Brain vs Computer
• Both tremendous capacity to store information
• Computer can easily retrieve information due to software
designed to organize information storage that allows for
fast and easy retrieval.
• Our brains have same capacity but we have to “program”
the brain to retrieve
• “Basket of socks” analogy - connections create
organization
Chapter 1
Introduction to Human Anatomy and
Physiology
Expanding your knowledge base!
• “jungle gym analogy”
1. Comprehension – ability to read or hear → understand
2. Study skills – reading rate, memorization aptitude, “brain hooks - socks”
3. Discipline – preview chapters, studying material on daily basis outside of class
4. Organization – notes, flash cards, lists, drawings, reviews
5. Prior knowledge base – previous courses in college or high school
6. Hard work – hours put in if not proficient in basics – plan now!
7. Correlate material – acronyms, analogies, personalize
8. Study partners or groups – 2 or more viewpoints clears understanding

Lecture tests make up 70% of grade!
Attend classes – penalty if over 4 misses
Do chapter summaries
Do chapter review exercises (bonus)
Turn in all articles – 10 in 12 weeks
Pass all open book/notes quizzes (>70%) – are pass or fail
Give blood and do community service project
Study bonus questions given out before tests – 8 to 10
given for each test but only 2 on each lab or lecture test
9. Participate in class
Anatomy and Physiology
Anatomy
– study of structure
Physiology
– study of function
Structure is always related to function
1-3
Levels of Organization
1-5
Levels of Organization
“Building blocks of the organism”
Atom – hydrogen, carbon, nitrogen, oxygen atoms
Molecule – water , glucose, NaCl molecules
Macromolecule – protein molecule, DNA molecule
Organelle – mitochondria, Golgi apparatus, ribosome,
lysosome, cell membrane, nucleus
Cell – muscle cell, nerve cell, bone cell- (70 trillion)
Tissue – bone tissue, muscle tissue, nerve tissue
Organ – skin, femur, heart, kidney, liver
Organ System – skeletal system, digestive system,
integumentary system, circulatory system
1-4
Organism – human, cat, dog
Table 1.3, p. 8
Characteristics of Life - 10
1) Movement – change in position; motion – inside and outside
2) Responsiveness – reaction to a change
3) Growth – increase in size
4) Reproduction – production of new organisms and new cells
5) Respiration – obtaining oxygen; removing
carbon dioxide; releasing energy from foods
1-6
Characteristics of Life
6) Digestion – breakdown of food substances
7) Absorption – passage of substances through
membranes and into body fluids
8) Circulation – movement of substances in body fluids
9) Assimilation – changing of absorbed substances into
different substances
10) Excretion – removal of wastes
1-7
Metabolism
• Physical and chemical events that release and
utilize energy
• All the previous characteristics of life involve
metabolism
Table 1.4, p. 9
Requirements of Organisms
Water
- most abundant substance in body
- required for metabolic processes
- required for transport
- regulates body temperature
Food
- supply energy
- supply raw materials
1-8
Requirements of Organisms
Oxygen
- one-fifth of air
- used to release energy from nutrients
Heat
- form of energy
- partly controls rate of metabolic reactions
Pressure
- atmospheric pressure (exerted by gas) – important for breathing
- hydrostatic pressure (exerted by fluids) – keeps blood flowing
1-9
Homeostasis
“Body’s maintenance of a stable internal environment”
Homeostatic Mechanisms – monitor aspects of the internal environment
and corrects any changes
•Receptors - provides information about internal and external
environment
•Control center - tells what a particular value should be and
processes a response to information
•Effectors - causes response to change of internal environment
•Positive feed back – promote frequency & intensity of
process – ie ↑ breathing rate with exercise
•Negative feedback – reverses trend of process – ie rising
internal body temperature above 98.6 F
Homeostatic Mechanisms
1-11
Body Cavities
Thoracic cavity = pleural cavity (lungs) + mediastinum (heart, esophagus, thymus, trachea)
↓
Diaphram
↓
Abdominopelvic cavity = abdominal cavity (stomach, pancreas, liver, spleen, gallbladder, large and small intestine
+
pelvic cavity (terminal large intestine, urinary bladder, reproductive organs)
1-12
Serous Membranes
Visceral layer – covers an organ
Parietal layer – lines a cavity or body wall-”guards perimeter”
Thoracic Membranes
Visceral pleura (lungs)
Parietal pleura (lungs)
Visceral pericardium (heart)
Parietal pericardium (heart)
Abdominopelvic Membranes
• Visceral peritoneum
• Parietal peritoneum

Anatomical Terminology
Anatomical Position – body standing erect, facing forward, upper
limbs at the sides, palms facing forward
Terms of Relative Position
•Superior versus Inferior – top vs bottom
•Anterior versus Posterior – front vs back of structure
•Medial versus Lateral – middle vs away from middle of structure
•Ipsilateral versus Contralateral – same side vs opposite side
•Proximal versus Distal – closer to body vs away from body –
usually associated with extremities
•Superficial versus Deep – near surface vs more internal
↓
•Peripheral – outward from central structure or near surface 1-18
Body Sections
•Sagittal / Median-leave left & right portions
•Transverse / Cross- leave top & bottom portions
•Coronal or Frontal- leave front & back portions
•Oblique-cut at angle in any of the planes
1-19
Abdominal Subdivisions
Vertical line – through center of breast
Horizontal line – 11th rib & ASIS of pelvis
Locate:
“Cross hairs” on navel
liver, gall bladder, stomach, pancreas, large intestine, small intestine, spleen, diaphram, urinary bladder
