Name four things that are transported by the circulatory system.

Oxygen: The circulatory system transports oxygen from the lungs to the rest of the body's cells.

Nutrients: Nutrients from the food we eat, like glucose and amino acids, are absorbed in the digestive system and then transported by the circulatory system to cells throughout the body.

Hormones: The circulatory system also transports hormones, which are chemical messengers that regulate bodily functions. These hormones are produced by various glands in the body and then sent into the bloodstream to reach target cells.

Waste Products: Finally, the circulatory system helps to remove waste products like carbon dioxide and urea. These waste products are transported to the lungs and kidneys, respectively, to be excreted from the body.
