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
