1 Introduction to Anatomy & Physiology

2 Standard IHS 7 Introduction to Life Changes – The Process of Change
HS-IHS-7: The student will compare and contrast the life changes from conception throughout the lifespan as it relates to all growth and developmental needs. Investigate the interdependence of the various body systems to each other and to the body as a whole. Explain the role of homeostasis and its mechanisms as these relate to the body as a whole and predict the consequences of the failure to maintain homeostasis. Describe how structure and function are related in terms of cell and tissue types. Describe the stages of growth and development from conception throughout the lifespan including correlations to Maslow’s Hierarchy of Needs. Examine various conditions that change normal body functions – i.e. tissue rejection, allergies, injury, diseases and disorders - and how the body responds. Describe effects of aging on all body systems.

3 OBJECTIVE INVESTIGATE THE INTERDEPENDENCE OF BODY SYSTEMS TO EACH OTHER & TO THE BODY AS A WHOLE

4 How Well Mastery on all assessments, Completion of all Labs
Completion of worksheet packets for all units

5 ANATOMY THE STUDY OF THE FORM & STRUCTURE OF THE HUMAN BODY
Where is the heart? How large is the liver? How many muscles do you have?

6 Study of how a living organism works.
PHYSIOLOGY Study of how a living organism works. How does the heart know when to beat? What makes a muscle stretch? How does the liver store CHO?

7 PROTOPLASM Basic substance of all LIFE ordinary elements such as C O2

8 CELLS Protoplasm comes together to form cells
CELLS are the basic unit of structure & function of all living things. Microscopic Carry on all functions of life

9 Require O2 Produce heat & energy Move & adapt to environment Eliminate waste products Perform special functions

10 CELL PARTS Cell membrane- outer protective covering: Allows substances to enter & leave cell Cytoplasm: semi- fluid substance inside of cell. Contains water, fats, proteins, CHO, minerals, salts.

11 ORGANELLS- Structures inside the cell
Nucleus- The brain, main controls Nucleolus- RNA production inside the nucleus Chromatin- Inside the nucleus, makes DNA & chromosomes Mitochondria- rod shaped, powerhouse of the cell, makes energy Golgi Apparatus- Produces, stores & packages secretions for discharge form the cell. Garbage Compactor of the cell

12 Endoplasmic Recticulum- tubular structures that allows for transportation of materials into & out of the cell. Train of the cell smooth- makes cholesterol, detox from drugs Rough- builds proteins Lysosomes- oval bodies that digest & destroy old cells. Pac Man of the cell Pinocytic Vesicles- folds in cell membrane. The folds capture & hold protein & fats, then form bubbles to help then enter the cell

13 Reproduction Cells need to reproduce to keep organism alive
Skin, blood forming cells, & intestinal tract cells reproduce continuously Muscle cells reproduce every few years, but most can be enlarged by exercising Special cells such as nerve cells in the brain & spinal cord do not reproduce after birth, & if they are damaged they cannot be repaired or replaced

14 MITOSIS VS MEIOSIS Mitosis is the process of cell division of a normal cell. Has 46 chromosomes Meiosis is the cell division of a sex cell (sperm & ovum) which halves the number of chromosomes. Each sex cell has 23 chromosomes.

15 Tissues Cells of the same type that are joined together for a common purpose

16 4 TYPES OF TISSUE EPITHELIAL CONNECTIVE NERVE MUSCLE

17 EPITHELIAL COVERS THE BODY , MAIN TISSUE OF THE SKIN
FORMS LINING OF THE INTESTINAL, RESPIRATORY, CIRCULATORY & URINARY TRACT FORMS GLANDS OF THE BODY

18 CONNECTIVE SUPPORTIVE FABRIC OF THE BODY 3 TYPES
SOFT- Adipose or fat (insulates body) Tendons, ligaments HARD- Cartilage & bone LIQUID- Blood

19

20 NERVE Made of neurons Carries nerve messages from brain throughout the body

21 MUSCLE Produces power & movement of the body 3 Types
Skeletal- attaches to bone to move body Cardiac- cause heart to beat Smooth present in the walls of blood vessels, walls of respiratory, urinary & digestive tracks

22 Organs TISSUES JOINED TOGETHER TO PERFORM A COMMON FUNCTION
Heart, lungs, stomach, brain, skin, pancreas, uterus etc

23 SYSTEM Organs joined together for a common purpose Digestive System
Respiratory System Urinary System Reproductive System

24 Organism Systems joined together for a common good THE HUMAN ORGANISM
