Thank you so much both you and the video creator. I have an exam in a few days and this concept wasn't very clear, but it now is thanks to you guys after Allah.

The amount of calcium ion released during each contraction is not completely pumped back into the sarcoplasmic reticulum as the second stimulus is applied within 10 s. Therefore, some residual amount of calcium is left prior to the next stimulus. This increases the quantity of calcium available to the contractile machinery in the next stimulus (the calcium left in the previous contraction plus the calcium released by the present stimulus). Therefore, the second stimulus evokes a bigger response. Similarly, subsequent 2 to 3 stimuli progressively increase the magnitude of contraction. 2. During the first contraction, the temperature in the myocardial cells increases which enhances the enzymatic activity for the muscle contraction. Therefore, the second stimulus acts under the beneficial effect of increased enzymatic activity of the first one. Similarly, few subsequent stimuli progressively increase the height of contraction. 3. The first contraction decreases the viscosity of the sarcoplasm due to increased temperature. Thus, the resistance provided by the sarcoplasm for the second and subsequent contractions is significantly lower than the first one. This increases the magnitude of few subsequent contractions

Why do you speak so aggressively. Well, the video was great, because I got my concept cleared. Thankyou❤❤
