The right and left coronary arteries enter the top of the heart from the aorta.
It enters the arteries.
The vein and or arteries have a very think layer of skin and prevent the "substances" from leaving.
The semi permeable membrane is called the blood brain barrier. It allows smaller molecules such as oxygen to enter the brain, and also protects the brain by preventing larger molecules such as toxins to enter.
