Explain the Blood vascular system.

1.	Explain the Blood vascular system.
Answer» Heart- Special contractile blood pumping organ. Blood vessels – Tubes associated with heart into which the blood is pumped and circulated. Artery, Veins and Blood capillaries. Blood - Fluid connective tissue, consists of a fluid matrix, plasma and formed elements. Blood is a safer circulating fluid than environmental water because it is not affected by external changes like temperature variation, pollution etc. Blood contains carrier molecules (haemoglobin, haemocyanin, plasma proteins) that can transport much larger amounts of nutrients and gases than water.
