Cholesterol is essential for healthy cells, but if there is too much in the blood it can lead to CAD. Cholesterol is carried in the blood stream by molecules called lipoproteins. Cholesterol is made from eating fatty foods, excess alcohol and caffeine etc. Which means that the more of these you eat the more likely you are to suffer from CAD 3) Carbon monoxide, nicotine, and other substances in tobacco smoke can promote atherosclerosis and trigger symptoms of coronary artery disease. Smoking: * Causes the platelets in your blood to clump together easily by making your blood cells more "sticky" and more likely to form clots.
The pancreas is an organ located behind the stomach that produces chemicals called enzymes, as well as the hormones insulin and glucagon. These enzymes are usually only active after they reach the small intestine, where they are needed to digest food. When they somehow become active inside the pancreas, they digest pancreatic tissue causing swelling, bleeding and damage to blood vessels. Acute pancreatitis affects men more often than women. Certain diseases, surgeries, and habits make one more likely to develop this condition.
The invading organism causes symptoms, in part, by provoking a large immune response in the lungs. The capillaries become leaky, and protein-rich fluid seeps into the alveoli. This results in a less functional area for oxygen-carbon dioxide exchange. The patient becomes relatively oxygen deprived, while at the same time retaining large amounts of carbon dioxide. During this process, mucus production is increased.
The respiratory system has a fairly simple way of cleaning up even though it is a very complex maze of air passages branching off from one another. In a normal, healthy respiratory system the mucus gathers any particles in the lungs that aren’t supposed to be there. The cilia then move back and forth moving the mucus towards the mouth for elimination. Smoking disrupts this entire cycle drastically but also very gradually. It adds more particles and things into the lungs making the amount of mucus larger and larger causing the cilia to work harder.
Most children who develop asthma have a family history of allergies. Early damage to the lungs caused by cystic fibrosis, premature birth, artificial ventilation in an intensive care unit, and certain viral illnesses (especially respiratory syncytial virus [RSV]) can also cause a predisposition to asthma. The severity of asthma varies greatly from child to child. Mild cases may involve only a cough associated with exercise or at night. The milder forms of the disease are the most common, but asthma in its most severe form can result in a catastrophic shortness of breath that leads to death Many simple steps can be taken to reduce asthma triggers in a child's home.
Because of the vast lymphatic network of the esophagus, esophageal cancers spread fast, both locally to regional lymph nodes and distantly to the lungs and liver. Complications include pulmonary problems that result from fistulae and aspiration, including pneumonia and pulmonary abscess; invasion of the tumor into major vessels, causing a massive hemorrhage; obstruction and compression of the other structures in the head and neck; weight loss and nutritional deficiencies due to difficulty swallowing; solid food impaction can result when there is severe stenosis, requiring endoscopic intervention for disimpaction; regurgitation of food or oral secretions may also occur; or the tumor mass may cause compression and obstruction of the tracheobronchial tree, leading to dyspnea(difficulty breathing), chronic cough, and at times post obstructive pneumonia. The most common symptom of esophageal cancer, leading to its diagnosis
URINARY TRACT INFECTION PATHOPHYSIOLOGY: A urinary tract infection (UTI) is an infection in any part of your urinary system — your kidneys, ureters, bladder and urethra. Most infections involve the lower urinary tract — the bladder and the urethra. CAUSES: Urinary tract infections typically occur when bacteria enter the urinary tract through the urethra and begin to multiply in the bladder. Although the urinary system is designed to keep out such microscopic invaders, these defenses sometimes fail. When that happens, bacteria may take hold and grow into a full-blown infection in the urinary tract.
Many diseases affect the respiratory system. The respiratory system is like a sponge, but instead of absorbing water, the system can easily take in airborne viruses that travel in the air. The mouth and nose inhales the air that bacteria are floating in, and brings the infection into the body via respiratory system. The infected goes into the throat and then down the lungs. The infection usually begins in the throat and travels downward to reach the lungs.
One out of every 10 children has asthma. Most children are diagnosed as they are growing up. When parents begin to see that there are many triggers that can easily cause their child to cough continuously or be short of breath, they should immediately suspect that asthma might be the cause. There are three main types of Asthma. One is caused by allergens, another is exercise induced, and the last type is cough-variant asthma.
Alcohol has a biphasic effect on the human body which means that its effects change over time. First, alcohol typically produces feelings of relaxation and cheerfulness then once you drink more and more it can lead to dehydration, coordination problems, blurred vision and even death. One of the worse things I think it causes to your body is dehydration, you need water to stay alive and basically alcohol just sucks it all up. Dehydration can lead to electrolyte an imbalance which is why you get headaches and feel dizzy afterwards. This is also why you get a headache in the morning because your brain swells up from lack of water.
