when two blood types are mixed together, blood clots will form. (clumping of blood)

Question 11

describe cilia

Answer 11

lines the nasal cavity, trap and filter particles that are inhaled.

Question 11

inspiration is the process of?

Answer 11

taking air into the lungs.

Question 12

Answer 12

the epiglottis covers the trachea when food is being swallowed.

during inspiration(taking air into the lungs) the epiglottis allowed air to enter the trachea.

Question 13

expiration, larynx

Answer 13

Question 14

bronchi, bronchioles

Answer 14

trachea branches into two bronchi, each of which leads to a lung. bronchi branch into smaller tubes called bronchioles

Question 15

alveoli, inspiration

Answer 15

alveoli fill with air during inspiration.

Question 16

cilia that line the walls of air passageways do what?

Answer 16

clean the inspired air

Question 17

the rate of breathing is controlled by cells within

Answer 17

the brain

Question 18

how is most carbon dioxide transported in blood?

Answer 18

as bicarbonate IONS, when CO2 defuses into plasma it interacts with an enzyme that converts CO2 into carbonic acid. bicarbonate ions are very soluble in plasma.

Question 19

leukocytes, phagocyte

Answer 19

leukocytes help defend the body from diseases.

phagocytes is a type of leukocyte that engulfs invading microorganisms.

Question 20

antigen, antibody

Answer 20

an antigen is a protein of carbohydrates that causes the body to produce antibodies, which are defensive proteins.

Question 21

erythrocyte, hemoglobin

Answer 21

erythrocytes synthesize large amounts of hemoglobin, which carries oxygen.

Question 22

platelet, fibrin

Answer 22

both are involved with blood clotting

Question 23

when oxygen is carried by blood it is bonded to

Answer 23

hemoglobin
