THE HEART Anatomy: The heart and heart wall layers: The heart is located in the left side of the mediastinum; it consists of three muscle layers the Endocardium‚ myocardium‚ and epicardium. The epicardium is the outermost layer of the heart. The myocardium is the idle layer of and actual contracting muscle of the heart.

Homeostasis refers to the body ’s ability to keep the internal chemical and physical environments constant. As your body begins to react to stress several changes occur. These changes include increased heart rate‚ blood pressure and secretion of stimulatory hormones

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

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

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. What is the largest vessel that is

In this paper‚ I will focus on Aristotle’s account of the anatomy of the heart and its relation with a network of other organs (modernly known as the cardio vascular system) such as the veins and arteries and their relation to the respiratory functions of organisms. The cardio vascular model that Aristotle describes in works
