is Thromboplastin equivalent to Tissue factor (FIII)?

[@user-gw2zn9qk7g]

A little late here, but Thromboplastin is basically Tissue Factor WITH Negative Phospholipids

technically easy to understand, but it would be good to show some more of the words mentioned, the guys accent is really hard to understand at times even afterrepating the video I still don´t get what he is saying. Pls use native english speakers for upcoming videos, Thank you.

[@ynotspank1]

Excellent. Gonna Go back and review once more just for good measure. Nature is so beautifully complex. You'll never get bored because you'll never know it all! And just when you just might at age 86 or 91, for example, after unrealistically intensive and consistent study, you just may ask yourself, "Is what I know even subjectively and globally accurate in ALL cases?" Probablyyy not. It would be a fruitful life regardless.
