Physiology
Physiology is the branch of biology that deals with the normal functions of living organisms and their parts. It is the study of how the body works and how its different systems function together to maintain homeostasis.
Key Concepts
- Homeostasis: The ability of the body to maintain a stable internal environment despite external changes.
- Cellular Physiology: The study of the functions of cells, including metabolism, communication, and reproduction.
- Organ System Physiology: The study of how different organ systems (e.g. respiratory, circulatory, nervous) work together to maintain the body's functions.
- Neurophysiology: The study of the nervous system and how it controls and coordinates the body's activities.
- Cardiovascular Physiology: The study of the heart and blood vessels, and how they function to transport nutrients, oxygen, and waste products throughout the body.
Study Tips
- Understand the basic concepts of biology and chemistry, as they form the foundation of physiology.
- Make use of diagrams and visual aids to understand the complex systems and processes involved in physiology.
- Practice active learning by using flashcards, quizzes, and practice exams to test your understanding.
- Seek out additional resources such as textbooks, online lectures, and educational videos to supplement your learning.
- Form study groups to discuss and review concepts with your peers.
Common Questions
- What is the difference between anatomy and physiology?
- How does the body maintain homeostasis?
- What are some common disorders related to physiological processes?
Anatomy focuses on the structure of living organisms and their parts, while physiology focuses on the functions and processes of those parts.
The body maintains homeostasis through mechanisms such as negative feedback loops, which regulate internal conditions to keep them within a narrow range.
Examples include diabetes (related to the endocrine system), hypertension (related to the cardiovascular system), and asthma (related to the respiratory system).
