What is Bronchitis?

• A viral infection that affects the lungs.

• An inflammation of the bronchial tubes, often causing coughing and difficulty breathing.

• A condition characterized by excessive mucus production in the stomach.

• A type of allergy that causes respiratory issues.

What is the role of Saliva in digestion?

• To begin the process of digestion by moistening food and containing enzymes that break down carbohydrates.

• To absorb nutrients directly into the bloodstream.

• To neutralize stomach acid before it enters the intestines.

• A condition caused by exposure to cold weather

What is the process of Digestion?

• The breakdown of food into smaller components that can be absorbed by the body.

• The process of breathing in oxygen and expelling carbon dioxide.

• The conversion of food into energy through metabolic processes.

• The absorption of nutrients directly into the bloodstream without any breakdown.

What is the significance of the Diaphragm?

• A muscle that plays a crucial role in breathing by contracting and relaxing to allow air in and out of the lungs.

• A structure that separates the thoracic cavity from the abdominal cavity.

• A muscle that helps in the digestion of food by contracting the stomach.

• A membrane that protects the lungs from infections.

Where does mechanical and chemical digestion begin?

• In the Stomach, where food is mixed with digestive juices.

• In the Mouth, which is the opening to the digestive system.

• In the Esophagus, where food is transported to the stomach.

• In the Small Intestine, where most digestion occurs.

What is the Excretory System?

• The system responsible for removing waste products from the body and regulating water and electrolyte balance.

• The system that circulates blood throughout the body.

• The system that aids in digestion and nutrient absorption.

• The system that controls body temperature and protects against infection.

What is the function of the Gall Bladder?

• To store and concentrate bile produced by the liver until it is needed for digestion.

• To produce insulin for regulating blood sugar levels.

• To filter toxins from the blood and produce urine.

• To absorb nutrients from digested food.

What is the function of the Alveoli?

• To filter air before it enters the lungs.

• To produce mucus that traps dust and pathogens.

• Tiny air sacs in the lungs where gas exchange occurs, allowing oxygen to enter the blood and carbon dioxide to be expelled.

• To transport oxygen from the lungs to the heart.
