(c) Capillaries

(d) Bones

Best Answer


Arteries carry oxygen-rich blood towards body organs, in their may they divide to form smaller-vessels. On reaching the tissues, they divide again to form extremely thin tubes valled capillaries, so that oxygen can be easily taken up by tissues. When these capillaries leave the tissues they take the carbon-di-oxide rich blood of tissues, and join to form veins. These veins take this blood to heart. Thus, capillaries form a network to join arteries and veins.
