TAQ 6

Postby KatieLouNew » Wed Mar 27, 2013 10:26 pm

TAQ 6...I've explained the cardiac cycle and cardiac conduction system (sino-atrial nodes etc)...the criteria states to explain the dual circulatory system, is this referring to the cardiac cycle and cardiac conduction system? Because when I google 'dual circulatory system' it refers to a circuit linking heart and lungs and the other circuit linking heart to rest of the body. Can someone please clarify what is meant by the dual circulatory system?
Thankyou.

Hiya

the dual circulatory system means 'once around the lungs and then around the body' and the four chambered nature of the heart to facilitate this, if you see what I mean since really the heart is a double pump it just happens to do the pumping to both lungs and the rest of the body

I hope this helps
