what is the role of the tubules in the nephron?
assists in the breakdown of food in the small intestine.
regulates the bodys temperature by sweating.
reabsorbs important substances such as water, glucose, and salt from the filtrate, while eliminating waste products such as urea and excess ions.
produces insulin to help regulate blood sugar levels.
transports oxygen from the lungs to the bodys tissues.

Explanation:

The nephron is the functional unit of the kidney. The tubules in the nephron are responsible for reabsorbing important substances like water, glucose, and salts from the filtrate (which is the fluid that has been filtered from the blood in the glomerulus). At the same time, they eliminate waste products such as urea and excess ions.

• The first option is related to the digestive system (small intestine), not the nephron.
• The second option is related to the integumentary system (skin for sweating to regulate temperature).
• The fourth option is related to the pancreas (producing insulin).
• The fifth option is related to the circulatory system (red blood cells transporting oxygen).

Answer:

Reabsorbs important substances such as water, glucose, and salt from the filtrate, while eliminating waste products such as urea and excess ions.
