Question

Quizplus · Accepted Answer

The choroid plexus is a network of blood vessels in the ventricles of the brain that secretes cerebrospinal fluid (CSF). CSF is formed here through a process of filtration and secretion by the specialized epithelial cells of the choroid plexus. Therefore, choice A is the correct answer. Choice B is incorrect because the internal carotid artery is a separate structure that supplies blood to the brain, while the choroid plexus is responsible for producing CSF. Choice C is also incorrect because the subarachnoid space is where CSF circulates and is absorbed, not drained, and the choroid plexus is not directly involved in this process.
