Heart failure results in low cardiac output and inadequate filling of the arteries which causes the heart to be unable to pump enough blood to meet with tissue demand of oxygen and nutrients. Consequently, the neurohormonal system activates several feedback mechanisms. The baroreceptors in the aortic arch and carotid sinus that normally inhibit sympathetic nervous system activity are blunted in the patient who is experiencing heart failure. This results in high levels of circulating…

There are two main types of gas exchanges in the respiratory system. Alveolar gas exchange or external respiration and the systemic gas exchange which is also considered to be internal respiration. The Alveolar Gas exchange is the inhalation of Oxygen and the exhalation of Carbon Dioxide into the pulmonary artery. The pressure gradients affect how oxygen can diffuse down across the respiratory membrane from the alveolar air into the blood, or carbon dioxide diffusing from the capillary into…

also nutrients to the body's tissues and organs. This system consists of the heart, blood, and also blood vessels. The heart is a muscular structure that helps push the blood to flow throughout the body. It is composed of three layers the pericardium (around or outside of the heart), the myocardium (middle layer of the heart), and the endocardium (the inside of the heart). The blood vessels consist of arteries, capillaries, and veins. They help to transport blood throughout the body and also…

Introduction: The heart plays a crucial role in the human circulatory system. The large organ pumps the blood through arteries, veins, and capillaries to distribute oxygen and nutrients to the body. The circulatory system also plays a part in removing our waste products. Humans have double circulation, meaning the blood passes through the heart twice before completing one round; this allows for the blood to be “re-pressurized”. Once the right side of the heart receives blood from the body,…

Therefore, this leads to the different types of strokes, which are Acute Ischemic stroke and Hemorrhagic stroke. “ In an ischemic stroke, the blood supply to part of the brain is cut off because atherosclerosis or a blood clot has blocked a blood vessel” (“Acute…”). “Blood clots can travel to the brain from another artery, artery-to-artery embolization, or they can come from the heart,…

1. Explain the relationship between the skeletal and muscular systems. So in the simplest terms, the skeletal system (Bones) make it so that way you have structure in you’re not a blob of skin and cartilage, and the muscular system makes it so that way you can get up and move around. The skeletal system provides the framework for your body, while the muscular system consists of soft tissues that support the skeleton. 2. Why is the circulatory system important? Because it circulates the blood in…

diagnosis: Diagnosis is usually made from patient history and find other causes of heart failure. (The signs and symptoms for heart failure dyspnea, fluid retention, peripheral edema, nausea.) The most helpful tools of the diagnosis is echocardiogram. The chest x-ray identify the heart enlargement. Character’s : • Heart failure symptoms, including unexplained right heart failure • Arrhythmias • Conduction abnormalities • Thromboembolic events • angina pectoris managements : Heart-Healthy…

“Disseminated intravascular coagulation (DIC) is a life-threatening acquired pathologic process in which the clotting system is abnormally activated, resulting in widespread clot formation in the small vessels throughout the body. The pathophysiology is excess thrombin is generated, followed by deposition of fibrin strands in the body tissues.” (Ball, 2012) “The circulating fibrin fragments later begin to interfere with platelet aggregation and other aspects of the clotting mechanism, resulting…

Heart Disease In the world today, there are many harmful and deadly diseases. These diseases are caused by people themselves or they are caused by human nature or probability. One of the many diseases that affect people is heart disease. Heart disease can strike anyone at anytime. The history of heart disease dates back to the Egyptian mummies. Pharaoh Merenptah died from atherosclerosis, which is a type of heart disease. Some early discoveries were made by Leonardo da Vinci and William Harvey…

The circulatory system is composed of vessels that take blood from the heart, thin-walled capillaries where exchange occurs, and vessels that return blood to the heart. Blood is pumped by the heart simultaneously into two ways the pulmonary and systemic circuits. The pulmonary system takes blood through the lungs where gas exchange occurs and the systemic system transports blood to all parts of the body where exchange with tissue fluid takes place. In practical terms, we can think of the…
