NR 304 CHAPTER 21 || 100% Accurate Answers.
Arteries Structure and Function correct answers Heart pumps freshly oxygenated blood through
arteries to all body tissues.
Function of arteries is to supply oxygen and essential nutrients to tissues.
peripheral arterial disease (PAD) correct answers blockage of arteries carrying blood to the legs,
arms, kidneys and other organs. Affects noncoronary vessels and refers to arteries affecting the
limbs.
The arteries in the arm consist of? correct answers The Brachial Artery (at the elbow), Radial
Artery (outside of wrist) and the Ulnar Artery (inside of wrist).
Arteries of the leg correct answers femoral, popliteal, dorsalis pedis, posterior tibial
Veins in the leg correct answers Deep—femoral and popliteal
Superficial—great and small saphenous
Perforators—connecting veins that join two sets
The femoral is a deep vein along the posterior and medial aspect of the thigh, while the great
saphenous vein is a superior vein, anterior to the femoral.
The perforating vein connects the two.
On the lower leg, the small saphenous vein runs up the posterior calf.
Vein structure correct answers veins also have three layers: a thin outer layer, a middle layer and
a smooth inner layer; veins are less muscular than arteries and have less elasticity.
, Course of veins parallels that of arteries : Body has more veins, and they lie closer to skin
surface.
Veins are called capacitance vessels because of their ability to stretch.
function of veins correct answers to drain deoxygenated blood and its waste products from
tissues and return it to heart.
Vein accessible to examination correct answers Jugular veins and Veins in the leg
venous flow correct answers Is a Mechanism to keep blood moving by: Dilated and tortuous
(varicose) veins create incompetent valves leading to increased venous pressure, which further
dilates the vein.
venous flow mechanism correct answers -Contracting skeletal muscles milk the blood back to
the heart
-Pressure gradient caused by breathing
-Intraluminal valves ensure unidirectional flow
lymphatic ducts correct answers drain tissues of body and move lymph into major veins
lymphatic drainage correct answers Cervical nodes: drain head and neck
Axillary nodes: drain breasts and upper arm
Epitrochlear nodes: drains the hand and lower arm
Inguinal nodes: drain lymph from lower extremity, genitalia, and abdomen
cervical nodes correct answers lymph nodes in the neck region drain head and neck
