    Vascular Capacitance - definition. Definition: The measure of a BLOOD VESSEL's ability to increase the volume of BLOOD it holds without a large increase in BLOOD vascular capacitance is equal to the change in volume divided by the change in pressure.   Gain a foundational understanding of cardiovascular physiology and how the cardiovascular system functions in health and vascular Physiology, a volume in the Mosby Physiology Series, explains the fundamentals of this complex subject in a clear and concise manner, while helping you bridge the gap between normal function and disease with pathophysiology content throughout the :

In the intestine, the reflex responses of the Capacitance and resistance vessels were always equally pronounced, indicating an essentially uniform reflex.

This functional classification corresponds approximately, but not exactly, to the anatomical divisions. Thus, for example, although resistance vessels largely comprise the small precapillary blood vessels across which most of the drop in blood pressure occurs, all blood vessels offer some degree of resistance to blood : Roger Hainsworth.

Compliance is the ability of a hollow organ (vessel) to distend and increase volume with increasing transmural pressure or the tendency of a hollow organ to resist recoil toward its original dimensions on application of a distending or compressing force. It is the reciprocal of "elastance", hence elastance is a measure of the tendency of a hollow organ to recoil toward its original.

These venous vessels, like the resistance vessels, are capable of dilating and constricting, and serve an important function in regulating capillary pressure. Venules form larger veins that serve as the primary capacitance vessels of the body - i.e., the site where most of the blood volume is found and where regional blood volume is regulated.

Since Hales' time, this concept has been rethought, remodeled, and applied to the pulmonary circulation (Engelberg and DuBois, ; Wasserman et al., ).In its purest form, this concept has been presented as an electrical circuit with a resistor and a capacitor arranged in parallel (Figure 5(A)).This model of the pulmonary circulation has been the departure point for a.

Abstract. Vascular capacitance of an organ or region is defined as the volume of blood contained in it at a particular distending pressure. Since the veins contain about 70% of the total blood volume, these are called the capacitance vessels (Green, ).Cited by: 1.

Small veins and venules in the splanchnic region make up the bulk of the peripheral venous compartment and also exhibit the highest degree of active venoconstriction 51 – Therefore, factors regulating venomotor tone in these vessels are critical in determining active changes in Cited by: Veins - capacitance vessels because they.

Different types of blood vessels vary slightly in their structures, but they share the same general features. Arteries and arterioles have thicker walls than veins and venules because they are closer to the heart and receive blood that is surging at a far greater pressure (Figure ).

Each type of vessel has a lumen —a hollow passageway. Hypovolemic shock causes blood vessels to constrict to increase venous return and maintain pressure. Heart rate increases to compensate for loss of blood pressure and to maintain cardiac output.

If volume loss continues, pressure eventually drops sharply and the shock becomes irreversible, leading to death. Circulatory adjustments are effected by altering the output of the pump (the heart), changing the diameter of the resistance vessels (primarily the arterioles), or altering the amount of blood pooled in the capacitance vessels (the veins).

Regulation of cardiac output is discussed in Chapter The integrity of the venous capacitance system is crucial to the determination of the overall effect of vasoactive compounds on cardiac output and systemic blood pressure.

If peripheral resistance is decreased and the capacitance vessels are simultaneously constricted (elevated preload), the cardiac output will be markedly elevated, but arterial pressure may remain unaltered. Cardiovascular System –Vessels The capacitance of a blood vessel describes the volume of blood a vessel can hold at a given pressure Costanzo (Physiology, 4th ed.) –Figure Compliance = Volume Cardiovascular System –Vessels Cardiovascular System –Vessels ~ File Size: KB.

Due to the high capacitance of the venous system, the majority of the blood would be in the venous circulation. Mean circulatory filling pressure (MCFP), 7 mm Hg, is the mean pressure that exists within the vascular system if pressure is allowed to.

Oxygen delivery to cells is the basic prerequisite of life. Within the human body, an ingenious oxygen delivery system, comprising steps of convection and diffusion from the upper airways via the lungs and the cardiovascular system to the microvascular area, bridges the gap between oxygen in the outside airspace and the interstitial space around the cells.

Regulation of both blood flow and blood pressure is discussed in detail later in this chapter. they are said to be capacitance vessels. When blood flow needs to be redistributed to other portions of the body, the vasomotor center located in the medulla oblongata sends sympathetic stimulation to the smooth muscles in the walls of the veins.
