Study Notes
Introduction to Biology
- Biology studies life from various aspects, focusing on both living organisms and their environments.
- Includes specialized fields like morphology, physiology, anatomy, and behavior.
Branches of Biology
- Anatomy: Studies the structure of organisms and their parts.
- Histology: Focuses on the microscopic structure of tissues.
- Cytology: Examines cellular structure and function.
- Physiology: Investigates normal functions of living organisms and their systems.
- Embryology: Studies the development and growth of embryos.
- Genetics: Analyzes inherited characteristics and variations.
- Molecular Biology: Studies biological molecules such as DNA and RNA.
- Biochemistry: Investigates chemical processes and reactions in organisms.
- Zoology: Scientific study of animals' behavior, structure, and classification.
- Botany: Focuses on the study of plants.
- Microbiology: Examines microorganisms.
- Evolution: Studies the development of species over time.
- Ecology: Investigates relationships between organisms and their environments.
- Entomology: Studies insects.
Human Biology
- Examines human anatomy and activities including growth, nutrition, reproduction, and respiration.
- Focuses on anatomy, physiology, histology, and embryology.
- Physiological study emphasizes organs and systems functioning together to maintain homeostasis.
Organization of the Human Body
- Human body organization ranges from cells to the entire organism, indicating increasing complexity.
- Key elements: hydrogen, oxygen, carbon, calcium, and phosphorus compose trillions of cells.
- Major electrolytes: sodium and chloride in body water, potassium in cells.
Cells
- Cells are the fundamental units of structure and function, essential for survival.
- Specialized cells, like nerve and muscle cells, perform distinct roles, such as transmitting messages and providing energy for movement.
Tissues
- Tissues are groups of similar cells serving specific functions.
- Four basic tissue types in the human body:
- Epithelial: Protects (e.g., skin).
- Connective: Supports (e.g., bones).
- Muscular: Facilitates movement (e.g., skeletal muscle).
- Nervous: Enables communication (e.g., brain).
Organs and Organ Systems
- Organs are comprised of different tissue types, e.g., brain, heart, lungs.
- Organ systems consist of groups of organs working together for complex functions.
Major Organ Systems
- Cardiovascular System: Heart and blood vessels transport oxygen and nutrients.
- Lymphatic System: Lymph nodes and vessels defend against disease.
- Digestive System: Involves esophagus and intestines for food digestion and nutrient absorption.
- Endocrine System: Glands produce hormones for cellular communication.
- Integumentary System: Skin, hair, and nails protect against injury and infection.
- Muscular System: Involved in movement and heat generation.
- Nervous System: Processes information, involving the brain and nerves.
- Reproductive System: Produces gametes and hormones for reproduction.
- Respiratory System: Trachea and lungs facilitate gas exchange.
- Skeletal System: Provides support and protection, and produces blood cells.
