Impaired RBX oxygen-carrying capacity
Study Notes
Hyperemia and Congestion
- Increased volume and pressure of blood in a given tissue, associated with capillary dilation and potential fluid extravasation.
Thrombosis
- Can be classified into: venous thrombosis, arterial thrombosis, or cardiac thrombosis (endocardium).
- Thrombus formation influenced by Virchow's triad:
- Alterations in blood flow
- Injury to the blood vessel wall
- Changes in the blood composition
- Thrombus can lead to vascular occlusion, and if the thrombus breaks loose, it can embolize peripherally, affecting organs that require a large volume of blood, such as the brain, kidney, and spleen.
Iron Deficiency
- Lack of available iron leads to decreased hemoglobin synthesis, resulting in impaired oxygen-carrying capacity of red blood cells (RBX).
This quiz covers the concepts of hyperemia and congestion, as well as thrombosis, including its types and the factors that influence thrombus formation.
