Transcript of CELL FUNTIONS COMPARED TO HUMAN ORGANS AND SYSTEM FUNCTIONS

One of the comparisons is the nucleus, every cell has one. The nucleus is like our human brain. The mitochondria are like our muscles. The ribosomes is like the production of proteins. So compared to our body is like the stomach which is where we get our protein There are many comparisons between our body and the cell body. Lysosomes contain enzymes which get rid of dead material it compares to our body by the kidneys they also get rid of waste but still absorb stuff that are needed by our body. The cell membrane protects the cells from the outside just like our skin does. The cytoplasm-plasma (liquid part of the blood that holds the red blood cells and white blood cells)compares to the cytoplasm which holds the organelles. Golgi apparatus does packing and export of proteins for use to other parts of the cell. Similarily arteries/veins which send(oxygenated and deoxygenated) blood from away and to the heart and to and from the cells. The vacoule is like our bladder. One of the major differences of the cell body and the human body is that its basically the same thing but the cell body scale is much smaller but with same functions. The brain sends messages by neurons and electric impulses, while the nucleus does it by means of messenger RNA some different things between the brain and the nucleus is that the brain it send messages through neurons and the nucleus sends the messages from 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 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. The ribosomes produce protein and send them to the places in the cell that needs it. 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. CELL FUNCTIONS COMPARED TO HUMAN ORGANS AND SYSTEM FUNCTIONS.
