Here's something I was just thinking about... When you try your best to do something good...but you feel like you messed it up? The time you try to help everyone you can because you have such a big heart. But do you EVER get asked "what can I help YOU with?" The time you spend crying just because you feel like nobody is their for you? The time crying because you asked yourself, "Why do people think this is the answer?" When you think of how bad this world is...but there is NOTHING you can do about it. You just think...why do I have to live in a world full of hate... people pulling each other down because that's OK? Girls, starving themselves to be what society things is "good enough". WHEN WILL WE STOP? How many more have to go before we realize we are ALL good enough! But you then think again...am I part of the problem?

Im honestly in a low...but I ALWAYS get through them. I'm not going to do anything to myself AT ALL. (I know some will ask that) This is just a thought of mine. Who can relate? I am always here to talk...so if you need something ASK ME! (and just for the record...im 13)

Containing a negative consequence for the stability of the social system

The primary function of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. the respiratory system does this through breathing. when we breathe, we inhale oxygen and exhale carbon dioxide. this exchange of gases is the respiratory system's means of getting oxygen to the blood.respiration is achieved through the mouth, nose, trachea, lungs, and diaphragm. oxygen enters the respiratory system through the mouth and the nose. the oxygen then passes through the larynx (where speech sounds are produced) and the trachea which is a tube that enters the chest cavity. in the chest cavity, the trachea splits into two smaller tubes called the bronchi. each bronchus then divides again forming the bronchial tubes. the bronchial tubes lead directly into the lungs where they divide into many smaller tubes which connect to tiny sacs called alveoli. the average adult's lungs contain about 600 million of these spongy, air-filled sacs that are surrounded by capillaries. the inhaled oxygen passes into the alveoli and then diffuses through the capillaries into the arterial blood. meanwhile, the waste-rich blood from the veins releases its carbon dioxide into the alveoli. the carbon dioxide follows the same path out of the lungs when you exhale.the diaphragm's job is to pump the carbon dioxide out of the lungs and pull the oxygen into the lungs. the diaphragm is a sheet of muscles that lies across the bottom of the chest cavity. as the diaphragm contracts and relaxes, breathing takes place. when the diaphragm contracts, oxygen is pulled into the lungs. when the diaphragm relaxes, carbon dioxide is pumped out of the lungs. write one paragraph (at least 6 sentences) describing the path of oxygen through the respiratory system. also include why this "order of operations" is the way it is!
