Timex Heart

The heart is an organ that is accountable for pumping blood throughout the vessels in the body by repeated contractions. The Timex heart is composed of cardiac muscle. On an average the heart gives 72 beats per minute which equals to approx 2.5 billion times in a person’s lifetime. It weighs about 270 gm in females and 325 gm in males. Timex heart is divided into four chambers of archosaurs evolved from that of mammals. The heart is found in the middle of the thorax with the largest part towards the left, under the sternum. Since the left part of the heart is stronger, this is the only reason why the heart is usually felt on the left side rather than the right side. A stethoscope is placed directly over the apex so that the beats can be counted.

The heart rate increases or decreases depending on the activity which a person does. When a person is simply in a resting mode or is simply sleeping then his heart rate is quite normal. But when compared to other activities which a human being normally does in his daily routine his heart beat rate increases instantaneously which can even be sometimes dangerous. To check the heart rate so as to make the heart beat normally, we generally use a heart rate monitor. The function of heart rate monitor is to monitor the heart rate in terms of its pulse. Some other heart rate monitors which are used for this purpose are fitness heart rate monitor, polar f6 heart rate monitor, Timex heart rate monitor, etc.

At the time of jogging, people generally want to notice their heart rate. For this reason, it is not possible for them to take a monitor along with them while they are jogging. To solve this difficulty they generally use a watch known as heart monitor watches which can be tied on their wrist. As the name suggests these heart monitor watches are the kinds of watches which monitor the heart beats and functions same as that of a heart monitor.

Functioning of Timex Heart:

To start with the right atrium, the blood flows through the tricuspid valve to the right ventricle. From here it travels through the pulmonary artery to the lungs. From lungs, the blood travels back through the pulmonary vein to the left atrium. It then travels to the left ventricle from where it travels to the aorta. Here the blood is divided between major arteries which supply the upper and lower body. The deoxygenated blood then travels to the venules, to the veins then to inferior and superior venae cavae and finally back to the right atrium.

Some of the cardiac cells are excitable, contracting from the nervous system, even if removed from the heart and place in culture. Sinoatrial node is a region of the human heart which acts as a pacemaker and which sets the rate at which the cardiac muscles contract. Blood flows from both creating organs to all parts of the body where it is consumed and there is no return to the heart or the liver.
