What is the ease with which the lungs can be expanded during breathing called?
The ease with which the lungs and thorax can expand is called "COMPLIANCE".
How breathing rate is affected by cigarette smoking?
Well when you moke basically you are filling your lungs with smoke and causes oxygen to decrease in your lungs and you to breathe slower.
What causes the air pressure in your lungs to decrease and make you inhale?
When you inhale, oxygen fills your lungs. Next the oxygen diffuses out of your lungs into your bloodstream. The diffusion of oxygen from the lungs causes less pressure in your lungs signaling your brain that you need to inhale.
What enables us to breathe?
The contraction of the diaphragm causes it to move down, increasing the volume of the thoracic cavity. This movement and volume change decrease the pressure in the lungs, and air rushes in.
What is the term when lungs and chest wall expand easily?
high compliance
Do normal lungs have high or low compliance?
Tuberculosis is a disease in it's own right and can effect many parts of the body including the lungs. It is not cancer and normally much easier to cure.
Increasing the size of the thoracic cavity causes?
inhalation/inhale it also causes a decrease pressure in thoraces cavity and pleural cavity
What muscle allows the lungs to fill the lungs with air?
The diaphragm. (located beneath the lungs) When it contracts it moves down, thus expanding the volume of the lungs. This causes the pressure in the lungs to decrease and air to flow in to the lungs. (pressure is inversely proportional volume- Boyle's law) This is inhaling. When the diaphragm relaxes it moves back up, decreasing the volume of the lungs and increasing the pressure which forces the air out. This is exhalation.
How is smoking harmful to your lungs?
Your lungs are the reasons you body has Oxygen. In your lungs, we do produce mucus, which we cough up because of the cilia in our lungs. Smoking causes this cilia to not move the mucus out of your lungs which in turn causes problems.
Why does vital capacity gradually decrease with age?
Vital capacity decreases with age due to changes in lung elasticity, chest wall compliance, and muscle strength. These changes can lead to a decrease in the ability of the lungs to stretch and fill with air, resulting in a reduced amount of air that can be exhaled after a maximal inhalation. Additionally, age-related factors such as decreased respiratory muscle strength and changes in lung structure can further contribute to the decline in vital capacity.
What two gases increase or decrease during inhlaing and exhaling?
Oxygen and carbon dioxide increase and decrease in the lungs.
What is the mode of respiration in chicken?
The bird's respiratory system consists of paired lungs, which contain static structures with surfaces for gas exchange, and connected air sacs, which expand and contract causing air to move through the static lungs.
