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.

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).

What is digestion and how does it work
slamgirl [31]

Answer:

Digestion is the breakdown of large insoluble food molecules into small water-soluble food molecules so that they can be absorbed into the watery blood plasma. In certain organisms, these smaller substances are absorbed through the small intestine into the blood stream.

Explanation:

Digestion works by moving food through the GI tract. Digestion begins in the mouth with chewing and ends in the small intestine. As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules. The body then absorbs these smaller molecules through the walls of the small intestine into the bloodstream, which delivers them to the rest of the body. Waste products of digestion pass through the large intestine and out of the body as a solid matter called stool.
