The cardiovascular system is made up of the heart and blood vessels‚ which are divided into arteries‚ veins and capillaries. The blood delivers nutrients and oxygen to the cells in the body. The arteries carry blood away from the heart and the veins carry it back to the heart. Capillaries are found in the muscles and the lungs‚ they have valves to stop the blood flowing backwards and this is also where gaseous exchange takes place. The heart works as a pump that pushes blood to the organs‚ tissues

A&P II Instructor: David Armoogam September 10‚ 2010 The respiratory system helps with breathing‚ inhaling and exhaling. The respiratory systems main function is to give oxygen to the body’s cells and get rid of the carbon dioxide the cells produce. Breathing would be impossible without the respiratory system‚ which includes the nose‚ throat‚ voice box‚ windpipe‚ and lungs. In this essay I plan on explaining how the respiratory system functions as well as its parts. The exchange of two gases called

After making a working model of the respiratory system students can connect what they read about the respiratory system with what they see. Prior Knowledge: Students have read aloud a respiratory system chapter from their science book‚ "Discovery Works" in class. Students should know the parts of the respiratory system and the basics of how it operates.

absorbed into the blood. There are two body systems that are involved in the getting the oxygen and energy into the blood‚ respiratory and digestive system. The role of a respiratory system goes through many steps before the oxygen gets into the blood. The first step is when the air enters the nose and mouth and travels down into through the pharynx‚ larynx and towards the trachea. After it pasts the trachea‚ the air will travel through two tubes that work towards the two lungs‚ the tubes are called

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

RESPIRATORY SYSTEM The respiratory system consists of all the organs involved in breathing. These include the nose‚ pharynx‚ larynx‚ trachea‚ bronchi and lungs. The respiratory system does two very important things: it brings oxygen into our bodies‚ which we need for our cells to live and function properly; and it helps us get rid of carbon dioxide‚ which is a waste product of cellular function. The nose‚ pharynx‚ larynx‚ trachea and bronchi all work like a system of pipes through which

Respiratory system: The respiratory system is a combination of the Circulatory and Pulmonary systems feeding oxygen and nutrients to cells all around the body. These systems allow oxygen to enter the body‚ and be circulated around the body at a varying rate. These two systems work in conjunction with each other and have various rates of operation that are usually in as close a correlation as possible. Circulatory System: The circulatory system’s primary responsibility is to circulate oxygenated

The Respiratory System The human respiratory system plays a very important part in our bodies. Without it‚ we wouldn’t be alive! We need air to move through our bodies at all times. Breathing‚ is a key necessity for life. Our respiratory system is made up of many organs that all work together. The goal of breathing is to deliver oxygen to the body and take away carbon dioxide. The respiratory system organs all work together‚ like a engine in a car‚ they all have a important role. Some

Exercise No. Respiratory System I. Introduction Oxygen is a very important element which our body needs. Without oxygen life is not possible without oxygen which helps in producing energies that our body cells need. But‚ how do we acquire this oxygen needed by the body? It is by the process called Respiration. Respiration is a process of taking in and out of air from the body. There are two kinds of respiration called cellular respiration and external respiration. Cellular respiration

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
