The bicuspid valve is also called the mitral valve and is located between the left atrium and left ventricle.

The bicuspid valve is also called the mitral valve and is located between the left atrium and left ventricle.
Ref: NCERT Class 11 Biology Chapter 15: Body Fluids and Circulation Human Heart - Structure and Cardiac Cycle
The right atrium receives deoxygenated blood from the body via the superior and inferior vena cava.
Ref: NCERT Class 11 Biology Chapter 15: Body Fluids and Circulation Human Heart - Structure and Cardiac Cycle
The tricuspid valve lies between the right atrium and right ventricle. It prevents the backflow of blood into the right atrium during ventricular systole.
Ref: NCERT Class 11 Biology Chapter 15: Body Fluids and Circulation Human Heart - Structure and Cardiac Cycle
The left ventricle has the thickest wall to generate high pressure for pumping blood to the entire body.
Ref: NCERT Class 11 Biology Chapter 15: Body Fluids and Circulation Human Heart - Structure and Cardiac Cycle
The left ventricle pumps blood to the aorta, not the lungs. The right ventricle pumps blood to the lungs.
Ref: NCERT Class 11 Biology Chapter 15: Body Fluids and Circulation Human Heart - Structure and Cardiac Cycle
The pulmonary valve prevents backflow into the right ventricle, not the left ventricle.
Ref: NCERT Class 11 Biology Chapter 15: Body Fluids and Circulation Human Heart - Structure and Cardiac Cycle
The left atrium receives oxygenated blood from the pulmonary veins, which carry blood from the lungs.
Ref: NCERT Class 11 Biology Chapter 15: Body Fluids and Circulation Human Heart - Structure and Cardiac Cycle
The right atrium receives deoxygenated blood from the body via the superior and inferior vena cava, not oxygenated blood.

Cardiac muscle fibers are uninucleated, unlike skeletal muscle fibers, which are multinucleated.
Ref: NCERT Class 11 Biology Chapter 15: Body Fluids and Circulation Lymph and Circulatory Pathways
The pericardium is a protective membrane filled with fluid that reduces friction during heartbeats.
