Fetal Pig Dissection

Front 1

hard palate

Back 1

the relatively hard, bony anterior portion of that palate; together with the tongue, functions in mechanical digestion of food and formation of vocalization

Front 2

soft palate

Back 2

back of the top of the mouth; closes off nasal passages during swallowing

Front 3

nasopharynx

Back 3

nasal cavity; assists in breathing and temperature/humidity regulation of incoming air

Front 4

esophagus

Back 4

the muscular membranous tube for the passage of food (via peristalsis) from the pharynx to the stomach

Front 5

trachea

Back 5

a thin-walled tube of cartilaginous and membranous tissue descending from the larynx to the bronchi and carrying air to the lungs

Front 6

epiglottis

Back 6

the thin elastic cartilaginous structure located at the root of the tongue that folds over the glottis to prevent food and liquid from entering the trachea during the act of swallowing

Front 7

thoracic cavity

Back 7

cavity above the diaphragm containing heart and lungs

Front 8

abdominal cavity

Back 8

cavity below the diaphragm containing abdominal organs

Front 9

umbilical cord

Back 9

the flexible cordlike structure connecting a fetus at the navel with the lacenta and containing two umbilical arteries and one vinthat transport nourishment to the fetus and remove its wastes

Front 10

scrotal sac

Back 10

the swollen double sac ventral o the anus containing the male gonads

Front 11

Hebrews 13:16

Back 11

And do not forget to do good and to share with others, for with such sacrifices God is pleased.

Hint 11

And do not forget

Front 12

liver

Back 12

a large organ located above/in front of the stomach. t is responsible for most body chemistry
1) filtering toxins from the blood
2) production of bile (break down fats)

Front 13

stomach

Back 13

1) mechanical food digestion
2) chemical food digestion

Front 14

rugae and sphincters

Back 14

the folds of the stomach which aid in mechanical digestion, can stretch as stomach enlarges; the muscles which regulate food into the stomach (cardiac sphincter) and food into the small intestine (pyloric sphincter)

Front 15

spleen

Back 15

large, highly vascular lymphoid organ, lying in the human body to the left of the stomach below the diaphragm
1) store blood
2) disintegrate old blood cells
3) filter foreign substances from the blood

Front 16

small intestine

Back 16

the longest part of the intestine
1) chemical digestion of food
2) subsequent absorption into bloodstream

Front 17

villi

Back 17

thousands of small harlike extensions lining the small intestine which aid in absorption of food in to the bloodstream by increasing the surface area of the small intestine

Front 18

large intestine

Back 18

the final part of the digestive tract
1) re-absorption of water to maintain homeostasis
2) storage of feces

Front 19

rectum

Back 19

the lower part of hte large intestine, where feces are stores before they are excreted

Front 20

aorta

Back 20

the largest artery in the body; orginate in left ventricle,
1) send oxygenated blood throughout the body

Front 21

coronary artery

Back 21

the main artery supplying blood to the heart msucle itself

Front 22

kidneys

Back 22

either one of a pair of organs in the dorsal region of the vertebrate abdominal cavity
1) maintains proper water and electrolyte balance
2) regulates acid-base concentration
3) filters the blood of metabolic wastes, then excreted as urine

Front 23

urinary bladder

Back 23

stores urine

Front 24

right and left atria

Back 24

the anterior thin-walled chambers of the heart which receive blood from the body (right) and the lungs (left) and send it to the ventricles

Front 25

right and left ventricles

Back 25

the posterior, thick-walled chambers of the heart which receive blood from the atria and pump it to the lungs (right) and the body (left)
