Fetal Pig Physiology Flashcards
Site of absorption of nutrients into the bloodstream; also plays a major role in breaking down food
small intestine
Front teeth; bite into food
incisors
Directional term that means to the side
lateral
Chemically digests food with gastric fluid; mechanically digests food by churning
stomach
Narrow tube that carries urine from the bladder and out of the body
urethra
Body cavity that includes the intestines, stomach, spleen, gallbladder, and more!
abdominal cavity
Epithelial tissue membrane in the abdominal and thoracic cavities that holds the organs in place and secretes a lubricating fluid so that the organs can move without friction
mesentery
Pigs have more than humans! Approximately 19,000 in pigs and only 9,000 in humans. Found all over the tongue.
taste buds
Sharp teeth; grip and tear food
canines
Creates enzymes that aid digestion and are passed into the small intestine
pancreas
Sweat glands; not enough present in a pig to adequately cool the body
sudoriferous glands
Flap above the glottis/trachea that covers the airway while swallowing food/water
epiglottis
Chamber of the heart that pumps deoxygenated blood to the lungs
right ventricle
Line the small intestine, increasing its surface area so that more absorption can occur
villi
Projection of the right atrium that increases its capacity
right auricle
Two tubes that the trachea splits into; the right one goes to the right lung and the left one goes to the left lung
bronchi
Found posterior to the umbilical cord in male pigs; found near the anus in female pigs
urogenital opening
Endocrine gland that shrinks rapidly as you age
thymus
Strong cartilage tube that passes air to and from the lungs
trachea
Endocrine gland that creates hormones that regulate metabolism
thyroid gland
Directional term that means in front (towards the head of the pig)
anterior
Creates insulin and glucagon to regulate blood sugar
pancreas
Behind the hard palate; has only muscle and soft tissue behind it
soft palate
Breaks down toxins in our blood and produces bile (which helps to break down fats)
liver
Breaks down toxins in our blood and produces bile (which helps to break down fats)
liver
Ears of the fetal pig
pinnae
Folds inside the stomach that increase the surface area, allowing it to stretch
rugae
Stores feces until defecation, where it passes it through the anus
rectum
The part of the hair embedded and anchored in the follicle (skin)
hair root
Meshy substance that attaches the abdominal organs to the dorsal wall of the abdomen
peritoneum
Sac that contains the testes
scrotum
Remove clean blood from the kidneys
renal vein
Collects urine inside each kidney and dumps it into the ureter
renal pelvis
Body cavity that includes the brain
cranial cavity
Blood vessel that supplies oxygenated blood to the heart muscle
coronary artery
Directional term that means behind
posterior
Chamber of the heart that receives freshly oxygenated blood from the lungs
left atrium
Membrane around the heart that is filled with fluid to reduce friction as the heart beats
pericardium
Gland found above each kidney
adrenal gland
Tiny tubes that branch through each lung
bronchioles
Site of breathing; divided into lobes
lungs
Millions of tiny air sacs inside each lung; where gases pass between the lungs and bloodstream
alveoli
Muscular tube that pushes food from the mouth to the stomach
esophagus
Muscular pump that forces blood through the veins and arteries
heart
Body cavity that includes the heart, lungs, trachea, thymus, and thyroid gland
thoracic cavity
Contracts to cause inhalation; relaxes to cause exhalation
diaphragm
Inner layer of the kidney
renal medulla
Round muscle that controls when food empties from the stomach to the small intestine
pyloric sphincter
Nipples; present in both male and female pigs
teats
Also known as the colon
large intestine
Deliver blood between the mother pig and fetus, providing the fetus with oxygen and nutrients
umbilical arteries and veins
Stores bile and passes it to the small intestine
gallbladder
Narrow tubes that carry urine from the kidneys to the urinary bladder
ureters
Directional term that means along the back
dorsal
Has 4 distinct chambers
heart
Passes oxygenated blood from the left ventricle to the body
aorta
The visible part of the hair that sticks out from the skin
hair shaft
Stores urine until urination can occur
urinary bladder
Creates hormones that fuel the production and maturation of T cells
thymus gland
Directional term that means toward the midline (ex. Umbilical cord)
medial
Chamber of the heart that receives deoxygenated blood from the body; passes it to the right ventricle
right atrium
Produce adrenaline, cortisol, and other hormones
adrenal glands
Removes old, damaged red blood cells from the bloodstream
spleen
Endocrine gland that trains and matures T cells
thymus gland
Muscular sheet that separates the abdominal and thoracic cavities
diaphragm
Tunnel shaped structure in the epidermis that the hair grows from
hair follicle
Also known as the voice box; holds the vocal cords
larynx
Tissue that connects muscles to bones
tendon
Smooth muscle pouch that comes after the esophagus in the GI tract
stomach
Passes deoxygenated blood from the right ventricle to the lungs
pulmonary artery
Projection of the left atrium that increases its capacity
left auricle
Opening to the outside world from the urinary and reproductive systems
urogenital opening
Filter blood by removing waste and excess water, creating urine
kidneys
The hard part on the roof of the mouth; has bone behind it
hard palate
Organ near the stomach that is part of the immune system
spleen
Outer layer of the kidney
renal cortex
Contract and relax to cause movement throughout the body
muscles
Deliver blood that needs to be cleaned to the kidneys
renal arteries
Back teeth; grind up food
molars
Part of both the digestive and endocrine system
pancreas
One end attached to the fetal pig, the other end attached to the placenta
umbilical cord
The largest organ in the abdominal cavity
liver
Comes after the small intestine in the gastrointestinal tract
large intestine
Directional term that means along the belly
ventral
Produces additional white blood cells during an infection
spleen
Full of healthy bacteria that aid digestion; absorbs water from digested food
large intestine
Chamber of the heart that pumps freshly oxygenated blood to the body
left ventricle
