The Blood

Science > Biology > Human Anatomy and Physiology > Cardiovascular System > The blood, an Overview In the Cardiovascular system, the ‘‘heart’’ (cardi) pumps the blood in a ‘‘little circle’’ (circul), which travels through ‘‘little vessels’’ (vascul). In human, the transportation is done through blood circulatory system and lymphatic system. Thus two fluids move through […]
