1. Explain the function of the heart, and the structure of the arteries veins and capillaries
The heart is a key muscular organ, and is controlled by the autonomic nervous system. It transports blood to the body’s tissues via the circulatory system; blood provides the body with oxygen, nutrients and also assists in the removal of carbon dioxide and metabolic wastes, hormones are transported throughout the body by plasma. Arteries, arterioles, veins, capillaries and valves, are the blood vessels which are responsible for transporting the blood throughout the body.
The arteries are thick walled muscular and elastic, three layered hollow tubes the thickness is needed to cope better with the pressure of blood flowing through the lumen of

    The Pintails heart is like a mammals consisting of four chambers, two ventricles and two atria. The left ventricle pumps blood to all major organs in the body and throughout the rest, only excluding the lungs. This causes the left ventricle to be larger and more muscular. The lungs are fed blood from the right ventricle, which is the only the only function of that ventricle. The oxygenated blood coming from the lungs is fully separated from the oxygenated blood coming from other parts of the body.

    If a person does not have a cardiovascular system that is in good working order, it can be a fatal situation. Along with pumping blood to the body, the cardiovascular system also brings oxygen and nutrients to all of the different organs and tissues within the body. As our blood makes its circuit journey from the heart to the extremities and then back to the heart, waste is removed from the cells as well. For the cardiovascular system to function at an optimal level, it needs to be healthy and fit.

    Harvey William Harvey’s seminal work “On the Motion on the Heart and Blood in Animals” initiated modern medicine. Harvey’s arguments were detailed readily verifiable and though they did endure a fair bit of criticism when released, in most areas, they were accepted within his lifetime. Once his simple notion of the circulation of blood was carefully described others were able to see and understand its validity themselves. I will argue that William Harvey’s theory which used inductive reasoning to show, with experiments, how blood flowed from veins to arteries through the heart and deduced the existence of capillaries to return blood from arteries to veins. One of the main understandings of the day, proposed by Galen of Pergamon nearly 1500 years earlier, was that blood was a resource that was produced in the liver and consumed in the tissues and the brain.
