Have you ever wondered how all the residents of the city get their water? Perhaps you've noticed the giant water towers on the outer edges of a city skyline. Individuals and homes miles away only have to turn on a faucet handle for the water to flow out of pipes and into their kitchen sink. The simplicity of that system should be near and dear to all of our hearts, but figuratively and literally. The water tower system is known as modern plumbing bodies. Method is called the systemic circulation system. Modern plumbing, like our hearts, is a circulation system with a pump that depends on pressure to maintain that pressure. It requires three elements to function a container fluid and, of course, the pump in the body. Your arteries and veins make up the container. Blood is fluid. On the heart is the pump. Thes elements are a three legged stool. Any failure or disruption of one of those on the stool tips over. You spent an earlier chapter studying the body's fluid, a k a blood. So hopefully you're pretty well versed on its components. Plasma and formed elements red and white blood cells. But did you know that the body contains 4.5 to 6 liters of blood. Need a visualization of that quantity? Picture 1.5 gallons of milk. That amount of fluid is important. The body can handle some loss. Trying to run your body without blood is like trying to run your car without oil and gas. At the same time, you're heading for a crash and burn soon. L Let's talk about the bodies. Container the arteries and veins, arteries and veins or the major distribution highways of your body because your blood is carrying oxygen nutrients, waste hormones, heat and other resource is cells of your body depend on minute by minute highway system has to be extensive and efficient. Oxygenated blood is carried by the arteries and travels away from the heart. Veins carry de oxygenated blood to the heart, just like the road system has interstates with exits, small streets and driveways. Next to homes and businesses, the body has its own system. Instead of smaller and smaller roads, the bodies major interstates. Air arteries lead to smaller arterials, which need to permissible Capital Aires, where oxygen and nutrients leave the blood and are exchanged in the body's tissues. Carbon dioxide and metabolic wastes leave the tissues and re enter the blood to be brought back to the heart and lungs to be re oxygenated. Pressure is partially maintained by keeping a consistent amount of fluid in the container. So how does the body get all of the nutrients oxygen and carbon dioxide exchanged outside of the container without losing too much? Thankfully, the body has a backup piping system that collects the fluid that leaks out during the exchange. This is called the Limp System and also plays a role in your body's immunity without discussion is for a later chapter. Last but not least, is the heart the bodies pump, which is responsible for moving and distributing blood from your head to your toes. Heart is divided into two sides, right and left by the inter ventricular septum. The sides are further divided into top and bottom chambers, thes chambers air called the right and left atria and right and left ventricles. The heart collects de oxygenated blood from the body through the superior and inferior vena Kaveh. This blood drains into the right atrium. Three top chambers of the heart contract and the collected blood is pushed down into the right ventricle through the try custody valve. Then the bottom chambers of the heart contract on the trike husband valve slams shut, resulting in the love sound that could be heard through a stethoscope. Blood is pushed from the right ventricle through the pulmonary semi lunar vows and travels to the lungs via the pulmonary artery where it circulates, exchanging carbon dioxide for fresh oxygen. The oxygenated blood returns to the heart through the pulmonary veins, which drain into the left atrium through the by husband or my troll again. The top chambers or atria of the heart contract, pulmonary and aortic semi lunar valve slams shut, resulting in the dub sound as the blood is pushed into the ventricles ventricles contract again, pushing the oxygenated blood into the aorta through the aortic pulmonary valves where it circulates to the rest of the body. In the real world, the failure of plumbing and the body systemic circulation system have consequences. If the pressure drops in your homes, plumbing, the hot shower spray may become more of a drizzle. In that case, you call a plumber looks for a leak or a broken pipe or faulty pump. When a person's blood pressure changes to be too high or too low, paramedics, nurses and doctors rapidly searched for a wood internal bleeding or a heart blockage. Most of the time, our body is capable of maintaining its own plumbing through a system of hormonal checks and balances. However, when these checks and balances fail and help is not received, the result is flat mine.
