Study Notes
Anatomy and Physiology Concepts
- Epiglottis: Structure that prevents food from entering the airway during swallowing.
- Cartilage: Provides support and cushioning between vertebrae.
- Epithelial tissue classification: Based on two criteria—cell layers and cell shape.
- Parathyroid gland: Located in the neck, regulates calcium levels in the body.
- Organ systems in human body: There are 11 distinct organ systems.
Systems and Functions
- Cilia: Tiny hair-like structures in the respiratory system that remove foreign particles from lungs.
- Diffusion: Process in lungs by which oxygen passes from air into the bloodstream.
- Integumentary system: Blocks pathogens and helps in synthesizing vitamin D.
- Nervous system: Acts as the body’s communication center, regulating functions and responses.
- Endocrine system: Primarily responsible for hormone regulation throughout the body.
Respiratory and Circulatory Relationships
- Path of Oxygenated Blood: From the pulmonary veins to the left atrium, then through the mitral valve to the left ventricle.
- Functions of the circulatory system: Removal of excess heat via integumentary components.
- Heart structure: The left ventricle is the most muscular chamber, responsible for pumping oxygenated blood.
Genetic Basic Concepts
- Genes: Basic unit of heredity, crucial for trait inheritance.
- Antigen: Substance that stimulates antibody production.
- DNA vs. RNA: DNA contains thymine, whereas RNA contains uracil; both are critical for genetic information.
Cellular Biology
- Mitochondria: Often referred to as the cell's power house, providing energy for functions.
- Ribosomes: Key role in protein synthesis within cells.
- Meiosis vs. Mitosis: Meiosis results in genetically diverse cells, while mitosis produces identical cells.
Immune and Excretory System
- Plasma cells: Secrete antibodies as a response to antigens.
- Spleen: Includes the filtering of microorganisms and foreign substances from blood.
- Sweat glands: Integral for body temperature regulation in the excretory system.
Chemical Processes
- Acidic substance: Defined by a pH of less than 7.
- Catalysts: Substances that alter the activation energy to control chemical reactions.
- Chemical bond types: Ionic bonds form from electron transfer, while covalent bonds connect atoms by sharing electrons.
Additional Key Points
- Tachycardia: Condition where heart rate exceeds 100 beats per minute.
- Valves in the heart: Tricuspid valve allows blood from the right atrium to flow into the right ventricle.
- Condition of electrons: An atom with 5 protons and 6 electrons is negatively charged.
Summary of Body Systems
- Respiratory system: Takes in oxygen and expels carbon dioxide, facilitating gas exchange in alveoli.
- Immune system: Contributes to illness defense and produces antibodies.
- Circulatory system components: Comprises the heart, blood, and blood vessels integral to bodily functions.
Measurement and Properties
- Triple beam balance: Measurement unit in grams.
- Crystalline order: Describes the structured arrangement of molecules in solid materials.
- Vaporization: The process of a substance changing from liquid to gas.
