Metabolism
- All chemical processes that take place within the body are collectively referred to as metabolism. Catabolism is a stage of metabolism in which complex compounds are disassembled into simpler constituents and energy is liberated.
Responsiveness
- Responding to changes in the internal or external settings is what responsiveness or irritability is all about. It involves noticing a stimulus and reacting to it.
Movement
- The body can move in many different ways. Molecules travel from one location to another within cells. From one area of the body to another, blood flows. Every breath causes the diaphragm to move. Contractility is the term used to describe a muscle fiber's capacity to contract and hence generate movement.
Reproduction
- Through the process of reproduction, life is passed down from one generation to the next. In a broader sense, reproduction also includes the synthesis of new cells for growth, repair, and replacement of aging cells. This is how cells reproduce. The survival of the human race depends on both.
Growth
- Growth is the process of expanding in size, whether it is through increasing the total number of cells or the size of each cell. Anabolic processes must go more quickly than catabolic processes for growth to take place.
Differentiation
- Unspecialized cells become specialized cells through the developmental process of differentiation, which gives them unique structural and functional properties. Cells differentiate into tissues and organs through this process.
