Unit 5, Task 2- Gross structure of all main systems P3 Cardiovascular system- The main functions of this system are to transport nutrients, gases and waste products around the body, to protect the body from infection and blood loss, to help the body maintain a constant body temperature and to help maintain fluid balance within the body. The cardiovascular system works in conjunction with the respiratory system to deliver oxygen to the tissues of the body and remove carbon dioxide. Nutrients like glucose from digested carbohydrate are being delivered from the digestive tract to the muscles and organs that require them for energy. Hormones from endocrine glands are transported by the cardiovascular system to their target organs, and waste…show more content…
This system includes your airways, your lungs and the blood vessels and muscles attached to them that work together so you can breathe. The respiratory system's function is to supply oxygen to all the parts of your body. It achieves this through breathing: inhaling oxygen-rich air and exhaling air filled with carbon dioxide, which is a waste gas. The respiratory system is made up of airways these are your nose, mouth, voice box, windpipe and bronchial tubes, and the lungs and the muscles and blood vessels connected to them. Your respiratory system works by you breathing air in through your nose and mouth, which wet and warm the air so it wont irritate your lungs. After that the air travels through your voice box, down your windpipe and then through bronchial tubes into your lungs. Cilia in your airways entrap foreign particles and germs to filter the air that you breathe. You then cough or sneeze the particles out of your body. The main components of the respiratory system are the nose (moistens air, filters air and warms air), larynx, pharynx, trachea (Connects the external respiratory organs with the lungs), bronchi (Components essential for external respiration), bronchioles (Each terminal bronchiole conducts air to an acinus in the lung), pleura, alveoli, and the diaphragm (contracts with each inspiration, becoming flattened downwards and increasing the volume of the thoracic
