Each cell in your body was made from an already existing cell.
What are human body cells made up of. Understanding this hidden half of ourselves - our microbiome - is rapidly transforming. Oxygen carbon hydrogen and nitrogen. Scientifically a Cell is the basic unit of life.
It all comes to who you ask. Epithelial tissue is made up of epithelial cells which are vastly different from the muscle cells we just talked about. Likewise how many eukaryotic cells are in the human body.
Bones are made up of a matrix of collagen and calcium phosphate minerals. Haemoglobin is a molecule in red blood cells that binds to oxygen allowing it to be transported through the blood. Within the centre of the cell is DNA and RNA both extremely complicated molecules.
Before you start thinking we should float away with all the oxygen hydrogen and nitrogen atoms remember that the oxygen molecules are mainly part of the water in our body H2O. Protons and neutrons are made of quarks. In fact over half of the human body is made up of water 50-70.
They are joined tightly. A biologist would say youre made up of around 100 trillion cells. Many species of bacteria and other microorganisms live inside and outside of your body.
Molecules are collections of atoms. They also contain most of you bodys water. It revealed that of the 100 trillion cells that make up a human body around one in ten are actually microorganisms such as bacteria and viruses.
