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.
Alveoli. The epithelium of the alveoli, contains two main types of cells: 1. type I pneumocytes: large flattened cells - (95% of the total alveolar area) which present a very thin diffusion barrier for gases.They are connected to each other by tight junctions.2. type II pneumocytes (making up 5% of the total alveolar area, but 60% of total number of cells).lveoli.
