| Question | Answer |
|---|---|
| anus | hole/opening between the urogenital opening and the tail. Secretes poop |

| liver | left lobe and right lobe, brownish sacs. PRODUCES BILE! acts as a filter to remove toxins (harmful substances) and waste products from the blood |

| large intestine | shorter than the small intestine and it is responsible for the reabsorbing water and maintaining the fluid balance of the body. it processes undigested material, and stores waste |

| abdominal | stomach area |
| spleen | part of the immune system, filters out and destroys dead blood cells |
| rectum | sotres feces in teh digestive tract |
| pancreas | produces enzymes that digest food. |
| mesentery | thin transparent sheets of tissue that suspend and support certain portions of the small intestine in the abdomen |
| kidneys | lie below the digestive organs beneath the peritoneum. the main excretory organ and is responsible for extracting wastes and foreign substances from the blood stream. also helps with body fluid regulation |
| renal veins | carry filtered blood from the kidneys to the posterior vena cava (blue) |
| renal arteries | carry unfiltered blood from the aorta to the kidneys and are found beneath the renal veins (red) |
| ureters | urine filtered from the blood by the kidneys passes through these hollow tubes to be stored in the urinary bladder. Connects kidney to bladder |
| esophagus | the tube that carries food from the mouth to the digestive tract to the left of the trachea |
| trachea | supportive cartilage that ensures the airway remains open. the trachea carries air directly into the lungs |
| ovaries | contain all the developed eggs the female pig will ever have and they produce estrogen and progesterone. |
| oviducts | called FALLOPIAN tubes in humans. they recieve the egg from the ovaries at ovulation. |
| uterus | this is where the egg develops into a fetus |
| penis | a muscular organ that becomes stiff or erect when stimulated |
| scrotal sac | Holds the testes |
| testicles | where the sperm production takes place, they produce sex hormones |
| epididymae | a whitish mass of tightly coiled tubes cupped against the testicles. storage place for sperm before they enter the vas deferentia |
| vas deferens | tubes that carry sperm from the testes to the urethra |
| external nares | outer nostrils |
| epitrichium | fetal pig skin |
| pinnae/aricle | pig ears |
| median | middle |
| posterior | towards the bottom of the body |
| caudal | towards the bottom of the body |
| cranial | towards the head of the body |
| dorsal | back side |
| ventral | under side of pig |
| lateral | side of pig |
| distal | far away from the body (arms and legs) |
| anterior | towards the head of the pig |
| vein | blood vessel that returns blood back to the heart |
| ventricle | lower chamber of the heart that pumps blood out of the heart |
| capillary | small blood vessel that brings nutrients and oxygen to the tissues and absorbs carbon dioxide and waste products |
| mammary gland | produces milk to nourish the young |
| artery | large blood vessel that carries blood from the heart to tissues in the body |
| genital papilla | the flap that determines if its a boy or girl. Only females have a genital papilla. |
| duodenum | the first part of the small intestine. largely responsible for the breakdown of food in the small intestine |
| mammary papilla | nipples or teats |
| urogenital sinus | hole urine and sexual fluid go in and out of |
| stomach | sac for churning food and chemically digesting food |
| venules | small veins |
| urethra | tube through which urine passes when you empty your bladder |
| alveoli | grape shaped sacs near bronchi that hold air. it is the location of gas exchange |
| peritoneum | lines the cavity of the abdomen. SUPPORTS the abdominal organs |
| pharynx | food and air travel through. has the epiglottis |
| cartilaginous rings | around the trachea. keeps the trachea open for air to come in and out |
| caecum | a blind pouch at the beginning of the large intestine, absorbs water and salts from undigested foods before they continue on to the large intestine |
| pulmonary artery | carries oxygen poor blood to the lungs |
| pulmonary vein | carries oxygen rich blood to the heart |
| vena cava | two (superior and inferior) veins by which the blood is returned to the right atrium of the heart |
| aorta | main artery leaving the heart |
| ductus deferens | collects and holds the vas deferens |
| canine | type of teeth that are sharp and pointy (cut flesh) |
| ruminants | animal that chews cud |
| fallopian tube | allows an egg to pass between the ovary and the uterus |
| ductus arteriosus | blood vessel only in the fetus that connects pulmonary artery to the aorta |
| mammal | warm blooded with a spinal cord |
| thoracic | chest region |
| cervical | reproductive |
| superficial | close or on surface |
| umbilical cord | brings nutrients to babies |
| pulmonary valve | keeps blood from going back to the heart |
| digit | finger or toe |
| tricuspid valve | heart part that prevents blood from entering right atrium again |
| hard palate | ridges on top of mouth. interaction between this is important for the formation of some sounds |
| bronchioles | before alveoli and they are small air tubes that lead air to the lungs from the bronchi |
