Circulatory System

Jake's circulatory system comprises of the vessels of blood and heart, veins, capillaries, and arteries. Beginning from the right sided ventricle, the passage of blood is from the Jake's pulmonary veins that bring the blood flow to Jake's lungs. There are small branches of pulmonary arteries, until the vessels of blood are extremely little and slim walled, called the capillaries. These slimmed wall capillaries let the carbon dioxide (CO2) and oxygen to pass. The oxygen bypasses from the sacs of air, the alveoli, in lungs, in the capillaries of blood and the CO2 flow from the alveoli capillaries. The gas just travels down a gradient of concentration. As the oxygen concentration is high in the alveoli in the air, oxygen passes from the capillary, in the blood. The CO2 concentration is more in the blood, as a result the CO2 flow into alveoli. The collection of blood is made into the pulmonary vein that merges with different veins to be gradually bigger and empty in the left-sided atrium by 4 big veins (Hauptmann, Mohan, Doody, Linet, & Mabuchi, 2003).

Then, blood goes by the left ventricle that pushes blood in the main blood vessel, the aorta. Also, the systemic arteries branched into increasingly smaller blood vessels and take the blood to the remaining body organs. These blood vessels eventually subdivided into capillaries of thin wall as well in the different organs. And again, the CO2 and oxygen can immediately bypass by the capillaries' thin walls, apart from traveling of oxygen from the blood vessel in the tissue, and CO2 passes through the capillary's tissue. Then blood gathers into vein and passes back to the heart by bigger veins. The 2 main veins are the inferior vena cava and superior vena cava that carry blood from lower and ...
