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 a€œtiny 
organsa€?,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 arena€™t joined by anything like a ligament or a
tendon 
and cytoplasm doesna€™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 a€œpackaging sitea€?. 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 
arranged. 
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 doesna€™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, youa€™ll know why they call them a€œtiny
organsa€?.
