What is the primary function of maintaining normal blood pressure in the arteries?
Where do impulses originate and travel through in the cardiac muscle?
Why do smaller muscles have a higher metabolic rate?
Study Notes
Blood Pressure Regulation
- The primary function of maintaining normal blood pressure in the arteries is to ensure proper blood flow and oxygen delivery to organs and tissues.
Cardiac Muscle Function
- Impulses that regulate the heartbeat originate in the sinoatrial (SA) node, located in the right atrium, and travel through the atrioventricular (AV) node and the bundle of His to the ventricles.
Muscle Metabolism
- Smaller muscles have a higher metabolic rate due to their increased energy demand to maintain muscle tone and support bodily functions.
