Understand the Problem
The question is asking about various specialized terms related to the structure and function of the heart, such as specific muscles, tissues, and processes involved in heart activity.
Answer
Purkinje fibers, endocardium, vasoconstriction, sinoatrial node, heart murmur, systole, diastole, cardiac catheterization.
A specialized conductive muscle in the ventricle of the heart is known as Purkinje fibers. An inner lining of the heart is called endocardium. A tightening or narrowing of a blood vessel is known as vasoconstriction. A specialized muscle tissue in the wall of the right atrium of the heart is known as sinoatrial node (SA node). An abnormal sound in the heart is called a heart murmur. An active contracting phase of heart beat is called systole. A relaxation phase of heart beat is known as diastole. Inserting a catheter into the heart via a vein is referred to as cardiac catheterization.
Answer for screen readers
A specialized conductive muscle in the ventricle of the heart is known as Purkinje fibers. An inner lining of the heart is called endocardium. A tightening or narrowing of a blood vessel is known as vasoconstriction. A specialized muscle tissue in the wall of the right atrium of the heart is known as sinoatrial node (SA node). An abnormal sound in the heart is called a heart murmur. An active contracting phase of heart beat is called systole. A relaxation phase of heart beat is known as diastole. Inserting a catheter into the heart via a vein is referred to as cardiac catheterization.
More Information
These components are essential for heart function, with specialized muscles ensuring efficient heartbeats and blood flow.
Tips
Confusing the terms systole and diastole is common. Remember systole is contraction; diastole is relaxation.
