However, in all of these configurations in which a diagram is provided on the club or a raised portion of the club is provided which is similar to the ball, the eye of the golfer is naturally attracted towards the center of the representation instead of towards the point of impact, i.e., towards the location where the player will hit the ball with the head of the putter. In vertebrate animals, the heart is a hollow muscular organ having four pumping chambers as seen in FIG. 1: the left and right atria and the left and right ventricles, each provided with its own one-way valve. The natural heart valves are identified as the aortic, mitral (or bicuspid), tricuspid, and pulmonary, and are each mounted in an annulus comprising dense fibrous rings attached either directly or indirectly to the atrial and ventricular muscle fibers. Each annulus defines a flow orifice.
The atria are the blood-receiving chambers, which pump blood into the ventricles. The ventricles are the blood-discharging chambers. A wall composed of fibrous and muscular parts, called the interatrial septum separates the right and left atriums (see FIGS. 2, 3 and 4). The fibrous interatrial septum is a materially stronger tissue structure compared to the more friable muscle tissue of the heart. An anatomic landmark on the interatrial septum is an oval, thumbprint sized depression called the oval fossa, or fossa ovalis (shown in FIG. 4).
The synchronous pumping actions of the left and right sides of the heart constitute the cardiac cycle. The cycle begins with a period of ventricular relaxation, called ventricular diastole. The cycle ends with a period of ventricular contraction, called ventricular systole. The four valves (see FIGS. 2 and 3) ensure that blood does not flow in the wrong direction during the cardiac cycle; that is, to ensure that the blood does not back flow from the ventricles into the corresponding atria, or back flow from the arteries into the corresponding ventricles. The mitral valve is between the left atrium and the left ventricle, the tricuspid valve

 However, in all of these configuration in which a diagram is provided on the club or a raise portion of the clubhouse is provide which is similar to the ball, the eye of the golfer is naturally attracted towards the center of the theatrical performance instead of towards the point of impact, i.e., towards the localization where the player will hit the musket ball with the head of the putter. In vertebrate animal, the heart is a empty muscular organ having four pumping chambers as see in FIG. 1: the left and right atria and the left and right ventricle, each provided with its own one - way valve. The natural heart valves are identified as the aortic, mitral (or bicuspid), tricuspid, and pulmonary, and are each mounted in an ring consist dense fibrous ring attach either directly or indirectly to the atrial and ventricular muscle fibers. Each ring defines a menstruation orifice. 
 The atria are the blood - welcome chambers, which pump blood into the ventricles. The ventricles are the blood - discharging chamber. A wall composed of fibrous and muscular parts, called the interatrial septum branch the right and left atriums (see FIGS. 2, 3 and 4). The fibrous interatrial septum is a materially strong tissue structure compared to the more friable muscleman tissue of the heart. An anatomic landmark on the interatrial septum is an oval, thumbprint sized depression called the ellipse fossa, or fossa ovalis (shown in FIG. 4). 
 The synchronous pumping actions of the left and right side of the heart appoint the cardiac cycle. The hertz begins with a menstruation of ventricular relaxation, called ventricular diastole. The cycle ends with a period of ventricular compression, called ventricular systole. The four valves (see FIGS. 2 and 3) see that blood does not flow in the wrong direction during the cardiac cycle; that is, to guarantee that the blood does not back stream from the ventricles into the corresponding atria, or back flow from the arteries into the corresponding ventricles. The mitral valve is between the leftover atrium and the left ventricle, the tricuspid valve
