Flashcards in Chapter 21- PVS and Lymphatic System Deck (73)
The major artery supplying the arm is the __, which runs in the biceps-triceps furrow of the upper arm and surfaces at the antecubital fossa in the elbow medial to the biceps tendon.
The brachial artery bifurcated into the __ and __ .
ulnar and radial
Peripheral artery disease affects ___ vessels and refers to arteries supplying the limbs.
The major artery to the leg is the ___, which passes under the inguin ligament.
At the lower thigh, the femoral artery courses posteriorly which then it is called the ___.
The anterior tibial artery travels down the front of the leg on the dorian of the foot, where it becomes the ____.
The the back of the leg, the ___ artery travels down behind the medial malleolus and forms the plantar arteries in the foot.
The function of the arteries is to ___.
supply oxygen and essential nutrients to the cells.
a deficient supply of oxygenated arterial blood to a tissue caused by obstruction of a blood vessels.
The course of veins is ___ to the course of arteries.
Body has more ___, and they lay ___ to the skin.
Function: to drain deoxygenated blood and it’s waste products from tissue and return it to the heart.
veins are called capacitance vessels because ___
of their ability to stretch.
Deep veins in the leg:
the femoral and popliteal veins
Superficial veins in the leg:
the great and small saphenous
connecting veins that join the deep and superficial veins.
The veins do not have a pump to generate their blood flow so they need a _____
mechanism to keep blood moving
The mechanism is accomplished by:
contracting skeletal muscles, pressure gradient caused by breathing, and intraluminal valves.
In the legs, the mechanism for venous flow is called ____
calf pump or peripheral heart.
Dilated and tortuous (varicose) veins create ____ valves leading to increased venous pressure, which further dilated the vein.
Lymphatic system retrieves what and from/to where?
excess fluid and plasma proteins from the interstitial spaces and returns them to the bloodstream.
Caused by the pumping action of the heart and pushed somewhat more fluid out of the capillaries than the venules can absorb.
pulls interstitial fluid back into the venules
colloid osmotic pressure
The right lymphatic duct empties into the ____.
subclavian vein. It drains the Right side of the head, neck, right arm, right side of the thorax, right lung, and pleura, right sid rod the heart, and right upper section of the liver.
The thoracic duct drains the ____ and empties it into the ___.
Rest of the body, and empties into the left subclavian vein.
Lymphatic system functions:
Conserve fluid and plasma proteins that leak out of capillaries
Form a major part of immune system that defends body against disease
absorbs lipids from intestinal tract
small oval clumps of lymphatic tissue located at intervals along vessels
the ___ groups of nodes are accessible to inspection and palpation and give clues to the status of the lymphatic system.
located in the left upper quadrant of the abdomen
