Eye and ear and kidney

Question 1

Auricle

Answer 1

(outer ear)
collects and directs sound waves to auditory canal

Question 2

Auditory canal

Answer 2

(outer ear)
Directs soundwaves to eardrum

Question 3

tympanic membrane (eardrum)

Answer 3

(Middle ear)
Translates vibrations to ossicles

Question 4

Ossicles

Answer 4

(middle ear)
amplify pressure of sound waves as they are transmitted to oval window

Question 5

Oval window

Answer 5

(middle ear)
Transmits vibrations from stirrup to fluid filled cochlea

Question 6

Round window

Answer 6

(inner ear)
Equalises pressure in the cochlea when oval window vibrates

Question 7

Eustachian tube

Answer 7

(inner ear)
equalises pressure on both sides of eardrum

Question 8

Cochlea

Answer 8

(inner ear)
Vibrations cause hair cells to bend producing a nerve impulse

Question 9

Auditory nerve

Answer 9

(inner ear)
Transmits dound information to brain

Question 10

Conjuctiva

Answer 10

Protects and lubricates eye with tears and mucous

Question 11

Cornea

Answer 11

barrier protection for the eye and refracts light rays

Question 12

Sclera

Answer 12

Provides structure and support and maintains shape of the eyeball

Question 13

Choroid

Answer 13

Provides blood supply to the eye

Question 14

Aqueous humour

Answer 14

Maintains pressure, provides eye nutrition and refracts light

Question 15

Iris

Answer 15

controls amount of light that enters eye

Question 16

Pupil

Answer 16

Allows entry of light into eye

Question 17

Lens

Answer 17

main refractive structure in the eye that focuses light onto retina

Question 18

Cilary body/muscles

Answer 18

Holds lens in position and changes its thickness

Question 19

Vitreous humour

Answer 19

Maintains spherical shape of eye and has some refractive ability

Question 20

Retina

Answer 20

Converts light to electrochemical signals

Question 21

Macula

Answer 21

allows for sharp, clear, straight-ahead vision

Question 22

Optic nerve

Answer 22

Transmits nerve impluses from retina to brain

Question 23

eye muscles

Answer 23

rotates the eyeball within socket

Question 24

Glomerus

Answer 24

FILTRATION
Blood cells and large proteins cannot pass through
water and solutes passively pass through

Question 25

Proximal convoluted tubule

Answer 25

SECRETION - active transport of unwanted substances such as drugs from blood into tubule REABSORPTION - primarily passive return of water, ions, and glucose from filtrate into blood

Question 26

Loop of henle

Answer 26

REABSORPTION main site of water reabsorption back into blood. it is impermeable to ions

Question 27

Distal convoluted tubule

Answer 27

REABSORPTION further reabsoption of ions is regulated by ADH

Question 28

Nephron

Answer 28

FILTRATION contains filtering structure called glomerulus and tubule
