There is less friction between the ice and hockey puck. Concrete is generally more textured and rough, therefore creating more friction

Becuase along the concrete, there is friction because it is not smooth.  The ice, on the other hand, is smooth and has much less friction.

<h2>Baroreceptors </h2>

Explanation:

  • Baroreceptors are splash type nerve endings in the walls of veins and the heart that are invigorated by without a doubt the degree of, and changes in, blood vessel pressure. They are amazingly rich in the mass of the bifurcation of the inner carotid corridors (carotid sinus) and in the mass of the aortic curve. The essential site of end of baroreceptor afferent strands is the NTS.  
  • The capacity of the baroreceptors is to keep up foundational circulatory strain at a moderately steady level, particularly during an adjustment in body position. Flawless baroreceptors are very viable in keeping quick changes in pulse from minute to minute or hour to hour, but since of their versatility to delayed changes of circulatory strain (> 2 or 3 days), the framework is unequipped for long term regulation of blood vessel pressure.
