Heart's Anatomy Research Paper

Inside our body there is a powerful muscular pump, which is known as the one of the main organs in the human body. This hollow, cone shaped, pump lies slightly left within the center of the chest called our heart. The heart is made up of different structures and actions in order for it to work, combined with a network of blood vessels form what we know as the cardiovascular system.

If the heart beats too fast, too slow or irregularly, it may not be able to pump enough blood to all of the body.

The heart is a very strong muscle that has one major job. The heart’s job is to pump blood throughout the entire body. The heart is made up of 4 chambers, and 4 valves. There is the right and left atrium, and a right and left ventricle. The atriums are the superior chambers, and the ventricles are inferior chambers. The left ventricle is the most important, because that is where the blood travels through to go to the aorta, and eventually the rest of the body (Taylor 2015).

Blood then travels out toward the lungs for oxygenation via the pulmonary artery and returns to the heart through the pulmonary veins entering the left atrium. It is pumped through the mitral valve into the left ventricle to exit the aortic valve to the circulation via the aorta. The questions asked in the lab packet directly related to the anatomy and physiology of the heart which allowed to understand how the heart works as a

5. Conduction, pp.1099-1103. Conduction system of the heart. Specialized cardiac muscle cells in the wall of the heart rapidly conduct an electrical impulse throughout the myocardium. The signal is initiated by the SA node (pacemaker) and spreads to the rest of the atrial myocardium and to the AV node. The AV node then initiates a signal that is conducted throught the ventricular myocardium by way of the AV bundle (of His) and Purkinje fibers.

The atria and ventricles are separated by valves known as the AV valves. The purpose of these valves is to prevent blood from flowing in the wrong direction. Following the movement of blood from the atrium, into the ventricle, the AV valve snaps shut which causes the first heart sound of the heart beat. The beat is caused by the closing of two other valves.

The central organ of the Cardiovascular System is the Heart, the muscular organ pumps blood through an intricate network of Blood Vessels to all parts of the body. The heart sends blood around the body. The blood provides the body with the oxygen and nutrients it needs. It also carries

The human heart is a found within the chest cavity surrounded by the lungs. Roughly the size of a fist, the heart is a tenacious automated muscular unit that directs oxygenated blood through a sequence of four chambers. Inside these chambers there are four corresponding valves which permit blood to travel in the forward direction. On any given day the heart beats 100,000, and is capable of perfusing blood throughout the bodies’ 60,000 mile system of blood vessels (Christensen & Kockrow, 2011).

When you walk up the stairs, go for a run, or go through different emotions like happiness and anxiety, your heart will work harder. A runner would have increased heart rate to get rid of the excess CO2 buildup in the blood, and replenish tissues with nutrients and oxygen. When someone meditates, they calm their bodies and minds down and slow down the heart rate of the heart. The heart is a four-chambered organ. It contains two atria and two ventricles, both which are located in the left and right parts of the heart. When blood travels from the tissues to the heart, it goes through the vena cava vein and into the heart. The blood travels from the rights atrium to the right ventricle. Once the ventricle fills up with blood, the papillary muscle help

The right atria inter-nodal tracks and Bachmann's bundle conduct the SA-nodal activation throughout the atria initiating a coordinated contraction of the atria walls. Meanwhile, the impulse reaches the AV-node, which is the only electrical connection between atria and ventricles. The AV-node introduces an effective delay, allowing the contraction of the atria to complete before ventricular contraction is initiated.

In conclusion, the human heart works in a very complex way, and as human anatomy develops over the years to have a better understanding of how the human heart works, it is very important that people have a better understanding of how it

The heart is located in the chest between the lungs behind the sternum and above the diaphragm. It is surrounded by the pericardium. Its size is about that of a fist, and its weight is about 250-300 g. Its center is located about 1.5 cm to the left of the midsagittal plane. Located above the heart are the great vessels: the superior and inferior vena cava, the pulmonary artery and vein, as well as the aorta. The aortic arch lies behind the heart. The esophagus and the spine lie further behind the heart.

An Overview of The Human Heart- Information on what the human heart is and how it functions.

Anatomy. The Heart is a four-chambered muscular organ that pumps the blood around the body. The Heart lies in the Mediastinum, within the Thoracic Cavity. The Heart lies just to the left of the midline with its Apex near the Sternum.
