Fetal Pig

Opening of rectum, undigest food particles excreted.

Sensory/motor nerve originates from Medulla Oblongata and innervates the facial and digastric muscles, taste buds, and salivary glands.

Secrete milk to nourish young.

Bony plate separating rostral portion of oral cavity from the nasopharynx in mammals.

Small canal leading from the parotid gland to oral cavity through which the parotid gland releases salivary enzymes into mouth.

Rather large salivary gland located near the ear of pig.

Enlarged oval-shaped region cranial to the trachea that contains the vocal chords.

Cartilaginous tube extending from larynx to lungs, air is transported through this.

Muscular passageway connecting mouth/oral cavity to stomach.

Endocrine gland, produces Thymosin. Located near Larynx.

oval-shaped endocrine gland located on ventral surface of trachea. Produces thyroxine and calcitonin.

Pumps blood throughout vessels.

Muscular sheet used to ventilate the lungs of mammals.

Large multi-lobed organ. Secretes bile, filters toxins and nutrients from the blood and stores sugars.

Located underside of Liver. Stores bile and releases it into duodenum.

Digestive resorvoir for food. Stores food, chemicals secreted from walls which break down food and prepare them for absorption in intenstines.

Connective membrane that suspends body of organs in the abdominal cavity and holds them together.

Thin tissue surrounding and protecting the heart.

Large muscular chamber of heart, pumps blood out of heart into artery.

One of several small arteries that supply heart with freshly oxygenated blood.

• Cranial: Major vein returning deoxygenated blood from the upper extremities of the body to the right atrium of the heart.
• Caudal: Major vein returning deoxygenated blood from the lower extremities of the body to the right atrium of the heart.

flap-like outer region covering the cranial portion of the atrium.

Chamber of the heart that receives blood.

• Artery: short blood vessels which [in adult] carry deoxygenated blood from the R ventricle of the heart to the lungs
• Veins: blood vessels which [in adult] carry oxygenated blood from lungs to the left atrium of heart.

Large artery arising from the left ventricle that distributes blood the the regions of the body.

Short connection joining pulmonary trunk with the aorta and allowing a portion of the blood from trunk to enter the aorta instead of flowing to the lungs, found only in fetus.

Endocrine gland located medial to the kidney, produces hormones which mediate responses to stressful situations and control blood pressure and carbohydrate and protein metabolism.

Excretory unit, filters blood creating highly concentrated metabolic by-product (urine) which is sent to urinary bladder. Also maintains homeostatic balance of salts, fluid, and ions within the body.

Tube that transports urine from kidney to the urinary bladder for storage.

Tube that leads from the urinary bladder to the outside of the body, transports urine and semen.

Membranous sac that stores excreted urine from kidneys.

Accessory glands of the male reproductive system located at base of penis and urethra that produce alkaline secretions that assist in lubrication during intercourse and neutralize acidity of vagina.

Highly coiled tubule system that cups around the testis and serves as storage and transportation canal for mature sperm.

External reproductive organ of male, deposits semen in reproductive tract of female and carries excretory wastes in form of urine out of body.

Accesory glands of male system located near the junction of urthra and base of penis; in pigs they secret alkaline fluids that neutralize acidity of vagina and nutrients to promote sperm motility and hormones to stimulate uterine contractions.

Pouch extending from the caudal region of male, contains 2 testes. Their presence helps testes to be slightly lower in temperature than rest of abdominal cavity.

Attachment between maternal placenta and fetus which gasses, nutrients, and nitrogenous wastes are transported.

Opening of urethra (in males) or the urogenital sinus (in females) through which urine passes and is eliminated from the body.

Cartilaginous region of roof of mouth that separates oral cavity from the nasal passageway, located towards back of mouth.

Salivary gland located underneath the skin alongside the tongue of the pig.

Cartilaginous flap that covers the glottis to prevent food from entering the larynx and trachea when swallowing.

Opening in oral cavity that leads from nasopharynx to the larynx & trachea

Granular organ located along left margin of the duodenum. Produces digestive enzmes and a variety of hormones.

Canal which digestive enzymes from pancreas are transported to the duodenum.

Tubule through which bile is transported from liver to gallbladder and gallbladder to duodenum.

Ductless vascular organ in abdomina cavity. Stores blood, recycles worn out red blood cells and makes lymphocytes.

First portion of the small intestin; functions primarily in final stages of chemical digestion and begins process of nutrient absorption.

Distal portion of small intestine extending from the jejunum to the cecum; responsible for absorption of nutrients.

Middle portion of small intestine extending from duodenum to ileum, responsible for nutrient absorption.

Blind projection located at the junction of ileum and colon, serves as a sac where fermentation of cellulose occurs.

From cecum to rectum, large intestine, reabsorption of water that has been added through digestive process.

Reabsorb water and produce dry, concentrated feces.

Opening of rectum through which undigested food (feces) expelled from body

Large portal that carries nutrient rich and toxin laden blood from small intestines and pancrease to liver for detox and regulation before blood goes throughout rest of the body.

• Artery: Paired vessels that carry blood from fetus to the placenta
• Vein: Single vessel that carries O2 and nutrient rich blood to the fetus from the fetal side of the placenta.

Produces sperm and hormones (reproductive organ of male)

Tube connected to the epididymis that transports sperm from the testis through the epididymis to the urethra during ejaculation.

Reproductive organ in females, produces eggs and hormones

Tube by which the egg, leaving the ovary, is carried to the uterine horns

Region which embryonic development occurs.

Female reproductive canal leading from the cervis to the urogenital sinus.
