I. Introduction to Anatomy and Physiology

Anatomy is the study of the structure of the body, from the macroscopic level (organs and organ systems) down to the microscopic level (cells and tissues). Physiology, on the other hand, focuses on the function of these structures and how they work together to maintain life. Understanding the relationship between structure and function is crucial in A&P. For instance, the structure of the lungs – their large surface area and thin membranes – is perfectly suited to their function of gas exchange.

Key Concepts to Include in your Quizlet:

• Levels of Organization: Chemical, Cellular, Tissue, Organ, Organ System, Organism. Understand the hierarchical nature of these levels and be able to provide examples.
• Anatomical Terminology: Mastering directional terms (superior, inferior, anterior, posterior, medial, lateral, proximal, distal) and regional terms is essential for accurately describing body locations. Practice using these terms in sentence constructions.
• Body Planes and Sections: Learn to identify sagittal, frontal (coronal), and transverse planes and understand how they are used to visualize internal structures.
• Body Cavities: Familiarize yourself with the dorsal (cranial and vertebral) and ventral (thoracic and abdominopelvic) cavities and their subdivisions. Knowing the organs housed within each cavity is important.
• Homeostasis: This is a central theme in physiology. Understand the concept of maintaining a stable internal environment despite external changes and the mechanisms involved in negative feedback loops. Think of examples like body temperature regulation and blood glucose control.

II. Cellular Level of Organization

The cell is the basic unit of life. A thorough understanding of cell structure and function is paramount in A&P 1.

Key Concepts for your Quizlet:

• Cell Membrane: Focus on its structure (phospholipid bilayer, proteins, cholesterol) and functions (selective permeability, transport mechanisms like diffusion, osmosis, active transport). Understand the difference between passive and active transport.
• Cytoplasm and Organelles: Learn the structure and function of each organelle: nucleus (DNA replication, gene expression), ribosomes (protein synthesis), endoplasmic reticulum (protein and lipid synthesis), Golgi apparatus (modification and packaging of proteins), mitochondria (ATP production), lysosomes (waste breakdown), and peroxisomes (lipid metabolism).
• Cellular Respiration: This is a crucial metabolic process that provides energy (ATP) for cellular functions. Understand the different stages (glycolysis, Krebs cycle, electron transport chain) and the role of oxygen.
• Protein Synthesis: Learn the steps involved in transcription (DNA to mRNA) and translation (mRNA to protein). Understand the role of ribosomes, tRNA, and mRNA in this process.
• Cell Division: Study mitosis (cell replication for growth and repair) and meiosis (cell division for sexual reproduction). Understand the differences between these two processes.

III. Tissue Level of Organization

Tissues are groups of similar cells that perform a specific function. Four primary tissue types exist:

Key Concepts for your Quizlet:

• Epithelial Tissue: Learn the different types (covering and lining epithelium, glandular epithelium) and their characteristics (cellularity, specialized contacts, polarity, support, avascularity, regeneration). Understand the functions of different epithelial types (protection, secretion, absorption, excretion).
• Connective Tissue: This diverse tissue type includes bone, cartilage, adipose tissue, and blood. Learn the different types of connective tissues and their characteristics (extracellular matrix, cell types). Understand the functions of each type (structural support, binding, insulation, transport).
• Muscle Tissue: There are three types: skeletal (voluntary movement), smooth (involuntary movement in internal organs), and cardiac (heart muscle). Understand the structural and functional differences between these types.
• Nervous Tissue: This tissue is specialized for communication. Learn about neurons (transmitting signals) and neuroglia (supporting cells). Understand the basic structure of a neuron (cell body, dendrites, axon).

IV. Organ Systems

Organ systems are groups of organs that work together to perform a specific function. A&P 1 typically covers several major organ systems:

Key Concepts for your Quizlet (Organize by System):

• Integumentary System: Skin, hair, nails. Functions: protection, temperature regulation, sensation. Learn about the layers of the skin (epidermis, dermis, hypodermis) and their components.
• Skeletal System: Bones, cartilage, ligaments. Functions: support, protection, movement, blood cell production, mineral storage. Learn the types of bones and bone markings.
• Muscular System: Skeletal muscles, tendons. Functions: movement, posture, heat production. Understand the different types of muscle contractions (isotonic, isometric).
• Nervous System: Brain, spinal cord, nerves. Functions: control and coordination of body functions, sensory perception. Learn the basic organization of the nervous system (central and peripheral). Understand neuron structure and function (action potentials, neurotransmitters).
• Endocrine System: Hormone-producing glands. Functions: regulation of body functions through hormones. Learn the major endocrine glands (pituitary, thyroid, adrenal, pancreas) and the hormones they produce.
• Cardiovascular System: Heart, blood vessels, blood. Functions: transport of oxygen, nutrients, hormones, and waste products. Understand the structure of the heart and the flow of blood through the circulatory system.
• Lymphatic System: Lymph nodes, lymphatic vessels, spleen. Functions: immune response, fluid balance.
• Respiratory System: Lungs, trachea, bronchi. Functions: gas exchange (oxygen and carbon dioxide). Understand the mechanics of breathing and gas exchange in the alveoli.
• Digestive System: Mouth, esophagus, stomach, intestines, liver, pancreas. Functions: breakdown and absorption of food. Learn the different stages of digestion and the role of digestive enzymes.
• Urinary System: Kidneys, ureters, bladder, urethra. Functions: excretion of waste products, regulation of fluid balance and electrolyte balance. Understand the process of urine formation.

V. Explanation of Key Physiological Processes

Beyond simply knowing the structures and organs, understanding how these systems function is crucial. This section highlights key physiological processes to include in your Quizlet:
