Document Summary
Two key topics covered in this lecture firstly, discussed about the hierarchical structure of the human body. Firstly can think of the varying types of cells that form tissues and two or more different tissue types form organs and a collection of organ systems from humans. The four different types of cells are: nerve, muscle, connective, epithelial cells. They form respectively, nervous tissue, muscle tissue, connective tissue, and epithelial tissue. Important to note that blood is considered part of the connective tissue. Another way to understand the organization of the human body is through fluid compartmentalization. You have have the blood plasma, interstitial fluid (located in the interstitium) and the intracellular fluid. The water content of these fluids in decreasing order is the intracellular, interstitial fluid and plasma. The second key topic covered in this lecture is homeostasis. It is the maintenance of a steady state. The maintenance of life requires a narrow range of dynamic equilibrium to be maintained.
