Food poisoning occurs when you eat food contaminated with bacteria or other toxins. Symptoms include diarrhea, vomiting, and stomach cramps, and generally start 4 to 36 hours after eating contaminated food. While food poisoning is often caused by bacteria, it can also result from eating poisonous plants (some mushrooms, for instance) and animals (pufferfish). Food poisoning is especially common during summer when food may not be kept cold enough to prevent bacteria from growing.
When you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. This increases the space in your chest cavity, into which your lungs expand. The intercostal muscles between your ribs also help enlarge the chest cavity. They contract to pull your rib cage both upward and outward when you inhale. As your lungs expand, air is sucked in through your nose or mouth.
Your lungs sit in your chest, protected by your rib cage. They are large and take up most of the space in your chest cavity, along with your heart. Below your lungs youâll find the diaphragm, which is the large muscle that works with your lungs to help you breathe in (inhale) and out (exhale). Even though you canât see your lungs, itâs very easy to feel them at work. Simply put your hands on your chest and take a few deep breaths. You can feel your chest expand as you inhale and return to its normal size when you exhale.
