6. The Mitral valve or tricuspid valve is leaking. The sloshy sound will be heard during the atrial systole. The dub is heard during the ventricular diastole. The chordae tendinae‚ or heart strings‚ support the atrioventricular valve because the heart strings connects the papillary muscles to the tricuspid and mitral valve. 7. The difference between a quintuple bypass surgery and an open heart valve surgery is that the quintuple heart surgery is an open heart surgery‚in which your chest gets crack

The human heart is a very interesting and complicated part of the body‚ that some struggle to understand. Blood is also a stimulating part of the human body that is really great to learn about‚ as well as blood pressure. Heart disease is a very common disease that many people face‚ so it is important that people are educated about it. There are two sides to the heart and each side receives and pumps different kinds of blood. The left side of the heart is more muscular because it has to pump blood

Introduction Complete atrioventricular canal defect (CAVC) is a heart condition in which there is a large hole in the center of the heart and only one heart valve. Normally‚ the heart is divided into four chambers‚ and there is one valve on each side of the heart. The chambers on the right side of the heart receive blood from the body and pump it to the lungs where the blood gets oxygen. The chambers on the left side of the heart get the oxygen-rich blood from the lungs and pump it back out to the

Cardiovascular System Anatomy & Physiology The heart is the pump responsible for maintaining adequate circulation of oxygenated blood around the vascular network of the body. It is a four-chamber pump‚ with the right side receiving deoxygenated blood from the body at low presure and pumping it to the lungs (the pulmonary circulation) and the left side receiving oxygenated blood from the lungs and pumping it at high pressure around the body (the systemic circulation). The myocardium (cardiac

Introduction In this lab‚ I looked at how exercise affects a person’s heart rate (BPM)‚ systolic pressure‚ diastolic pressure‚ and Mean Arterial Pressure (MAP). Heart rate is measured by beats per minute while systolic and diastolic pressure are measured by millimeters of Mercury. I found the MAP by the following equation‚ MAP= Diastolic Pressure + ⅓(Systolic-Diastolic). We found out that heart rate and systolic pressure were highest right after and during exercise‚ while diastolic pressure and

Exercise 1 (20 marks) 1. What happens to the blood pressure and heart rate when the arterial resistance is increased? When arterial resistance is increased‚ the blood pressure increases and heart rate decreases. For instance‚ when arterial resistance increased to 150%‚ systolic blood pressure increases to 132.8mmHg‚ diastolic pressure increases to 82.1 mmHg‚ and heart rate decreased to 51.8/min. 2. What might give rise to condition with increased

The mechanism of heart contraction and relaxation (mechanical restitution) is the basic of cardiac functioning. This mechanical restitution is driven by calcium movement and concentrations. An increase in cystolic calcium concentration causes contraction in myocardium. Calcium from the extracellular fluid enters the cardiomyocyte through the L-type Ca2+ channels after being propagated by the cardiac action potential which depolarises the cell. This flood of calcium triggers more calcium release

Vietnamese Culture and High Blood Pressure High blood pressure is one of the most serious health conditions worldwide. Often times‚ people have high blood pressure for months or even years without knowing it. Knowledge is very important when it comes to health. High blood pressure can lead to other lethal conditions such as‚ “coronary heart disease‚ heart failure‚ stroke‚ kidney failure‚ and other health problems.” ("What is high‚" 2011) There are many ways that you can avoid high blood pressure

ADVANCED CLINICAL CONCEPTS • ARDS is an unexpected‚ catastrophic pulmonary complication occurring in a person with no previous pulmonary problems. The mortality rate is high (50%) In ARDS‚ a common laboratory finding is lowered PO2. However‚ these clients are not very responsive to high concentrations of oxygen. Think about the physiology of the lungs by remembering PEEP: Positive End Expiratory Pressure is the instillation and maintenance of small amounts of air into the alveolar sacs to prevent
