oxygen and nutrients that have been delivered to the brain cells, as well as waste products like carbon dioxide and other byproducts of cellular metabolism. It also carries neurotransmitters and other signaling molecules that are important for brain function.
The brain is generally considered one organ, and yes blood delivers oxygen to the brain, so when the blood leaves the brain, it is oxygen depleted. This oxygen fuels the brain through respiration, which gives it the energy to keep you alive and constantly keep your bodily functions in line. There is a blood brain barrier though, so blood never actually enters the brain and oxygen diffuses over this barrier.
Blood contains the most water, comprising about 90% of its composition. The brain is also largely composed of water, with around 75% of its weight being water. In contrast, the skeleton is made up of bone, which contains only about 20% water. Therefore, blood has the highest water content, followed by the brain, and then the skeleton.
You just broke my brain cells
The cranial cavity contains the brain, pineal and hypophysis cerebri, parts of the cranial and spinal nerves, blood vessels, meninges and cerebrospinal fluid.
Brain of Blood was created in 1972.
Your Brain contains more water than your blood and your skeleton!

Yes, lymph contains white blood cells, as well as salts, water, and large molecules
Some can, not all. If the tumor contains cells that can it will metastasize.

the blood contains proteins as tissue is a plasmid for h2O for photsynethis in the carribean weather for red blood cells and thrush in the head of the brain plamid content.

After a meal the brain delivers more blood to the digestive system, leaving the rest of the body (including the muscles) with less blood. Low blood pressure makes you feel tired
The brain needs so much blood because it needs a constant supply of it to keep up with the neurons metabolic demands. 20 percent of the blood that comes from the heart is pumped directly to the brain.
It gets into the brain quickly because the brain gets a rich blood supply and because alcohol is able to diffuse across the blood-brian barrier easily due to being not strongly polar.
The brain contains no muscles. It is made up almost entirely of nerve tissues with a bit of connective tissue and certainly the blood vessels and lymphatic drains.
