What else can I help you with?
Why does the blood leaving most organs in the brain have less oxygen than when it entered the brain?
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.
What contains the most water blood brain or skeleton?
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.
explain how substances are exchanged between the blood entering the nephron and the filtrate leaving the collecting duct?
You just broke my brain cells
Cranial cavity contains what?
The cranial cavity contains the brain, pineal and hypophysis cerebri, parts of the cranial and spinal nerves, blood vessels, meninges and cerebrospinal fluid.
When was Brain of Blood created?

Which contains more water your blood brain or your skeleton?
Your Brain contains more water than your blood and your skeleton!

How does blood differ from tissue fluid?
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.
Cranial cavity contains what?
The cranial cavity contains the brain, pineal and hypophysis cerebri, parts of the cranial and spinal nerves, blood vessels, meninges and cerebrospinal fluid.
Why causes you to feel tired after a meal?
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
Why does the brain need a continuous supply of blood and oxygen?
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.
Why is alcohol so quick to find its way 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.
Do muscles in your brain help you think?
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.
