Lab 1 - Internal Anatomy of a Pig Flashcards
How many Salivary Glands foes pigs and most mammals have?
Three
Where is the Parotid Salivary Glands?
below the ears
Where are the Submaxillary Salivary Glands located?
base of the jaw, on medial edge
Where are the Sublingual Salivary Glands located?
either side, below the tounge
What does saliva contain?
Water
Mucin
Bicarbonate
Salivary amylase
Lingual lipase
What is Mucin?
a slippery glycoprotein that functions in lubrication
What is salivary amylase?
Digestive enzyme that breaks down starches into maltose
What is secretory immunoglobulin A (S-Ig-A)
Form of Immunoglobulin A secreted in saliva
What are electrolytes?
sodium, potassium, chloride, and bicarbonate that keep the mouth pH near neutrality
What is Lingual Lipase
enzyme secreted by sublingual salivary gland that works with gastric lipase to start digesting triglycerides.
What is a lysozyme?
antibacterial enzyme
What is the Buccal Cavity?
space between teeth and cheeks
What is the Hard Palate?
roof of the mouth
What is the soft palate?
soft tissue posterior to the hard palate
What is the pharynx?
back of throat, common passageway for food and air
What is the Larynx?
the hollow muscular organ forming an air passage to the lungs and holding the vocal cords in humans and other mammals; the voice box.
What is the epiglottis?
a flap that flips down to cover the entry to the trachea during swallowing
What is the thyroid cartilage?
Protects the front of the larynx and forms the Adam’s apple
What is the trachea?
transports air from the larynx to the bronchi
What is the esophagus?
Narrow tube leading from the pharynx to the stomach
what is the pleura?
Sacs that surround the lungs
What are the lungs?
paired organs in the thoracic cavity dorsal to the heart
What is the heart?
located caudally to larynx and ventrally to the lungs
What is the pericardium?
the membrane enclosing the heart
What is the diaphragm?
The muscle at the bottom of the thoracic cavity
what is the peritoneum?
the mucus membrane covering the abdominal cavity
What is the liver?
organ lying posterior to the diaphram functions as a metabolic processing unit
maintains levels of nutrients in blood
functions in secretion of bile
What is the Gall bladder?
stores and excretes bile
under right lobe of liver
What is the stomach?
produces HCL and pepsinogen to digest proteins
What is the greater omentum?
part of peritoneum, covers stomach
leukocyte production
What is the spleen?
lateral to stomach
largest lymphatic organ
removes old and damaged erythrocytes
What is the Pancreas?
found in the duodenal loop
has both endocrine and exocrine functions
Endocrine: secretes insulin and glycoprotein
Exocrine: secretes digestive enzymes and proenzymes trypsinogen and chymotrypsinogen
What is the small intestine?
duodenum, jejunum, ileum
digestion of foodstuffs and absorption
What is the duodenum?
first part of small intestine
receives chyme from stomach
produces bicarbonate to neutralize acidic chyme
receives bile from gall bladder
enzymes secreted from pancreas
What is the jejunum?
middle part of small intestine
absorption of amino acids, monosaccharides, calcium and iron
what is the Ileum?
absorption of bile salts, water, electrolytes, and Vit B12
last part of small intestine, connects to large intestine
What is the Mesentery?
Fold of the peritoneum
connect and anchor small intestine
what is the Hepatic Portal System?
blood vessels that collects blood from the stomach, small intestine and large intestine
delivers high nutrient blood to liver
blood vessels are seen in mesentary
What is the Large intestine?
cecum, colon, rectum
What is the Cecum?
blind sac
microbial fermentation of starch and some cellulose
absorption of fermented products and water
What is the Colon?
Longest part of large intestine
microbial fermentation of starch and some cellulose
absorption of fermented products and water
What is the Rectum?
last part of large intestine
formation of feces occurs here
What is the Anus
external opening of digestive track
What are the kidneys?
2 organs lateral to the spine and dorsal to intestines
removal of waste products from blood
regulation of blood volume and body pH
What is the Urinary Bladder?
Stores Urine
Dorsal
back or upper side
Ventral
underside or abdominal area
Anterior
front/frontal
Posterior
back/rear
Medial
toward middle or body midline
Lateral
away from the body midline (side)
Proximal
near, closer to point under consideration
Distal
far or away from point under consideration
Frontal/Coronal
divides animal into dorsal and ventral planes
Transverse/Axial
divides animal into cranial and caudal planes
Median/Midsagittal
separates animal into right or left half
Sagittal
any plane parallel to midsagittal plane
