Remember, they have been blanched prior to freezing, so they are already partially cooked. I often roast frozen broccoli or Brussels sprouts in the morning, early, before work so I can take a roasted vegetable for lunch. I can just use a half bag of frozen broccoli, cauliflower, Brussels sprouts or green beans, and leave the rest frozen for another day or meal.
Water vapor is also excreted through the lungs, due to humidification of inspired air by the lung tissues. Molecules with a high affinity for hemoglobin, such as carbon monoxide, can be added to the blood in high concentrations. Red blood cells transit the alveolar capillaries in about 3/4 of a second.xygen moves from the alveoli (high oxygen concentration) to the blood (lower oxygen concentration). Conversely, carbon dioxide has a higher concentration in the blood than in the air. The oxygen first dissolves in the fluid in the interstitial tissues and diffuses into the blood.
Gas exchange in the lungs and in the alveoli is between the alveolar air and the blood in the pulmonary capillaries. This exchange is a result of increased concentration of oxygen, and a decrease of C02. This process of exchange is done through diffusion.uring inhalation or exhalation air is pulled towards or away from the lungs, by several cavities, tubes, and openings. The organs of the respiratory system make sure that oxygen enters our bodies and carbon dioxide leaves our bodies. The respiratory tract is the path of air from the nose to the lungs.
