The Heart: Structure and Function
This detailed heart diagram labeled illustrates the key components and blood flow pathways of the human heart, essential for understanding heart structure and function in GCSE Biology.
The diagram showcases the four main chambers of the heart: the right atrium, right ventricle, left atrium, and left ventricle. Each chamber plays a crucial role in the circulation of blood throughout the body.
Vocabulary: Atrium - The upper chambers of the heart that receive blood from the body or lungs.
Vocabulary: Ventricle - The lower chambers of the heart that pump blood to the lungs or body.
The right side of the heart handles deoxygenated blood:
- The vena cava brings deoxygenated blood from the body into the right atrium.
- Blood flows from the right atrium to the right ventricle.
- The right ventricle pumps blood through the pulmonary artery to the lungs for oxygenation.
Highlight: Deoxygenated blood arrives at the heart from the body via which vein? The answer is the vena cava.
The left side of the heart manages oxygenated blood:
- Oxygenated blood returns from the lungs via the pulmonary vein to the left atrium.
- Blood moves from the left atrium to the left ventricle.
- The left ventricle pumps oxygenated blood through the aorta to the rest of the body.
Highlight: In which blood vessel does the left ventricle of the heart pump oxygenated blood around the body? The answer is the aorta.
A notable feature of the heart's structure is the difference in muscular thickness between the left and right sides. The diagram emphasizes that the left side of the heart, particularly the left ventricle, has a thicker muscular wall compared to the right side. This adaptation is crucial for its function.
Definition: The left ventricle's thicker wall enables it to generate the higher pressure needed to pump blood throughout the entire body, as opposed to the right ventricle which only pumps to the nearby lungs.
The diagram also highlights the coronary arteries, which branch off from the aorta and spread across the heart muscle. These arteries play a vital role in the heart's own blood supply.
Example: The coronary arteries provide oxygen and nutrients to the heart muscle, which is essential for its continuous contraction and relaxation.
Understanding this structure of heart diagram is crucial for answering GCSE Biology the heart exam questions and comprehending topics like coronary heart disease GCSE biology AQA.
Highlight: Which part of the heart pumps deoxygenated blood to the lungs? The right ventricle performs this function.
This comprehensive overview of the heart's structure and function, as depicted in this heart diagram GCSE AQA, forms the foundation for more advanced topics in cardiovascular biology, including the study of heart diseases and treatments.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.
