Circulatory
The digestive system digests the food, then the nutrients are circulated through the bloodstream.
The circulatory system transports food oxygen and waste from the rest.The digestive system breaks down food into nutrients and puts them in the blood. The lungs (respiratory system) take oxygen from the air and puts them in the blood, and takes carbon-dioxide from the blood and puts it in the air. The kidneys (excretory system) take the chemical waste out of the blood and excrete it as urine.So blood is the common factor here, and it is the veins, arteries, and the heart that circulates blood, nutrients ("food"), oxygen, and chemical waste throughout the body. The veins, arteries, and heart combined are the circulatory system.
The circulatory system doesn't store anything. It only acts a transporters who transports materials to all parts of the body.
The circulatory system is responsible for transporting nutrients, oxygen, and other essential molecules to the cells in the body. This system includes the heart, blood vessels, and blood that circulate throughout the body to deliver these necessary substances.
The circulatory system (blood and vessels) transports oxygen and nutrients around the body. The heart furnishes the power to move the blood.
just buy it. all the others have bad stuff on them.
The circulatory system, comprising the heart, blood vessels, and blood, is responsible for transporting nutrients, oxygen, and waste products to and from all cells in the body. The heart pumps oxygen-rich blood to the body's tissues and organs, while the blood vessels transport nutrients and oxygen to the cells and carry waste products away for elimination.
