chamber) pumps the blood away from the heart. The atria and ventricles chambers are separated by four main valves called the atrioventricular (two valves)‚ pulmonary‚ and aortic valves. These valves help create the heart sounds often referred to as “Lub” and ‘Dub”. Thus‚ the Lub sound is the closing of the atrioventricular valve‚ and the Dub sound is the closing of the pulmonary and aortic valve. In this lab‚ we became familiar with the functions of the heart. We also determined

to the left ventricle to get pumped to the muscles so they can transport the oxygen to them. Valves The four main valves in the heart are: The two atrioventricular (AV) valves‚ the mitral valve‚ and the tricuspid valve‚ which are between the upper atria and the lower ventricles. The two semilunar valves‚ the aortic valve and the pulmonary valve‚ which are in the arteries leaving the heart. The valves allow the blood to flow in only one direction. They open and close depending on the blood

Some conditions that have been proven factors in leading to heart failure include past heart attacks‚ high blood pressure‚ abnormal heart valves‚ heart muscle disease‚ heart defects present at birth‚ severe lung disease‚ and sleep apnea.

The word ’fossil’ has been derived from the Latin word ’Fossilium’‚ which literally means anything dug out of the earth’. These are recognisable remains of once-living plants or animals‚ most of which have been extinct for many thousands of years. They were preserved in sediments‚ rocks and other materials such as ice‚ tar‚ amber etc. prior to historic times. Thus‚ the remnants of plants or animals of the past geologic ages preserved in the rocks of the earth’s crust by natural processes are known
