what is the name of the vessels that carry lymph from the lymphatic capillaries into veins?
lymphatic vessels
once interstitial fluid enters the lymphatic vessels, what is it called?
lymph
what is the name of the inner region of a lymph node?
medulla
what kind of vessel takes lymph away from a lymph node?
efferent lymphatic vessel
the adenoids are enlarged _______
pharyngeal tonsils
which tonsils are found on the sides of the oral cavity?
palatine tonsils
why might a doctor feel in the groin area, under the arm, or on the side of the neck for lumps?
location of lymph nodes may correspond to location of infection/sickness
blood is filtered by which lymphatic organ in the adult?
spleen
which part of the spleen is involved in producing lymphocytes?
white pulp
where do T cells mature?
thymus
T/F: lymphatic vessels have a one way flow from the extremities to the heart
True
damage to the lymphatic system can lead to ____
edema or increase in tissue fluid
how does the use of medical leeches work for a region that has suffered trauma?
medical leeches are placed on the ends of the extremeties and drain the excess tissue fluid form the region, decreasing the edema and removing debris and some potential pathogens
what materials may be missing from the lymph leaving the node?
lymph is interstitial fluid that has passed into the lymphatic vessels. it carries tissue fluid, cellular debris, and microorganisms. since the function of the lymph node is to cleanse the tissue, the lymph traveling to the node should have more cell debris and potential microorganisms than the lymph traveling from the node
what effect would the removal of lymph nodes have on drainage of the upper extremity?
edema of pectoral region and upper limbs
What is an example of a mechanism by which blood from the deep veins can be returned to the heart (other than by standing on your head)?
wearing of compression sleeves
what does a sphygmomanometer measure?
blood pressure
to measure BP, what artery would you most commonly use?
brachial artery
if you have a BP of 140/80, what does the 80 represent?
Diastolic pressure
what is the clinical threshold for high BP in young adults?
140/90
when the first sound is heard during measurement with a BP cuff, what is measured?
systolic pressure
predict the BP of an individual with a sinus headache and postnasal drip
elevated BP
nicotine and caffeine both elevate BP. Explain how an increase in BP could have a negative effect on the cardiac output.
heart loses efficiency
how did the change in BP after exercise vary from those people who exercise 3-5x per week versus those who do not exercise?
lower BP if exercise trained
