1. INTRODUCTION TO HUMAN ANATOMY AND PHYSIOLOGY

2. Anatomy – the structure of body parts (also called Morphology) Physiology – the function of the body parts, what they do and how they do it Gross Anatomy- study of body parts visible to the naked eye Tissue- group of similar cells that perform a common function DEFINITIONS

3. Organ- group of several tissue types that together perform a special function Organ Systems- a group of organs working together to carry out a particular task Hypothesis- idea or scientific concept propose as a possible explanation of nature Anatomical Positions- specific body position that is used universally as a common reference point for the positions of body structures Body Planes- transparent glasslike plates dividing the body into parts which represent cuts or sections that can be made along a particular line of orientation

4. MORE ANATOMICAL VOCABULARY BODY CAVITIES- ANY SPACE IN THE BODY THAT CONTAINS ORGANS OR FLUID CELL - THE SMALLEST AND MOST NUMEROUS STRUCTURAL UNITS THAT POSSESS AND EXHIBIT THE BASIC CHARACTERISTICS OF LIVING MATTER SOMATOTYPE: USED TO DESCRIBE A PARTICULAR CATEGORY OF BODY BUILD, OR PHYSIQUE (BODY TYPES: ECTOMORPH, MESOMORPH, ENDOMORPH)

5. VOCABULARY CONT… NEGATIVE FEEDBACK- FEEDBACK CONTROL SYSTEM IN WHICH THE LEVEL OF A VARIABLE IS CHANGED IN THE DIRECTION OPPOSITE TO THAT OF THE INITIAL STIMULUS POSITIVE FEEDBACK- FEEDBACK CONTROL SYSTEM THAT IS STIMULATORY; TENDS TO REINFORCE A CHANGE IN THE INTERNAL ENVIRONMENT HOMEOSTASIS- MAINTENANCE OF RELATIVELY CONSTANT INTERNAL CONDITIONS DESPITE CHANGES IN EITHER THE INTERNAL AND EXTERNAL ENVIRONMENT METABOLISM- STEPS INVOLVED IN THE BREAKDOWN OF NUTRIENT MATERIALS TO PRODUCE ENERGY AND THE TRANSFORMATION OF ONE MATERIAL INTO ANOTHER

6. Movement - self initiated change in position, motion of internal parts Responsiveness (irritability) - Ability to sense changes within, or around the organism and react to them Growth - increase in body size Reproduction - Parents produce offspring / producing new individuals Respiration - Obtaining oxygen (O2), using it to release energy from food substances, and getting rid of wastes

7. Digestion - Chemically changing (breaking down) food substances, and getting rid of wastes Absorption - Passage of Digested products (food substances) through membranes and into body fluids Circulation - Movement of substances throughout the body Assimilation - Changing absorbed substances into chemically different substances Excretion - Removal of wastes

8. I am walking to Mcdonalds (movement) I stop at the traffic light (response) My body is growing (growth) I am breathing air (respiration) I get a hamburger and eat it (digestion) My body absorbs the hamburger (absorption) The hamburger circulates in my body (circulation) The hamburger is changed to things my body needs (assimilation) Eventually, I go to the bathroom (excretion) Someday I may reproduce (reproduction)

9. Metabolism = all the physical and chemical changes Bodily needs = food, oxygen, water, heat Homeostasis = tendency of the body to maintain a stable, balanced, internal environment. “Sameness”

11. Axial Portion - head, neck, trunk Appendicular Portion - arms & legs 1. Several body cavities 2. Layers of membranes within cavities 3. Variety of organs and organ systems within cavities (VISCERA = internal organs. "Visceral organs")

12. BODY CAVITIES DORSAL = BACK SIDE VENTRAL = FRONT SIDE THORACIC = CHEST (HEART, TRACHEA, LUNGS..) ABDOMEN = STOMACH AREA (SPLEEN, INTESTINES) PELVIC = LOWER ABDOMEN (BLADDER, REPRODUCTIVE ORGANS) DIAPHRAGM: SEPARATES THE THORACIC AND PELVIC REGION SEROUS MEMBRANE - COVERS AND SURROUNDS ORGANS SEROUS FLUID - LUBRICATES ORGANS

15. Label the body cavities (use your book) IN-CLASS ASSIGNMENT

16. ABDOMINOPELVIC QUADRANTS

17. ABDOMINOPELVIC REGIONS

18. Serous Membrane - two layered, covers organs o Outer layer = parietal o Inner layer = visceral (lines the organs) Serous fluid – lubricating fluid

19. Pleura = lungs Pericardium = heart Peritoneum = organs (abdominopelvic region)

20. VISCERAL PLEURA / PARIETAL PLEURA VISCERAL PERICARDIUM / PARIETAL PERICARDIUM VISCERAL PERITONEUM / PARIETAL PERITONEUM

21. Organ Systems Concept Map

22. Anatomical Terminology Anatomical Position = standing erect, face forward, arms at side, palms facing forward *Study and learn the following terms* 1. Superior 2. Inferior 3. Anterior 4. Posterior 5. Medial 6. Lateral 7. Proximal 8. Distal 9. Superficial 10. Deep

24. Homework: Fill out the chart on the body regions body regions Body Regions
