The Function and Mechanics of the Digestive System SCI/241 The Function and Mechanics of the Digestive System My 4 year old daughter asked me‚ “Mommy‚ how does food go to my stomach?” It is really weird the questions children ask but I had to explain. In this paper I will explain the function and mechanics of the digestive system. The body ’s method of taking the food we eat and breaking it down to obtain vital nutrients that will allow us to live and be healthy is digestion. According

OF THE RESPIRATORY SYSTEM The primary function of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The respiratory system does this through breathing. When we breathe‚ we inhale oxygen and exhale carbon dioxide. This exchange of gases is the respiratory system’s means of getting oxygen to the blood. Respiration is achieved through the mouth‚ nose‚ trachea‚ lungs‚ and diaphragm. Oxygen enters the respiratory system through

What is the entire process of gas exchange between atmosphere and body cells called? The entire process of exchanging gases between the atmosphere and body cells is called respiration. 3. What is the waste product of cells? The two main waste products of respiration are Water (H2O) and Carbon Dioxide

The respiratory system carries out gas exchange; major organs in the system include: the nose‚ pharynx‚ larynx‚ trachea‚ bronchi‚ and lungs. The major function of the respiratory system is to supply the body with oxygen and dispose of carbon dioxide. In order for this to happen‚ at least four events called respiration must occur. The first is the pulmonary ventilation. The air must move in and out of the lungs so that the gases in the alveoli are continuously refreshed. This process is better known

rib cage moves down and in diaphragm relaxes. The lungs are the main part of the respiratory system. The respiration system produces energy from taking oxygen and produces carbon dioxide which is takes place in the cells. The oxygen goes to the mitochondria inside the cell where it combines with sugar to create energy and produce carbon dioxide and water. The respiratory system connects to circulatory the system because blood goes to the lungs and to picks up oxygen and releases carbon dioxide

Dissections help researchers get a 3-dimensional picture of how the systems of a body work together. Now you’ll have the opportunity to see how the respiratory‚ digestive and circulatory system are arranged spatially.

Asthma: Disease of the respiratory system Breathing‚ the act of inhaling and exhaling of air. Oddly enough this process is an absolute necessity for life and yet we do not control it. There are two systems involved in our ability to breathe one is the parasympathetic nervous system and the other is the respiratory system. The parasympathetic nervous system controls the body ’s unconscious actions that are necessary to live such as the beating of the heart. The Respiratory system mainly consists of

Aging is something that continuously happens throughout life‚ which produces a lot of changes throughout the body. With that being said‚ many changes throughout the body affect the respiratory system. As individuals age‚ bones of the body become thin‚ weak‚ and change shape. The ribcage is affected by this change and can alter a person’s breathing as it becomes unable to expand and contract the way it used to. Muscles in the body also become weak. If the muscle that supports breathing‚ called the
