WebFluid Compartments. Figure 2. The intracellular fluid (ICF) is the fluid within cells. The interstitial fluid (IF) is part of the extracellular fluid (ECF) between the cells. Blood plasma is the second part of the ECF. Materials travel between … WebOverview; On the most fundamental level systemic arterial pressure is dependent on the cardiac output and systemic vascular resistance. Recall from hemodynamic integration that for any vascular system the blood pressure gradient = (Blood Flow Volume) x Resistance.The application of this equation to the entire systemic circulation allows for a …

WebDisorders of the Cardiovascular System: Arteriosclerosis. ... This pressure gradient drives blood back toward the heart. Again, the presence of one-way valves and the skeletal muscle and respiratory pumps contribute to … WebTwo factors help maintain this pressure gradient between the veins and the heart. First, the pressure in the atria during diastole is very low, often approaching zero when the atria are relaxed (atrial diastole). Second, … inches to mils conversion calculator

WebA countercurrent system is characterized by very close contact of arterial blood vessels, ideally capillaries, with venous vessels returning from the tissue. In a swimbladder rete mirabile each arterial capillary is surrounded by several venous capillaries, and vice versa. The diffusion distance between venous and arterial vessels is small (in the micrometer … WebJan 17, 2024 · The cardiovascular system is composed of two circulatory paths: pulmonary circulation, the circuit through the lungs where blood is oxygenated; and systemic circulation, the circuit through the rest of the body to provide oxygenated blood. ...
