Title: Organization


1
Organization Body Systems
  • Unit 1 Intro to Anatomy
  • Chapter 1.1

2
Anatomy Physiology
  • The study of the human body
  • Anatomy is concerned with the structure of a part

3
  • Physiology is concerned with the function of the
    part

4
Levels of Organization
  • Body is organized into levels from most simple to
    most complex

5
Atoms
  • Most simple
  • Compose all substances
  • Chemicals elements

6
Molecules
  • Atoms joined together form molecules
  • Example amino acids

7
Macromolecules
  • Molecules joined together form macromolecules
  • Example protein

8
Organelles
  • Tiny structures found in cells that perform
    cellular functions
  • Example mitochondria supplies cell with energy

9
Cells
  • Macromolecules found in all cells
  • Basic unit of all living things

10
Tissue
  • Composed of similar types of cells and performs a
    specific function
  • Example blood, muscle, fat

11
Organs
  • Groups of tissues working together to perform a
    specific function
  • Example heart, stomach

12
Organ System
  • Groups of organs that perform a particular
    function
  • Example digestive system supply body with the
    nutrients needed for growth and repair

13
Organism
  • All the body systems make up an organism
  • Unicellular organism made up of one cell
  • Example amoeba
  • Multicellular organism made up of many cells
  • Example gorillas

14
Review
  • ________ is concerned with the structure or an
    organ or part, while ________ is concerned with
    the function.
  • ANSWER Anatomy, Physiology

15
  • ___________ are groups of tissues working
    together to perform a specific function.
  • Answer Organs

16
  • 3. ______________ organisms are made up of many
    cells, while ___________ organisms are made up of
    one cell.
  • ANSWER multicellular, unicellular

17
  • 4. Basic unit of all living things are called
    ________.
  • ANSWER cells

18
Homeostasis
  • Homeostasis is the relative constancy of the
    bodys internal environment
  • Even when external conditions change, the bodys
    internal condition stays within a narrow range
  • All systems of the body contribute toward
    maintaining homeostasis
  • If the bodys internal conditions changes
    greatly, illness results

19
(No Transcript)
20
  • 2 types of homeostasis mechanisms
  • Negative feedback returns a variable back to a
    the set point

21
  • Positive feedback mechanism that brings about
    an ever greater change in the same direction
  • Example Childbirth

23
Introduction
  • Organs in the body work together in systems
  • 11 organ systems in the body
  • Organ systems can be divided into 4 categories
    based on function

24
(No Transcript)
25
Support, Movement, Protection
  • Integumentary System
  • Organs skin and accessory organs (hair nails)
  • Function protects tissue, regulate body
    temperature contains sense organs

26
  • Skeletal System
  • Organs bones, cartilage, ligaments
  • Function protects body parts, produce blood
    cells, stores calcium phosphorus salts

27
  • Muscular System
  • Organs skeletal, cardiac, and smooth muscles
  • Function move voluntarily, respond to stimuli,
    produce body heat

28
Integration Coordination
  • Nervous System
  • Organs brain, spinal cord nerves
  • Function conducts nerve impulses from the sense
    organs to the brain and then to the muscles and
    gland

29
  • Endocrine System
  • Organs Hypothalamus, pituitary, thyroid,
    parathyroid, adrenals, pancreas, ovaries, testes
  • Function secretes chemicals that are messengers
    between body part, maintain proper functioning of
    reproductive system

30
Maintenance of Body
  • Circulatory (Cardiovascular) system
  • Organs Heart, blood vessels, blood
  • Function transports nutrients and oxygen to
    cells through blood, removes wastes

31
  • Immune (Lymphatic) System
  • Organs Lymph nodes, thymus, spleen
  • Function protects body from disease

32
  • Respiratory System
  • Organs Nose, pharynx, larynx, trachea, lungs
  • Function bring oxygen into lungs and take carbon
    dioxide out of the lungs

33
  • Digestive System
  • Organs mouth, pharynx, esophagus, stomach, small
    large intestine, rectum
  • Function receive food and digest into nutrient
    molecules

34
  • Urinary System
  • Organs kidneys and urinary bladder
  • Function gets rid of nitrogenous wastes, helps
    regulate fluid level and chemical content of the
    blood

35
Reproduction Development
  • Reproductive System
  • Organs Male testes, epididymis, vas
    deferens, urethra, penis Female ovaries,
    Fallopian tubes, vagina, uterus
  • Function produce sex cells, nourish and protect
    fetus (female)
