Which of the following organs secretes hydrochloric acid that helps our body in killing pathogenic bacteria?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3)- Stomach
The organ that secretes hydrochloric acid to kill pathogenic bacteria is the ☀ Stomach.
The stomach is part of the digestive system and has a strong, acidic environment created by hydrochloric acid. This acidic environment helps to:
- Break down food into smaller particles for easier digestion.
- Kill or inactivate some bacteria and viruses that might be present in the food.
The kidneys, heart, and brain don't produce hydrochloric acid. Their functions are:
- Kidneys: Filter waste products from the blood and produce urine.
- Heart: Pumps blood throughout the body.
- Brain: Controls all body functions, thoughts, and emotions.
