Study Notes
Health Promotion
Definition
- Health promotion is the process of enabling people to increase control over and improve their health.
- It involves a range of social, environmental, and political interventions to promote health and well-being.
Key Concepts
- Health Education: the process of informing people about healthy behaviors and lifestyles.
- Health Advocacy: promoting the interests of individuals or groups to improve their health.
- Health Empowerment: enabling people to take control of their health and make informed decisions.
Principles of Health Promotion
- Participation: involving individuals and communities in the health promotion process.
- Equity: promoting health equity and reducing health inequalities.
- Holism: considering the physical, emotional, and social aspects of health.
- Sustainability: promoting long-term health and well-being.
Health Promotion Strategies
- Downstream: focusing on individual behavior change (e.g., health education).
- Midstream: targeting social and environmental factors that influence health (e.g., policy change).
- Upstream: addressing the root causes of health problems (e.g., social determinants of health).
Settings for Health Promotion
- Community: promoting health in community settings, such as schools and workplaces.
- Healthcare: promoting health in healthcare settings, such as hospitals and clinics.
- Workplace: promoting health in the workplace, such as through employee wellness programs.
Health Promotion Theories
- Social Cognitive Theory: people learn new behaviors by observing and imitating others.
- Theory of Planned Behavior: people's intentions and behaviors are influenced by their attitudes, subjective norms, and perceived behavioral control.
- Health Belief Model: people's health behaviors are influenced by their perceived susceptibility, severity, benefits, and barriers to health.

Cellular Structure and Function
- Cell membrane is semi-permeable, regulating what enters and leaves the cell, and is composed of a phospholipid bilayer with embedded proteins.
- Functions of the cell membrane include:
- Regulating transport of molecules in and out of the cell
- Maintaining cell shape and structure
- Providing mechanical support and protection
Cellular Organelles
- Nucleus contains genetic material (DNA) and is responsible for controlling cellular activities.
- Mitochondria generates energy for the cell through cellular respiration.
- Endoplasmic Reticulum (ER) is involved in protein synthesis and transport.
- Ribosomes are the site of protein synthesis.
- Lysosomes contain digestive enzymes for cellular recycling.
- Golgi Apparatus is involved in protein modification and packaging.
Cellular Processes
- Metabolism involves chemical reactions that occur within the cell to maintain homeostasis.
- Photosynthesis is the process by which cells convert light energy into chemical energy.
- Cellular Respiration is the process by which cells generate energy from glucose.
- Cell Division is the process by which cells replicate and divide.
Human Body Systems
Nervous System
- Central Nervous System (CNS) consists of the brain and spinal cord.
- Peripheral Nervous System (PNS) consists of nerves that connect CNS to the rest of the body.
- Functions of the Nervous System include:
- Controlling and coordinating body functions
- Interpreting and responding to sensory information
Circulatory System
- Heart pumps blood throughout the body.
- Blood Vessels consist of arteries, veins, and capillaries that transport blood.
- Functions of the Circulatory System include:
- Delivering oxygen and nutrients to cells
- Removing waste products from cells
Immune System
- Defends the body against pathogens and foreign substances.
- Components of the Immune System include:
- White blood cells (leukocytes)
- Lymphatic vessels and organs (spleen, lymph nodes, etc.)
Digestive System
- Mouth is responsible for mechanical breakdown of food.
- Stomach is responsible for chemical breakdown of food.
- Small Intestine is responsible for absorption of nutrients.
- Functions of the Digestive System include:
- Breaking down food into nutrients
- Absorbing nutrients into the bloodstream
Genetics
DNA Structure
- DNA has a double helix model, consisting of two complementary strands of nucleotides.
- Nucleotides are composed of sugar, phosphate, and nitrogenous bases (A, C, G, and T).
- The sequence of nucleotides determines the amino acid sequence, which is known as the Genetic Code.
Inheritance Patterns
- Mendelian Inheritance describes the laws of inheritance that determine how traits are passed down.
- Autosomal Dominant traits are expressed when one copy of the dominant allele is present.
- Autosomal Recessive traits are expressed when two copies of the recessive allele are present.
Genetic Variation
- Mutations are changes in the DNA sequence.
- Genetic Drift is the random change in gene frequencies.
- Gene Flow is the movement of genes from one population to another.
