Transcription

1 PowerPoint Lecture Slide Presentation by Patty Bostwick-Taylor, Florence-Darlington Technical College The Human Body: An Orientation 1PART A

2 The Human Body An Orientation Anatomy Study of the structure and shape of the body and its parts Physiology Study of how the body and its parts work or function

3 Anatomy Levels of Study Gross anatomy Large structures Easily observable Figure 14.1

4 Anatomy Levels of Study Microscopic Anatomy Very small structures Can only be viewed with a microscope Figure 14.4c d

5 Levels of Structural Organization cell Cellular level Cells are made up of molecules Molecules Atoms Chemical level Atoms combine to form molecules Tissue level Tissues consist of similar types of cells Epithelial Connective Organ level Organs are made up of different types of s Blood vessel (organ) Cardiovascular system Organ system level Organ systems consist of different organs that work together closely Organismal level Human organisms are made up of many organ systems Figure 1.1

6 Levels of Structural Organization Molecules Atoms Chemical level Atoms combine to form molecules Figure 1.1, step 1

7 Levels of Structural Organization cell Cellular level Cells are made up of molecules Molecules Atoms Chemical level Atoms combine to form molecules Figure 1.1, step 2

8 Levels of Structural Organization cell Cellular level Cells are made up of molecules Molecules Atoms Chemical level Atoms combine to form molecules Tissue level Tissues consist of similar types of cells Figure 1.1, step 3

9 Levels of Structural Organization cell Cellular level Cells are made up of molecules Molecules Atoms Chemical level Atoms combine to form molecules Tissue level Tissues consist of similar types of cells Epithelial Connective Blood vessel (organ) Organ level Organs are made up of different types of s Figure 1.1, step 4

10 Levels of Structural Organization cell Cellular level Cells are made up of molecules Molecules Atoms Chemical level Atoms combine to form molecules Tissue level Tissues consist of similar types of cells Epithelial Connective Organ level Organs are made up of different types of s Blood vessel (organ) Cardiovascular system Organ system level Organ systems consist of different organs that work together closely Figure 1.1, step 5

11 Levels of Structural Organization cell Cellular level Cells are made up of molecules Molecules Atoms Chemical level Atoms combine to form molecules Tissue level Tissues consist of similar types of cells Epithelial Connective Organ level Organs are made up of different types of s Blood vessel (organ) Cardiovascular system Organ system level Organ systems consist of different organs that work together closely Organismal level Human organisms are made up of many organ systems Figure 1.1, step 6

12 Organ System Overview Integumentary Forms the external body covering Protects deeper from injury Helps regulate body temperature Location of cutaneous nerve receptors Figure 1.2a

13 Organ System Overview Skeletal Protects and supports body organs Provides attachment for movement Site of blood cell formation Stores minerals Figure 1.2b

14 Organ System Overview Muscular Produces movement Maintains posture Produces heat Figure 1.2c

15 Organ System Overview Nervous Fast-acting control system Responds to internal and external change Activates s and glands Figure 1.2d

16 Organ System Overview Endocrine Secretes regulatory hormones Growth Reproduction Metabolism Figure 1.2e
