Flashcards in Venous Return Deck (29):
Which three veins supply the heart?
Superior Vena Cava
Inferior Vena Cava
How does blood drain from the inferior sagittal sinus?
Inferior sagittal to straight to transverse to sigmoid to internal jugular
How does blood drain from the superior sagittal sinus?
Sagittal to transverse to sigmoid to internal jugular vein
What does the internal jugular vein drain?
drains the brain, superficial face, and neck
Where does the internal jugular vein go?
Unites with the subclavian vein (from arm) to form the large brachiocephalic vein (both left and right), to the superior vena cava
What does the external jugular drain?
drains the exterior of the cranium and facial muscles
Where does the external jugular vein go?
Empties into the subclavian veins on each side
How would blood drain from the superior sagittal sinus to the heart?
superior sagittal sinus to transverse to sigmoid to internal jugular vein to brachiocephalic vein to superior vena cava to heart
The largest portion of blood volume at rest, __% is in systemic veins and venules, _% in capillaries, __% in arteries and arterioles, and the rest is in the pulmonary circuit.
What do digital veins drain into?
Superficial OR deep palmar arches
How are the radial and ulnar veins formed?
By the superficial and deep palmar arches
What forms the brachial vein?
At the elbow, the radial and ulnar veins combine to form the brachial vein
The brachial vain meets the _____ vein to form the axillary vein
How does the axillary vein drain?
The axillary vein → subclavian vein → brachiocephalic vein → superior vena cava
Which vein goes up the lateral aspect of the arm to the axillary vein?
How does blood drain from the fingers to the heart?
Digital to deep palmar arch to ulnar to brachial to axillary to subclavian to brachiocephalic to superior vena cava
What is the median cubital vein?
A short anastomosis between the cephalic and basilic veins that obliquely crosses the anterior bend of the elbow, the cubital fossa. It is visible through the skin and is a common site for drawing blood.
What does the dorsal digital vein drain to?
What does the dorsal arch drain to?
Dorsal pedal vein
What does the dorsal pedal drain to?
Anterior tibial vein
What does the plantar digital drain to?
Plantar veinous arch
What does the plantar veinous arch drain to?
Lateral or Medial plantar veins
What do the lateral and medial plantar veins drain to?
Posterior tibial vein
What do the anterior and posterior tibial veins drain to?
What great vein drains the leg?
Where does the great saphenous vein drain?
femoral vein, just distal to the inguinal ligament
What is the longest vein in the body?
Where does it run?
Great saphenous vein
dorsal foot to upper thigh
How does blood drain from the anterior tibial vein to the heart?
Anterior tibial to popliteal to femoral to external iliac to common iliac to inferior vena cava
