What blood vessel returns blood from the lower limbs, pelvis and perineum, and abdominal structures to the right atrium of the heart?

Veins that drain the head, neck, and upper limbs merge to form what vessels?

Vessels formed by the merging of veins draining the head, neck, and upper limbs themselves merge to form what vessel, which then drains into the right atrium of the heart?

The common carotid arteries bifurcate into what arteries?

The external carotid artery terminates by dividing into what two arteries?

The internal carotid artery ends by bifurcating into what two arteries?

What arteries arise from the subclavian arteries and travel through the transverse foramina of the cervical vertebrae, enter the skull through the foramen magnum and merge to form the basilar artery?

The basilar artery ends by splitting into what arteries?

What anastomosis of arteries lies around the sella turcica?

What small artery connects the left and right anterior cerebral arteries?

What small arteries connect the posterior cerebral arteries and the internal carotid arteries?

What veins drain the cranial cavity and extend through the transverse foramina of the cervical vertebrae?

What structures collect venous blood from within the cranial cavity and are formed by the two layers of the dura mater?

What artery emerges from the subclavian artery and supplies the mammary glands and the anterior thoracic wall?
