What is the meaning of right ventricle?
Right ventricle: The lower right chamber of the heart that receives deoxygenated blood from the right atrium and pumps it under low pressure into the lungs via the pulmonary artery. The pulmonary valve is situated between the right ventricle and the pulmonary artery and performs similarly as a one-way valve.
What is the definition of right atrium?
Right atrium: one of the four chambers of the heart. The right atrium receives blood low in oxygen from the body and then empties the blood into the right ventricle.
What is the difference between right and left ventricle?
The left ventricle is the thickest of the heart’s chambers and is responsible for pumping oxygenated blood to tissues all over the body. By contrast, the right ventricle solely pumps blood to the lungs.
What fills the ventricles of the brain?
Cerebrospinal fluid CSF is a clear, watery fluid that fills the ventricles of the brain and the subarachnoid space around the brain and spinal cord.
What is ventricular fibrillation of the heart?
An arrhythmia that starts in your ventricle is called ventricular fibrillation. This occurs when the electrical signals that tell your heart muscle to pump cause your ventricles to quiver (fibrillate) instead. The quivering means that your heart is not pumping blood out to your body.
What is another name for the right ventricle?
Alternate Synonyms for “right ventricle”: ventricle; heart ventricle.
What is the left ventricle of the heart?
Left ventricle: The left lower chamber of the heart that receives blood from the left atrium and pumps it out under high pressure through the aorta to the body. What causes tooth decay?
What causes high blood pressure in the left ventricle?
The most common cause is high blood pressure. Left ventricular hypertrophy is enlargement and thickening (hypertrophy) of the walls of your heart’s main pumping chamber (left ventricle). The thickened heart wall loses elasticity, leading to increased pressure to allow the heart to fill its pumping chamber to send blood to the rest of the body.
Which is the correct definition of a ventricle?

Where does oxygenated blood from the left ventricle go?
The left ventricle receives oxygenated blood from the left atrium via the mitral valve and pumps it through the aorta via the aortic valve, into the systemic circulation.
