Organs And Organ Systems To Organelles


Organs And Organ Systems To Organelles Essay, Research Paper

The human body consists of many different organs and organ systems, which

are made up of billions of cells. Inside these cells there are ?€œtiny

organs?€?,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 aren?€™t joined by anything like a ligament or a tendon

and cytoplasm doesn?€™t contract like muscles do.

The digestive system of the human body is made up of several organs that

work together to break down food so it can be used in the body. Similar

organelles in the cell are endoplasmic reticulum, ribosomes, and the golgi

body. Endoplasmic reticulum is used in the synthesis of molecules entering

the cell. The ribosomes produce protein and send them to the places in the

cell that needs it.

The golgi body is the ?€œpackaging site?€?. All three of thes organelles play

an important role in processing molecules in the cell. However, they are

different from the digestive system in their anatomy and the way they are


In the human body, the largest organ, the skin, is responsible for

protecting the body. It is the outer covering and it allows things in and

out of the body through pores. In the cell, the largest organelle is the

cell membrane and it too is responsible for protecting the cell. Both the

skin and the cell membrane

have more than one layer. The primary difference in the two is the cell

membrane is selectively permeable.

In order for human life to continue itself, it must reproduce. The same

applies to cells. The reproduction system in the human body is responsible

for this. The organelle in the cell which is compared to reproduction are the

centrioles. They aid in the distribution of parts in the nucleus to newly

formed cells. Although the two share the job of reproduction, they are

different in many ways. The uniting of sperm and egg is the main difference.

This doesn?€™t occur in cell reproduction.

In cells, organs, and organ systems the anatomy may be very different in

some ways, but the physiology in some cases is very similar. When you think

of an organelle now, you?€™ll know why they call them ?€œtiny organs?€?.
