Ch. 21 (Peripheral Vascular & Lymphatics) Flashcards
What is classifed as the vessels in our body?
vascular system
blood and lymph
What type of artery is located in front of the ears?
temporal artery
What type of artery is located in the neck?
carotid artery
What type of artery is located above the elbow crease?
brachial artery
The brachial artery branches into what two arteries?
- ulnar artery
- radial artery
What type of artery is located by the wrist towards our thumb?
radial artery
What type of artery is located by the wrist towards our pinky?
ulnar artery
What happens with aging in the vascular system?
- vessel walls stiffen - rises systolic BP
What type of artery is located in the groin area?
femoral artery
What type of artery is located behind the knee?
popliteal artery
What type of artery is located on the inside of our ankle?
posterior tibial
What type of artery is located on the dorsum (top) of the foot?
dorsalis pedis
What peripheral vascular abnormality is described as a deficiency in oxygenated blood which can result in tissue death?
ischemia
What type of vessels lie closer to the skin surface, have thin walls and drain deoxygenated blood from the tissues and return it to the heart?
veins
What type of vessels lie deeper in the skin and have thicker walls?
arteries
What type of vein is located in the neck?
jugular vein
What type of veins are located in the arms?
arm veins
What type of vein are located in the legs?
leg veins (three different types)
What are the three different types of leg veins?
- deep veins
- superficial veins
- perforator veins (connect deep & superficial)
What are the three mechanisms that keep blood moving in the body?
- skeletal muscles (around walls of veins)
- inspiration (breathe in - abdominal pressure increases)
- intraluminal valves (valves ensure blood flows in one direction)
What type of vessels retrieve excess fluid from tissues and connects to the blood stream to reduce waste?
lymphatics
What type of lymph nodes are located under the arm?
axillary
What type of lymph nodes are located in the elbow area (between biceps and triceps)?
epitrochlear
not typically palpable - if is = sign of infection
What type of lymph nodes are located in the inner thigh by the groin?
inguinal
What abnormality is caused by the removal or blockage of a lymph vessel impairing that part of the body from draining properly?
lymphedema
Does lymphedema cause pitting?
no
