What system transports nutrients and oxygen to tissues and removes waste products?

The circulatory system is responsible for the transportation of nutrients and oxygen to tissues throughout the body while also facilitating the removal of waste products, such as carbon dioxide and metabolic byproducts. This system comprises the heart, blood vessels, and blood itself, working together to ensure that oxygenated blood travels from the heart to various tissues and organs, delivering essential nutrients required for cellular function. Additionally, the circulatory system collects waste materials from the tissues and transports them to the kidneys, lungs, and other organs for excretion or further processing, thereby maintaining homeostasis and supporting life.

In contrast, the nervous system primarily governs communication between different parts of the body through electrical signals and is integral to reflexes and voluntary movement. The endocrine system, while involved in hormone regulation and signaling, does not directly transport nutrients or gases but rather influences bodily functions through chemical messengers. The renal system focuses on filtering blood to remove waste and regulate fluid balance, but it does not transport nutrients and oxygen to tissues. Hence, the circulatory system stands out as the correct answer, as it fulfills the specific functions of nutrient and oxygen delivery and waste removal.
