Broken hearts

Bio 204 Basic Anatomy & Physiology Final Exam (Fall 2016) Please use your own words and give examples where necessary. 1. Define homeostasis, and state why it is a central concept for physiology. How does negative feedback differ from positive feedback? (5) Homeostasis is when the internal environment of the body remains relatively constant. It’s the body’s ability to maintain a stable internal environment that is relative to its surroundings. Negative feedback is when the receptor is triggered the

In Focus on Pharmacology Essentials For Health Professionals, Jahangir Moini states “angina pectoris is a common form of ischemic heart disease and often precedes and accompanies MI” (Moini, 2013. p.359). When having angina, a patient will feel pressure in the chest like a squeezing sensation and the pain can travel to the jaw, down the arm, into the neck, shoulders, or back. There are three types of angina: stable, unstable, and variant. Most common types are stable and unstable. Stable angina

artery, heart attack or stroke can result. Another condition called peripheral artery disease can develop when plaque buildup narrows an artery supplying blood to the legs” (http://www.heart.org/HEARTORG/Conditions/Cholesterol). HDL, high-density lipoprotein, is sometimes called the ‘good ’cholesterol because “it helps remove LDL cholesterol from the arteries. Experts believe HDL acts as a scavenger, carrying LDL cholesterol away from the arteries and back to the liver, where it is broken down and

C6H12O6 + O2 = E + CO2 + H2O OR Glucose + Oxygen = Energy + Carbon Dioxide + Water In order to release energy we need glucose which is a simple carbohydrate that is produced after digestion of food and we also need oxygen. Once the food has been broken down it then needs to be transported throughout the body. For this reason, there are three systems involved in cellular respiration. These three systems are known to be the digestive, respiratory and

like a graduation, wedding, or funeral. For others, stress can be brought on by something as small as the broken corner of a Pop-Tart. While we all stress in different degrees because of different circumstances, there is one factor about stress that remains prevalent for everyone. Stress has a major impact on our bodies. When a person experiences periods of stress, their brain, their heart, their muscular system, their digestive system, and their immune system all come out worse for wear. It is

of legs and pelvis. This disease primarily effects voluntary muscles such as muscles of the hips, pelvic area, thighs and shoulders. Since this disease effects all your muscles they’d weaken your heart as well. Most people with BMD often develop cardiomyopathy ( disease in the heart muscle). The heart muscle deteriorates like the skeletal and smooth muscles which would make it difficult to walk, people with BMD might waddle a little they may walk on their toes or stick out their abdomen. Symptoms

of blood through the heart, out to the body, and back to the heart. Start at the inferior/superior vena cava. Include what kind of blood (oxygenated/deoxygenated) is circulating. Use correct terminology and anatomical terms. You may draw a diagram and use colored pencil/marker/crayon/pen to illustrate. • Deoxygenate Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. • blood flows from

wheels of eBay. Once your hands, feet and back are broken in, it's easier to cope with the vibration through the bike. Riding provides you a huge cardiovascular exercise, and your heart has to work more to deal with cycling longer miles, higher paces and more demanding courses. Adapting to those stipulations assists the heart grow tougher, and if maintained, can really decrease the danger of heart disease and lower the heart rate. A tougher heart benefits you as you're in the saddle, it makes daily

body – the heart (and subsequently the cardiac cycle) provides the power to this system. The cardiac cycle is the sequence of steps that are carried out when the heart beats. There are two main phases of the cardiac cycle; the diastolic phase and the systole phase. The diastole phase causes the heart to fill with blood and the systole phase moves the blood from the heart to the arteries. One cardiac cycle is completed when the heart fills with blood and then is pumped back out of the heart. The two

You may have heard of an older gentleman watching what he eats because of a high cholesterol reading on a blood test, or a doctor rambling on and on about how cholesterol causes heart disease which causes death. Many people refer to cholesterol as "the silent killer" but some claim that it is necessary for the every-day functioning of our complex bodily systems. Is there a right answer, or is it a combination of both? According to an article in MedicalNewsToday, "Cholesterol is both good and bad
