  130 FACTS ABOUT THE CARDIO-VASCULAR SYSTEM   Here are 100 facts about the cardiovascular system:   General facts:   The cardiovascular system is also known as the circulatory system.   The cardiovascular system is responsible for transporting blood, oxygen, nutrients, and waste products throughout the body.   The cardiovascular system is made up of the heart, blood vessels, and blood.   The cardiovascular system is essential for maintaining homeostasis, which is the stable internal environment of the body.   The cardiovascular system is also involved in regulating blood pressure and body temperature.   The cardiovascular system is one of the first systems to form during embryonic development.   The heart is the muscular organ that pumps blood throughout the body.   The heart is located in the chest, slightly to the left of the sternum.   The heart is surrounded by a sac called the pericardium.   The heart has four chambers: the right atri

  THE DIFFERENT SYSTEMS OF THE HUMAN BODY There are 11 major systems of the human body: Cardiovascular System: This system consists of the heart and blood vessels and is responsible for circulating blood throughout the body.   2.        Respiratory System: This system consists of the lungs and airways and is responsible for bringing oxygen into the body and removing carbon dioxide.   3.        Digestive System: This system consists of the mouth, esophagus, stomach, intestines, liver, and pancreas and is responsible for breaking down food into nutrients that can be absorbed by the body.   4.        Nervous System: This system consists of the brain, spinal cord, and nerves and is responsible for controlling and coordinating all bodily functions and responses.   5.        Endocrine System: This system consists of various glands that secrete hormones into the bloodstream to regulate bodily functions such as growth, metabolism, and reproduction.   6.        Muscular

  ADDITIONAL FACTS ON HOW THE DIFFERENT SYSTEMS OF THE BODY WORKING TOGETHER   1.        The human body has several organs that work together to carry out different functions. 2.        The circulatory system, respiratory system, digestive system, and nervous system are some of the major systems in the body that work together to maintain homeostasis. 3.        The heart is the organ that pumps blood throughout the body and is responsible for maintaining blood pressure. 4.        The lungs are responsible for the exchange of oxygen and carbon dioxide in the body. 5.        The kidneys filter waste products from the blood and maintain fluid and electrolyte balance in the body. 6.        The liver processes nutrients and drugs, and produces bile to aid in digestion. 7.        The pancreas secretes insulin, a hormone that regulates blood sugar levels in the body. 8.        The brain is responsible for coordinating all the functions of the body and is the center of the n
