Question:
Sweat produced by the sweat glands contains
Sweat produced by the sweat glands contains
Show Hint
Sweat is mostly water with salts, urea and lactic acid.
Updated On: Nov 12, 2026
- NaCl, lactic acid and urea only
- Water, NaCl, lactic acid and urea
- NaCl and urea only
- NaOH, urea and cholesterol
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept
Sweat is made by sweat glands of the skin and cools the body by evaporation.
Step 2: Composition
It is mostly water with dissolved sodium chloride and small amounts of urea and lactic acid, so it also removes a little waste.
Step 3: Eliminate
NaOH and cholesterol are not parts of sweat, since sterols leave the skin in sebum. Options saying 'only' leave out water.
Step 4: Conclusion
Sweat contains water, NaCl, lactic acid and urea.
Final Answer:
Sweat contains water, NaCl, lactic acid and urea. \[ \boxed{\text{(B) }\text{Water, NaCl, lactic acid and urea}} \]
