My Questions:- Can you clarify the difference between active and passive tensions ?- Why when the passive tension = active tension, the heart will not contract ?- What would the graph be like if that occurs ? ( i.e. What does the "the point of meeting of the 2 curves" mean or look like ? )
Hadn't come across this graph before.
Colin2B,I'm so glad to receive your reply.- First of all, thanks a lot, you have clarified it a bit for me.
And concerning my third question: I think you had already answered it perfectly. ( i.e. the 2 curves never meet each other -which means that they never become equal as illustrated in the graph- except at Cardiac standstill.
