The Human Body The human body is made up of a number of different systems. Each system has a separate function, but some work together. One system is the skeleton, which serves to support the body and protect the internal organs. The respiratory system enables us to breathe and take oxygen into the blood, which moves around the body by means of the circulatory system. The digestive system enables us to take in food needed for growth. Waste matter is ejected from the body by means of the urinary system. The nervous system controls the other systems and enables human beings to think. The endocrine system consists of various glands, such as the thyroid, sex and adrenal glands. The function of these glands is to secrete chemicals, known as hormones, into the blood. These hormones control various processes in the body, such as growth, sexual activities and digestion.. Each system is made up of organs. The lungs, for example, are part of the respiratory system. The heart is an organ in the circulatory system. The liver functions as part of the digestive system and other systems. Every organ is composed of several kinds of tissue. Epithelial tissue, which includes the skin, forms a covering over organs. Connective tissue supports and holds together parts of the body and includes bone and cartilage. Other types of tissue include nerve tissue and blood tissue. All tissue consists of cells. These are so small that they are measured in thousandths of a millimeter and can only be seen with a microscope. Each cell is covered with a thin membrane which surrounds a nucleus, and a jelly-like substance, called cytoplasm. This in turn contains minute particles, each with its own special function.

There are 11 organ systems in the human body and each system has its own function. The Muscular system provides support and protection to other organs and tissue. It also helps in body movement and maintaining heat and body temperature. The digital source by Emma Bryce on “How your muscular system works” explains the types of muscles in the involved in the movement of body.
Epithelia tissue : Epithelial tissue, the type of tissue that lines the surfaces and cavities of your body 's organs, epithelia may be composed of several layers of cells called compound epithelia or just a single layer known as simple epithelia.
The digestive system, in organisms like the mink and human, is supposed to break down the food being eaten to transfer into energy. This energy helps other functions of the body that would in turn keep it alive. The digestive system includes organs such as the stomach, intestines, liver, etc. Digestion starts at the mouth, though.
The heart, blood and blood vessels make up the cardiovascular system. The function of the cardiovascular system is to evenly distribute blood cells, water and nutrients. The cardiovascular system helps send blood to the body’s tissues. The heart is a muscle and the most important part of the cardiovascular system. Heart attacks, heart failure, and abnormal heart beat is a serious issue for the cardiovascular system these can sometimes lead to death. These diseases affect the heart and its functions (Heart and Cardiovascular disease 2005).
The cardiovascular system is made up of a very special type of muscle called cardiac muscle. What is unique about cardiac muscle is that it has to pump involuntarily 24/7 meaning the muscle itself must be very strong and very resilient. The digestive system is made up of smooth muscle which allows food to move along the muscle while remaining in contact with the food in order to aid in digestion. Another big aid to digestion is the folding of the digestive system, both within the system and the system as a whole. Inside the intestines are lined with villi which increase the surface area for digestion immensely while the whole digestive system is folded multiple times to maximize the time for digestion. The respiratory system is filled with blood vessels in order to maximize oxygen absorption. The lungs contain an immense network of blood vessels surrounding structures called alveolus which is where the actual gas exchange happens and thus makes sense that it would have the greatest concentration of blood

All organ system work together; in order to keep and support the conditions that the cells, tissues, and organs need to function properly. Each organ system has an important function in the body. There is one system that is not as well known as other; it is the integumentary system. Most people know the organs of the integumentary system, but they do not know that these organs work together to form this system.
...ng necessary nutrients, such as stomach acid and saliva. The body also uses a waste system to take out the bad stuff in the body that cannot be used as nutrients or energy. Human beings, and all animals from the tiniest insect to the world’s largest mammal, must remove and dispose of wastes from their bodies. Separate systems work on gaseous, liquid, and solid waste. Waste excretion in living things helps maintain homeostasis which supports the basic ability to survive. There are many systems in the human body, from the circulatory which regulates blood flow throughout the body, to the nervous system and muscular system. Each system has its specific function and purpose in the body. However, it is fair to say that the digestive system, with all its necessary organs, enzymes, chemicals and processes is truly one of the most important systems in the human body.
The respiratory system is something we sometimes take for granted; because breathing is something we do without having to think about. It is a system made up of organs, tissues and blood circulation. It is a complex and fragile system that we must take care of if we want to live a healthy life.
Tissues are composed of groups of cells that have similar shapes and functions. There are four main types of tissue found in the human body: epithelial tissue, connective tissue, muscular tissue, and nervous tissue. Each tissue has unique characteristics that differentiate them from one another. Epithelial tissue covers the surface of the body, connective tissue adds support and structure to the body, muscular tissue contracts to allow movement, and nervous tissue controls the organs (Hoehn & Marieb, 2007, p. 118).
In the twentieth century, technology is at an all time high in the world. This technology includes research, stock market shares, computers, medical advances, and a vast variety of other things. Among the advanced technology is a break through of computer use. Almost everyone at sometime in their day is using a computer for one task or another. Computers have taken the world and reshaped the possibilities of ideas and dreams in the past decade. Millions of people are using a computer daily according to

The nervous system’s main function is to coordinate all of the activities in the body. The main organs are the cerebellum, which controls and coordinates movement. The cerebrum, is the center for conscious thought, learning, and memory. The last main organ is the brain stem. The brain stem keeps the automatic systems in your body working. Problems of the nervous system include, epilepsy, Alzheimer’s, and multiple sclerosis. You can care for your nervous system by wearing a seatbelt, wearing a helmet, and by not using drugs or alcohol. Something very confusing about the nervous system is that the left side of human brain controls the right side of the body and the right side of the brain controls the left side of the body!
The roles of the circulatory and respiratory system both carry important responsibilities and are essential in their jobs to the human body. The circulatory system is one, if not the, most important system in the human body. The circulatory system is made up of the heart, blood, and blood vessels. Within the blood vessels, there are three types: arteries, veins, and capillaries. The heart is an organ made up of cardiac muscle that has a role similar to a pump. When the muscles in the heart contract, it pumps fresh blood away from the heart, through a main artery called the aorta, and to the organs and cells of the body. Nutrients and oxygen then enter the cells through diffusion of the tissues. The respiratory system transports oxygen to the circulatory system. When transporting oxygen to the circulatory system, this will in turn transport oxygen to the rest of the cells in the body. Aside from transporting oxygen to the body, the respiratory system also plays a role in the removal of carbon dioxide and other contaminants in the body. These two systems effectively and efficiently work together in order to supply the body with oxygen and remove carbon dioxide and any other
