| knee | joint between upper leg and lower leg bones |
| eyelids | movable lid of skin that serves to cover and uncover the eye |
| neck | part of the body that connects the head and trunk |
| trunk | the body |
| anus | the end of the digestive system |
| head | the foremost section of the body, attached to the trunk |
| snout | the projecting nose |
| spleen | filters blood and produces red blood cells |
| cardiac sphincter | junction of the esophagus and stomach |
| pyloric sphincter | junction of the stomach and small intestine |
| liver | large organ that aids in digestion produces bile |
| mesentery | membrane that helps support the intestine in the abdominal cavity |
| pancreas | organ that lies beneath the stomach and produces enzymes that aid in digestion |
| stomach | organ that prepares the food for absorption by both physical and chemical activity |
| small intestine | organ where nutrients from food broken down in the stomach pass through capillary walls into the blood |
| gall bladder | saclike organ connected to the liver that produces and stores bile |
| diaphragm | sheet of muscle extending the length of the abdominal cavity; controls breathing |
| large intestine | undigested wastes are collected and pushed by muscle action into a cavity |
| fallopian tubes | coiled tube carrying eggs from the ovary to the uterus; also called the oviducts |
| kidney | excretory organs in which liquid wastes are filtered from blood |
| urogenital papilla | external fleshy cone like projection ventral to the anus |
| urinary bladder | muscular saclike organ that stores urine |
| ureters | narrow tubes through which urine flows from the kidneys to the urinary bladder |
| vagina | organ that lies ventral to the uterus |
| ovaries | small, bean shaped organs in female that produce egg cells |
| uterus | structure anterior to the vagina where fertilized eggs develop and fetus grows; also called the womb |
| urogenital sinus | tube where the urethra and vagina come together |
| urethra | tube which transports urine and reproductive cells out of the body |
| epididymis | coiled tube that lies dorsal to each testes |
| penis | long tube like organ that contains the urethra and carries urine and reproductive cells out of body of a male |
| testes | oval-shaped organs in males that produce sperm cells |
| scrotum | sac that contains the male reproductive organs |
| vas deferens | tube carrying sperm from the epididymis to the urethra |
| larynx | also known as the voice box |
| heart | muscular organ that pumps blood |
| lungs | respiratory organs where gasses exchange |

| left atrium | chamber that collects oxygenated blood from lungs |
| right atrium | chamber that collects deoxygenated blood from body |
| right ventricle | chamber that pumps deoxygenated blood to the lungs |
| left ventricle | chamber that pumps oxygenated blood into the aorta and out to the body |
| aorta | largest artery; carries oxygenated blood away from the body |
| pulmonary artery | only artery in body that contains deoxygenated blood - carries deoxygenated blood from heart to lungs |
| pulmonary veins | only veins in body that contain oxygenated blood - carries oxygenated blood from lungs to heart |
| posterior vena cava | veins that bring deoxygenated blood to the heart |
| anterior vena cava | veins that bring deoxygenated blood to the heart |
| hard palate | bony anterior section of the roof of the mouth |
| soft palate | muscular section of the roof of the mouth |
| nasopharynx | opening that carries oxygen from the nose to the trachea |
| epiglottis | prevents food from entering the trachea |
