The heart is the most important organ in the body aside from the brain. It provides the body with much needed blood. The heart has many functions to perform and undertake if it is to provide and support the lifeform that it is within. The major function of the heart is pumping oxygenated blood around the body in order for the body to work to its highest ability. In order for the muscles in the body to function properly, blood is needed. The heart pumps blood to all the important areas throughout the body through an artery known as the aorta (which is the main artery which leads from the body). A thick layer of muscle called the septum which separates both sides of the heart. The deoxygenated blood exits through the right ventricle of the heart …show more content…

When you exercise at a very hard rate your heart begins to beat faster as you increase the amount of exercise. As your exercise you use a lot of oxygen which makes your heart and lungs work harder and faster. The lungs work harder and become stronger during exercise and your heart works at a faster rate to pump blood throughout the body to the muscles that are being …show more content…

The right ventricles only function is to pump blood into pulmonary circulation for the lungs, while the left ventricle pumps blood throughout the whole of the of the body. Describe the structure and function of the different valves within the heart: Tricuspid valve: This is found in-between the right atrium and the right ventricle. Pulmonary valve: This is found in-between the right ventricle and the pulmonary artery. Mitral valve: This is found in-between the left atrium and the left ventricle. Aortic valve: This is found in-between the left ventricle and the aorta The left atrium tightens and relaxes which allows for more blood to enter the left ventricle. As the heart muscle tenses and relaxes, it allows for blood to flow into the ventricles, atria and various times. Allowing a full intake and out-take of blood. What is special about the pulmonary artery and vein? Why? The veins around the body generally transport deoxygenated blood from places in the body back to the heart, however, the pulmonary vein is one of the few veins that hold and transport oxygenated blood through the body. However, the pulmonary artery carries deoxygenated blood, and the pulmonary vein transports oxygenated blood. Labelled diagram of the

The liver has a portal vein as well as a hepatic vein. It also has unique exchange blood vessels similar to capillaries, called “sinusoids.” How do these unique structures determine the function of the organ? • The livers main function is to filter and process the blood it receives. The portal vein and hepatic vein then deliver the nutrient rich blood to the capillaries (sinusoids).

Normally, low-oxygen blood entering the right side of the heart stays on the right side, and subsequently oxygen-rich blood stays on the left side of the heart, where it is then pumped to the body and tissues. When a defect or "hole" is present between the atria (or upper chambers of heart), some oxygen-rich blood leaks back to the right side of the heart. It then goes back to the lungs even though it is already rich enough in oxygen. Because of this, there is a significant increase in the blood that goes to the lungs overall. Atrial septal defects can

Vesalius had observed, by dissection, that there were no pores in the septum of the heart. This meant that direct transfer of blood was not possible. Harvey’s explanation for how blood was transferred from the right ventricle to the left ventricle was that it went through the lungs via the pulmonary arteries and returned through veins to the left auricle, and subsequently to the left ventricle. Once again this description was a simplified explanation of flow in line with his observations and those of Vesalius and

Because of this the blood goes in through three different streams and then later meets up, which causes stress for the heart. A lot of stress on an already weak heart can cause major damage and possibly kill the patient. The heart can only withstand a certain amount of velocity of blood or else it will deteriorate the tissue causing the heart to start losing its function. The tissue of the left ventricle is very thick which allows it to take the pressure of the blood and to push blood to the rest of the body, but the right ventricle is not made to withstand high pressure or high velocity, meaning that problems would

1. Explain the function of the heart, and the structure of the arteries veins and capillaries The heart is a key muscular organ, and is controlled by the autonomic nervous system. It transports blood to the body’s tissues via the circulatory system; blood provides the body with oxygen, nutrients and also assists in the removal of carbon dioxide and metabolic wastes, hormones are transported throughout the body by plasma. Arteries, arterioles, veins, capillaries and valves, are the blood vessels which are responsible for transporting the blood throughout the body.

That is the structure of the heart, and that so happens to be the most important organ in an organism’s body. The heart helps people get oxygen, keep the organs alive, and it keeps us alive. If this major organ fails and has problems, them that will be really bad. Although There are other major problems in the health world, cardiac problems should be prioritized by doctors.

If a person does not have a cardiovascular system that is in good working order, it can be a fatal situation. Along with pumping blood to the body, the cardiovascular system also brings oxygen and nutrients to all of the different organs and tissues within the body. As our blood makes its circuit journey from the heart to the extremities and then back to the heart, waste is removed from the cells as well. For the cardiovascular system to function at an optimal level, it needs to be healthy and fit.

Furthermore, organs in your body may not get the oxygen and supplements they have to work legitimately. Heart failure is a perpetual (progressing) condition that creates after some time. It is typically created by fundamental conditions, for example, hypertension or coronary illness. These conditions harm your heart, making the heart muscle hardened or thick. The harmed muscle either can't unwind appropriately to let the pumping assemblies of the heart, the ventricles, load with enough blood, or it can't contract legitimately to give the ventricles a chance to pump sufficiently out blood.

The heart is a hollow muscle that is about the size of a fist. In one minute, it pumps about five liters (roughly five quarts) of blood through the body, it is made up of four chambers as shown in Figure 2 .1 Right Atrium (RA), Left Atrium (LA), Right Ventricle (RV), Left Ventricle (LV). An ECG is a diagnosis tool that reported the electrical activity of heart recorded by skin electrode. The morphology and heart rate reflects the cardiac health of human heart beat [16].

The measure of the changing of fluid pressure in the circulatory system is defined as blood pressure. Blood pressure is the measured as the force per unit area applied on the walls of the blood vessels, especially the arteries. Systole is the peak pressure produced by the contraction of the left ventricle, which is followed by a fall in pressure, termed diastole, when the left vernicle relaxes in preparation for the next contraction. The standard blood pressure is measured at 120/8 mmHg, where the top represents the systolic pressure and the bottom represents the diastolic pressure.

Cardiovascular Response to Exercise Introduction The cardiovascular system, comprising of blood vessels, the heart, and blood, responds predictably with regards to the increased exercise demands (Centers for Disease Control and Prevention 62). In a sense, a series of cardiovascular changes take place in response to physical exercise for providing enough blood supply to the constricting muscles, to dissipate the energy produced by active muscles, and to maintain the supply of blood to vital organs of the body such as the brain and the heart (Agarwal et al. CC06).

The airways, the lungs, the blood vessels and the muscles attached to them make up the respiratory system in the human body. All of these work together in the respiratory system to make sure an individual can breathe. Its function is to supply oxygen to everywhere in the human body. It does this through breathing because when a person breathes they breath in (inhale) oxygen rich-air and after that breathes out (exhale) carbon dioxide filled air. The airways in the respiratory system incorporate the nose, mouth, voice box, windpipe and bronchial tubes.
