Draw a labelled diagram of the human respiratory system.

(N/A) The human respiratory system consists of the following key structures:
$1$. $\text{Nasal passage}$ and $\text{Nostrils}$: Entry points for air.
$2$. $\text{Pharynx}$ and $\text{Larynx}$ (Voice box): Passageway for air.
$3$. $\text{Trachea}$ (Windpipe): Supported by $\text{rings of cartilage}$ to prevent collapse.
$4$. $\text{Bronchi}$ and $\text{Bronchioles}$: Tubes that distribute air into the lungs.
$5$. $\text{Alveoli}$ (Air sacs): Sites of gaseous exchange.
$6$. $\text{Lungs}$: Primary respiratory organs located in the $\text{thoracic cavity}$.
$7$. $\text{Diaphragm}$: A muscular sheet that aids in breathing.
