Answer:
The aorta (the main blood supplier to the body) branches off into two main coronary blood vessels (also called arteries). These coronary arteries branch off into smaller arteries, which supply oxygen-rich blood to the entire heart muscle. The right coronary artery supplies blood mainly to the right side of the heart.

Answer:
<em>His decreased residual volume and decreased lung compliance contribute to his altered ventilation.
</em>
Explanation:
Pneumoconioses are distinguished by reduced residual volume and impaired compliance with the lungs.
Pneumoconiosis involves asbestosis, silicosis, and the pneumoconiosis (CWP) of coal workers.
The most prevalent mineral dusts proven to cause pneumoconiosis in the workplace are asbestos, silica (rock and sand dust), and coal dust.
Cough and shortness of breath are by far the most common symptoms of pneumoconiosis. The threat is usually greater when people are exposed to high levels and/or long periods of time from mineral dusts.
One risk factor is the insufficient or inconsistent usage of personal protective equipment (PPE) such as respirators (specially designed breathing masks), as avoiding inhalation of dusts would also avoid pneumoconiosis.
The difference between arteriosclerosis and atherosclerosis is that:
Arteriosclerosis is the hardening of the arteries in general.
Atherosclerosis is the hardening of the arteries via plaque build-up.
Generally, arteriosclerosis is due to "old age" but it's dangerous because there is no longer elasticity within the arteries. This can cause lack of blood flow. Atherosclerosis is dangerous the build up of fatty deposits can come loose and then lodge within a smaller vessel in the heart and the lungs. This is the common cause of a heart attack or a pulmonary embolism.
