    Welcome to this lecture on the Heart. This is one of my favourite topics in anatomy because the heart is such an incredible organ. We really don?t pause and consider how astonishing the heart is but it?s been estimated that the amount of work that the heart does in one?s lifetime is equivalent to lifting 30 tonnes to the top of Mount Everest. This is coming from a muscle mass of about 300 grams, a little more in the male perhaps a little less on average in a female. But the heart does all this work throughout our lifetime without taking much pause to rest. An incredible organ. And so please join me on this tour of the heart. And as we go on this tour through the heart, at the end of this lesson you should be able to answer the following objectives: describe the pericardium and how the pericardial cavity and sinuses are formed; compare and contrast the anatomy of the four cardiac chambers; list the great vessels and the cardiac chambers that receive them or issue them; describe the sulci, surfaces, base and apex of the heart; describe the cardiac valves with regard to location and number of cusps; describe the coronary circulation with regard to dominance and arterial distribution and then venous drainage. The last objective you should be able to answer is: to describe the cardiac conduction system and the clinical relevance of Koch?s triangle. And then our summary slide will identify key messages that you should take home from this lecture. And then the last slide will provide attribution for the images that were used towards this presentation. This slide is demonstrating the body map. We have a young, well-developed male. And our focus will be on the anterior view to the left. And...

    nice work
    By Ece Ç. on 13. May 2017 for Heart (Cor)

    pretty much understandable and good quality visuals but could be prepared more detailed regarding the chambers of the heart, cusps' orientation and papillary muscles.

    Great lecturer.

    Very good summary of the structures, is straight to the point and is easy to follow.
