circulatory system
The term 'sistema circulatorio' in Spanish translates to 'circulatory system' in English. The circulatory system is a vital part of the human body, which is responsible for the transportation of nutrients, oxygen, and hormones to and from the cells throughout the body. It consists of the heart, blood vessels, and the approximately 5 liters of blood that the blood vessels transport. Proper functioning of the circulatory system is crucial for survival.
