Correct option is A
The correct answer is (A) Oesophagus
Explanation:
• The oesophagus (also spelled esophagus) is a muscular tube that connects the pharynx (throat) with the stomach.
• It is approximately 25 cm long in adults.
• Food is moved through the oesophagus by a series of involuntary muscular contractions called peristalsis.
• It passes through the diaphragm before reaching the stomach.
Information Booster:
• Epiglottis: A small flap of tissue that closes the windpipe (trachea) during swallowing to prevent food from entering the lungs.
• Sphincter: The lower oesophageal sphincter is a valve at the bottom of the food pipe that prevents stomach acid from flowing back up.
Additional Knowledge:
• Bladder (Option B): The urinary bladder is a muscular sac in the pelvis that stores urine before it is excreted.
• Intestine (Option C): The small and large intestines are where the majority of digestion and nutrient absorption occur after food leaves the stomach.
• Spleen (Option D): An organ involved in the production and removal of blood cells and part of the immune system; it has no direct role in the passage of food.
