Study Notes
Unit 1: Introduction to Biology, Anatomy, and Physiology
- Biology studies all living things
- Anatomy studies the physical structures of organisms
- Physiology studies how structures function
Organization of Living Things
- Genetic variation is crucial for species survival
- Genetic variation allows populations to adapt to changing environments, like exposure to antibacterial substances
- Organisms are categorized into 6 kingdoms based on similarities in characteristics (single/multi-celled, prokaryotic/eukaryotic, environmental adaptations, movement, energy acquisition)
- There are approximately 8.7 million known species on Earth
- Students should familiarize themselves with examples for each kingdom
Organization of the Human Body
- Anatomical terms describe the position and location of body parts
- Directional terms, like superior/inferior, anterior/posterior, proximal/distal, medial/lateral, superficial/deep, are used to precisely describe body locations
- Body planes (midsagittal, parasagittal, frontal, transverse, oblique) section the body for study
- Body cavities (cranial, vertebral, thoracic, abdominal, pelvic) house or contain major organs
- Abdominopelvic regions and quadrants further divide the body for specific anatomical study
- Anatomical position provides a standard perspective for describing the human body
Properties of Living Things
- Living organisms share fundamental properties
- Basic elements (C, O, H, N) are essential for life
- Metabolism is the transfer of energy from one form to another (e.g., converting ATP into movement)
- Evolution is dependent on the environment
Unit 2: The Molecules of Life
Water
- Water is the main component of all living organisms (infants ~75%, adult men ~60%, adult women ~55%)
- Water's unique properties make it an ideal solvent in living organisms
- Water molecules are polar/hydrophilic
- Water repelling substances are nonpolar/hydrophobic
Macromolecules (4 types)
- Polymers are formed by the process of dehydration synthesis
- Proteins are polymers of amino acids
- Proteins are responsible for a variety of functions, and have different structures
Nucleic Acids
- DNA is a polymer of nucleotides
- DNA's structure is a double helix
Carbohydrates
- Carbohydrates provide energy and serve structural roles
- Monosaccharides (glucose, fructose, galactose) are the simplest sugars
- Disaccharides are formed by combining monosaccharides (e.g., lactose, sucrose, maltose)
- Polysaccharides are complex carbohydrates (e.g., starch, glycogen, cellulose)
Lipids
- Lipids serve for energy storage, structural components, and signaling
- Triglycerides consist of fatty acids and glycerol
- Lipids are associated with saturated (solid at room temperature), unsaturated (liquid), and trans fats
- Essential types of fatty acids include Omega-3 and Omega-6
- Phospholipids are amphipathic molecules essential for cell membranes
