Study Notes
Cell Biology
- Cells are the basic structural and functional units of all living organisms.
- There are two main types of cells: prokaryotic and eukaryotic.
- Prokaryotic cells lack a nucleus and other membrane-bound organelles.
- Eukaryotic cells have a nucleus and other membrane-bound organelles, such as mitochondria, endoplasmic reticulum, and Golgi apparatus.
- Cells maintain homeostasis through various processes, including respiration, metabolism, and reproduction.
- Cell membranes are selectively permeable, regulating the movement of substances into and out of the cell.
- Cellular communication is crucial for coordinating activities within an organism.
- Cell division (mitosis and meiosis) allows for growth, repair, and reproduction.
- Specialized cells perform specific functions within tissues and organs.
Human Anatomy
- Human anatomy refers to the study of the structures of the human body.
- The body is comprised of various organ systems working together towards maintaining homeostasis.
- The skeletal system provides support and protection, while the muscular system facilitates movement.
- The nervous system is responsible for communication and coordination, controlling various functions.
- The circulatory system, including the heart and blood vessels, transports oxygen and nutrients throughout the body.
- The respiratory system facilitates gas exchange (oxygen intake and carbon dioxide release).
- The digestive system processes food for absorption of nutrients.
- The endocrine system regulates bodily functions using hormones.
- The immune system protects against disease.
- The excretory system removes waste products from the body.
Biochemistry
- Biochemistry is the study of the chemical processes within and relating to living organisms.
- It involves the study of biomolecules like carbohydrates, lipids, proteins, and nucleic acids.
- Carbohydrates serve as a primary source of energy and structural components.
- Lipids store energy, form cellular membranes, and act as signaling molecules.
- Proteins are involved in numerous functions including catalysis, structural support, and transport.
- Nucleic acids (DNA and RNA) store and transmit genetic information.
- Metabolism encompasses all chemical reactions within a cell, including catabolism (breakdown) and anabolism (synthesis).
- Enzymatic reactions are crucial for controlling metabolic pathways.
- Biochemical processes are fundamental to life.
Human Anatomy/Physiology Overlap
- Physiology studies how the body functions, while anatomy studies its structure.
- A thorough understanding of anatomy is crucial for comprehending physiological processes.
- The function of each organ system is intimately linked to its structure.
- Concepts like homeostasis, feedback loops, and transport mechanisms are fundamental to both.
