Questions and Answers
Which of the following is the primary function of the myocardial?
Which of the following is the primary function of the myocardial?
- Production of blood cells
- Hemodynamic (correct)
- Control of the nervous system
- Regulation of blood pressure
What is the difference between extensibility and elasticity of the myocardial?
What is the difference between extensibility and elasticity of the myocardial?
- Extensibility and elasticity are not functions of the myocardial.
- Extensibility and elasticity are interchangeable terms for the same function of the myocardial.
- Extensibility refers to the ability to give strength to blood flow, while elasticity refers to the ability to do work. (correct)
- Extensibility refers to the ability to do work, while elasticity refers to the ability to give strength to blood flow.
What is meant by the term 'hemodynamic' in relation to the myocardial?
What is meant by the term 'hemodynamic' in relation to the myocardial?
- The control of the nervous system
- The ability to regulate blood pressure
- The heart's ability to act as a pump (correct)
- The production of blood cells
Study Notes
Myocardial Functions
- The primary function of the myocardial is to generate force to pump blood throughout the body.
Myocardial Properties
- Extensibility of the myocardial refers to its ability to stretch and increase in length in response to increased volume, allowing for more blood to enter the heart.
- Elasticity of the myocardial refers to its ability to return to its original shape and size after stretching, enabling the heart to recover its shape between beats.
Hemodynamics
- The term 'hemodynamic' refers to the study of blood flow and the circulatory system, specifically the dynamics of blood movement through the heart and blood vessels, including pressure, flow rate, and resistance.
