Tachycardia is a condition marked by an abnormally fast or irregular heart rate, surpassing the typical resting rate. In adults, tachycardia is characterized by a pulse rate ranging from 100 to 180 beats per minute. The increased heart rate can result in inadequate blood flow to various body parts, ultimately diminishing the oxygen supply to organs and tissues. Many factors can elevate the risk of developing tachycardia. These include advanced age, a family history of arrhythmias, and an...

Source: Ricardo Mejia-Alvarez and Hussam Hikmat Jabbar, Department of Mechanical Engineering, Michigan State University, East Lansing, MI The purpose of this experiment is to demonstrate the calibration of a flow passage as a flowmeter using a control volume (CV) formulation [1, 2]. The CV analysis focuses on the macroscopic effect of flow on engineering systems, rather than the detailed description that could be achieved with a detailed differential analysis. These two techniques should be...

Pulmonary hypertension is associated with a significant reduction in pulmonary artery pulsatility, contractility and elasticity, contributing to an increase in pulmonary artery pressure and pulmonary resistance. Using a hypoxic piglet model, this study demonstrated that improving pulmonary artery plasticity using a newly developed pulsatile catheter improves hypoxic pulmonary hypertension.

Renal Drug Excretion: Effect of Urine pH, Flow Rate, and Drug pKa

The pH of urine, the drug's pKa, and the urine flow rate are vital parameters for drug reabsorption and excretion. Urinary pH varies between 4.6 and 8.0 and is influenced by diet, drug intake, and the patient's pathophysiology. It affects a drug's ionization state and reabsorption. For instance, carbohydrate-rich food produces alkaline urine promoting drug excretion, while proteins and certain medications like ascorbic acid lead to acidic urine enhancing reabsorption. The pKa of a drug,...
FAQs
A larger pressure difference across a biological pathway provides a stronger driving force for movement. When resistance remains relevant to the pathway, this can raise the amount passing a reference point per unit time. Examining that change helps link transport behavior to pressure conditions in physiology and experimental systems.
Vessel widening can increase flow because it lowers resistance to blood movement. This changes the relationship between the pressure gradient and the amount transported, rather than simply adding fluid at the source. Comparing narrowed and widened conditions can show how diameter-dependent resistance influences circulation and tissue delivery.
Yes. An increase can reflect either a stronger pressure gradient or reduced resistance, so the same observed outcome may have different causes. Separating these possibilities matters when interpreting experiments: a change associated with vessel diameter suggests altered resistance, whereas a change in driving pressure points to a different transport condition.
Researchers can quantify the volume passing a selected point during a defined time interval, then compare that value across conditions. Repeating the measurement after changing pressure or vessel diameter helps identify whether transport has increased. This approach supports comparisons among circulation, respiratory exchange, and other experimental transport systems.
Changes in flow rate provide information about blood circulation, respiratory exchange, and cellular nutrient delivery. In each case, altered transport can indicate that the movement of fluid, gas, or particles has changed through a biological system. Measurements can therefore connect physical transport conditions with the function of tissues and cells.
Tracking changes in flow rate can reveal how tissues respond to activity, disease, or treatment. A measured increase may indicate altered pressure conditions, reduced resistance, or vessel widening, but interpretation requires considering which variable changed. Comparing transport before and after a condition helps researchers evaluate its effect on biological function.
