Answer:
This electrical signal start in the sinoatrial node generates an electrical impulse. From this, the signal passes through the atrioventricular node, which stops the signal for a brief moment and sends it through the muscle fibers of the ventricles, stimulating its contraction.
Explanation:
The electrical impulses generated by the myocardium stimulate the heartbeat. This electrical signal originates in the sinoatrial node located in the upper part of the right atrium. When the sinoatrial node generates an electrical impulse, it stimulates the contraction of the atria. From this, the signal passes through the atrioventricular node, which stops the signal for a brief moment and sends it through the muscle fibers of the ventricles, stimulating its contraction.
The lungs recoil to force the air out of the lungs. The intercostal muscles relax, returning the chest wall to its original position. The diaphragm also relaxes, moving higher into the thoracic cavity.
I cannot see the photo so no, sorry

Answer:
Fracture healing is a biological process in continuum from fracture to healed stage. It involves a sequence of dynamic events which ultimately restores the integrity of the bone and its biomechanical properties.1 Bone is the only biological tissue which heals by making bone and the rest of the tissues heal by making a different tissue. The process of healing starts immediately after injury and continues thereafter. The events take place at the cellular level and the summation of these changes are seen as healing. The fracture healing is influenced by physical, chemical and environmental factors.2
