Answer:
I believe it;s the difference in pressure
Explanation:
This is caused by the diaphragm contracting and therefore expanding the thoracic cavity. This increase in volume causes a decrease in pressure.
To obtain a scan using the positron emission tomography technique, a patient is injected with (or ingests) a low and harmless dose of a short-lived radioactive glucose.
<h3>
What is Positron emission tomography?</h3>
This refers to a type of imaging technique which employs the use of radioactive substances in other to measure the metabolic activity of the cells of body tissues.
A scan using this technique is obtained by injecting the patient with a low and harmless dose of a short-lived radioactive glucose so that a picture of where the glucose being used in the body is visible and helps to detect cancerous cells etc.

Pharmacodynamics is the study of the biochemical and physiologic effects of drugs.
Answer:
Rickets disease.
Explanation:
Rickets disease occurs when there is a mineralization deficit of the extracellular bone matrix; as a result, the bones are soft, and they deform easily. The X-rays show thick epiphyseal plates because it is hyaline cartilage that should be calcified to become a bone. As there is a deficit of vitamin D, the mineralization of the plate can not be done, making bone is flexible and deformable.
The main cause for Rickets disease is a diet with low intakes of calcium and vitamin D, and poor exposition to the sun, which is the best way to produce vitamin D. These two components are crucial for the mineralization of the bones.
Pulmonary embolism occurring in up to 3 in every 1,000 births is a major cause of death.
One of the pulmonary arteries in your lungs can get blocked, causing a pulmonary embolism. The majority of the time, blood clots from deep leg veins or, rarely, veins in other parts of the body that go to the lungs cause pulmonary embolism (deep vein thrombosis).
Pulmonary embolism, which occurs when blood clots obstruct the flow of blood to the lungs, can be fatal. But the danger of dying is significantly decreased with quick treatment. By taking precautions to avoid leg blood clots, you can lessen your risk of developing pulmonary embolism.
