Humans‚ performs gas exchange in order to transport gas‚ nutrients and waste throughout the body. Respiratory system and Circulatory are responsible to carry out the gas exchange. The Respiratory system is composed of nose‚ larynx‚ pharynx‚ trachea‚ bronchi‚ bronchioles‚ pleura‚ alveoli and diaphragm. The Circulatory system consists of the heart‚ blood vessels‚ arteries‚ arterioles‚ veins‚ venules‚ capillaries and blood. In this lab‚ we will only focus on the circulatory system. The heart is the

How do principles of engineering apply to heart structure and function? The heart is a pump‚ just like artificial pumps created by engineers. Biomedical Engineers create things like artificial heart valves & pacemakers to help treat heart problems. 2.3 The Heart at Work Study Guide by Hisrich 2.3.a. In what ways can technology be used to collect and analyze cardiovascular data? Thing measured Blood pressure Tool used Sphygmomanometer “pulse measurer”

one-half million people in the United States have a new or recurrent stroke every year. Believe it or not‚ strokes affect African Americans more than Caucasian and are more likely to cause death in them as well. You can have valve rupture‚ heart failure‚ cardiac tapenade‚ or aortic rupture. Anytime blood does not flow to the brain correctly‚ this will cause a stroke. The blood flow gives nutrients and oxygen to the brain. Without the blood‚ the cell in your brain will begin to die off. Depending

Assessment Mr. Dunn’s blood pressure reading is 189/110. His LDL cholesterol reading is 200 mg/dl. He asks the student nurse if he should be concerned about his blood pressure. 1. How should the student respond? A) "Your blood pressure is very high. You need to see your healthcare provider today." INCORRECT Mr. Dunn’s blood pressure is high. The student nurse needs to assess for other symptoms before making the determination that the healthcare provider must see him that day. B) "You

perfusion technology have facilitated routine totally endoscopic robotic cardiac surgery using the da Vinci telemanipulation system (Intuitive Surgical Inc). This technology has been applied to many cardiac surgical procedures‚ in particular‚ mitral valve repair (MVP) and totally endoscopic coronary artery bypass grafting (TECAB)‚ allowing the surgeon to operate through 5 mm port sites rather than a traditional median sternotomy. In this rapidly evolving field‚ we review the clinical results of robotic

Acute Coronary Syndrome Acute coronary syndrome is a term used for any condition brought on by sudden‚ reduced blood flow to the heart. Acute coronary syndrome symptoms may include the type of chest pressure that you feel during a heart attack‚ or pressure in your chest while you’re at rest or doing light physical activity. Acute coronary syndrome is treatable if diagnosed quickly. Acute coronary syndrome treatments vary‚ depending on your signs‚ symptoms and overall health condition. Acute coronary

Clinical assessment and causes Haemoptysis is a common and non-specific feature of many lung diseases. It can be a sign of significant underlying lung disease. In up to one-third of cases‚ no cause will be found. An early assessment of the likely underlying cause needs to be made and investigated accordingly. Diagnostic approach to haemoptysis Small volume haemoptysis is a commonly encountered problem in the out-patient department. It can be safely and efficiently investigated as an out-patient

An essay on the mechanism of breathing and its control The basic mechanisms involved in inspiration and expiration are as follows; 1)Inspiration The contraction of the diaphragm and external intercostals muscles leading to an expansion of the lungs. This expansion means there is an increase in the volume of the thorax and a decrease in intrapulmonary pressure. A pressure gradient is therefore established from the atmosphere to alveoli‚ hence air being suck into the lower pressure in the lungs

Running Head: AMYGDALA & HYPERSOCIABILITY The Role of the Amygdala and Abnormal Social Behavior in Williams Syndrome Abstract Williams syndrome (WS) is a genetic neurodevelopmental disorder often paired with unique behavioral abnormalities like hypersociability‚ reduced fear and a tendency to approach strangers. The amygdala is an integral component of the neural network and has been implicated in social phenotype particularly in emotion and fear. Functional

heart is more muscular because it has to pump blood from the lungs to pump all over the body. This blood is very oxygenated because it has just come from the lungs. It enters the heart through the left atrium‚ where it is pumped through the bicuspid valve and then into the left ventricle. The right
