Title: Anatomy and Physiology Lecture 7


1
Anatomy and PhysiologyLecture 7
  • MACC BIOLOGY 101
  • Bill Palmer

2
Anatomy
  • Study of the bodys structure and the
    relationships between the bodys parts

3
Physiology
  • The study of how the parts work

4
Main Cavities of Human body
5
Organization
6
Tissues
  1. Epithelial covers surfaces (e.g. skin, lining
    of blood vessels, lungs and stomach

7
Tissues
  • 2. Connective stabilizes and supports other
    tissue (e.g. bone, cartilage, blood, fat)

8
Tissues
  • 3. Muscle has ability to contract or shorten
    (e.g. stomach, heart, bicep)

9
Tissues
  • 4. Nervous specialized for rapid conduction of
    messages (e.g. neurons)

11
Organs
  • Organs are composed of numerous tissues

12
Organ Systems
  • Body Support and Movement
  • Integument (skin)
  • Skeletal
  • Muscular
  • Coordination, Regulation and Defense
  • Nervous
  • Endocrine
  • Lymphatic

13
Organ Systems
  • 3. Transport and Exchange with environment
  • Cardiovascular
  • Respiratory
  • Digestive
  • Urinary
  • Reproductive

14
Support and Movement
  • Integument System
  • Skin, hair, nails, glands
  • Protects, regulates temperature

15
(No Transcript)
16
Support and Movement
  • Skeletal System
  • 206 bones, cartilages, ligaments
  • Strengthens, protects, stores of minerals
  • Weird Fact The human baby has 305 bones and the
    adult has 206 bones! What happened?

19
Support and Movement
  • Muscle System
  • 700 skeletal muscles
  • posture, balance, supports, generates heat,
    movement

20
(No Transcript)
21
Coordination, Regulation, and Defense
  • Nervous System
  • Brain and spinal chord and nerves outside brain
    and spinal chord and sense organs (eye, ear)
  • Communication

22
(No Transcript)
23
Coordination, Regulation, and Defense
  • Endocrine System
  • Uses hormones to send signals to the body
  • Glands (pituitary, thyroid, parathyroid, thymus,
    pancreas, gonad)

24
(No Transcript)
25
Coordination, Regulation, and Defense
  • Lymphatic System
  • Lymphatic vessels, lymph nodes, thymus, tonsils,
    spleen
  • Immune functions

26
(No Transcript)
27
Transport and Exchange with the Environment
  • Cardiovascular System
  • Heart, blood, blood vessels, marrow of bone
    (where red blood cells are made
  • Carries nutrients, dissolved gases, and hormones
    to tissues and carries waste product from tissue

28
(No Transcript)
29
Transport and Exchange with the Environment
  • Respiratory System
  • Lungs and passageways that carry air to and from
    lungs
  • Oxygen comes into system and carbon dioxides is
    expelled

30
(No Transcript)
31
Transport and Exchange with the Environment
  • Digestive System
  • Digestive tract (begins at mouth and ends at
    anus) with stomach, small/large intestines,
    pancreas, liver, etc.
  • Absorb nutrients and expel wastes

32
(No Transcript)
33
Transport and Exchange with the Environment
  • Urinary System
  • Kidney, ureter, bladder, urethra
  • Absorb/retain water, proteins and expel wastes

34
(No Transcript)
35
Reproduction
  • Male
  • testes, seminal vesicles, urethra, penis
  • Produce and deliver sperm
  • Female
  • ovaries, fallopian tubes, uterus, vagina
  • Produce eggs, house developing embryo

36

37
Wrap up
  • 1. What is anatomy?
  • 2. What is physiology?
  • 3. What are the 6 main cavities of the body?
  • 4. How is the body organized?
  • 5. What are the 4 types of tissues? Examples?

38
Wrap up
  • 6. What are the 3 classification systems of the
    organ systems?
  • 7. What are the 11 organ systems?
  • 8. Parts of the organ systems?
  • 9. Purposes of the organs/organ systems?
  • 10. Recognize, give examples, functions, etc.
