Abstract:
Methods to check the back-feed resistivity of the artificial heart valve in static mode have been worked out. These methods allow one to check the resistivity of the closed valve to the revert liquid flow or liquid leakage through it when the new prostheses are tested. The comparative tests of two biovalves and eight mechanical prostheses were carried out. It was stated that among the mechanical valves, which are most widely used in the hospitals (disk, ball and triaflet) the highest resistance when closed has the silicon ball aortic valve AKCh-4-0.6 (Sh).

01:14Design Example: Frog Muscle Response
A student is tasked to work on an intriguing experiment involving an RL (Resistor-Inductor) circuit to study the muscle response of a frog's leg to electrical stimulation. The RL circuit plays a crucial role in this experiment, providing the means to control and measure the electrical impulses that trigger muscle contraction.
When the switch connecting the RL circuit is closed, a brief muscle contraction is observed. This is because, at a steady state, the inductor acts like a short circuit,...

01:16Heart Valves
The human heart is a complex organ with an intricate system of valves that regulate blood flow. There are two main types of valves: atrioventricular (AV) valves and semilunar valves.
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
