Answer 1

The correct answer is option a. internal carotid and vertebral; jugular

Step-by-step explanation:

Hello!

Let's solve this!

The internal and external carotid arteries carry blood between the head and neck, the difference is that one carries blood to the brain and the other to other parts of the head.

The internal carotid artery is the one that carries blood to the brain. Blood moves away from the brain through the jugular vein.

We can conclude that the correct answer is option a. internal carotid and vertebral; jugular

Answer 2

Blood flows to the brain through the internal carotid and vertebral arteries and away from the brain through the internal jugular vein. The internal carotid artery supplies the brain, while the external carotid nourishes other portions of the head, such as the face, skull, scalp and the meninges. The vertebral arteries provide supply to the upper spinal cord, brainstem, cerebellum, and the posterior part of the brain.
