 * __How can the Cardiovascular System be improved?__**

The Cardiovascular System could be improved by directly attaching **capillaries** to muscles or even inducing the capillaries to have their own specific muscles so that the blood circulation is more fluent. Smooth muscle tissue in the **tunica media** of veins, that contracts rthymically, as in **peristalsis**, might help blood return to the heart. Another improvement might be having the heart itself contain extra **stem cells** to repair any damage that could potentially be incurred in the future, such as damage from heart attacks. In addition, the two extra kidneys the fetus develops should remain after birth, so they can be used as replacements should something happen to the original two kidneys. This guarantees that a transplantation can be provided for and eliminates the possibility of rejection. -GY

The introduction of extra **"pumps"** into the circulatory system could serve to circulate blood more efficiently back to the heart. Currently, blood in the veins relies on muscle contractions and low pressure systems created by the respiratory system to circulate back to the heart. Strengthening either the **atria** to produce more of a suction force on the returning blood, or the additions of extra pumps placed strategically in the circulatory system could completely eliminate the need for returning blood to rely on muscle contractions and the respiratory system. While the solution of adding more “pumps” to the body may seem like a waste of energy, these additional pumps need not be as extreme as the cardiac muscles. Gentle contractions of several small pumps would be very effective, as the only place they need to send the blood is back to the heart. This system might have the additional benefit of being able to extend the time medical personnel have to restart the heart by producing a minor circulation even when the main heart is disfunctional.
