Describe how the thickness of the aorta compares to the other great vessels. proveive a reason for this differece.

The aorta is the main artery of the body which makes sense why it would be  thicker than the other vessels in the human body. The aorta is of vital importance because it is responsible for distributing oxygenated blood to all parts of the body.

Atp is is our little "pocket" of energy. of course, if you have too little, then it means you have too little energy, and you'll pass out. the way to not have enough, is to have no energy sources (glucose, fats, proteins). you can't have too many atp molecules. cycles like the krebs cycle produce it, but if you have too much of any substrate (or too little for that matter), the cycle stops and atp is no longer made (it stops until substrate levels are such that the process can go on). in any case, this is unlikely since atp is constantly hydrolyzed and remade, even while you're asleep. you won't have too much. if you have zero, you are dead or dying.
