Front 1

tubelike passageway for food, liquid, and air

Back 1

pharynx

Front 2

tiny, thin walled, grapelike clusters at the end of each bronchiole that are surrounded by capillaries; co2 and oxygen exchange takes place

Back 2

alveoli

Front 3

airway to which the vocal cords are attached

Back 3

larynx

Front 4

muscle beneath the lungs that contracts and relaxes to move gases in and out of the body

Back 4

diaphragm

Front 5

air-conducting tube that connects the larynx with the bronchi; is lined with mucous membranes and cilia, and contains strong cartilage rings

Back 5

trachea

Front 6

lung disease in which the alveoli enlarge

Back 6

emphysema

Front 7

two short tubes that branch off the lower end of the trachea and carry air into the lungs

Back 7

bronchi

Front 8

lung disorder in which the bronchial tubes contract quickly and cause shortness of breath, wheezing, coughing; may occur as an allergic reaction

Back 8

asthma

Front 9

system of excretory organs that rids the blood of wastes, controls blood volume by removing excess water, and balances concentrations of salts and water

Back 9

urinary system

Front 10

wastewater that contains excess water, salts, and other wastes that are not reabsorbed by the body

Back 10

urine

Front 11

bean-shaped urinary system organ that is made up of about 1 million nephrons and filters blood, producing urine

Back 11

kidney

Front 12

tiny filtering unit of the kidney

Back 12

nephron

Front 13

tube that carries urine from each kidney to the bladder

Back 13

ureter

Front 14

elastic, muscular organ that holds urine until it leaves the body through the urethra

Back 14

bladder

Front 15

tube that carries urine from the bladder to the outside of the body
