• 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)

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

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?

Coordination, Regulation, and Defense

• Nervous System
• Brain and spinal chord and nerves outside brain
  and spinal chord and sense organs (eye, ear)
• Communication

(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

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

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

Reproduction

• Male
• testes, seminal vesicles, urethra, penis
• Produce and deliver sperm
• Female
• ovaries, fallopian tubes, uterus, vagina
• Produce eggs, house developing embryo
