This fluid, which forms continuously from fluid filtering out of a network of brain capillaries, seeps into the brain's empty spaces, called ventricles, and eventually returns to the blood.
a. arbor vitae
b. cerebral aqueduct
c. venous blood
d. cerebrospinal fluid (csf)

d. cerebrospinal fluid (CSF)

Explanation:

Cerebrospinal fluid (CSF) is cololess, clear body fluid that is found in the brain and the spinal cord in the body. It is produced in the body by particularised ependymal cells which are present in the choroid plexuses of ventricles of brain, and are absorbed in arachnoid granulations.

CSF in the body acts as cushion or a buffer for brain which provides basic mechanical as well as immunological protection to brain inside skull.

CSF in the brain moves in single direction outwardly from the ventricles, but in multidirectional in subarachnoid space.

Hence, option D is correct

cerebrospinal fluid

Explanation:

it is the fluid which is filtered from the blood to provide cushioning to the brain and it is reabsorbed back in the blood through subarachnoid space. It provides nutrients to brain and protects it from shock or trauma

arbor vitae is the white matter inside the cerebellum

cerebral aqueduct is a part of ventricular system in which the CSF flows it connects 3rd to the fourth ventricle

venous blood is the bood in the veins

yes and no depends if she cut her ginger deep

answer: tell your parents first, and wait another couple of days. if it gets any worse, then you should call and ask. and you can always take pain meds if need be.
