Moving air breathed in and out creates sound. Trachea – Filters air we breathe and branches into the Bronchi. Bronchi – Two air tubes that branch off the Trachea and carry air directly into the lungs. Bronchioles – Branches from the Bronchi, which ends, contain the alveoli. Alveoli – Very small air sacs that are the destination of air breathed in.
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.
What is the cough reflex? Describe the process that Cari’s respiratory system is using to clear her lungs by coughing. A cough reflex is a long-drawn and deep inhalation followed by a complete closure of the glottis, which results in a strong exhalation that suddenly pushes the glottis open and sends a blast of air through the upper respiratory passages. This process is clearing her lungs by forcing foreign bodies out of the larynx, trachea and epiglottis. C. Which structures found in the terminal bronchioles and alveoli normally would protect Cari’s lungs from infectious pathogens and particulate matter?
This path will divide into even smaller branches that are known as bronchioles. At the end of the bronchioles are very small air sacs called alveoli. They deflate during exhalation and inflate when you inhale. The gas exchange of oxygen cycles through the lungs and then the blood stream as the walls of the alveoli shares the same walls with capillaries making the exchange of oxygen for carbon dioxide between the two very easy. The oxygen molecules attach to the red blood cells as the red blood cells move towards the heart, as the carbon dioxide is evacuated from the body by the exhale.
The first major muscle movement occurs when food or liquid is swallowed. Although you are able to start swallowing by choice, once the swallow begins, it becomes involuntary and proceeds under the control of the nerves. Swallowed food is pushed into the oesophagus, which connects the throat above with the stomach below. At the junction of the oesophagus and stomach, there is a ring like muscle, called the lower oesophageal sphincter, closing the passage between the two organs. As food
The air which we breathe in which is kept in the lungs, is the transferred into blood. The blood then goes around the heart, which then pumps oxygenated blood from lungs back into the body. The 2 systems also work together in order to get rid of carbon dioxide which is there as a metabolic waste product. D1
The thick layer of mucus protects intestinal walls from acids and gases released by bacteria. In the large intestine, remaining water from digestion is absorbed by the mucosal cells through
Make sure the rubber stopper is securely in place since gas can easily leak out. Collecting the gaseous product: Prepare the gas collection bottle by positioning the bottle so that its mouth is. directly over the hole at the bottom of the trough; this is where the gas will enter the bottle. After the reaction, slide a square of glass over the mouth of the bottle while the bottle is still under water. Keeping the glass fixed to the mouth, raise the collection bottle and invert.
It is then secreted within the small intestine where it helps to break down ethanol, fats and other acidic wastes including ammonia, into harmless substances. Large Intestine-The large intestine collects waste from throughout the body. It extracts any remaining usable water and then removes solid waste. At about 5 feet long, it transports the wastes through the tubes to be excreted. Skin-Skin extracts sweat through sweat glands throughout the body.
Fibre and other digested foods as they pass through the body do not change very much until it reaches the large intestine, the process of excretion after the reaching of the large intestine depends on the type of Fibre is consumed. There are two types of Fibre: soluble Fibre and insoluble Fibre. Soluble Fibre is a Fibre that is quite helpful to nutrients, as it makes energy from consumed substances leave the body at a smoother and steadier pace. Preventing tiredness, hunger pains, lack of energy and strength. Soluble Fibre when passing through the large intestine absorbs the water turning the faecal matter much softer, allowing the waste to pass through the body quickly.
