True or False: Inflammation causes redness, swelling, warmth, and pain.

The statement is true because inflammation is a biological response of the body's immune system to harmful stimuli, such as pathogens, damaged cells, or irritants. This protective mechanism typically manifests through four classic signs: redness, swelling, warmth, and pain.

Redness occurs due to increased blood flow to the affected area as blood vessels dilate, which is part of the body's effort to deliver immune cells and healing factors. Swelling is a result of fluid accumulation in the tissues, often due to the increased permeability of blood vessels during the inflammatory response. Warmth is also related to increased blood flow and metabolic activity in the affected area, and pain arises from the release of inflammatory mediators that stimulate nerve endings, signaling the body to protect the area from further injury.

Understanding these signs as integral components of the inflammatory process is crucial for both identifying inflammation and for structuring appropriate aquatic exercise programs for individuals suffering from conditions like arthritis. Recognizing these symptoms allows program leaders to adjust activities based on the participant's current state, promoting safety and effectiveness in aquatic therapy.
