Question

As you walk to your classes, your muscle cells are typically conducting _____.

Answer 1

Muscle cells are conducting depolarization waves to stimulate contraction, especially in the heart where a depolarization wave coordinates contractions and propels blood through the circulatory system.

Step-by-step explanation:

As you walk to your classes, your muscle cells are typically conducting depolarization waves that stimulate muscle contraction. In the case of the heart, a depolarization wave is sent across the heart to coordinate its rhythmic contractions and propel blood through the circulatory system. This wave starts at the sinoatrial (SA) node, the heart's natural pacemaker, and spreads through conductive cells across the heart.

Answer 2

is the regrowth of lost tissues or organs in response to injury. This is in contrast to wound healing, which involves closing up the injury site with a scar. Some tissues such as skin and large organs including the liver regrow quite readily, while others have been thought to have little or no capacity for regeneration. However ongoing research, particularly in the heart and lungs, suggests that there is hope for a variety of tissues and organs to eventually become regeneration-capable
