Organs and Organ Systems to OrganellesThe human body consists of some(prenominal) different organs and organ systems, which ar do up of billions of cells. Inside these cells there are tiny 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 spill 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 aver 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 wizard primary area. The brain sends messages by neurons and electric impul ses, while the nucleus does it by means of messenger RNA. The body has a shape that is contributed to by the muscular and atrophied 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 arent united by anything like a ligament or a tendon and cytoplasm doesnt 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 packaging order. All three of thes organelles play an important role in processing molecules in the cell.
