Heart Valve Transplants The heart‚ the most important organ in the body‚ plays a vital role in a supplying the body with all of the nutrients needed. Not only does the heart pump blood through the body‚ but it also carries oxygen to help the body function correctly and it allows for the removal of waste product. Because the heart is so essential to human body‚ its structure and function is equally as important. The heart is designed to pump blood through its chambers. The top two chambers

During exercise your body must adapt to the added stress and pressure you are putting onto it. The heart plays a very important role in maintaining homeostasis during exercise. When exercising your heart rate increases and the “Left Heart” have to pump out more oxygenated blood to the entire body. The sympathetic nervous system also plays an important role during exercise. The sympathetic pathway comes out of the lower cervical and upper thoracic segments of the spinal cord. The sympathetic

Homeostasis of BP and Heart Rate A normal blood pressure can be identified by having a systolic pressure of around 120 and a diastolic pressure of around 80. This value is expressed as "120/80". A normal heart rate is expressed as the amount of times it beats in a minute; a normal adult heart rate is between 60-100 beats per minute (BPM). There is a relation between these two measurements‚ but they are stimulated by several different circumstances. The blood pressure is mainly affected

The Heart and Circulation of Blood In this research paper‚ I will be analyzing the process of blood circulation within the human body. I will be focusing on the pulmonary circuit and the systemic circuit‚ as well as the relationship with the hepatic portal system. The combination of these systems allows the body to function properly and maintain unconscious homeostasis. I will also be talking about the effects that fitness and diet have on these processes. The pulmonary circuit passes already-used

carries oxygenated blood away from the heart. It supplies the brain‚ right arm‚ and neck with blood. Common carotid artery: The common carotid artery supplies oxygenated blood to the front of the brain as well as the head‚ neck‚ face‚ and spinal cord. Subclavian artery: The subclavian artery carries blood away from the heart and supplies oxygenated blood to the arms. Left pulmonary vein: The left pulmonary vein carries oxygenated blood from the left lung to the heart. Right pulmonary vein: The right

A congenital heart defect (CHD) is an abnormality in the structure or function of the heart. This can include circumstances that affect the walls of the organ‚ blood vessels that transport blood to and from it‚ and the valves that regulate blood flow. Some CHDs are minor‚ and cause no noticeable symptoms. Others are severe‚ and can place the patient’s life at risk. Symptoms vary according to the type of defect suffered‚ as well as its severity. In this article‚ we’ll explore a few of the most common
