Nutrients and waste products from the body are transported to and from tissues by which system?

The circulatory system is responsible for the transportation of nutrients and waste products to and from tissues throughout the body. This system includes the heart, blood vessels, and blood, and it plays a crucial role in maintaining homeostasis.

Nutrients absorbed from food are carried by the blood from the digestive tract to various tissues where they are utilized for energy, growth, and repair. In parallel, waste products produced by cellular metabolism, such as carbon dioxide and urea, are transported from the tissues to organs like the lungs and kidneys, where they can be expelled from the body. This constant flow facilitates the exchange necessary for cellular functions and overall health.

In contrast, the respiratory system primarily manages the exchange of gases (oxygen and carbon dioxide) between the body and the environment, rather than transporting nutrients or waste across tissues. The digestive system focuses on the breakdown and absorption of food rather than the distribution of nutrients and wastes throughout the body. The endocrine system primarily regulates bodily functions through hormone release but does not facilitate the transport of nutrients and waste products as the circulatory system does.
