Can affect any farmer who works with wet hay or other moldy dust. Small farmers who have to directly thresh and handle their hay are most at risk, as are those living in cold and humid areas where damp weather is common.
our lung contracts and carbon di oxide goes out
The lung doesn't relax, it is controlled by the diaphragm When it relaxes the volume of the lungs decrease during expiration When it contracts the volume of the lungs increases during inhilation
When you inhale, your diaphragm contracts dropping down causing negative pressure in your thoracic cavity(lung area) so that air can circulate through the lungs.
Your diaphragm contracts, which forces your lung to draw in air. Hiccups are caused when your body is trying too hard to regulate your breathing, so it accidentally messes itself up. The actual hiccup is your body trying to get back on track.
When the diaphragm contracts, it moves downward, increasing the volume of the thoracic cavity. This leads to a decrease in intraalveolar pressure, causing air to flow in from the atmosphere to equalize the pressure, resulting in inhalation.

when right ventricle contracts the blood goes to "lung" and when left ventricle contracts the blood goes to all part of our body. Correct, more specifically, throught the pulmonary artery on the right, and through the arota on the left side of the heart into systemic circulation.
Because in its original, relaxed state, the lung is still hollow and does not collapse on itself. It only expands, and then contracts to its original state. It does not shut tight.
From the right ventricle blood flows to the pulmonary artery then to the lung to get oxygenated then to the pulmonary vein into the left auricle to the left ventricle the to the aorta then to the rest of the body.
In a constructed lung model, the diaphragm typically represents the muscle that facilitates breathing, while the balloon or elastic bag simulates the lung tissue that expands and contracts with airflow. The tube or straw represents the trachea and bronchi, allowing air to flow in and out of the model. Lastly, any additional components, such as a container for water, may illustrate the pleural cavity and the effects of pressure changes during respiration.
No. CME Group has introduced "broiler chicken" futures in the past and has always failed, because the chicken industry is extremely integrated--farmers grow under contract to processors.
