| external nares | pigs nostrils |
| stomach | the stomach is located between the liver and the large intestine. The function of the stomach is it stores food temporarily, releasing chyme in small amounts into the small intestine |
| lungs | the lungs are located superficial to the heart, and deep to the lungs.This is the large paired structure in the thoracic cavity that is the site of gas exchange in the body.The function of the lungs is |
| The scientific name of the pig? | sus scrofa |
| the underside of the pig? | ventral |
| By measuring the pig you can determine? | the pigs age |
| This structure carries blood from the placenta to the fetus, and vice versa. | the umbilical cord |
| This structure is a large, flat tissue at the bottom of the thoracic cavity that aids in breathing | diaphram |
| This is the large air tube that carries gases between the outside world and the lungs. It has cartilaginous rings that help keep it from collapsing | trachea |

| proximal | closer to the trunk |
| This structure moves oxygenated blood out of the heart and into the the body via arteries | Aorta |
| lateral | toward the side of the body. |
| This structure is located just above the stomach and produces bile. It aids in storage of amino acids and in digestion | Liver |
| This structure lies dorsal to the stomach and stores and produces red blood cells | spleen |
| This structure is held together by the mesentery and is responsible for absorption of nutrients. This is where final digestion takes place. | Small Intestine |
| This is the part of the digestive system that is responsible for the absorption of water. | Large Intestine |
| This is one member of the paired structure that acts to filter the blood and urine in the body. | Kidney |
| This is the large sac that stores urine. | Urinary Bladder |
| anterior/cranial | toward the head end of the body. |
| distal | farther from the trunk. |
| superficial | lying closer t the body's surface. |
| dorsal | toward the back of the body. |
| The name of the tissue that hold the small intestine in place | mesentery |
| a blood vessel that carries blood from the capillaries toward the heart. | vein |
| the passageway from the ovaries to the outside of the body. | oviduct |
| is a tube that connects the urinary bladder to the outside of the body. In males, it travels through the penis, and carries semen as well as urine. In females,it is shorter and emerges above the vaginal opening. | urethra |
| is the part of the neck and throat situated immediately posterior to the mouth and nasal cavity, and cranial, or superior, to the esophagus, larynx, and trachea. | pharynx |
| is a pouch, connecting the ileum with the ascending colon of the large intestine. | caecum |
| carry blood from the heart to the lungs.that *(carry deoxygenated blood) | pulmonary arteries |
| is a large blood vessel that carries blood from the lungs to the left atrium of the heart. | pulmonary vein |
| is a chamber which collects blood from an atrium | ventricle |
| either of two large veins that return oxygen-depleted blood to the right atrium of the heart | vena cava |
| lying under or below | under |
| is a small organ that aids digestion and stores bile produced by the liver. | gall bladder |
| muscular tubes that propel urine from the kidneys to the urinary bladder. | ureters |
| also called cuspids, are relatively long, pointed teeth | cainine |
| two very fine tubes leading from the ovaries into the uterus. | fallopian tubes |
| is a shunt connecting the pulmonary artery to the aortic arch. It allows most of the blood from the right ventricle to bypass the fetus' fluid-filled lungs | Ductus arteriosus |
| organ in the female reproductive system in which a fertilized egg can develop | uterus |
| are the organs that, in mammals, produce milk for the sustenance of the young. | mammary glands |
| are a class of vertebrate, air-breathing animals whose females are characterized by the possession of mammary glands while both males and females are characterized by sweat glands, hair | mammal |
| food tube connecting the mouth and the stomach | esophagus |
| is a hollow finger-like projection that hangs from the occum at the junction between the small intestine and the large intestine. | appendix |
| semilunar valve of the heart that lies between the right ventricle and the pulmonary artery and has three cusps. | pulmonary valve |
| one of several most distal parts of a limb—fingers, thumbs, and toes on hands and feet | digit |
| tissue that prevents blood from flowing backward from the right ventricle to the right atrium. | tricuspid valve |
| the first section of the small intestine; the shortest part of the small intestine, where most chemical digestion takes place. | duodenum |
| The large air tubes leading from the trachea to the lungs that convey air to and from the lungs. | bronchi |
| is a dual-flap,valve in the heart that lies between the left atrium and the left ventricle. | mitral valve |
| is an organ in the digestive and endocrine system,producing several important hormones, including insulin,secreting pancreatic juice containing digestive enzymes that pass to the small intestine. | pancreas |
| part of the male reproductive system,a narrow, tightly-coiled tube connecting the efferent ducts from the rear of each testicle | epidiymis |
| the middle section of the small intestine | Jejunum |
| is an opening at the opposite end of an animal's digestive tract from the mouth. Its function is to control the expulsion of feces, unwanted semi-solid matter produced during digestion | anus |
| are blood vessels that carry blood away from the heart. This blood is normally oxygenated | artery |
| where waste products of the body and reproductive fluids are expelled to the environment outside of the body cavity. | urogenital opening |
| nipples; tiny bumps that are located on the ventral surface of BOTH sexes. | mammary papillary |
| A conical sac of fibrous tissue which surrounds the heart and the roots of the great blood vessels. | pericardial sac |
| is one of the valves of the heart. | aortic valve |
| is a thin horizontal bony plate of the skull, located in the roof of the mouth. It spans the arch formed by the upper teeth. | Hard palate |
