What is the concept?
Concept to my understanding means an idea which is essential or core to understanding the topic or subject. For example Blood Pressure, optmal, low or high means what? To understand blood pressure and how volume, pressure and flow dynamics affects it; I need to know the role of vessel diameter, volume and density of blood plus distance for the blood to travel.
Would someone be able to comment that I understand and apply the word concept correctly? or be able to better explain what concept means?
