exercse 19 and 20

correct order for the pathway of lymph from the stomach to the blood

D) 4, 3,2, 1, 5 4) intersitial fluid 3) lymph capillaries 2) lymphatic vessels and lymph nodes 1) thoracic duct 5) left subclavian vein

when the semilunar valves are open during a cardiac cycle, what occurs

I, II, IV, and V I- atrioventricular valves are closed II- ventricles are in systole IV- blood enters the aorta V- blood enters the pulmonary trunk

the two distinct heart sounds, described phonetically as lubb and dupp represent

blood turbulence associated with the closign of the atrioventricula and semilunar valves

which of the following statements is not true

both systolic and diastolic blood pressures can be obtained via the pulse method

the artery that is normally used to evaluate blood pressure is the

brachial artery

this x-ray examination is useful in detecting edema and

carcinoma

systole and diastole of both atria pulse systole and diastole of both ventricles is called

cardiac cycle

the thoracic duct starts in the lubar region as a dilation know as

cisterna chili

the heart has an intrinsic regulating system called the cardiac

conduction system

the period of the cardiac cycle when all valves are closed and pressure continues to climb withing the left venricle is called the period of

isovolumetric contraction

which of the following statements is true about the flow of lymoh

itis aided in its movement towards the thoracic region by a pressure gradient, it is maintained primarily by the milking action of mucles, it is possible because of valves in lymphatic vessles, all of the above

both the thoracic duct and the right lymphatic duct empty directly into the

junction of the internal jugular and subclavian veins

what is not a major site for lymphatic tissue

kidneys

rapping or thumping sounds heard clinically when blood pressure is being taken are called

korotkoff sounds

the typical ECG produces three clearly recognizable waves, the first wave which indicates depolarization of the atria is called the

p wave

the ******* tonsils are commonly removed by tonsilectomy

palatine

the *********** of the spleen consists of two types of tissue, red pulp and white pulp

parenchyma

the difference between systolic and diastolic pressure is called

pulse pressure

although the pulse may be detected in most surface arteries, pulse rate is usually determined on the

radial artery of the wrist

B cells in lymoh nodes produce certain cells that are responsible for the production fo antibodies, these cells are called

plasma cells

heart sounds provide valuable information about the

valves

lymphatic vessels have thinner walls than veins, but resemble veins in that they also have

valves

an average blood pressure value for an adult is

120/80

an average pulse pressure is

40 mm Hg

electrical impulses accompanying the cardiac cycle are recorded by

electrocardiograph

when ventricular pressure drops below atrial pressure, which phase of the cariac cycle occurs

atrial systole

various up and down impulses produced by an ECG are called

defelection waves

lymph is conveyed out of lymph nodes in the

efferent vessels

a major difference between the spleen and the lymph nodes is that

lymoh nodes have afferent and efferent lymphatic vessels, the spleen only has efferent lymphatic vessels

the x ray examination of lymphatic vessels and lymoh organs after they are filled with radiopaque substance is called

lymohangiogram

smalls masses of lymphatic tissue located along the length of the length of the lymphatic vessels are called

lymphaticnodules

lymphatic nodules in the lamina propria of a mucous membrane are collectively referred to as

malt

abnormal or peculiar heart sounds are called

murmers

during which phase of the cardiac cycle are all four chambers in diastole

relaxation period

which of the following is an important function of the lymphatic system

returning fluids and proteins to the cardiovascular system

all lymphatic vessels converge, get larger and eventually merge into tow main channels, the thoracic duct and the

right lymphatic duct

the spleen

serves as a storage site for blood platelets, is an organ in which phagocytosis of an aged red blood cell occurs, is a site of blood formation in the fetus all of the above

the instrument normally used to measure blood pressure is called a

sphygmomanometer

the largest mass of lymphatic tissue is the

spleen

the main collecting duct of the lymphatic system is the

thoracic duct

the red bone marrow and the ******* are the primary lymphatic organs because they product the lymphocytes for the immune system

thymus

what are major sites for lymphatic tissue

tonsils, thymus gland, spleen
