Which organ system controls metabolism of our body by releasing hormones? Cardiovascular system Endocrine system Respiratory system Lymphatic System

The organ system that controls metabolism in our body by releasing hormones is the Endocrine system.

Explanation:

The endocrine system consists of glands that produce and release hormones directly into the bloodstream. These hormones act as messengers that regulate various physiological processes, including metabolism, growth and development, tissue function, sexual function, reproduction, sleep, and mood.

Metabolism refers to the chemical reactions that occur within the body to maintain life, including the processes by which the body converts food into energy. Key hormones involved in metabolism include insulin, glucagon, thyroid hormones, and cortisol. For example, insulin, produced by the pancreas, helps regulate blood sugar levels and thus plays a critical role in how the body metabolizes carbohydrates.

In contrast, the cardiovascular system primarily circulates blood and nutrients, the respiratory system is responsible for gas exchange, and the lymphatic system is involved in immune responses and fluid balance, none of which directly control metabolism through hormonal release.

Therefore, the correct answer to the question is the Endocrine system.
