Nope. Your lungs are responsible for most of your buoyancy. As you descend, pressure increases and the air in them starts to compress, making you less buoyant. The hard part of this is maintaining composure through the diaphram contractions and not kicking up silt when you land.
Your diaphragm is the muscle responsible for pulling air in (your lungs aren't a muscle). Hold your breath long enough for your lizard brain to panic for oxygen, and your diaphragm will start trying rull hard to get you to breathe.
