Endocrine/Urinary system Flashcards
chemical messengers that are secreted directly into the blood, which carries them to organs and tissues of the body to exert their functions.
Hormones
an organic compound with four rings arranged in a specific configuration.
Steroid
hormones that have other endocrine glands as their target.
Tropic hormones
also known as somatotropin, is a peptide hormone that stimulates growth, cell reproduction, and cell regeneration in humans and other animals.
Growth hormones
a pea-sized conical mass of tissue behind the third ventricle of the brain, secreting a hormonelike substance in some mammals.
Pineal body
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.
Hypothalamus
A pea-sized body attached to the base of the brain.
Pituitary gland
a large ductless gland in the neck that secretes hormones regulating growth and development through the rate of metabolism.
Thyroid gland
small endocrine glands in the neck of humans and other tetrapods that produce parathyroid hormone.
Parathyroid gland
Either of two small endocrine glands, one located above each kidney.
Adrenal gland
a large gland behind the stomach that secretes digestive enzymes into the duodenum.
Pancreas
an organ that produces gametes; a testis or ovary.
Gonads
each of a pair of organs in the abdominal cavity of mammals, birds, and reptiles, excreting urine.
Kidneys
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.
Nephrons
an almost insoluble compound that is a breakdown product of nitrogenous metabolism.
Uric acid
