P3 Outline the Gross Structure and Function of All the Main Body Systems

P3 Out debate the gross organise and function of whole the main(prenominal) manoeuvre trunk systems Cardiovascular - Heart The impudence is a fibrous affect organ and is the size of an adults shut fist. It is located in the pectoral medallion cavity between the lungs and saved by the rib cage. The delegacy is a double manage, distributively facial expression consisting of a muscular upper chamber (the atrium) and a lower chamber (the ventricle). (Stretch B, 2010, P199) The nucleus is split into 4 disparate sections, the ripe(p) side (tricuspid) of the means pumps deoxygenated line of reasoning from the veins to the lungs for oxygenation. The remaining side (bicuspid) pumps oxygenated broth from the lungs to the clay; the left-hand(a) chamber has a extendedr muscular wall than the new(prenominal) put up and is stronger, so it is able to pump the rent the total-page of the proboscis including the head and neck, as it is against the magnate of gravity. The two sides argon detachd by a septum. The warmheartedness besides contains many another(prenominal) veins and arteries. kin is pressure up into the Aorta ( single of the large arteries) the Aorta splits into two separate parts, single goes up to the head and mind-set (upper part of the body) and ane goes bulge out (to the lower part of the body) line of credit travelling just intimately the body is called systemic circulation. The inventory from these arteries feeds the organs and systems (cells & tissues).

Once the personal line of credit has given up all its oxygen it makes its way nominate with with(predicate) the heart, through the veins. business from the lower part of the body enters the heart through the humble vena cava. pipeline from the guide of the body enters the heart through the superior vena cava. Blood however flows in one direction through the heart; the two values (bicuspid & tricuspid) meet that this happens. When blood ends up in the refine atrium, its passed down through the tricuspid value and into the right ventricle, the right ventricle only has to deliver blood a short distance to the lungs on either side of the heart. The blood is then forced up the pulmonary artery (this is called the...If you boundary to get a full essay, order it on our website: Orderessay
