cAMP in the cytoplasm

Explanation:

Water-solubile hormons cannot pass through the cell membrane, so they bind to their transmembrane receptors. As a result of their binding, receptor changes its shape (conformational change) and a signal cascade in the cytoplasm begins. Signal cascade includes the activation of primary and secondary messengers. Camp is a molecule often generated as a second messenger with the roleto amplify the signal in response to hormone binding.

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.
