Chapter 1: Introduction to Anatomy and Physiology
1. Definition and Scope
● Anatomy = Study of the structure of the body and its parts.
○ Gross Anatomy: Visible structures (organs, tissues)
○ Microscopic Anatomy: Cells and tissues (histology)
● Physiology = Study of function — how the body works.
○ Often linked with anatomy (structure determines function).
2. Levels of Organization
From smallest to largest:
1. Chemical level – Atoms and molecules (e.g., H2O, proteins)
2. Cellular level – Cells are the basic unit of life
3. Tissue level – Groups of similar cells performing a function
4. Organ level – Structures made of different tissues (e.g., heart)
5. Organ system level – Groups of organs working together (e.g., circulatory system)
6. Organismal level – Whole body functioning as a unit
,3. Homeostasis
● Definition: The body’s ability to maintain a stable internal environment.
● Mechanisms:
○ Receptor → Detects change (stimulus)
○ Control Center → Brain or endocrine gland interprets signal
○ Effector → Organ or tissue acts to restore balance
Example: Body temperature regulation
● Receptor: Thermoreceptors in skin detect heat
● Control Center: Hypothalamus interprets
● Effector: Sweat glands activated → cooling
4. Negative vs Positive Feedback
● Negative Feedback: Counteracts change (most common)
○ Example: Blood glucose regulation by insulin/glucagon
● Positive Feedback: Amplifies change (less common)
○ Example: Oxytocin during labor contractions
5. Anatomical Terminology
● Directional terms: Superior, inferior, anterior, posterior, medial, lateral, proximal, distal
● Body planes: Sagittal, coronal (frontal), transverse
● Body cavities: Cranial, thoracic, abdominal, pelvic
● Quadrants for abdominal organs: RUQ, LUQ, RLQ, LLQ
6. Basic Life Processes
1. Metabolism – All chemical reactions in the body
2. Responsiveness – Ability to detect and respond to stimuli
3. Movement – Muscles, blood flow, cellular transport
4. Growth – Increase in size or number of cells
5. Differentiation – Unspecialized cells become specialized
6. Reproduction – Cellular (mitosis) or organismal (sexual reproduction)
, 7. Key Concept Connections
● Structure ↔ Function: The way something is built affects what it can do.
● Homeostasis ↔ Health: Disruption leads to disease.
● Levels of organization ↔ Complexity: From atoms → human organism.
Quick Check Questions (with answers)
1. Q: What is the main difference between anatomy and physiology?
A: Anatomy = structure; Physiology = function
2. Q: Give an example of negative feedback.
A: Regulation of blood glucose by insulin and glucagon
3. Q: What are the levels of organization from simplest to most complex?
A: Chemical → Cellular → Tissue → Organ → Organ system → Organism
4. Q: What is homeostasis?
A: Maintaining a stable internal environment
5. Q: Name the body planes.
A: Sagittal, coronal (frontal), transverse
Chapter 2: The Chemical Level of Organization
1. Matter and Elements
● Matter = Anything that occupies space and has mass
● Elements = Pure substances that cannot be broken down chemically
○ Major elements in the body (96% of mass): Oxygen (O), Carbon (C),
Hydrogen (H), Nitrogen (N)
○ Minor elements (3.6%): Calcium (Ca), Phosphorus (P), Potassium (K), Sulfur
(S), Sodium (Na), Chlorine (Cl), Magnesium (Mg)
○ Trace elements (<0.01%): Iron (Fe), Zinc (Zn), Iodine (I), etc.
2. Atoms and Atomic Structure
● Atom: Smallest unit of an element with unique properties
● Subatomic particles:
○ Protons (p⁺): Positive, in nucleus
○ Neutrons (n⁰): Neutral, in nucleus
○ Electrons (e⁻): Negative, orbit nucleus
