Study Notes
Overview of Workshops
- Workshops aim to reinforce online module concepts.
- Participation enhances learning; respect and allow contributions.
Assessment Information
- Assessment 1: Professional Case Studies (40% total)
- Three case studies, each worth 10 marks.
- Conducted during lab classes (20 minutes each).
- Pre-class online module completion is vital.
- Assessment 2: Mid Semester Exam (20%).
- Assessment 3: Final Theory Exam (40%).
Professional Case Studies
- Assessment heavily emphasizes participation (10% total).
- Evaluated on practical engagement, professional behavior, and reflective ability.
Body Organ Systems
- Recognized systems include:
- Integumentary, Skeletal, Muscular, Lymphatic, Respiratory, Digestive, Nervous, Endocrine, Cardiovascular, Urinary, and Reproductive systems.
- Functions matched to systems:
- Lymphatic: Returns fluid to blood.
- Digestive: Breaks down food for nutrient distribution.
- Urinary: Removes nitrogenous waste via urine.
- Muscular: Facilitates body movement.
- Integumentary: Regulates temperature and excretes salts.
- Endocrine: Glands secrete hormones for regulation.
Survival Needs of Humans
- Nutrients: Needed for energy and cell growth.
- Oxygen: Essential for energy release from food.
- Water: Basis for various body fluids, including blood plasma.
- Normal body temperature: Influences the rate of chemical reactions.
- Atmospheric pressure: Affects airflow in and out of lungs.
Cell Physiology
- Diffusion: Movement of solutes from high to low concentration.
- Osmosis: Water movement from dilute to concentrated solutions through membranes.
-
Simple vs. Facilitated Diffusion:
- Simple diffusion: Unassisted movement across the plasma membrane (e.g., lipids, oxygen, carbon dioxide).
- Facilitated diffusion: Assisted movement via carrier or channel proteins (e.g., glucose, amino acids, ions).
Homeostasis
- Homeostatic control components:
- Receptors detect changes.
- Control center processes signals.
- Effectors execute responses to restore balance.
- Negative feedback reduces the original stimulus (e.g., parathyroid hormone regulates calcium levels).
- Positive feedback enhances the response to a stimulus (e.g., oxytocin during childbirth).
Activities for the Week
- Attend allocated practical classes.
- Complete Week 2 Online Module.
- Finish Health and Safety Quiz for lab access next week.
