What is the heart? The heart is the organ that supplies blood and oxygen to all parts of the body. It is about the size of a clenched fist‚ weighs about 10.5 ounces and is shaped like a cone. The heart is located in the chest cavity just posterior to the breastbone‚ between the lungs and superior to the diaphragm. The heart is surrounded by a fluid filled sac called the pericardium. Blood is pumped away from the heart through arteries and returns to the heart through veins. The major artery of the

Premium Hypertension Cardiology Blood pressure
Introduction When the heart beats‚ it pumps blood round the body to give it the energy and oxygen it needs. As the blood moves‚ it pushes against the sides of the blood vessels. The strength of this pushing is your blood pressure. If the blood pressure is too high‚ it puts extra strain on your arteries (and your heart) and this may lead to heart attacks and strokes. Having high blood pressure (hypertension) is not usually something that you feel or notice. It does not tend to produce obvious signs

Short Answer Questions: 1. Dr. Baker spends a long time listening to (auscultating) Caleb’s heart. a.

For the tricuspid valves‚ the sounds of the heart are typically heard in the right sternal margin of the 5th intercostal space. For the Mitral (bicuspid) valve‚ sounds are heard over the heart apex‚ in the 5th intercostal space. This is in line with the middle of the clavicle. (Lutchman

does the heart change as it develops in a fetus? At first‚ the heart is just a tube. It grows so fast that it needs more space‚ so it bends and twists back‚ forming the familiar shape. During the next phase‚ the two atria are partly separate but there is just one big ventricle. The next phase begins when the two atria are completely separate and the ventricles are just beginning to separate. Finally‚ the ventricles separate completely and the heart is developed. 2.
