The parathyroid hormone (PTH) plays a crucial role in regulating calcium levels in the blood. When blood calcium levels are low, the parathyroid glands release PTH. This hormone has several effects that lead to an increase in blood calcium levels.

1. **Bone Resorption**: PTH stimulates osteoclasts, the cells responsible for breaking down bone tissue, leading to the release of calcium from bones into the bloodstream.
2. **Kidney Function**: PTH promotes the reabsorption of calcium in the kidneys, reducing the amount of calcium excreted in urine.
3. **Intestinal Absorption**: PTH indirectly increases calcium absorption in the intestines by stimulating the production of active vitamin D.

Given these mechanisms, the correct answer to the blank is: **increase**.

### Final Answer
**Increase**
