Transcript

  • 1. Chapter 1 Introduction PowerPoint Presentation to accompany Hole’s Human Anatomy and Physiology, 10 th edition , edited by S.C. Wache for Biol2064.01
  • 2.   You are responsible for the following figures and tables : Fig. 1.1 - Posterior view of biped human. Fig. 1.3, Tab. 1.1 - Levels of Organization. Tab. 1.2 - Organ Systems. Tab. 1.3 - Characteristics of living matter versus dead matter. Tab. 1.4 - Requirements of living organisms. The human body is organized in cavities. Fig. 1.9 - Body cavities. Fig. 1.10 - Head cavities. Study the serous membranes that enclose important organs. Fig. 1.11, 1.12 Read TB p. 21 on "anatomical terminology". Study 'body sections'. Fig. 1.21 - coronal v. sagittal v. transverse cuts. Fig. 1.23 - Subdivisions of the abdominal cavity. Fig. 1.24 - learn by heart as many of these terms as possible.
  • 3. Understanding the Human Body Our earliest ancestors were interested in the way their bodies worked. posterior view of biped human showing the muscles.
  • 4. Anatomy and Physiology
    • Anatomy involves the study of the structures of the body parts (morphology).
    • Physiology considers the function of these body parts, what they do and how they do it.
    • Both anatomy and physiology rely on each other. Form follows function and function leads to form.
  • 5. Characteristics of Living Organisms Unlike Non-Living Matter
    • Movement
    • Responsiveness
    • Growth
    • Reproduction
    • Respiration
    • Digestion
    • Absorption
    • Circulation
    • Assimilation
    • Excretion
  • 6. Requirements of Life (or: Parameters We Are Dependent Upon, THAT IS, When They Change , Our Body Responds)
    • Water - required for metabolism, transport, regulation
    • Food - substances that provide nutrients
    • Oxygen - used in the release of energy
    • Heat - a form of energy which helps control metabolic reactions
    • Pressure - application of force on an object
  • 7.  
  • 8. Homeostasis
    • The body’s maintenance of a stable internal environment is called homeostasis.
    • Homeostasis is often maintained by a mechanism called negative feedback.
    • The internal environment of the body protects cells
  • 9. Negative feedback
    • Homeostasis is the consequence of a self-regulating control system that operates by a mechanism called negative feedback.
    • Such a system receives signals about changes in the internal environment and then causes responses that reverse these changes back to the set point.
  • 10. Fig. 1.8 (also Fig. 1.6)
  • 11. Question
    • How is the Human body organized ?
    Answer
    • A. We begin with the smallest building block of the human body all the way to organ systems of the body.
    • B. We study body cavities and body regions.
  • 12. Organization of the Human Body
    • Atoms- tiny particles that make up matter or elements
    • Molecules- atoms bound together
    • Macromolecules- large molecules, polymers
    • Organelles- activity specific structures
    • Fig. 1.3
  • 13.
    • Cells - basic unit of structure and function
    • Tissues - groups of cells
    • Organs - structures with specialized function
    • Organ systems - groups of organs that perform a function
    • Organism - the sum of the organ systems
    Organization continued….

  • 15. Organ Systems
    • Integumentary
    • Skeletal
    • Muscular
    • Nervous
    • Endocrine
    • Cardiovascular
    • Lymphatic
    • Digestive
    • Respiratory
    • Urinary
    • Reproductive

  • 26. Serous Membranes
    • Parietal layer lines the wall.
    • Visceral layer lines the organs.
    • Serous fluid is found in the cavity between these two membranes that make up a serous membrane.
    • see also textbook Figs. 1.11 and 1.12
  • 27. Serous Membranes

    • Anterior/Posterior : in front of or behind
    • Medial/Lateral : towards the middle or side
    • Proximal : close to a body part
    • Distal : far from a body part
    • Superficial/Deep : on the surface or lying beneath
