Microvascular
Microvascular[edit | edit source]
Microvascular refers to the smallest blood vessels in the circulatory system, including capillaries, venules, and arterioles. These vessels are crucial for the exchange of gases, nutrients, and waste products between the blood and tissues.
Structure[edit | edit source]
The microvascular system is composed of:
- Capillaries: The smallest blood vessels, where the exchange of oxygen, carbon dioxide, and other substances occurs.
- Venules: Small vessels that collect blood from capillaries and transport it to larger veins.
- Arterioles: Small branches of arteries that lead to capillaries.
Function[edit | edit source]
The primary function of the microvascular system is to facilitate the exchange of materials between the blood and tissues. This includes:
- Oxygen and Carbon Dioxide Exchange: Oxygen is delivered to tissues, and carbon dioxide is removed.
- Nutrient Delivery: Nutrients such as glucose and amino acids are transported to cells.
- Waste Removal: Metabolic waste products are carried away from tissues.
Microvascular Diseases[edit | edit source]
Microvascular diseases affect the small blood vessels and can lead to significant health issues. Common microvascular diseases include:
- Diabetic Microvascular Disease: A complication of diabetes mellitus that affects the eyes, kidneys, and nerves.
- Microvascular Angina: A condition where the small coronary arteries do not function properly, leading to chest pain.
- Raynaud's Phenomenon: A disorder that affects blood flow to certain parts of the body, usually the fingers and toes.
Diagnosis[edit | edit source]
Diagnosis of microvascular conditions often involves:
- Angiography: Imaging technique to visualize blood vessels.
- Doppler Ultrasound: A test that uses sound waves to measure blood flow.
- Capillaroscopy: Examination of capillaries under a microscope.
Treatment[edit | edit source]
Treatment of microvascular diseases depends on the underlying cause and may include:
- Medications: Such as vasodilators to improve blood flow.
- Lifestyle Changes: Including diet and exercise to manage risk factors.
- Surgical Interventions: In some cases, procedures to improve blood flow may be necessary.
