EXPERIMENT #1: Representing Systems and Models: The Tea Lab HOMEWORK QUESTIONS: 1) An open system exchanges matter and energy with its surroundings. A closed system exchanges energy but no matter with its environment. An isolated system exchanges neither matter nor energy with its environment. Isolated systems do not exist naturally though it is possible to think of the entire universe. The tea system is an open system because it exchanges energy (heat) with its air/surroundings. 2)

Compare the Circulatory system and the Lymphatic system Closely connected with the blood and circulatory system‚ the lymphatic system is an extensive drainage system that returns water and proteins from various tissues back to the blood stream. When blood reaches the arterial end of the capillary beds in the body tissues‚ fluid from the plasma is forced out of the capillaries by the blood pressure in to a space between the capillaries and the tissue cells. This fluid‚ called tissue fluid‚ is plasma

The Circulatory System The Circulatory System is designed to deliver oxygen and nutrients to all parts of the body and pick up waste materials and toxins for elimination. This system is made up of the heart‚ the veins‚ the arteries‚ and the capillaries. Circulation is achieved by a continuous one-way movement of blood throughout the body. The network of blood vessels that flow through the body is so extensive that blood flows within close proximity to almost every cell. Heart The heart

functions have certain basic characteristics that permit transient and steady-state analyses of the feedback-controlled system. Five factors of prime importance in feedback-control systems are stability‚ the existence and magnitude of the steady-state error‚ controllability‚ observability‚ and parameter sensitivity. The stability characteristic of a linear time-invariant system is determined from the system’s characteristic equation. Routh’s stability criterion provides a means for determining stability
