Study Notes
Course Resources
- Recommended textbooks include Berne and Levy Physiology, Guyton and Hall Textbook of Medical Physiology, and Medical Biochemistry.
- Canvas serves as the main platform for course-related materials, including timetables, lecture notes, and assessments.
Course Assessment and Workload
- Expect to invest 120-140 hours per 10-unit course; full-time study equates to 40 hours per week for four courses.
- Contact the program convenor for assistance with managing commitments outside of university studies.
- Mid-semester and formal assessments managed online; documentation required for adverse circumstances should match impact dates.
Homeostasis and Fluid Compartments
- Two main fluid compartments:
- Intracellular fluid (ICF) within cells.
- Extracellular fluid (ECF) which includes interstitial and plasma fluid outside cells.
- Normal composition values for ECF include core body temperature (37°C), pH (7.35-7.45), and blood glucose (70-110 mg/dl).
Homeostatic Mechanisms
- Regulation primarily involves the nervous and endocrine systems, often operating through negative feedback loops.
- Homeostatic feedback system components include receptors (sensors), control centers, and effectors that work to maintain equilibrium.
Importance of Water
- Water is unique due to its polar covalent bonds, which facilitate hydrogen bonding.
- Chemical reactions in the body occur in water, making the understanding of its properties essential to physiological processes.
Chemical Interactions
- Atoms can lose or gain electrons; those that lose become cations (positive charge, e.g., Na+) and those that gain become anions (negative charge, e.g., Cl-).
- Ionic bonds form through electrical attraction between cations and anions.
Organic vs. Inorganic Compounds
- Organic compounds contain carbon and are characteristic of living organisms (e.g., carbohydrates, lipids, proteins).
- Inorganic compounds do not typically contain carbon but include water, oxygen, nitrogen, and essential ions.
Key Concepts
- Understanding atomic interactions is crucial for grasping how larger molecules like carbohydrates and proteins form.
- Hydrogen bonds significantly influence the molecules' shapes, vital for drug and hormone functioning.
- Knowledge of anions and cations is foundational for future discussions on plasma components and physiological processes.
