$\large{\boxed{\underline{\underline{\bf{TO \: FIND:-}}}}}$

• The circulatory system transports nutrients and waste products, amongst other things, around the body. Is this statement True or False ?

$\large{\boxed{\underline{\underline{\bf{ANSWER:-}}}}}$

This statement is True.

$\large{\boxed{\underline{\underline{\bf{REASON:-}}}}}$

$\implies$The circulatory system is responsible for the continuous movement of all body fluids, its principal functions are to transport oxygen and nutrients to the tissues, and also to remove carbon dioxide and other metabolic waste products from the tissues. The circulatory system is also involved in temperature regulation and distribution of molecules such as hormones, etc.

$\implies$In vertebrates, the organ system responsible for the transport of substances inside the body is called circulatory system. It consists of heart, blood and lymph vessels.

$\large{\boxed{\underline{\underline{\bf{Components \: of\: circulatory \: system:-}}}}}$

$\implies$ The circulatory system has two functional components– the blood vascular system, and the lymph vascular system.

⚫ Blood vascular system :- The blood vascular system constitutes a circuit of vessels through which flow of blood is maintained by continuous pumping of the heart. The arteries carry oxygenated blood to all parts of the body (except lungs where they carry deoxygenated blood for purification) through a network of capillaries which are the main sites of exchange of substances between the tissues and blood. The deoxygenated blood then travels through veins to the heart (pulmonary veins carry oxygenated blood from the lungs).

⚫ Lymph vascular system :- The lymph vascular system is merely a passive drainage system for returning excess extravascular fluid, called lymph, to the blood vascular system.
