The human body consists of many different organs and organ systems, which are made up of billions of cells. Inside these cells there are ?ˆ?tiny organs?ˆ?,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.Order now
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?ˆ™t joined by anything like a ligament or a tendon and cytoplasm doesn?ˆ™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 ?ˆ?packaging site?ˆ?. 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 doesn?ˆ™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?ˆ™ll know why they call them ?ˆ?tiny organs?ˆ?. Anatomy and Physiology
