**DIAGRAM**: مثلث الحريق
Description: A diagram representing the fire triangle, illustrating the three components necessary for combustion and the resulting fire. It is an equilateral triangle with three corners and a central element. Each corner and the center are numbered.
X-axis: N/A
Y-axis: N/A
Data: N/A
Context: This diagram visually explains the concept of the fire triangle, where heat, fuel, and oxygen are the three essential elements for a fire to occur. The central flame (4) represents the outcome of these three elements combining. Question 1 asks to identify which component represents the main task of the human respiratory system, which is related to oxygen (2).
**DIAGRAM**: N/A
Description: A sagittal (side) view illustration of the human head and neck, focusing on the upper respiratory and digestive tracts. It shows the nasal cavity, oral cavity, pharynx, larynx, and the beginning of the trachea and esophagus. A white line with an arrow points specifically to the larynx/upper trachea region.
X-axis: N/A
Y-axis: N/A
Data: N/A
Context: This anatomical diagram is used in Question 5 to identify the function of the specific part pointed to by the arrow, which is the larynx. The larynx plays a crucial role in preventing food from entering the trachea and in sound production.
