The bronchial tubes lead directly into the lungs where the tube then again divide into many smaller tubes called bronchioles. Bronchioles then connect to small sacs known as alveoli. Alveoli are responsible for exchanging oxygen into carbon dioxide. Inhaled oxygen passes into the alveoli and then diffuses through the capillaries then into the atrial blood. Meanwhile the waste rich blood from the veins then release carbon dioxide into the alveoli.
The respiratory system is made up of the organs and tissues in your body that help you breathe. The goal of breathing is to deliver oxygen to the body and take away carbon dioxide, a waste product that can be deadly if allowed to accumulate. The cells of the human body require a constant stream of oxygen to stay alive. The body needs oxygen to provide energy and growth to body cells. The respiratory system resides in the upper abdomen and chest area where the oxygen comes in through the nose, through inhalation, and is processed by the lungs.
First of all, air is breathed into the body via the mouth and the nose. The air travels through the voice box (pharynx) down to the windpipe (trachea) and then through the bronchi into the lungs. The Carbon dioxide which is not needed is therefore required to be exhaled. This happens in a reverse process. However, the air taken in... ... middle of paper ... ...gs compared to that of the surrounding blood.
The veins supply the deoxygenated blood from the body to the right side of heart. Then the heart pumps it back to the lungs, where it absorbs more oxygen. Then the oxygen contained blood returns to the left side of your heart and then it pumps it out to the res... ... middle of paper ... ...ave large diameter to give least flow resistance. It has valves to prevent low pressure blood flowing backwards. Circulation of blood There are two types of circulatory systems which are pulmonary and systemic.
The alveoli are where the gas exchange takes place. The air sacs are surrounded by blood vessels that connect to the heart. The ones that link to the pulmonary arteries carry deoxygenated blood that needs to be refreshed.... ... middle of paper ... ... When you take part in certain exercises (like biking, running, or swimming, for example), your lungs require more air to give your cells the extra oxygen they need. As you breathe more deeply and take in more air, your lungs become stronger and better at supplying your body with the air it needs to succeed.
The alveolar wall is a thin membrane to allow gasses to pass through. The level of oxygen in the blood is lower than the oxygen level in the alveolar gas which creates a pressure difference making the oxygen move into the blood. The co2 in the blood is higher in the blood than in the air so the co2 trav... ... middle of paper ... ...em works interdependently with the cardiovascular system to be able to deliver nutrients absorbed through digestion to where it is needed in the body. The small intestine walls have thin epithelial layer and then have many capillaries for easy absorption of nutrients into the blood stream. (Turtle, Edd 2004) The integumentary system is made up of the skin, hair, nails and various glands.
(Lymph Transport and Immunity, McGraw Hill) Overall, the lymphatic system is crucial in enabling the body to remain healthy and fight off infection. By absorbing fats and trapping antigens, it helps to keep the body healthy and disease-free. Without the lymphatic system, people would not be able to survive and would be full of disease. In order to survive no matter if you a human or a dog, a healthy lymphatic system is necessary to the survival of these advanced species.
In the lungs, oxygen is taken into the body and carbon dioxide is breathed out. The red blood cells collect oxygen from the lungs and deliver it to other cells in our body and they also pick up the waste from the other cells (Carbon Dioxide) and bring it back to the lungs to get exhaled. The diaphragm is not part of where the air travels, but it is used to air in and out of the lungs. The diaphragm is a muscle that moves, causing a change in air pressure. When you breathe out, the diaphragm moves upward, which decreases the volume of the lungs, causing high pressure.
Supply oxygen to the body and to eliminate carbon dioxide The upper respiratory tract consist of the Nose, larynx, pharynx and trachea 1. Nose – provides airway for respiration and filters air. Detects odor 2. Larynx- the voice box, main functions are • Speech. • Breathing.
Also the person can wear a mask when using paint, paint remover, varnish, or other substances with strong fumes. This will help protect the lungs. Wash the hands often to limit the exposure to germs and bacteria. The doctor also may advise to get a yearly flu shot and a pneumonia vaccine. # Conclusion: The respiratory system is a very important system in our body, so we have to take care of our system and provide a healthy environment to make it work probably.
