Organs and Organ Systems to Organelles
The human body consists of many different organs and organ systems, which
are made up of billions of cells. Inside these cells there are â€œtiny
organsâ€,or organelles. These organelles act in many ways like the organs and
systems of the body. To better understand the relationship between them, I
am going to compare and contrast their differences and their similarities.
The brain is the control center of the human body. It sends and receives
messages to the rest of the body. The brain is made up of many different
parts, and each part has its own job. The nucleus of a cell is very similar
to the brain because it is the control center of the cell. It too sends and
receives messages, only throughout the cell. The nucleus is made up of many
other parts, which have
all have special jobs also. The brain and nucleus are alike in several ways,
but contrast in one primary area. The brain sends messages by neurons and
electric impulses, while the nucleus does it by means of messenger RNA.
The body has a shape that is contributed to by the muscular and skeletal
systems. Bones provide the body with framework, and the muscles allow
movement. The cell has similar organelles, the cytoplasm and the
microtubules, which provide the cell with form. The microtubules are
tube-like structures that act like bones do in humans, they give shape and
support to the cell. The cytoplasm is a jelly-like substance that keeps
things in place, and restricts the
movement of organelles in the cell. The main difference between them is the
fact that microtubules arenâ€™t joined by anything like a ligament or a tendon
and cytoplasm doesnâ€™t contract like muscles do.
The digestive system of the human body is made up
