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

The Cardiovascular System CHAPTER SUMMARY The importance of the cardiovascular system cannot be overstated. This is one system that students frequently know something about‚ at least from a plumbing viewpoint‚ but they often don’t completely understand the complexity of the system and the magnitude of its tasks. An essential component of presentation of the material is then to outline in detail the role of the cardiovascular system and its significance to all other body systems. This chapter begins

Drugs and the nervous system Neurotransmitters within the body include excitatory and inhibitory‚ noradrenalin‚ dopamine‚ serotonin; acetylcholine and glutamate are examples of excitatory neurotransmitters. GABA and glycine are examples of inhibitory neurotransmitters. General anaesthetics General anaesthetics act mainly on the central nervous system to stop information processing; these may be given by inhalation or intravenously. Nitrous oxide or laughing gas is used in maintain anaesthesia

The two organ systems in the human body I chose were the lymphatic system and the integumentary system. The lymphatic system is there to help fight off diseases and is vital part of the immune system. Integumentary system function is to protect you against infection and other homeostasis. They both play an important role within the human body because we need to protect

oral cavity‚ is the first part of digestive system. The tongue‚ teeth‚ hard palate and soft palate helps to mix and to reduce size of food put into the mouth. The parotid glands‚ the sublingual and the submaxillary grans secret saliva to help the process of chewing food. Saliva contain salivary amylase enzyme responsible for breaking down sugars and starches. The epiglottis prevents food from entering the larynx-at the upper-part of the respiratory system. The tongue helps also to swallow the food

1. What do those numbers (130/87) mean? What do they relate to in the cardiac cycle? The numbers 130/87 is the blood pressure of the patient. The top number 130‚ is the reading that is received when the heart is in contraction and blood is pushed out of the heart into the rest of the body (this is called systole). The bottom number 87‚ is the reading when the heart is at it relaxed state and is being refilled with blood (this is called diastole.) 2. This deposition of platelets and fibrin can

Structures and functions of the Digestion System This essay aims to explain the structure and functions of the digestion system‚ starting from consuming a cooked dinner to chemical and physical changes within the body‚ to prepare or help absorption of vital nutrients and help disposal of waste. The structure of the digestive system starts with the gastrointestinal tract‚ it is a tube that runs from the mouth to the anus and because of this some scientist says it is an external organ; there
