1. Why Is Cell Differentiation Important In The Formation Of Organ System
1. Why is cell differentiation important in the formation of organ systems?
- When a cell differentiates, it becomes more specialized and it may undertake major changes in its size, shape, metabolic activity, and overall function. Cellular differentiation is important and occurs so cells can specialize for distinct functions, such as an organ system, within an organism. All cells in the body, beginning with a zygote, contain the same DNA then go through cell growth and division, also called mitosis, then become specialized cell types. These specialized cell types are epithelial cell, connective tissue cell, nerve cell and muscle cell which all come together to form tissues. These tissues then come together as a functional unit.

What are the components of the Extracellular fluid (ECF) and where are they are found?
- Extracellular fluid serves as the transition between an organisms’ external environment. Extracellular fluid is found outside the cells and has two components. One component of ECF is blood plasma, which is the extracellular fluid inside the blood vessels and second, interstitial fluid which surrounds most of the cells.
4. Why are neurons considered to be excitable cells?
- Neurons are cells that conduct electrical impulses and are considered to be excitable cells due to the fact that they can change voltage across the plasma membrane.
5. List the 3 mechanisms that allow us to regulate homeostasis and provide a brief description of how they work.
- Three mechanisms that allow us to regulate homeostasis are the receptor, the control center and the effector. The receptor receives changes that are happening in the environment then it goes to the control center where it processes the information and finally the effector responds to the commands of the control center and makes changes that are needed. This is process that is always in function to maintain and restore homeostasis.
