Q

Major veins of systemic circulation

image

A
2
Q

Superior Vena Cava

A

receives systemic blood from all body regions superior to the diaphragm excluding the heart wall.

Arises from the union of the left and right brachiocephalic veins

joins the right atrium

3
Q

Inferior Vena Cava

A
  • Widest blood vessel in the body
  • ascends along the posterior wall of abdominal cavity
  • returns blood to the heart from all body regions inferior to the diaphragm
  • begins at the union of the two common iliac veins at L5 vertebrae
  • Joins right atrium
4
Q

Dural Sinuses

A
  • Most veins of brain drain into this
  • Form an interconnected series of channels in the skull
  • lie between the two layers of cranial dura mater
5
Q

Superior and Inferior Sagittal SInuses

A
  • Lie in the falx cerebri between the cerebral hemispheres.

Q

Veinous drainage of head neck and brain

7
Q

Internal jugular veins

A
  • Drain almost all of the blood from the brain
  • Descends through the neck deep to the sternocleidomastoid muscle
  • Receives blood from branches of the facial and superficial temporal veins
  • Joins the subclavian vein to form brachiocephalic vein
  • Jugulum means “throat just above clavicle”

Q

Foramen Ovale in fetal circuit

A
  • slightly less than half the blood entering the fetal heart is shunted from from the right atrium (pulmonary circuit) to the left atrium (systemic circuit) through this hole in the interatrial septum
20
Q

Ductus Arteriosus in fetal circuit

A
  • A wide arterial shunt in the pulmonary trunk
  • Most of blood from pulmonary circuit shunted here
  • Carries blood from the most cranial part of the trunk to the adjacent aortic arch so only a small amount of blood reaches lungs
