How does the heart work GCSE AQA?
Blood from the pulmonary veins enters the left atrium. The atria fill, followed by the ventricles . Blood is prevented from flowing back into the atria by heart valves. Blood leaves the heart in the body’s main artery – the aorta – from the left side, and the pulmonary artery , from the right.
How do you remember the order of your heart?
Just remember this mnemonic for the order of blood flow through the valves:
- Try. Performing. Better. Always. (Tricuspid, Pulmonary, Bicuspid, and Aortic.)
- All. People. Enjoy. Time. Magazine.
- Stenosis of a valve. Partial obstruction. Aneurysms. Mitral or aortic regurgitation. Septal defect.
What is the heart in biology?
The Heart. The heart is a muscular organ in the chest. It consists mainly of cardiac muscle tissue and pumps blood through blood vessels by repeated, rhythmic contractions. The heart has four chambers, as shown in Figure below: two upper atria (singular, atrium) and two lowerventricles.
How does the heart work GCSE PE?
The heart works as a dual action pump – two pumps that work at the same time to pump blood in two different directions. The right-hand side of the heart collects deoxygenated blood from the body and pumps it to the lungs (to collect more oxygen). This is called pulmonary circulation.
What are the parts of a heart?
The heart is made up of four chambers. The upper two chambers are called atria (singular: atrium) and the lower two are known as ventricles (singular: ventricle). Muscular walls, called septa or septum, divide the heart into two sides.

What is the function of the heart?
The heart is a muscular organ. Its function is to pump blood. The cardiac muscle of the heart contracts to pump the blood from the atria into the ventricles and from the ventricles into the arteries.
