The course Cell biology partim physiology focuses on the function of the human cell. First, we go back in the evolution to shed light on the origin of life and of uni- and multicellular species. In particular, the functional organization of the cell and of different cells together is important for understanding the functioning of the cell. In the second part, current scientific and medical knowledge of the physiology of cells and tissues is extensively discussed. How the cell can function and interact with the environment is key, in order to clearly define and understand the cell as a functional unit of the human organism. In addition to general cell physiology (cells, tissues, membranes, transport, signal transduction), an introduction is also given on neurophysiology, physiology of blood and respiration and muscle physiology. The CS pathophysiology focuses on the physiology of the malignant cancer cell.
