102 abuldinov-human physiology

  1. 1. Human Physiology Introduction to the field of human physiology
  2. 2. Introduction <ul><li>Living systems possess a special organization </li></ul><ul><li>Physiology studies two related aspects of that organization: structure and function </li></ul><ul><li>For this reason physiology is closely related to Anatomy and Biochemistry </li></ul>
  3. 3. Homeostasis <ul><li>This is the name for the processes which keep the condition and environment of the tissues in the proper condition to sustain life. </li></ul>
  4. 4. Cells <ul><li>Cells are the basic units of life </li></ul><ul><li>they make up tissues and organs in the body </li></ul><ul><li>Cells can only come from other cells (The CELL THEORY) </li></ul>
  5. 5. Tissues <ul><li>muscular </li></ul><ul><li>nervous </li></ul><ul><li>epithelial </li></ul><ul><li>connective </li></ul>
  6. 6. Glands <ul><li>Epithelial tissue </li></ul><ul><li>Specialized for secretion </li></ul><ul><li>Exocrine glands: secrete through ducts to the outside of the body </li></ul><ul><li>Endocrine glands: ductless glands which produce hormones which are released into the blood </li></ul>
  7. 7. Organs <ul><li>Two or more types of primary tissue </li></ul><ul><li>Organized to perform a particular function </li></ul>
  8. 8. Examples of Organs <ul><li>Stomach </li></ul><ul><li>Heart </li></ul><ul><li>Liver </li></ul><ul><li>Kidney </li></ul><ul><li>Brain </li></ul><ul><li>etc </li></ul>
  9. 9. Homeostasis: The Essence of Life <ul><li>Cells live in a fairly constant environment </li></ul><ul><li>The cells, in turn, constitute the tissues which provide that environment </li></ul>Body systems Homeostasis Cells
  10. 10. Body Systems <ul><li>Nervous </li></ul><ul><li>Endocrine </li></ul><ul><li>Immune </li></ul><ul><li>Circulatory </li></ul><ul><li>Muscle/skeletal </li></ul><ul><li>Integument </li></ul><ul><li>Respiratory </li></ul><ul><li>Urinary </li></ul><ul><li>Digestive </li></ul><ul><li>Reproductive </li></ul>
  11. 11. Failure of Homeostasis <ul><li>Often leads to sickness and eventually death </li></ul>
  12. 12. Thanks for Attention!
