The more active you are, your heart and lungs work harder to deliver oxygen to your muscles, according to the American Lung Association. This makes your heart and lungs stronger and improves your ...
It’s important to pay attention to the signs of lung disease and any symptoms that indicate your lungs might not be healthy, as early detection can go a long way in helping to manage and treat ...
Studies show that keeping your head at the appropriate height—about 2 inches (or 5 centimeters) off the bed—helps air flow into the lungs and stabilizes your respiratory function. However ...
The control of ventilation is the physiological mechanisms involved in the control of breathing, which is the movement of air into and out of the lungs. Ventilation facilitates respiration. Respiration refers to the utilization of oxygen and balancing of carbon dioxide by the body as a whole, or by individual cells in cellular respiration. [1]
The cells in the respiratory epithelium are of five main types: a) ciliated cells, b) goblet cells, c) brush cells, d) airway basal cells, and e) small granule cells (NDES) [6] Goblet cells become increasingly fewer further down the respiratory tree until they are absent in the terminal bronchioles; club cells take over their role to some extent here.

The lungs are the largest organs in the lower respiratory tract. The lungs are suspended within the pleural cavity of the thorax. The pleurae are two thin membranes, one cell layer thick, which surround the lungs. The inner (visceral pleura) covers the lungs and the outer (parietal pleura) lines the inner surface of the chest wall. This ...
Most of us know more people who’ve had it than not, and chances are you’ve had it yourself at least once. What may still take you by surprise, though, are the side effects that can linger for ...
The respiratory airway secretory cell (RAS), is found in the lungs of humans and some other mammals, notably ferrets. They are facultative progenitors that have important functional roles in maintaining lung airway health. Their role in maintaining the gas-exchange compartment of the lung is critical and they may be altered in chronic lung disease.
