The mitral valve and the tricuspid valve. Answer:   … The heart is made up of four interior chambers. There are two upper and two lower chambers which create the muscle.

The two upper chambers in your heart are called the atria. One on its own is an atrium. This comes from the Latin word for an open entrance area in a house, because the atria are where the blood enters the heart after returning from either the body or the lungs. 1 The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle. 2  The right ventricle pumps the oxygen-poor blood to the lungs. 3  The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle. 4  The left ventricle pumps the oxygen-rich blood to the body. The upper chambers of the human heart are called the atria, atrium singular. There is a left atrium and a right atrium. The atria store blood that is sent downward to the corr … esponding ventricle. Arrhythmias are generally divided into two categories: ventricular and supraventricular. Ventricular arrhythmias occur in the lower chambers of the heart, called the ventricles. Supraventricular arrhythmias occur in the area above the ventricles, usually in the upper chambers of the heart, called the atria. The irregular beats can either be too slow (bradycardia) or too fast (tachycardia). Bradycardia. Confidence votes 2.1K. The upper chambers are called the atria respectively right and left atrium.The lower chambers in your heart are called the left ventricle and the right ventricle. Answer: The heart is made up of four interior chambers. There are two upper and two lower chambers which create the muscle. The atria are the upper right and left chambers and the ventricles create the lower right and left chambers. Chambers of the Heart. The heart has four chambers: two atria and two ventricles. 1  The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle. 2  The right ventricle pumps the oxygen-poor blood to the lungs. 3  The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle. Supraventricular arrhythmias begin in the areas above the heart’s lower chambers, such as the upper chambers (the atria) or the atrial conduction pathways. Generally, supraventricular or atrial arrhythmias are not as serious as ventricular arrhythmias. Atrial fibrillation may cause blood to pool in the heart's upper chambers. The pooled blood can lead to the formation of clumps of blood called blood clots. A stroke can occur if a blood clot travels from the heart and blocks a smaller artery in the brain (a cerebral artery).
