THE NERVOUS AND THE ENDOCRINE SYSTEM. Humans need both the Nervous and the Endocrine systems basically because they do different things in different ways. They both have a co-ordination role and send instructions to other parts of the body. The nervous system does this by way of neurotransmitters‚( chemical messengers)‚ which are able to get messages through at very high speeds‚ and the endocrine system by way of hormones‚( also chemical messengers)‚ which are released from glands and travel

The respiratory system of the horse is well adapted to athletic exercise‚ with unrestricted upper airway diameters‚ and a large lung capacity afforded by 18 ribs. These combine to enable air intakes of up to 1800 litres per minute in a galloping horse. Volumes of up to 300 litres of blood are pumped at high pressure through small lung capillaries surrounding 10 million air sacs to take up and deliver over 70 litres of oxygen per minute to the working muscles at the gallop. As a result‚ any restriction

Excretory System Review Main Concepts: Describe the major gross anatomical structures of the excretory system. Kidneys: receive about 25% of the cardiac output; produce urine (a fluid containing water‚ ions‚ and small soluble compounds) Ureters: receive urine from the kidneys and conduct it to the urinary bladder. Urine movement involves a combo of gravity and the peristaltic contractions of smooth muscle in the walls of the ureters Urinary Bladder: receives and stores urine prior to elimination

The principal structure of the digestive system is an irregular tube‚ open at both ends‚ called the alimentary (al-i-MEN-tar-ee) canal or the gastrointestinal (GI) tract. In the adult‚ this hollow tube is about 9 meters (29 feet) long Think of the tube as a passageway that extends through the body like a hallway through a building. Food must be broken down or digested and then absorbed through the walls of the digestive tube before it can actually enter the body and be used by cells The teeth

2 INTELLIGENT AGENTS In which we discuss what an intelligent agent does‚ how it is related to its environment‚ how it is evaluated‚ and how we might go about building one. 2.1 INTRODUCTION An agent is anything that can be viewed as perceiving its environment through sensors and acting upon that environment through effectors. A human agent has eyes‚ ears‚ and other organs for sensors‚ and hands‚ legs‚ mouth‚ and other body parts for effectors. A robotic agent substitutes cameras and infrared
