the lung capacity will lessen and the veins and tubes connecting ect will get thinner because of the tar build up therefore they can find it harder to breath because they cannot get as much oxygen to the lungs thank youu x
There are many reasons that could increase or decrease vital capacity in a person. Respiratory conditions are a major factor in how much air a person can take in.
Emphysema's effect on vital capacity increases as the disease progresses. Emphysema is a chronic obstructive pulmonary disorder (COPD) which obstructs the passage of air out of the lungs. As a person exhales with emphysema, the airways close prematurely which reduces the exhalation volume thus reducing vital capacity.
Smoking can weaken the lungs and reduce breathing capacity. Also smoking can reduce oxygen level of blood thus blood can not carry enough oxygen to the necessary organ.
Four factors that can affect the vital capacity of a person are age (vital capacity decreases with age), gender (males tend to have higher vital capacity than females), height (taller individuals usually have higher vital capacity), and physical fitness level (regular exercise can increase vital capacity).
Vital capacity is a term which refers to the maximum volume someone can breathe in his lungs [ the max volume of air inhaled after a max exhalation]. It depends on many factors. How fit someone is, smoking, obesity, height, sex, body size and the posture of the body [when someone lies his vital capacity is less than standing]. Also when playing a flute instrument you'll increase your vital capacity,

the vital capacity of lungs is 3.5 liters to 4.5 litres
vital lung capacity is how much air remains in your lungs after you exhale
My vital capacity is 1650cc (Yes, it's very low, but I'm twelve and I'm small). cc is used to measure vital capacity.
bigger body surface area = bigger vital capacity
Smoking adversely affects spirometry results by causing a decline in lung function, evidenced by reduced forced expiratory volume in one second (FEV1) and forced vital capacity (FVC). It can lead to obstructive patterns, such as decreased FEV1/FVC ratios, indicating conditions like chronic obstructive pulmonary disease (COPD). Additionally, smoking can cause airway inflammation and increased resistance, further impairing respiratory efficiency. Overall, spirometry reflects the detrimental impact of smoking on pulmonary health.
