human body system essay

The human body is made up of several systems : the circulatory system which circulates blood around the body via the heart, arteries and veins, delivering oxygen and nutrients to organs , the digestive system which consist of the mechanical and chemical processes that provide nutrients , the endocrine system which provides chemical communications within the body using hormones , the exocrine system consisting of skin, hair, nails, sweat and other exocrine glands , the immune system which defends

Not only are there damages to the immune system of the human body, but the musculoskeletal system is also at a very large risk for injury, even from the seat of a chair. German Researcher, T. Hettinger, “analyzed statistics on sick leave and found that musculoskeletal problems among administrative workers were higher than in any other industrial sector, and similar to those in construction, metal industry and transport” (Cranz, 2000, p. 98). This is saying that people who are working office jobs

The human liver is one of the most important organs in the human body. It has over 500 functions and is able to regenerate its cells. The liver, being an important part of the digestive system, functions to digest fats, filter drugs and poisons, store nutrients like vitamin A,D,E,K, and B12, secrete bile, and remove excess glucose from the body and store it until it is needed. Other functions of the liver include synthesizing proteins, production and regulation of chemicals such as globin (one

The human body is a complex system that is composed of billions of cells, undergoing growth, division and death in an orderly fashion on a daily basis. When this process occurs in an abnormal manner, the outcome is typically referred to as a tumor. In today’s world, tumor is a term that is commonly heard throughout the world. Also referred to as neoplasm, a tumor is an abnormal growth of tissue resulting from the rapid cell division due to some form of mutation (Cooper). They are classified into

Human body system communication is highly important for us to function properly. All the systems in the human body are essential to our survival and good health. If you take away the purpose of just one of these body systems our whole body will not work thoroughly. Nervous system, endocrine respiratory, circulatory, immune, digestive, excretory, skeletal, muscular, and the reproductive systems are all examples of different system in the human body. They all work jointly for us to move, dance, eat

There are eleven systems in the human body which one of them is known as the nervous system. Like most systems in the human body, the nervous system is composed of organs such as the brain, spinal cord, nerves and ganglia. The nervous system has been known to be the bodys primary communication and control system. The brain which is principally the main organ of the nervous system, is the center of all mental activity. These activities include thought, learning, and memory. It is also the most complex

The Human skeletal system The skeletal system is an important system of the human body, consisting of all bones, joints and other connective tissues. There are approximately 206 individual bones found in an adult human body. These bones are divided into two main groups called the axial skeleton and appendicular skeleton. The axial skeleton is made up of 80 bones whereas appendicular skeleton is made up of 126 bones. The skeletal system mainly consists of all bones and joints. Joints can be defined

and Report: Module 1 The respiratory system is a very important organ system in the human body. Its purpose is to transport oxygen to the blood where it can then move through the bloodstream to oxygenate all parts of the human body. The organs in the respiratory system consist of the nasal cavity, pharynx, larynx, trachea, bronchi, and lungs. Each organ plays an important role in respiration. The nasal cavity is the organ through which oxygen enters the body. This is the most superiorly and superficially

recipient; the organ will not cause any rejection. The body can reject the transplanted organ; as a result the body’s immune system will not accept the organ which has been transplanted; therefore it can have an effect on the organ that has been transplanted which is possible. The immunosuppressant drug is needed if the organ does reject the human body; the immunosuppressant drugs acts as an anti-rejection drug which is needed to protect the body from the organ that has been transplanted to reduce the

Human Body System Interaction . All the systems in the human body are vital to our survival and well-being. If you take away the functions of just one of these systems our whole body will cease to work properly. The main systems of the human body are the nervous, endocrine respiratory, circulatory, immune, digestive, excretory, skeletal, muscular, and the reproductive systems. They all work together in harmony and unison to keep us alive. The nervous and endocrine systems are what control
