Anatomy Overview Quiz

Anatomy

• Definition: Study of the structure and organization of living organisms.

• Types:

  1. Gross Anatomy: Structures visible to the naked eye (e.g., organs, tissues).
  2. Microscopic Anatomy: Structures that require a microscope to be seen (e.g., cells, tissues).

• Organ Systems:

  1. Skeletal System: Composed of bones; provides structure and support.
  2. Muscular System: Comprised of muscles; facilitates movement.
  3. Nervous System: Controls body activities through nerve impulses; includes brain, spinal cord, nerves.
  4. Cardiovascular System: Heart and blood vessels; responsible for transport of blood, nutrients, and gases.
  5. Respiratory System: Organs involved in breathing; includes lungs and trachea.
  6. Digestive System: Processes food and absorbs nutrients; includes mouth, stomach, intestines.
  7. Endocrine System: Glands that secrete hormones; regulates various bodily functions.
  8. Lymphatic System: Supports immune function; includes lymph nodes and vessels.
  9. Urinary System: Eliminates waste; consists of kidneys, ureters, bladder, urethra.
  10. Reproductive System: Produces offspring; different structures in males and females.

Physiology

• Definition: Study of the functions and processes of the body's systems and organs.

• Key Concepts:

  1. Homeostasis: Maintenance of stable internal conditions despite external changes.
  2. Metabolism: Chemical processes within the body; includes catabolism (breakdown) and anabolism (building up).
  3. Cellular Physiology: Study of cell functions; includes processes such as cell metabolism, signaling, and communication.

• Processes:

  1. Respiration: Exchange of gases (oxygen and carbon dioxide) in cells and with the environment.
  2. Circulation: Movement of blood through the heart and vessels to supply oxygen and nutrients.
  3. Digestion: Breakdown of food into smaller molecules for nutrient absorption.
  4. Excretion: Removal of waste products from metabolism and other non-useful materials.

• Feedback Mechanisms:

  1. Negative Feedback: Responds to changes in a system to return to a set point (e.g., temperature regulation).
  2. Positive Feedback: Enhances and increases the output of a process (e.g., childbirth).

Integration of Anatomy and Physiology

• Structure and function are interconnected; the anatomy of a structure influences its physiological role.
• Examples:
  • Heart chambers (anatomy) support the pumping function (physiology).
  • Alveoli in lungs (structure) facilitate gas exchange (function).
