blood pressure‚ escape your heart to weak or stiff to fill and pump correctly. Heart failure is caused by many ways one of which includes‚ coronary artery disease‚ a disease of the arteries to supply blood and oxygen to the heart‚ causes decreased blood flow to the heart muscle. CHF is also caused by a heart attack which‚ happens when a coronary artery suddenly becomes jammed‚ stopping the stream of blood to the heart. Furthermore cardiomyopathy‚ damage to the heart muscle from drug and or alcohol

Circulatory systems Closed circulatory systems: • Blood leaves heart under pressure to arteries then arterioles then capillaries. • Capillaries come in large numbers. They exchange substances between the blood and cells. • After passing through capillaries‚ blood goes back to the heart via veins. • Valves in the veins ensure that blood only flows in one direction. Single circulatory system: • Heart pumps deoxygenated blood. • Gaseous exchange (diffusion of CO2 from blood to H2O and diffusion

The cardiovascular system is made up of the heart and blood vessels‚ which are divided into arteries‚ veins and capillaries. The blood delivers nutrients and oxygen to the cells in the body. The arteries carry blood away from the heart and the veins carry it back to the heart. Capillaries are found in the muscles and the lungs‚ they have valves to stop the blood flowing backwards and this is also where gaseous exchange takes place. The heart works as a pump that pushes blood to the organs‚ tissues

lower regions of both lungs. Explain how failure of the left ventricle can cause these signs and symptoms. (4 points). Answer: 4. Heather‚ a newborn baby‚ needs surgery because she was born with an aorta that arises from the right ventricle and a pulmonary trunk that issues from the left ventricle‚ a condition called transposition of the great vessels. What are the physiological consequences of this defect? (4 points) Answer: 5. Gabriel‚ a heroin addict‚ feels tired‚ is weak and feverish‚ and has
Premium Blood Patient Coagulation
Carotid Artery Disease and Stroke Oxygenated blood is carried from the heart to the face and brain by the carotid arteries one on each side of the neck. The carotid arteries (common) bifurcate and become the internal carotid artery (ICA) and the external carotid artery (ECA). Blood supply to the brain is mainly through the internal carotid artery and the vertebral arteries (1). Blood flow to the brain is affected by carotid artery disease. Carotid artery disease is the narrowing (stenosis) or

common form of heart disease is Coronary disease (CHD)‚ and so this is the disease I will investigate. CHD refers to the build up of plaque in the arteries supplying oxygenated blood to the heart‚ also known as Atherosclerosis. The plaque is made up of cholesterol‚ fat and other substances found in the blood. When this build up of plaque occurs‚ the artery narrows‚ as shown in Figure. This will restrict blood flow to the heart‚ and so the heart will be deprived of oxygen and other essential minerals

Chronic diseases are many‚ the most common include heart disease such as angina‚ stroke‚ cancer‚ diabetes‚ respiratory disease such chronic obstructive pulmonary disease (COPD)‚ infectious disease such as tuberculosis. Chronic diseases have severe effect on morbidity and mortality‚ and that is why the public health tries to concentrate on the preventive methods to eliminate the predisposing factors that lead

the diagnosis. The two physiological disorders I will be talking about in this assignment is hypertension and Diabetes. Pulmonary hypertension Pulmonary hypertension is a lung disorder. The arteries that carry blood from the heart to the lungs become narrowed‚ making it very hard for the blood to get through the vessels‚ this then causes the pressure in the arteries to increase more than usual (high blood pressure). Scientists think that the procedure starts with injury to the layer of cells
