level of physical output to achieve homeostasis. However, it can only work within its limits,
where extreme conditions can disable the negative feedback mechanism.
In humans, the process is a little different. It involves a constant monitoring of lots of different
factors. An example of one of the factors it monitors is the gases oxygen and carbon dioxide. The
concentrations of these substances in body fluid remain unchanged, despite changes in the external
environment.
The body can regulate its internal environment through feedback systems. A feedback system is a
cycle of events in which the condition of the body is monitored, changed, re–monitored and
re–evaluated. Each monitored variable such as temperature, blood glucose and blood pressure is
termed as a controlled condition. Any disruption that changes a controlled condition is called a
stimulus. Only three components make up the feed back system – a receptor, a control center and an
effecter.
Receptor – is a body structure that monitors changes in a controlled condition and sends input in the
form of nerve impulses to the control center

Since anyone at any age can be stressed there is no certain population that is effected the most. I
would say that teenagers get stressed easily due to school, spots and or jobs. The thing that
stresses most high school student out is picking and choosing what they are going to do after
high school and what college they will be going to if any. People a little bit older after college could
be stressed by trying to find a job or trying to find or support a family. Older people could be stressed
if they are running out of money but besides that older people are probably the least stressful people
in are population.
Stress is not only affected in the work place and at home, it is also affected during sports. There is a
