Chat with AIExam 17: Peripheral Vascular System and Lymphatic System
List the pulses accessible to examination.
(33) 
VerifiedThe following arteries are accessible to examination: temporal, carotid, aortic, brachial, ulnar, radial, femoral, popliteal, dorsalis pedis, and posterior tibial.
Relate the structure and functions of the lymph vessels.
(34) VerifiedThe lymphatic system provides an auxiliary system for fluid to flow from interstitial spaces to the bloodstream. The lymphatic capillaries are permeable to substances of high molecular weight, such as proteins. In addition, the lymphatic system forms a major part of the immune system and absorbs lipids from the intestinal tract. To achieve this special purpose, the lymphatic capillaries have a special structure; the endothelial cells are not connected to each other. The cells are attached by anchoring filaments to the connective tissue of the vessels, which start as microscopic open-ended tubes. The vessels have valves that cause them to appear as beads.
Explain the term "capacitance vessels."
(46) VerifiedVeins are called capacitance vessels because they are distensible and can therefore stretch and hold more blood when blood volume increases. This compensatory mechanism reduces stress on the heart.
Incorporate health promotion concepts when performing an assessment of the peripheral vascular system.
(34) Cite the location of superficial groups of lymph nodes that are accessible to examination.
(35) Describe the mechanisms that keep blood moving toward the heart in the venous system.
