parasite:An organism that absorbs nutrients from a living organism.
parturition:The act of giving birth.
passive transport:Diffusion of molecules across a biological membrane without the assistance of carrier proteins (this term is used in opposition to "facilitated diffusion").
pelvis:The complex bony structure that in everyday parlance is called the hip bone.
urea:It is the primary nitrogenous component of urine in mammals and amphibians.
ureter:Either of the tubes leading from the kidneys to the bladder.
abdomen:the belly.
acid:Any substance that increases a solution's hydrogen ion concentration.
mammal: A member of the vertebrate class Mammalia.
marrow:Flexible tissue present in the hollows of bones.
metabolism:The chemical processes, taken as a whole, occurring within an organism.
active transport:The transport by a carrier protein of a molecule through a plasma-membrane against its concentration or electrochemical gradient.

chlorophyll:The green coloring matter found inside chloroplasts; in photosynthesis it catalyzes the combination of carbon dioxide with water to form carbohydrates.
cornea:The transparent external layer of the eye that overlies the iris.
dehydrate:To reduce or entirely remove the water content of a substance or body.
digestion:The process by which food is broken down into a form that can be absorbed by the body.
diffusion:The tendency of a substance to move in the direction toward which it is less concentrated.

ejaculation:Discharge of fluid from a duct, in particular from the male urethra, or vaginal glands.
embryo:The earliest of stage of development of a plant or animal.
epiglottis:The mucous-covered flap that closes the glottis.
epilepsy:A chronic neurological disorder characterized by periodic losses of consciousness, which may be accompanied by seizures.

fertilization:The union of a male and a female gamete to form a zygote.
gene:A unit of hereditary information located on a chromosome.
genitals:The external reproductive organs.
isomer:Any of two or more chemical compounds with the same molecular formula, but differing in structure.

rabid:affected by rabies.
nasal:Pertaining to the nose.
necrotic:Dead or dying
virology:The study of viruses.
vitamin:Any of a wide variety of chemical substances required by the body's metabolism, but that cannot be synthesized by the body.
vomit:the ejection of stomach contents through the mouth and nose.
wood:A hard, fibrous tissue found in many plants.
