“This is a compare and contrast research paper on 4 different types of
human body cells, which the one that are in this piece happen to be Osteroblast
(Bone Cell), Erythrocyte (Red blood cells), Mytocyte (Muscle Cells), and Neuron
(Nerve Cell). There will be information about all the cells, and a compare and
contrast of all 4 cells.”
Cells are what make up all living things;
they hold everything together, somewhat like building blocks. The human body can
hold trillions of cells; all different types all different sizes, shapes, and
colors. They do everything from providing structure, change nutrients into
energy, and even carry out specialized functions. Another thing is that cells
also are what make up our hereditary material and they even make copies of
their own cell structure (Genetics Home
Reference). Cells are what make up the structure of every living
thing in the world, however many people wouldn’t believe that cells are
important when cells are the most important thing in all living organisms in
the world.
Although
there are trillions of different types of cells here are a few. Bones are made up of cells called
Osteroblast, that’s what gives the cells the hardness and toughness. The
Osteroblast help the bones grow and repair themselves over time. Blood is what
helps the cells, get food and takes away the waste from the bones. If bones
weren’t made up of Osteroblast, broken bones would never heal on their own.
That’s why it’s so important that we have cells in our bones called Osteroblast (Discovery Communications Inc.). Another type
of cell, are Erythrocyte’s or better known as Red Blood Cells. The main function of
the Erythrocytes or Red Blood Cells is to move oxygen throughout the body. This
certain cell has no nucleus and has a lifespan of about 120 days. They
circulate the oxygen through tissues picking up carbon dioxide as they go,
which carbon dioxide is the main waste product that is formed in the cell. The
cells have a doughnut or circular shape to them and they are relatively small.
The contain pigment hemoglobin which is what gives the red color. They also
assist the cells when carrying oxygen and the carbon dioxide (Scott).
However those are just a few cells, here are
a few more types. Mytocyte cells are the main cell in the muscles;
the main function of the Mytocyte is to facilitate movement throughout the
entire human body. The way that these functions are achieved, are by adjusting,
or contracting the tissues that are in your muscles. For example skeletal
muscles allow you to move freely to certain consent. A great example is that
they allow you to turn your neck sideways but not 360 degrees (State Government of Victoria). The Mytocyte cell is the basic unit of all
the muscles in your body. The three main types of muscles are skeletal,
cardiac, and smooth muscle. Skeletal muscle cells form controllably, or
voluntary, for example like the muscles found in your legs. The smooth muscle
and cardiac muscles form uncontrollably, like the muscles that are in your
heart and stomach (Discovery Communications
Inc.). One more cell is the Neuron or the nerve cells; they are the main
cells that are in your nervous system. There are a few main functions of the
Neurons are to carry messages throughout our body, to receive, and to pass
electrical impulses. The neurons happen to be the smallest unit of the entire
nervous system, which sends signals to the rest of the body to do what the
brain, wants it to do, for an example our brain tells the heart to beat, your
diaphragm to breathe, or your eyes to blink (Poe).
Generally people wouldn’t think cells are
that important, but they really are, they do everything in our body and our
bodies are made out entirely of cells. Those 4 cells all had things in common
and things not in common. For example all of these cells have a different
purpose, the bone cell helps the bone keep its strong body and the red blood
cells help get bad waste out of our blood. Some things these cells have in
common is that they all support our bodies needs in some way, the nervous
system cells allow us to get senses and emotions to our brain to decode what is
happening, and the muscle cells allow us to gain muscle, and allows our heart
to beat on its own. They all don’t have a certain size or shape because they
all vary, besides the red blood cells. Their size is very small and they are
also doughnut or circular shaped (Scott).
However, in the end cells are the most
important thing in all living organisms. They hold us together, get the bad
stuff out of our bodies, and even make us have senses. Every single cell in our
body has their own job, to keep us and all living organisms living and keeping
us who we are as the world’s life forms.
