What Does the Left Ventricle Do? The left ventricle is the main pumping chamber of the heart, and it is responsible for pumping oxygen-rich blood to the entire body, as stated by the American Heart Association. The human heart consists of four chambers: the right atrium, the right ventricle, the left atrium and the left ventricle.

Heart Disease: Heart Valve Disease The four heart valves make sure that blood always flows freely in a forward direction and that there is no backward leakage. Blood flows from your right and left atria into your ventricles through the open mitral and tricuspid valves. When the ventricles are full, the mitral and tricuspid valves shut.This prevents blood from flowing backward into the atria while the ventricles contract (squeeze).he four heart valves make sure that blood always flows freely in a forward direction and that there is no backward leakage.

Premature Ventricular Contractions (PVCs, PVC) 1 The atria deliver blood to the ventricles, and the ventricles deliver blood to the lungs and to the rest of the body. 2  The right ventricle delivers blood to the lungs while the left ventricle delivers blood to the rest of the body.  The heartbeat (pulse) that we feel is caused by the contraction of the ventricles.

About the Heart What Heart Valves Do. Heart valves open when the heart pumps to allow blood to flow. They close quickly between heartbeats to make sure blood does not flow backward. Any trouble in this normal flow will make it hard for the heart to pump the blood where it needs to go.

What Is the Difference between the Atrium and Ventricles? The left ventricle receives the clean blood from the left atrium and pumps it into the aorta, which is the largest artery in the body. The aorta then carries the blood to the rest of the body. Another difference between the atrium and ventricles is the valves they are attached to. Heart valves serve as a sort of seal, which open when blood is pumped from one area to the other and closes to prevent the blood from leaking backward.

Auricle An auricle is a feature of the anatomy of the heart. There are two auricles in the heart. One auricle is attached to each of the anterior surfaces of the outer-walls of the atria (that is, the left atrium and the right atrium). Visually, they look like wrinkled pouch-like structures.

Basic Ear Anatomy External Ear. The external ear is made up of the auricle, the external auditory canal (ear canal) and the outer surface of the ear drum or tympanic membrane. The auricle functions to collect and amplify sounds in the environment and aids in determining the direction from which a sound is coming.

Auricle (anatomy) Amplification of sound by the pinna, tympanic membrane and middle ear causes an increase in level of about 10 to 15 dB in a frequency range of 1.5 kHz to 7 kHz. This amplification is an important factor in inner ear trauma resulting from elevated sound levels.he auricle or auricula is the visible part of the ear that resides outside of the head. It is also called the pinna (Latin for wing / fin, plural pinnae), a term that is used more in zootomy.

- Your heart is a muscular organ that acts like a pump to continuously send blood throughout your body. Your heartbeat occurs when the atria and ventricles work together, alternately contracting and relaxing to pump blood through your heart. The electrical system of your heart is the power source that makes this possible.

Auricle The auricle is also known as the pinna, and it is most commonly referred to as the ear. It is the most obviously visible part of the auditory system. An auricle consists of skin over contoured cartilage, and it is held in place by muscles and ligaments.uricles are located on both sides of the head, near the temple and where the jaw meets the skull. Each ear is subdivided into the several regions. These include the lobule, the concha, the scafoid fossa, and other parts. The ear is the first part of the body to come in contact with auditory stimuli.

Auricle physiology of hearing. The outer ear directs sound waves from the external environment to the tympanic membrane. The auricle, the visible portion of the outer ear, collects sound waves and, with the concha, the cavity at the entrance to the external auditory canal, helps to funnel sound into the canal. Because of its small size and virtual immobility, the auricle in humans is less useful in sound gathering and... Read More.

- For other uses, see Atrium. The atrium (plural: atria) is one of the two blood collection chambers of the heart. It was previously called the auricle, but that name is now used for an appendage of the atrium. The atrium is a chamber in which blood enters the heart, as opposed to the ventricle, where it is pushed out of the organ. It has a thin-walled structure that allows blood to return to the heart. There is at least one atrium in animals with a closed circulatory system.

Heart The upper chamber is called an atrium (or auricle), and the lower chamber is called a ventricle. The two atria act as receiving chambers for blood entering the heart; the more muscular ventricles pump the blood out of the heart.
