Document Summary
The human body is a collaboration between dozens of specialized organs. These organs are built from dozens of different types of cells. The type, location and numbers of these cells determine the structure and function of each individual organ. So before you can start learning about human anatomy and physiology, you need to learn the anatomy and physiology of the cell. First, a quick look at viruses and the two type of cells. Eukaryotic cell has a nucleus containing linear chromosomes (more complex than prokaryotic, one. Dna molecule per chromosome); has a plasma membrane, larger ribosomes, and several types of specialized, membrane-bounded organelles where some metabolic reactions take place; also some metabolism in cytoplasm. Virus: not a cell just genetic material (dna or rna) surrounded by a protein coat; may be wrapped in remnants of host cell membrane; no metabolism outside a host cell. Most cells can be seen with a light microscope this device uses beams of light.
