Respiratory System
- Components
- Nasal Passage
- Air enters the body through the nasal passage during normal breathing
- Here air is moistened, warmed and filtered
- Air enters the body through the nasal passage during normal breathing
- Trachea
- Air passes down the trachea to the lungs
- The trachea is a flexible tube and is stiffened by rings of cartilage
- Air passes down the trachea to the lungs
- Bronhci
- The trachea gets split into two brochi
- Each of the bronchi go to a side of the lungs
- The bronchi are two major air tubes
- The trachea gets split into two brochi
- Bronchioles
- The bronchi splits into smaller tubes called bronchioles that distributes air to the alveoli
- The bronchi splits into smaller tubes called bronchioles that distributes air to the alveoli
- Alveoil
- Air eventually reaches millions of tiny air sacks called alveoli
- This is where gases exchange happens because the walls are so thin
- Air eventually reaches millions of tiny air sacks called alveoli
- Diaphragm
- Contracts when breathing. Pulls downwards to increase the volume of air in chest
- Contracts when breathing. Pulls downwards to increase the volume of air in chest
- Nasal Passage
- Reason for the system
- An efficient respiratory system allows more oxygen to reach the blood and consequently the
muscle. This is very important because the harder and longer the physical activity, the more
oxygen is needed to keep the muscles working and the more carbon dioxide produced
- An efficient respiratory system allows more oxygen to reach the blood and consequently the
muscle. This is very important because the harder and longer the physical activity, the more
oxygen is needed to keep the muscles working and the more carbon dioxide produced
- Gas Exchange
- Blood cells
- The blood cells come in carrying carbon dioxide, and once gas exchange happens leaves with oxygen to fuel muscles
- The blood cells come in carrying carbon dioxide, and once gas exchange happens leaves with oxygen to fuel muscles
- Gases
- Oxygen is breathed in, swapped with carbon dioxide
- Carbon dioxide is then breathed out
- Carbon dioxide is then breathed out
- Oxygen is breathed in, swapped with carbon dioxide
- Blood cells
- Effects
- Long Term
- Smoking
- Increase cancer risk
- Cough and respiratory infections
- Increase chance of emphysema
- Slow destruction of air sacs
- Slow destruction of air sacs
- Increase chance of bronchitis
- Infection of main airways
- Infection of main airways
- Shortness of breath
- Increase cancer risk
- Exercise
- Strengthen intercostal and diaphragm muscles
- Increase number of alveoil
- Increase vital capacity
- Amount of air that can be forced in and out after a breath
- Amount of air that can be forced in and out after a breath
- Increase in oxygen delivered and carbon dioxide removed from the body
- Strengthen intercostal and diaphragm muscles
- Smoking
- Short term
- Smoking
- Paralyses Cilia
- Tiny hairs that sweep debris away from the lungs or nasal cavities
- Tiny hairs that sweep debris away from the lungs or nasal cavities
- Coughs and colds
- Irritates throat
- Paralyses Cilia
- Exercise
- Increased breathing rate
- Increased tidal volume
- Amount of air breathed in and out the lungs in one breath
- Amount of air breathed in and out the lungs in one breath
- Increased breathing rate
- Smoking
- Long Term
