Cardiovascular system Cardiovascular eyeter includes heart and blood vesele. Hearst pumps blood into the blood vessels. Blond vessels circulate the blood throughout the body. Bland transports nutriente and oxygen to the tissues and removes carbon dioxide and waste products from the tissues. Heart- Heart is a muscular organ that purps blood throughout the circulatory eyeten It is situates in between twa lunge in the rediasteniors. It is rade up of four charbers, two atria and two ventricles. The musculature of ventriclel is thicker than that of atria. Force of contraction of heat depend upon the ruscles. Right side of heart:- Right side of heart has two charbers, right atrius and right ventrick. Right athivers is a thin walled and low pressure chambes. It has got a pacemaker krown as sinoaterial node that produces cardiac impules and antrioventricular nude that conducts the impulses to the ventricles. Right atrius recieves venous bloed via two large veine :- 1. Superior vena cava 2. Inferior vena cava. Right triwr communicates with right ventricle through tricuspid valve Wall of right ventricle is thick. Venous blood from the right atrium enters the right Ventricles through this valve. From the right ventrick, pudronary artery risco It carries the venous blood from right ventricle to longs. In the wings the desxygenated blood is oxygenated. Left side of heart left side of the heart has two charbers, left atriure and left ventricks Lept atrium is a thin walled and low pressure porter. It recieves oxygenatel blood from the lungs through pulmonary wine. This is the only expectation in the boty, whore artery carries venous bloed and vein carriers the arterial blos. Blood from left atriure enters the left ventricle through mitral vake. Wall of the oft ventricle is very thick left ventricle purp's the arterial blood to dinherent parte of the body through systeric corta.
