What is the function of the left ventricle?
What is the function of the left ventricle?
- Transfers blood to the right atrium
- Prevents the backward flow of blood
- Receives de-oxygenated blood from the body
- Pumps oxygen-rich blood to the rest of the body (correct)
What is the role of the right ventricle in the circulatory system?
What is the role of the right ventricle in the circulatory system?
- Pumps de-oxygenated blood to the lungs for oxygenation (correct)
- Prevents the backward flow of blood
- Receives oxygen-rich blood from the lungs
- Transfers blood to the left atrium
Why do the ventricles have thicker muscular walls than the atria?
Why do the ventricles have thicker muscular walls than the atria?
- To relax and collect oxygen-rich blood
- To receive oxygen-rich blood from the lungs
- To pump blood to various organs (correct)
- To prevent the mixing of oxygen-rich and carbon dioxide-rich blood

Study Notes
Circulatory System
- The left ventricle pumps oxygen-rich blood from the heart to the rest of the body.
- The right ventricle pumps oxygen-poor blood from the heart to the lungs to be oxygenated.
Ventricular Structure
- Ventricles have thicker muscular walls than the atria because they need to generate more pressure to pump blood out of the heart and into the circulatory system.
Heart Function
- When the left atrium relaxes, it allows blood to flow from the atrium into the ventricle.
Blood Separation
- It is crucial that oxygen-rich blood and carbon dioxide-rich blood do not mix in the heart because this separation is essential for the proper functioning of the circulatory system.
Mathematics
- Most mathematical activity is described as the process of formulating and proving mathematical statements.
Subdisciplines of Mathematics
- The major subdisciplines of modern mathematics include algebra, analysis, geometry, and number theory.
Mathematical Proofs
- A proof consists of a logical and systematic demonstration of the validity of a mathematical statement.
Mathematical Entities
- The entities in modern mathematics stipulated to have certain properties are called mathematical objects.
Topics in Modern Mathematics
- The topics represented in modern mathematics include algebra, analysis, geometry, number theory, and other areas of mathematical study.
