Cholesterol is excreted in the _______ and waxes are excreted in the _____.

Answer

To answer the question, we need to identify where cholesterol and waxes are excreted in the human body.

**Step 1: Understanding the excretion of cholesterol**
- Cholesterol is primarily excreted in the bile. The liver produces bile, which contains a mixture of bile acids, cholesterol, and other substances.
- Approximately 95% of bile acids are reabsorbed in the intestines, but the remaining bile, which includes cholesterol, is excreted in the feces.

**Step 2: Understanding the excretion of waxes**
- Waxes are excreted through the skin. The skin has sebaceous glands that produce sebum, which is a wax-like substance.
- Sebum contains lipids, including waxes, sterols, and fatty acids, which are secreted onto the skin's surface.

**Final Answer:**
Cholesterol is excreted in the **bile** and waxes are excreted in the **skin**.
