Chapter 20: Peripheral Vascular System And Lymphatic System Flashcards
Arteries in the arm
Brachial
Radial/ulnar
Deep/superficial palmar arches
Arteries in the leg
Femoral&Popliteal (deep)
Dorsalis pedis
Posterior tibial
Ischemia
Deficient supply of oxygenated arterial blood to tissue caused by an obstruction of a blood vessel
Peripheral Artery Disease
Affects noncoronary arteries and usually refers to arteries supplying the limbs. Usually caused by atherosclerosis
Muscle fibers
Controls amount of blood delivered to the tissues
Veins
Absorb CO2 and waste products from the periphery and carry them back to the heart
3 mechanisms that help return venous blood to the heart
1) the contracting skeletal muscles that milk the blood proximally, back toward the heart
2) pressure gradient caused by breathing, inspiration makes the thoracic pressure decrease and abdominal increase
3) intraluminal valves, ensures unidirectional flow
Related organs in the lymphatic system
Spleen, tonsils, thymus
Where are lymph nodes accessible ?
Cervical, axial lady, epitrochlear, inguinal nodes
Amplitude of pulses
3+, increased, full, bounding
2+, normal
1+, weak
0, absent
Lymphedema
The swelling of an extremity caused by an obstructed lymph channel
Pulsus paradoxus
Beats have weaker amplitude w inspiration and stronger amplitude with expiration
Claudication is caused by
Arterial insufficiency
A water-hammer or corrigan pulse is associated with
Aortic valve regurgitation
Veins
Absorb CO2 and waste products from the periphery and carry them back to the heart
