procedureIf vasodilation is insufficient to return body temperature to normal, the hypothalamus activates sweat glands to produce sweat, which cools the body through the evaporation of water from the skin.
procedureTo reduce body temperature, the hypothalamus triggers vasodilation, which is the widening of blood vessels in the skin, allowing warm blood to flow closer to the surface and lose heat to the surrounding air.
Chronic Inflammation - StatPearls - NCBI Bookshelf ncbi.nlm.nih.gov 1 fact
claimChronic inflammation retains several features of acute inflammation, including vasodilation (expansion of blood vessels), increased blood flow, increased capillary permeability, and the migration of neutrophils into infected tissue through the capillary wall (diapedesis).
Physiology, Male Reproductive System - StatPearls - NCBI Bookshelf ncbi.nlm.nih.gov 1 fact
claimDuring sexual arousal, vasodilation brings blood to the penis, causing blood to flow into the corpora cavernosa and corpus spongiosum to enlarge and erect the penis.
Homeostasis and Feedback Loops | Anatomy and Physiology I courses.lumenlearning.com 1 fact
procedureWhen body temperature rises, the hypothalamus initiates the following physiological responses: (1) vasodilation of surface blood vessels to increase heat flow to the skin, and (2) release of sweat by sweat glands to cool the skin through evaporation. These responses continue until the body temperature returns to normal.
Homeostasis vs. Allostasis: Why Your Body Needs More Than Stability trueself.health Jan 5, 2026 1 fact
claimWhen human body temperature drops below 37°C (98.6°F), the brain signals muscles to shiver and blood vessels to constrict to generate and conserve heat; when temperature rises, the body sweats and blood vessels dilate to cool down.
Wound Healing Phases - StatPearls - NCBI Bookshelf ncbi.nlm.nih.gov 1 fact
claimIn wound healing, vasoconstriction is a short-lived process that is followed by vasodilation, which allows for the influx of white blood cells and thrombocytes.
The Four Stages of Wound Healing woundevolution.com 1 fact
claimThe inflammation phase of wound healing is defined by vasodilation, where blood vessels dilate to allow enzymes and leukocytes (white blood cells) to enter the wound site to prevent infection.
Medicinal plants and human health: a comprehensive review of ... link.springer.com Nov 5, 2025 1 fact
claimCertain phytochemicals stimulate endothelium-derived hyperpolarizing factor (EDHF) pathways by activating calcium-activated potassium channels, which causes smooth muscle hyperpolarization and vasodilation independently of nitric oxide and prostacyclin pathways.
10.7: Homeostasis and Feedback - Biology LibreTexts bio.libretexts.org Sep 4, 2021 1 fact
procedureWhen the human hypothalamus detects that body temperature is higher than the setpoint, it initiates a cooling procedure: (1) blood vessels in the skin dilate (vasodilation) to radiate heat into the environment, (2) sweat glands are activated to increase sweat output (diaphoresis) for evaporative cooling, and (3) breathing becomes deeper and may shift to mouth breathing to increase heat loss from the lungs.
