The correct Answer is:
To determine the level at which the trachea divides into the left and right primary bronchi, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Structure of the Respiratory System**: The trachea, commonly known as the windpipe, is a crucial part of the respiratory system that conducts air to the lungs. 2. **Identify the Division Point**: The trachea bifurcates (divides) into the left and right primary bronchi. This division is an important anatomical landmark. 3. **Locate the Vertebral Levels**: The human vertebral column is divided into several regions: - Cervical vertebrae (C1 to C8) - Thoracic vertebrae (T1 to T12) - Lumbar vertebrae (L1 to L5) - Sacral vertebrae (S1 to S5) - Coccyx (vestigial tail) 4. **Determine the Specific Level**: The trachea divides into the primary bronchi at the level of the thoracic vertebrae. Specifically, this occurs around the level of the 5th thoracic vertebra (T5). 5. **Conclusion**: Therefore, the trachea divides into the left and right primary bronchi at the level of the 5th thoracic vertebra. ### Final Answer: The trachea divides into the left and right primary bronchi at the level of the 5th thoracic vertebra (T5). ---

    Which of the following statements about the human respiratory system are INCORRECT ? I. During swallowing , glottis can covered by a thin elastic cartilaginous flap called epiglottis to prevent the entry of food into the larynx. II. The trachea is a straight tube extending up to the mid- thoracic cavity, which divides at the level of the fourth thoracic vertebra into a right and left primary bronchi. III. The trachea , primary secondary and tertiary bronchi, and initial bronchioles are supported by incomplete cartilaginous rings made up of hyaline cartilage. IV. The respiratory part transports the atmospheric air to the alveoli, clear it from foreign particles, humidifies and also brings the air to body temperature.
