Flashcards in Endocrine/urinary system Deck (24):
1

Hormones

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.

2

Steroids

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.

3

Tropic Hormones

A tropic hormone is a hormone that stimulates an endocrine gland to grow and secrete it's hormones.

4

Growth hormone

a hormone that stimulates growth in animal or plant cells, especially (in animals) a hormone secreted by the pituitary gland.

5

Pineal body

a pea-sized conical mass of tissue behind the third ventricle of the brain, secreting a hormonelike substance in some mammals.

6

Hypothalamus

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.

7

Pituitary gland

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.

8

Thyroid gland

a large ductless gland in the neck that secretes hormones regulating growth and development through the rate of metabolism.

9

Parathyroid gland

are small endocrine glands in the neck of humans and other tetrapods that produce parathyroid hormone.

10

Adrenal gland

Either of two small endocrine glands, one located above each kidney.

11

Pancreas

a large gland behind the stomach that secretes digestive enzymes into the duodenum.

12

Gonads

an organ that produces gametes; a testis or ovary.

13

Kidneys

each of a pair of organs in the abdominal cavity of mammals, birds, and reptiles, excreting urine.

14

Nephrons

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.

15

Uric acid

an almost insoluble compound that is a breakdown product of nitrogenous metabolism. It is the main excretory product in birds, reptiles, and insects.

16

Creatinine

a compound that is produced by metabolism of creatine and excreted in the urine.

17

Nitrogenous waste

Any metabolic waste product that contains nitrogen. Urea and uric acid

18

Urea

a colorless crystalline compound that is the main nitrogenous breakdown product of protein metabolism in mammals and is excreted in urine.

19

Urethra

the duct by which urine is conveyed out of the body from the bladder, and which in male vertebrates also conveys semen.

20

Urine

a watery, typically yellowish fluid stored in the bladder and discharged through the urethra

21

Urinary bladder

is a hollow muscular organ that collects urine from the kidneys before disposal by urination

22

Electrolyte balance

are minerals in your body that have an electric charge.

23

Intracellular fluid

of the body may be classified into two main divisions: the fluid within cells.

24

Extracellular fluid

or extracellular fluid volume usually denotes all body fluid outside the cells.
