Bone is the major storage site for calcium ions. What transport mechanism would be used to transport additional calcium ions from the bloodstream into the bone and why would only this method of transport work?

i think the answer is gold im not entirely sure

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.

ok yes, but what is the question? as soon as you ask the actual question i will answer it. : )
