How Are The Urinary And Cardiovascular Systems Connected? The Cardiovascular system is the center point of the body and it is connected with all the other systems. Its main job is to supply oxygenated blood that keeps every organ alive. Blood travels through the arteries and the veins in our body. One of its important destination is the Urinary system, the Kidneys.
The kidneys are the most important excretory organs. Blood gets to the kidney through the renal arteries that branches off from the abdominal aorta, which is connected to the left ventricle of the heart. Renal arteries branches into smaller arteries to the Nephron unit, the urine making structure of the kidney. While the blood travels through the nephron, there are many things that is done to the blood. For instance, blood pH is regulated by controlling the excretion of hydrogen ions. Also, blood is regulated to lower down the pressure in the vessels by inhibiting the secretion of renin. Moreover, blood pressure is lowered by regulating the volume in the nephron. The nephron then determines the amount of water excreted out of the system. Functioning urinary system is very important to the heart to do its job. Without its help, the heart would be working extra load or would not function at all.
Finally, blood takes off from the Loop of Henle to the renal vein that connects to the inferior vena cava and back to the heart. The cycle repeats just like everything else in our body and they all start from the greatest organ of all, the heart.
