Study Notes
Deep Vein Thrombosis (DVT)
- A symptom of DVT is pain or tenderness in the affected leg, especially in the calf
- Swelling of the leg, warmth, or redness may also occur
Venous Stasis
- The main cause of venous stasis is immobility or prolonged bed rest
- This leads to blood pooling in the veins, increasing the risk of DVT
Characteristics of Arteries
- Arteries are muscular and elastic, allowing them to stretch and maintain high blood pressure
- NOT a characteristic of arteries is low blood pressure
Ischemia
- Ischemia is a condition where the blood flow is restricted to a part of the body, causing a lack of oxygen and nutrients
- It can be acute or chronic, and can lead to tissue damage or death
Risk Factors for Venous Stasis and DVT
- Risk factors for venous stasis and DVT include immobility, cancer, heart failure, and inflammatory bowel disease
- NOT a risk factor is high blood pressure
Test your knowledge of the circulatory system with this quiz on arteries and veins. Learn about the high pressure system of arteries and the low pressure system of veins, as well as common problems that can occur in both. Explore topics like ischemia, blockages, and the importance of muscle contraction and valve function in venous return.
