platelets
False
they leak plasma
no it actually constricts. :)
capillaries
The capillaries absorb oxygen at the lungs. This occurs near the alveoli.
Substances exchanged through diffusion between blood and cells.So capillaries should be near to cells.
Cells need to be near capillaries because capillaries carry blood which in turn brings food/fuel to the cells and removes waste products.
either veins capillaries or arteries :O
oxygen out of blood, carbon dioxide into blood
A "near miss" is some event that, while it did not result in injury, illness, or damage, had the potential to do so.
Your brain recieves signals from your skin receptors that tells your brain that your temperature is too hot. You produce sweat from your sweat glands, which cools your body down. The hairs on your arms lie flat against your skin so that no hot air can be trapped there. Your capillaries that are near the surface of your skin dilate/get widen so that more blood can get to the surface and so that more heat can be lost.
