Once the blood is in the left ventricle is pushed through the aortic (semilunar) valve into the aorta (the largest artery in the body).īlood is pumped through the body via arteries, from the arteries the blood is pumped into arterioles then into capillaries. The left atrium pushes blood through the atrioventricular (Mitral) valve into the left ventricle. From the pulmonary veins, the blood enters the left atrium. From the right ventricle, the blood is pushed through the pulmonic (semilunar) valve into the pulmonary arteries (which are the only arteries in the body that carries deoxygenated blood).Īfter exchanging gases in the lungs, the now oxygenated blood reenters the heart through the pulmonary veins (which are the only veins that carry oxygenated blood). From there it enters the right atrium where it is pushed through the atrioventricular (tricuspid) valve into the right ventricle. The Path Blood Takes Through The Heart:īlood enters the heart through the superior and inferior vena cava. In a later post, we will explore the physiology (function) of the heart.

This lays out all of the basic structures of the heart that the emergency medical professional needs to concern themselves with. In this post, we will explore the anatomical structure of the heart.

The other two being a person’s airway and ability to breath.

It is one of a triad of life providing aspects of the human body. Given the importance of anatomy and physiology in paramedicine it is recommended that students use additional easy to understand study material.Īs an EMT or Paramedic, the heart’s health and function are among the most important aspects of Emergency Medicine. Below are notes that supplement your class or home study program. The purpose of studying the anatomy and physiology of the heart is to understand how this natural pumping mechanism works. Some organs and tissues take hours or days while others, like the brain, will expire within minutes of being deprived of oxygen. Without the heart, none of the other organs perfused with oxygen and quickly die. The heart functions as a bio-organic pump that ensures the circulation of blood throughout the body. The heart is one of the principal organs responsible for sustaining life.
