Circulatory systems
Circulatory systems move blood around an organism’s body. They are important for continued life of the cells, tissues and entire body of any organism. There are two types of circulatory systems. Open and Closed.
An elephant is one of the largest land mammals on earth and therefor it has a large body with a large circulatory system. The circulatory system pumps blood through arteries, veins and capillaries. The blood transported around the body reaches organs to nourish cells. In return waste products are diffused into the blood so that it can be carried away and disposed of. Vital organs that assist in the circulatory system include the liver, kidneys and heart. As the blood passes through the liver and kidneys, wastes are removed and then the blood travels to the lungs where a fresh supply of oxygen is given. This process repeats itself over and over. The heart is known as a four-chambered heart. The chambers consist of two atria and two ventricles. The two atria are liable for receiving blood from veins connected to the heart. The blood is then pumped into the ventricles after a contraction from the atria. Once the blood is in the ventricles, the ventricles push the blood away from the heart, strong enough so that the blood can go around the body and return to the heart. The blood can only flow in one direction and valves, which are overlapping layers of tissue, prevent the blood from changing direction.
The Praying Mantis, an insect classified as an invertebrate, has an open circulatory system. This circulatory system is common among molluscs and arthropods. The circulatory system works by pumping a substance known as hemolymph around the body so that it directly supplies organs and tissues with the needed amount, and transports nutrients and wastes around. The blood that enters the body is diffused between cells rather than in a particular blood vein or arteries.
