Verified step by step guidance

Begin by identifying the primary function of each organ system listed in the problem. The digestive system is responsible for breaking down food and absorbing nutrients. The respiratory system is involved in gas exchange, primarily oxygen and carbon dioxide. The nervous system is responsible for transmitting signals throughout the body.

Next, consider the circulatory system, which is not listed among the options but is mentioned as the correct answer. The circulatory system, also known as the cardiovascular system, is responsible for transporting nutrients, gases, and waste products throughout the body.

Understand the components of the circulatory system: it includes the heart, blood vessels (arteries, veins, and capillaries), and blood. The heart pumps blood through the vessels, allowing for the distribution of essential substances.

Recognize the role of blood in the circulatory system. Blood carries oxygen from the lungs to the tissues and carbon dioxide from the tissues to the lungs. It also transports nutrients absorbed from the digestive system to cells and carries waste products to the kidneys for excretion.

Conclude that the circulatory system is the organ system primarily responsible for the transportation of nutrients, gases, and waste products throughout the body, as it integrates the functions of other systems to maintain homeostasis.
