What organs function as a reservoir for blood?
The sinuses in the spleen are a reservoir for blood. In emergencies such as hemorrhage, smooth muscle in the vessel walls and in the capsule of the spleen contracts. This squeezes the blood out of the spleen into the general circulation.
Do capillaries act as blood reservoirs?
After capillary beds blood is collected in venules which are tributaries of veins. These vessels provide a low pressure blood reservoir through which blood returns to the heart.
Which is an organ that acts as a reservoir for blood?
The spleen is an organ in the body that can also act as a reservoir for blood in case of massive blood loss or hemorrhagic shock. It also filters the blood and recycles iron on destruction of the red blood cells. Understanding D-Day: What Is the History of the Normandy Invasion?
Is the spleen a reservoir for red blood cells?
The Spleen as a Reservoir for Storing Red Blood Cells. Figure 15-13 shows that the spleen has two separate areas for storing blood: the venous sinuses and the pulp. The sinuses can swell the same as any other part of the venous system and store whole blood.
Why are veins considered to be blood reservoirs?
They have thin walls and much wider lumens compared to the arteries, thereby enabling them to contain much more blood than any other human vessel. Veins exist all throughout the body, making them ideal blood reservoirs. These blood reservoirs have a very low pressure and are only able to move blood back…
Where are blood reservoirs located in the brain?
The venous sinuses (also called sinuses of the dura mater) are enlarged vessels, able to relax, and act as blood reservoirs (Saban, 1995; Patel, 2009). Generally, they run within the falx cerebri and tentorium cerebelli, along the anchoring sites in which these connective sheets are attached to the braincase (Fig. 14).
