biological process - a process occurring in living organismsagglutination - a clumping of bacteria or red cells when held together by antibodies (agglutinins) aging, senescence, ageing - the organic process of growing older and showing the effects of increasing age anovulation - the absence of ovulation due to immaturity or post-maturity or pregnancy or oral contraceptive pills or dysfunction of the ovary antisepsis, asepsis - the process of inhibiting the growth and multiplication of microorganisms autoregulation - (physiology) processes that maintain a generally constant physiological state in a cell or organism bloom, blooming - the organic process of bearing flowers; "you will stop all bloom if you let the flowers go to seed" carbon cycle - the organic circulation of carbon from the atmosphere into organisms and back again crossing over, crossover - the interchange of sections between pairing homologous chromosomes during the prophase of meiosis digestion - the organic process by which food is converted into substances that can be absorbed into the body eburnation - a change that occurs in degenerative joint disease in which bone is converted into a dense smooth substance resembling ivory ecchymosis - the escape of blood from ruptured blood vessels into the surrounding tissue to form a purple or black-and-blue spot on the skin effacement - shortening of the uterine cervix and thinning of its walls as it is dilated during labor erythropoiesis - the process of producing red blood cells by the stem cells in the bone marrow phylogenesis, phylogeny, evolution - (biology) the sequence of events involved in the evolutionary development of a species or taxonomic group of organisms expression - (genetics) the process of expressing a gene extravasation - the process of exuding or passing out of a vessel into surrounding tissues; said or blood or lymph or urine gastrulation - the process in which a gastrula develops from a blastula by the inward migration of cells glycogenesis - the formation in animals of glycogen from glucose growing, growth, ontogenesis, ontogeny, maturation, development - (biology) the process of an individual organism growing organically; a purely biological unfolding of events involved in an organism changing gradually from a simple to a more complex level; "he proposed an indicator of osseous development in children" heredity - the biological process whereby genetic factors are transmitted from one generation to the next implantation, nidation - (embryology) the organic process whereby a fertilized egg becomes implanted in the lining of the uterus of placental mammals inhibition - (physiology) the process whereby nerves can retard or prevent the functioning of an organ or part; "the inhibition of the heart by the vagus nerve" |
