The lecture Placenta: Blood Flow, Barriers & Exchange by Thad Wilson, PhD is from the course Reproductive Physiology.
Although the lecture content is good. This speaker frequently uses inappropriate sentence structure and phrasing. The result is certain sentences, when spoken, become confusing even though their content is simple. For example...Lets talk about how the placenta and its roles in helping the fetus develop. The sentence makes sense when you read it in the script without having listened to it. However, in the mini-lecture, it was read without pauses or breaks that clarified the emphasis of the sentence. it should have been read as: For example...Lets talk about how the placenta, and its roles in helping the fetus, develop. I know the speaker is likely reading a script, but it happens frequently where his enunciation or sentence delivery does not match the context of sentence. This adds a certain layer of listener confusion which delays the rate at which an individual is progressing through each mini-lecture (4-min lecture becomes 7-minutes). This happens frequently with this speaker and is not a huge deal, until you are forced to listen to all of the physiology lectures, and then become agitated.
