Significance of Oxygen in Animals
Breathing is very important for animals. As humans, we need it to survive. In order for this process to occur, we use certain organs such as our lungs and heart. Inside our organs, cellular respiration takes place in the mitochondria of our cells. This is when the chemical energy that we obtain from food molecules is released and converted to the form of ATP, which is the the energy we need. Molecules like these are transported through the process of diffusion, the movement of molecule from a high to low concentration. As a result of all of this, we release a waste called CO2. This is given to plants and in exchange plants give us oxygen as their waste.
Body Structurers
The traveling of our oxygen consist of particular body structures. These are known as the trachea, alveoli, and bronchi. The trachea, commonly known as the windpipe, is the tube that connects the nose, larynx (voice box), and bronchi (lung cavities). The alveoli, or small-balloons, aid the the process of inhalation and deflation of oxygen in the lungs. The bronchi are the main passageway for the lungs and is used once air travels through the larynx and trachea. All of these structures aid in the movement of oxygen through our body.
Respiration in Scorpions
The process for breathing in scorpions is very different from the way we do. They have spiracles that allow air into their trachea.Their inflow and outflow of air is controlled by muscles called the dorso-ventrual and atrial. When these muscles contract, their lungs are compressed causing the air to be released out of the atrial chamber. A scorpion consist of four "book" lungs and each lung consist of two parts.
