Flashcards in Endocrine/urinary system Deck (24):
a regulatory substance produced in an organism and transported in tissue fluids such as blood or sap to stimulate specific cells or tissues into action.
any of a large class of organic compounds with a characteristic molecular structure containing four rings of carbon atoms (three six-membered and one five). They include many hormones, alkaloids, and vitamins.
A tropic hormone is a hormone that stimulates an endocrine gland to grow and secrete it's hormones.
a hormone that stimulates growth in animal or plant cells, especially (in animals) a hormone secreted by the pituitary gland.
a pea-sized conical mass of tissue behind the third ventricle of the brain, secreting a hormonelike substance in some mammals.
a region of the forebrain below the thalamus that coordinates both the autonomic nervous system and the activity of the pituitary, controlling body temperature, thirst, hunger, and other homeostatic systems, and involved in sleep and emotional activity.
the major endocrine gland. A pea-sized body attached to the base of the brain, the pituitary is important in controlling growth and development and the functioning of the other endocrine glands.
a large ductless gland in the neck that secretes hormones regulating growth and development through the rate of metabolism.
are small endocrine glands in the neck of humans and other tetrapods that produce parathyroid hormone.
Either of two small endocrine glands, one located above each kidney.
a large gland behind the stomach that secretes digestive enzymes into the duodenum.
an organ that produces gametes; a testis or ovary.
each of a pair of organs in the abdominal cavity of mammals, birds, and reptiles, excreting urine.
each of the functional units in the kidney, consisting of a glomerulus and its associated tubule, through which the glomerular filtrate passes before emerging as urine.
an almost insoluble compound that is a breakdown product of nitrogenous metabolism. It is the main excretory product in birds, reptiles, and insects.
a compound that is produced by metabolism of creatine and excreted in the urine.
Any metabolic waste product that contains nitrogen. Urea and uric acid
a colorless crystalline compound that is the main nitrogenous breakdown product of protein metabolism in mammals and is excreted in urine.
the duct by which urine is conveyed out of the body from the bladder, and which in male vertebrates also conveys semen.
a watery, typically yellowish fluid stored in the bladder and discharged through the urethra
is a hollow muscular organ that collects urine from the kidneys before disposal by urination
are minerals in your body that have an electric charge.
of the body may be classified into two main divisions: the fluid within cells.
