What role does insulin play in metabolism?
Insulin is a hormone that helps regulate blood sugar by promoting glucose uptake into cells, storing
excess glucose as glycogen in the liver and muscles. ✔️✔️
How does the digestive system break down carbohydrates?
, Enzymes like amylase break down carbohydrates into simpler sugars like glucose, which are then
absorbed into the bloodstream through the intestines. ✔️✔️
What is the function of the stomach in digestion?

function and skin health. ✔️✔️
Why is it essential to maintain healthy blood pressure levels?

Iron deficiency can lead to anemia, causing symptoms like fatigue, weakness, pale skin, and difficulty
concentrating due to insufficient oxygen delivery to tissues. ✔️✔️
How does the body absorb fat-soluble vitamins?
Fat-soluble vitamins (A, D, E, and K) are absorbed in the small intestine with the help of dietary fats and
are then stored in the liver and fat tissues. ✔️✔️
What is the relationship between sodium and fluid balance in the body?
Sodium helps regulate fluid balance by attracting water, and it plays a crucial role in maintaining blood
pressure and proper cell function. ✔️✔️
