Transcript and Presenter's Notes

Title: Fetal%20Pig


1
Fetal Pig
  • A study of mammalian anatomy with emphasis on
    humans and the fetal pig

2
Taxonomy
  • Kingdom Animalia
  • Phylum Chordata (backbone/spine)
  • Class Mammalia
  • Order
  • Genus Sus
  • Species scrofa
  • When naming an animal scientifically you would
    use that animals genus species.
  • Ex. This type of pig is Sus scrofa.

3
Fetal Pig
  • Fetal fetus a stage in animal development. A
    well developed zygote.

4
External/Head Region
  • External structures
  • There are 3 major regions of the pigs body.
    Head, trunk tail.
  • I) Head region usually considered the front or
    top of a species. Usually contains the brain
    most sense organs
  • 1) Eyes (2) sight organs.(3)
  • 2) Jaw a bony area of the head that contains
    the teeth (5)
  • 3) Snout the pigs nose used for smelling
    digging (4)
  • 4) Ear organs used for hearing. May be called
    Pinnae (1 2)

5
External/Trunk Region
  • B) Trunk the midsection of a mammal. It is
    broken into 2 sections, the thorax (upper trunk)
    abdomen (lower trunk).
  • Legs- front hind. Used for movement
  • Umbilicus (umbilical chord) small tube that
    connects the fetus to the mothers uterus. Used
    to feed the baby in the womb.(6)
  • Nipples on males females, but often more on
    the female pig. Used to feed the young milk.
    (10)
  • Reproductive organs For reproducing.
  • a) Male- penis scrotal sac. (May not be
    outwardly visible.) (9)
  • b) Female Vagina
  • Anus pore used for eliminating solid waste from
    the body. (May be considered part of the tail
    region as well.(11)

6
External/Tail
  • Tail the back of some species. A tail can be
    used for anything from swatting pests grasping
    objects to attracting mates distracting
    predators.

7
The Internal Structures
  • All internal structures will be put into body
    systems.
  • The systems will include
  • Digestive/Excretory
  • Urogenital/Reproductive
  • Respiratory
  • Circulatory
  • Nervous
  • Skeletal
  • Muscular
  • Not all systems or organs will be mentioned

8
Digestive/Excretory Systems
  • Digestive/Excretory system converts food to
    energy for the bodys use removes waste from
    the body.
  • Liver organ that removes waste from some foods.
    (detoxification) It also stores bile. Usually
    brown.
  • Diaphragm muscle between abdominal thoracic
    cavities that separates them puts pressure on
    lungs esophagus.
  • Tongue taste organ with 4 taste buds on it. (
    sweet, sour, salty, bitter)
  • Esophagus muscular tube behind the tongue that
    connects mouth to stomach.
  • Stomach stores digests food using enzymes
    stomach acids.
  • Small intestine smaller tube that connects
    stomach to large intestine beginning of waste
    removal (excretory system).
  • Large intestine also called colon. Waste
    removal is its function.
  • Rectum a muscle at the end of the large
    intestine that pushes feces (solid waste from the
    body) out.
  • Anus an external feature but a pore where the
    waste leaves the body.
  • Gall bladder small greenish structure behind
    the liver. It contains bile helps detoxify
    food.
  • Spleen connected to the stomach. It makes white
    blood cells so it is actually part of the
    circulatory system. Long thin.
  • Pancreas in the mesentery (web-like connective
    tissue) behind stomach. Usually it is gray
    bumpy has enzymes that aid in digestion.

9
Urogenital Reproductive Systems
  • Urogenital Reproductive systems to remove
    liquid waste reproduce offspring
  • Urogenital
  • Kidney bean shaped organ on the wall of the
    back that removes excess salt, H2O, urea
    (nitrogen waste) from the blood.
  • Ureter small tubes that empty the kidneys to
    the bladder.
  • Bladder the bulb-like sac organ that stores
    urine until it is ready to be removed.
  • Urethra a tube that empties urine from the
    bladder out of body.
  • Male reproductive system
  • Penis- male reproductive organ
  • Scrotum sac that protects the testes.
  • Testes 2 male oval organs that produce sperm.
  • Female reproductive system
  • Vagina female reproductive organ.
  • Ovaries 2 small round organs attached to the
    back produce egg cells.
  • Oviduct (Fallopian tube) 2 tubes that connect
    ovaries to the Uterus for fertilization. Pig has
    Uterine horns (extensions that help mammals with
    multiple births).
  • Uterus a sac where fertilization takes place
    the fetus is nurtured.

11
Respiratory System
  • Respiratory system brings in oxygen removes
    carbon dioxide.
  • Mouth- where air enters. Tongue teeth are in
    the mouth.
  • Pharynx a cavity that has the organs for
    breathing.
  • Larynx voicebox
  • Trachea windpipe. Ringed cartilage.
  • Lungs 2 organs that exchange gases.

12
Circulatory System
  • Circulatory system - transports, blood, oxygen,
    nutrients to the body.
  • Blood vessels carry blood
  • Veins smaller blood vessels bring blood back to
    the heart from the body. This blood contains
    little or no oxygen.
  • Arteries- larger blood vessels that carry blood
    with oxygen from the heart to the body.
  • Capillaries small connecting blood vessels.
  • Heart- muscular organ that pumps blood to the
    body.

13
Nervous System
  • Nervous System controls bodys senses
    functions, actions.
  • Brain the organ that controls all the bodys
    functions, the nerve center.
  • Spinal Chord nervous tissue behind the
    backbone. Like an electrical wire to the rest of
    the body. Sends signals from brain to bodys
    nerves.

14
Skeletal System
  • Skeletal system Protection, movement,
    support.
  • All bones (humans 206) cartilages (soft bone)
    are part of this system

15
Muscular System
  • Muscular system for movement insulation.
  • It includes all ligaments (muscle to bone)
    tendons (muscle to muscle) (connective tissues).
