Fetal Pig Dissection –
Structures and Functions
Digestive System
Canines
• Tear at food
Submaxillary Gland
• Secretes saliva and mucous to form bolus
Pharynx
• Opening to esophagus
Esophagus
• Transfers food from mouth to stomach via
peristalsis
Digestive System
Stomach
• Mechanical and chemical digestion
Pyloric sphincter
• Controls gastric emptying
Small Intestine
Duodenum
• Chemical digestion and absorption of
nutrients
Ileum
• Wraps up aborption
Digestive System
Pancreas
• Secretes digestive enzymes to duodenum
Liver
• Produces bile to emulsify fats
Gall Bladder
• Storage of bile
Bile Duct
• Transfers bile from gall bladder to
duodenum
Digestive System
Colon (l. intestine)
• Water absorption to produce feces
• Bacteria to aid w/undigested food
Rectum
• Storage of feces prior to elimination
Anus
• Allows feces to exit the rectum
Digestive System
Spleen
• Destruction of old blood cells
• Stores RBC
• Manufactures WBC
Thymus
• Produces hormones involved in the processing
and maturation of special lymphocytes called Tcells
• Replaced by connective tissue and fat during
puberty
Respiratory System
Epiglottis
• Covers trachea during swallowing reflex
Trachea
• Transfers air from nasal cavity to bronchi
Larynx (vocal cords)
• Voice resonance
Bronchus
• Transfer air from trachea to
bronchioles/alveoli
Respiratory System
Lungs
• Site of gas exchange b/w air and
capillaries in the alveoli
Diaphragm
• Contracts to draw air into lungs
Urinary System
Kidney
• Filtration, secretion, and reabsorption of
blood
Adrenal gland
• Produces hormones
Hilus
• Entering into kidney for r. arteries, r. veins,
and ureters
Bladder
• Temporary storage of urine
Urinary System
Urethra
• Carries urine from the bladder to the
urethral orifice
Urinary
System
RENAL
ARTERY
HILUM
Circulatory System
Heart
• Pumps blood to systemic and pulmonary circuits
• Right ventricle
– Receives from RA and pumps to pulm. Arteries
• Left ventricle
– Receives from LA and pumps to aorta
• Right atrium
– Receives blood from vena cava’s and coronary sinus
• Left atrim
– Receives bloood from pulm. veins
Auricles
• Increase volume of blood in the atria
Epicardium
• Protects the heart; outer covering
Circulatory System
External Jugular
• Drains blood from the right side of head and
neck region (sends to RA)
Internal Jugular
• Drains the head and deep regions of face and
neck
Common carotid arteries
• Deliver blood to the brain
Circulatory System
Aorta
• Receives blood from LV and delivers it to the systemic
circuit
Abdominal aorta
• Main extension of the aorta that supplies the abdominal
cavity and its many arteries
A. Vena Cava (superior)
• Drains blood from head, neck, and ventral portion of
the body and returns blood back to the RA
P. Vena Cava (inferior)
• Drains blood from the abdomen and dorsal portion of
body and returns it to the heart
Circulatory System
Umbilical artery
• Delivers blood from fetus to placenta;
deoxygenated
Umbilical vein
• Delivers blood from placenta to fetus;
oxygenated
Umbilical cord
• Attaches to placenta; nourishes fetus
Circulatory System
Renal veins
• Drains the kidneys; clean blood back to
heart
Renal arteries
• Delivers blood to the kidneys; supplies
oxygen and is cleaned of cellular wastes
Circulatory System
Pulmonary arteries
• RA  lungs
Pulmonary veins
• Lungs  LA
Subclavian artery
• Major branch of aorta; supplies vertebral region
and thyrocervical areas with blood
Subclavian vein
• Delivers blood to the superior vena cava from
the vertebral and thyrocervical areas
Circulatory System
Femoral vein
• Delivers blood from the thigh to the external
iliac that joins the IVC to deliver blood back to
heart
Femoral artery
• major artery of the leg; supplies many branches
with blood for the thigh
• Branches from the common iliac
Anterior and posterior tibial arteries
• Delivers blood to the lower leg and foot
Reproductive System
Ovary
• Produces eggs
Oviducts
• Transfers eggs to uterus
Uterus
• Development of kits; divided to house a litter
Vagina
• Birth canal; receives penis and transfers semen to
cervix/uterus
Reproductive System
Testis
• Produce sperm
Scrotum
• Surrounds and protects the testes
Epididymis
• Collect and store maturing sperm cells
Reproductive System
Vas deferens
• Transfers sperm from epididymis to urethra
Seminal vesicle
• Seminal fluid that contains fructose and
prostaglandins
Prostate gland
• Milky fluid that contains enzymes and adjusts
vaginal pH
Reproductive System
Penis
• Transfers semen to vaginal canal
