Functional Consequences of Age-Related Changes Affecting Respiratory Function
- Upper airway changes: calcification of cartilage, altered neuromuscular function and reflexes.
- Increased anteroposterior diameter, chest wall stiffness, weakened muscles and diaphragm.
- Enlargement of the alveoli, thinning of alveolar walls, diminished number of capillaries.
Decreased elastic recoil and early airway closure.
- Tidal volume unchanged or slightly diminished, increased residual volume, decreased vital capacity.

∙ 11y agoThe lungs and respiratory passageways of a person who has breathed only clean air are pinker and can exchange gases much more efficiently as the years pass than can the respiratory system of a person who has breathed polluted air and smoked for many years. Other factors such as exposure to foul air can lead to the development of chronic bronchitis, emphysema, and/or lung cancer. Long-term exposure to particulates in the workplace can also raise the risk of developing these conditions.

Where in the respiratory system does gas change occur?
in the alveoli
Which organs cause inhalation and exhalation to occur?
Respiratory system.
Where in the respiratory system does gas exhcange occur?
Gas exchange occurs in the alveoli in the respiratory system. The thin-walled structures allow diffusion of gases into and out of the capillaries.
19 In what part of the respiratory system does the exchange of oxygen and carbon dioxide occur?
Lungs
Where do goblet cells occur in the respiratory system?
Goblet cells are in the respiratory epithelium, which lines the airways from the pharynx down into the lungs. They secrete mucous.
What respiratory system changes occur when someone quits smoking?
cilia regain normal function
What are disease that occur in the respiratory system?
Asthma Bronchitis Lungs cancer! Emphysema , Cough etc.
What are the normal changes that occur in the respiratory system during exercise?
respiratory system change with more exercise because it is related to our cardiovascular and respiratory system.when we do exercise our heart rate increases cardiac output increases and oxygen is more utilizing and more energy is required.These all cause effect on respiratory system
Which one of the following conditions is least likely to occur if the cilia in your respiratory system are damaged?
Multiple sclerosis
How can a person's lifestyle affect the performance of the respiratory and circulatory systems?
Smoking, lack of exercise, lack of attention to asthma, and exposure to irritants such as dust can all affect the performance of the respiratory and circulatory systems.
Where does oxygen transfer during the transition between the respiratory and circulatory system occur?
By diffusion across a capillary wall.
Where does gas exchange occur in the human respiratory system?
Gas exchange does not occur in the respiratory tract, it occurs in the alveoli.
