The Respiratory System is crucial to every human being. Without it‚ we would cease to live outside of the womb. Let us begin by taking a look at the structure of the respiratory system and how vital it is to life. During inhalation or exhalation air is pulled towards or away from the lungs‚ by several cavities‚ tubes‚ and openings. The organs of the respiratory system make sure that oxygen enters our bodies and carbon dioxide leaves our bodies. The respiratory tract is the path of air from the

An overview of the nervous and endocrine systems‚ their functions and how together they regulate homeostasis The endocrine system is the internal system of the body that deals with chemical communication by means of hormones‚ the ductless glands that secrete the hormones‚ and those target cells that respond to hormones. The endocrine system functions in maintaining the basic functions of the body ranging from metabolism to growth. The endocrine system functions in long term behavior and works

The endocrine system is very dynamic and has ties to most‚ if not all of the other major systems of the body. It is responsible for production of hormones and the regulation of them as well. These hormones act as chemical messengers within the body. Through several differing mechanisms‚ they are able to trigger very specific responses in target cells or organs. This is what enables the endocrine system to guide growth‚ development‚ reproduction‚ and behavior‚ among many others as well.

It is also called as the oxygen delivery system for it is the system responsible in delivering the oxygen to all parts of the body. The process of breathing‚ the inhalation of oxygen and exhalation of carbon dioxide‚ is called respiration. Respiration can be described

The Lymphatic System And Immunity The cells‚ tissues‚ and organs of the lymphatic system play a central role in the body’s defenses against a variety of pathogens‚ or disease-causing organisms. Acts against environment hazards‚ various pathogens‚ and internal threats. Lymphocytes (primary cell) are vital to or overcoming infection and disease. Lymphocytes respond to invading pathogens‚ abnormal body cells‚ and foreign proteins. They act to eliminate these threats or render them harmless
