1. Metabolism
Metabolism is defined as all the chemical processes that occur in the body. This involves a process of breaking down chemical substances, which is Catabolism, and a building up of chemical substances, which is Anabolism. Examples of metabolism include digestion, as it involves a process of breaking down; it also includes the synthesis of proteins in cells as well as glycogen synthesis from glucose, which are both anabolic processes.
2. Responsiveness
The body's capability to detect and react to changes and stimuli is referred to as responsiveness. Examples include drawing your hand back from a hot object as well as the body's responsiveness to other internal stimuli such as drops in blood sugar and temperature.
3. Movement
Movement is defined as all movement of the body, from the biggest motions of our limbs to the smallest motion of cells and structures inside the body. Examples of this include movement when we run and the cilia that line our bronchi that move microbes and debris out of the airway.
4. Growth
When the body's size increases from an increase in existing cells' size, this is defined as growth. An example is the growth of muscles from exercise due to the addition of myosin filaments to muscle fibers.
5. Differentiation
Differentiation is the cell's development to become a specialized cell. An example is our stem cells which are versatile as they can specialize into muscle cells, blood cells, etc.
6. Reproduction
Reproduction is defined as the creation of new cells for growth, repair, or the production of an individual. The simplest example of this is cellular division, mitosis, and meiosis.
