Answer:
The virus that generates chickenpox disease is a virus of the family called "herpes" where once they infect the human organism they are not eliminated by human defense, but are reserved and coexist in the organism in the lymph nodes, and when faced with immunodeficiency situations for certain reasons, it generates their reactivation, manifesting a recurrence of the disease.
Explanation:
The chickenpox virus is called the Zoster chickenpox virus, once it infects the human in his childhood, it settles in the ganglion near where it is inactively inoculated.
This is reactivated again manifesting shingles or herpes zoster in adulthood and in situations of immunodeficiency as in those malnourished humans, or who are exposed to long hours in the sun, or who suffer stressful situations.
Shingles is a disease that manifests itself in a very painful way (more than chickenpox) in the form of scabs and vesicles in different possible areas.
 
        
             
        
        
        
Answer: diaphragm
Explanation:
The diaphragm separates the thoracic cavity from the abdominal and pelvic cavity.
The diaphragm is a sheet of internal skeletal muscle located below the thoracic cavity that houses the heart and lungs. Below the diaphragm is the abdominal cavity.
The diaphragm plays an essential function for respiration. When the diaphragm contracts, the volume of the thoracic cavity increases so that air is drawn into the lungs.
        
             
        
        
        
Using bar soaps and hand towels won't have a greater chance of making you bleed, but razor blades and toothbrushes do since people usually cut themselves when shaving and toothbrushes can make your gums bleed. 
I hope this helps.
