engine’s major components. The components in direct contact with the combustion gases are the cylinder‚ pistons‚ valves‚ and spark plugs. A piston moves up and down within the cylinder. Pistons are cylindrical metal objects whose tops form the base of each cylinder. Air is delivered to the cylinder through the in take valves and exhaust gases leave the cylinder through exhaust valves. The spark plug creates a spark and ignites the compressed air and fuel mixture. Now that we have overviewed

CARIOVASCULAR SYSTEM Cardiovascular System BSC1011 Advanced Biology Tuesday‚ January 17‚ 2012 Cardiovascular System The heart weighs 300 grams and is shaped like a grapefruit and has two atria‚ two ventricles‚ and four valves receive blood from both venae cavae and the four pulmonary veins‚ and throw it into the aorta and pulmonary trunk. The heart pumps blood to 9 liters per day‚ making from 60 to 160 beats per minute. The heart is covered with a dense fibrous

We need a transport system to deliver oxygen‚ nutrients and other substances to all our body cells‚ and take away waste products from them.

2012). Once we are ready to leave the right atrium we go into the right AV valve (AV is atrioventricular or cuspid‚ (Thibodeau‚ Patton‚ 2008.).The AV valve stops blood from flowing backwards and every time the heart beats the valve opens and closes. The AV valve allows blood to flow into the right ventricle. But before blood goes into the right ventricle it has to travel through the tricuspid valve. The tricuspid valve along with AV and SL are all structures that prevent blood from flowing backwards

Open-heart surgery had been one of the largest life saving surgeries performed. The first successful open heart surgery was performed in 1952 by Dr. F John Lewis. He used ice to cool down the heart and slow circulation. The basis of heart surgery involves exposing the heart (open). The sternum must be sawed through to expose the heart. The heart cannot be left pumping during surgery. At first ice was used but now a heart lung machine is used. It involves hooking a tube up to the aorta. Blood goes
