Hey there!
The answer would be what to do if someone falls overboard. Finding food is not that hard on a ship and probably not important. Washing the ship Hull is not for the passengers. Navigation lights is for the driver of the boat to use. If someone falls overboard, they could drown if they don’t know how to swim. This is very dangerous.
A congestive heart failure is a condition in which the blood vessels of the heart are not functioning appropriately due to blockages caused by excess fat, hereditary conditions, and poor lifestyle habits.
Ultimately it affects all the body systems and processes because the heart is the organ necessary in pumping blood throughout the body and supplying it with ample oxygen and nutrients. Without the proper functions of the heart, the organ systems will also malfunction causing other complications that may eventually lead to a person's death.
Poor nutrition and lack of sleep.
