Physiological Structure and Life Process
The human body is a complex system made up of various physiological structures that work together to sustain life. These structures include organs, tissues, and systems like the circulatory, respiratory, digestive, nervous, and excretory systems. Each life process—such as nutrition, respiration, transportation, excretion, growth, reproduction, and response to stimuli—is carried out by specialized organs and systems. These life processes are essential for: Maintaining homeostasis (internal balance), Providing energy, Removing waste, Ensuring survival and reproduction. For example: The digestive system breaks down food for energy, The respiratory system exchanges oxygen and carbon dioxide, The circulatory system transports nutrients and oxygen, The nervous system helps in control and coordination. Together, these physiological structures and life processes form the foundation of biological function, allowing organisms to live, adapt, and interact with their environment.

⚗️ 1.3 – Investigate the Fundamental Units Involved in Derived Units

Let’s take a few derived units and break them down:

  1. Velocity (m/s)

    • Derived from: metre (m) / second (s)

  2. Acceleration (m/s²)

    • Derived from: (metre/second) / second = m/s²

  3. Force (Newton, N)

    • Formula: F = ma (mass × acceleration)

    • So, unit = kg × m/s² = kg·m/s²

  4. Energy (Joule, J)

    • Formula: Work = Force × Distance

    • Unit = (kg·m/s²) × m = kg·m²/s²
