Study Notes
Organ Systems in the Human Body
- The human body consists of several organ systems, each with a unique function, including:
- Nervous system: controls and coordinates body functions
- Circulatory system: transports oxygen and nutrients to cells
- Respiratory system: takes in oxygen and expels carbon dioxide
- Digestive system: breaks down food into nutrients
- Endocrine system: produces hormones to regulate body functions
- Immune system: defends the body against pathogens
- Muscular system: enables movement and maintains posture
- Skeletal system: provides support and protection
- Integumentary system: protects the body from external damage
- Urinary system: filters waste and excess fluids
- Reproductive system: produces sex cells and supports reproduction
Cellular Structure
- A cell is often referred to as the "basic unit of life"
- The cell wall was discovered by Robert Hooke in 1665
Microscopy
- A microscope is required to study or observe cells because cells are microscopic in size
- Microscopes enable scientists to visualize and examine cells in detail
Cellular Analogy
- The relationship between cells and the human body is often described as "a city with many buildings"
- In this analogy, cells represent the individual buildings, while the human body represents the city as a whole
