Inflammation of the lungs and bronchial tubes are also common causes of shortness of breath, as is injury to the respiratory tract caused by smoking or other toxins. Shortness of breath may occur with injury to the lungs, such as a collapsed lung (pneumothorax).
In the United States, pea soup without qualification usually means a perfectly smooth puree. Split Pea Soup is a slightly thinner soup with visible peas, pieces of ham or other pork, and vegetables (most commonly carrots) and is usually made from dried, green split peas.
Shelling peas, also known as the garden pea or English pea, have tough, fibrous pods that must be removed prior to consumption. Each pod usually contains several peas. Harvest shelling peas as the peas mature and reach the size of the planted seed. As the peas approach maturity, sample daily and be ready to pick when they are full size but still tender and sweet. Don't wait too long.
