A & P Lab Test 2

Front 1

Tunica intima

Back 1

lines the lumen of a Vessel intima= intimate/inside Closky packed cells form smooth surface that reduces friction and helps blood travel

Hint 1

Smooth, inside job (intimate)

Front 2

Tunica media

Back 2

Media-middle, is bulky And made of smooth muscle and elast ic tissue. Controlled by the sympathetic nervous system is active in changing the diameter of blood vessels alters BP& Peripheral resistance

Hint 2

Buff middle

Front 3

Terminal externa

Back 3

Outside of tunic, Composed of fibrous Connective tissue function as blood Vessel support And protection

Hint 3

Outside layer

Front 4

Artery Structure

Back 4

Artery walls are thicker than veins. the tunica media in arteries is thicker and more muscular because arteries are closer to the pumping Of the heart and have to expand and contract to a great degree. their walls must be strong enough to withstand Such pressure fluctuations

Front 5

Vein structure

Back 5

are farther away from the heart so they are much less muscular than arteries. their walls are thinner / but they have a larger lumen because pressure is lower but it has to return the same Amount of blood

Front 6

Ascending aorta

Back 6

branches into the left and right coronary arteries which provide oxygen to the heart

Front 7

Brachiocephalic trunk

Back 7

First major branch of the aortic arch Splits And divides into the right common Carotid artery and the right Subclavian

Front 8

Cardiac cycle (includes events of one complete heartbeat)

Back 8

both atria and Ventricles Contract and relax. • 1 Ventrical filling: Vertical filling and atrial contraction •2 ventricular systole: isovolumentric contraction • 3 early diastole: Isovolumetric relaxation, ventricular filling

Front 9

Systole

Back 9

Contraction of the heart

Front 10

diastole

Back 10

Period of relaxation of the heart

Front 11

Lub

Back 11

AV valve close at the beginning of Systole

Front 12

Dub

Back 12

Occurs when the SL Valve closes at the end of systole

Front 13

Lub-Dub

Back 13

heart sounds

Front 14

Pulse

Back 14

Alternate surges of pressure in the artery that occur with each beat of the left ventricle usually is heart rate which is 70-76 bpm

Front 15

Blood Pressure (BP)

Back 15

pressure exerted by the blood up on the walls of the blood vessels / measured by sphygmomanometer and expressed in millimeters of mercury

Front 16

Systolic pressure

Back 16

pressure during the peak of ventricular ejection usually 120mm HG

Front 17

Diastolic pressure

Back 17

Pressure during ventricular relegation Usually 80mm HG

Front 18

Sphygmomanometer

Back 18

Instrument used to take blood pressure blood pressure cuff

Front 19

Sounds of korotkoff

Back 19

as cuff pressure is released the examiner listens with a stethoscope Over the brachial artery for the characteristic sounds that indicate the resumption of blood flow into the forearm

Front 20

Arterial blood pressure

Back 20

Cardiac output (CO) x Peripheral resistance (PR)

Front 21

Upper respiratory system

Back 21

Nose pnarynrd & larynx

Front 22

Phaeryngotympanic tubes

Back 22

auditory or Eustachian tubes, which allow middle ear pressure to become equalized to atmospheric pressure. ( lets your ears pop)

Hint 22

Tympani=ear pharyngeo=mouth

Front 23

Cribriform plate

Back 23

horizontal plate of the ethmoid bone separating the cranial cavity From the nasal cavity

Front 24

Sphenoid sinus

Back 24

Sinus located within the sphenoid bone

Front 25

Posterior nasal apeture

Back 25

open passageway at the end of the nasal cavity leading into the pharynx

Front 26

Nasopharynx

Back 26

posterior (behind) to the nasal cavity and Continuous with it. lies above Soft palate it serves as only an air passage

Front 27

Pharyngeo tonsil

Back 27

(adenoids) important defense mechanism Of the pulmonary system? (google it later)

Front 28

Uvula

Back 28

Dangles from the back of the roof Of the mouth

Front 29

Oropharynx

Back 29

posterior (behind) the oral cavity and continuous with it through an archway Extends from the soft pallet to the epiglottis Conduit for food and air

Front 30

Palatine tonsil

Back 30

in the lateral Walls of the Oropharynx

Front 31

Lingual tonsils

Back 31

Cover the base of the tongue in the Oropharynx

Hint 31

Lingual= tongue

Front 32

Laryngpharnyx

Back 32
