Once an antigen is recognized, your immune system can remember it the next time and protect you from getting sick again.
Answer:
Produced by the choroid plexus -T.This is the major secretion site.It is also produced in smaller quantities in the interstitial compartment.
Blocks blood toxins from brain tissue-F, that is the job of the blood brain barrier(BBB).
Supplies oxygen to the brain tissue-T.This gas is dissolved in the CSF together with CO2 for distribution among nervous tissues by the CSF
Maintains the concentration of glycine surrounding the brain-T
Found in the ventricles of the heart and brain-False,it does not reach the heart ventricles.This are occupied by blood.
Prevents concussions-T
Produces antibodies in response to antigen exposure in the brain tissue-False.These are produced by the B-cells, not by in the CSF,based on the specif antigen stimulation.
Effectively decreases the brain's weight-T It reduces the weight of the brain.This is done by the buoyancy it provided for the brain.
Compared to levels in the blood plasma, the CSF is higher in glucose-F.This is wrong, the glucose of the blood plasma is higher.But equal sodium ion,more chloride in CSF, and less protein.It s levels is a relefection of blood glucose.Although it may lag 2-4hrs in the CSF.
It prevents concussion,(T)and and the contraction of cardiac muscles propels its movement(T).

Answer:</h2>
<u>Oxygen</u> is breathed and <u>carbon dioxide</u> is expired during respiration process.
<h2>
Explanation:</h2>
In physiology, respiration is the development of oxygen from the outside condition to the cells inside tissues, and the emission of carbon dioxide to the outer environment.
The physiological meaning of respiration varies from the biochemical definition, which alludes to a metabolic procedure by which a creature acquires vitality (as ATP and NADPH) by oxidizing supplements and discharging waste items.
Cell respiration occurs in individual cells of life form, while physiologic respiration concerns dissemination and transport of metabolic products between the living being and the outer condition.
