Hospital is a place where people a treated for illness or injures.
In modern hospitals, there are two separated entrances and many parts of rooms to treat people dealing with their health. One of these is for patients in need of immediate treatment. It is the emergency entrance. The other entrance is the main entrance of the hospital.
On the ground floor inside the main entrance there are probably a reception area and waiting room, and also an office. On this floor may also be the laundry and the kitchen.
On the floor above and below are numerous other departments, for examples: a maternity section for mothers and their babies, rooms of patients, operating rooms, and special rooms such a radiography room, laboratories, pharmacy, and blood bank.
