Gas exchange/respiratory system Overall purpose
The process of respiration is the exchange of oxygen and carbon dioxide between an organism and the environment. [1] The goal of the respiratory system is to achieve "cellular respiration". The exchange of gases, from carbon dioxide to oxygen. The process of cellular respiration, is the process in which the energy stored in glucose is used to make energy rich ATP. Cellular respiration is an important source of energy in the body. ATP is an energy-carrying molecule found in all organisms. It captures energy from broken down food molecules, it delivers energy to cells. The mitochondria receives the energy using it for the cell's needs. Because of the function of cellular respiration, as we inhale and exhale, oxygen is constantly being diffused into our blood, as waste (including carbon dioxide) exits our body.
All mammals have lungs, while other animals have gills or other system for obtaining oxygen, aiding in their respiration. [2] All animals need oxygen to go through the process of burning glucose for fuel. [3]

There are 7 organs/parts of the body we use to complete cellular respiration. Our mouth, nose, trachea, lungs, bronchi, alveoli, and diaphragm. We breath in through our mouth and nose, the oxygen travels down through our larynx, leading to our trachea (a tube that connects to the chest cavity). The trachea then divides into two smaller tubes, called the bronchi. The bronchus leads to the lungs, which divide into small air tracts called bronchioles, that carry small sacs called alveoli. Alveoli are covered in capillaries, blood vessels. And a pulmonary vein that carry oxygen-rich blood around the body. When the oxygen reaches the alveoli, the oxygen diffuses through the capillaries, while carbon dioxide diffuses into the alveoli. During our exhale we release carbon dioxide.
The thoracic diaphragm or diaphragm is located below the ribcage. It aids in respiration, helping us exhale and inhale. When we inhale the diaphragm contracts, allowing for air to come in. When we exhale the diaphragm relaxes into a dome shape.

Bivalves are mainly inactive animals. They use their gills to breath. [4] The incurrent and excurrent are the entrance and exit to a bivalves body. That is the way they inhale and exhale.Their heart has 3 chambers: two auricles. which receive blood from the gills, and a single ventricle. The organs are bathed in hemolymph, a fluid in the circulatory system. The ventricle is a muscle that pumps hemolymph through to the aorta an then to the rest of the body. Oxygen is absorbed in the hemolymph in the gills. The gills are in the mantle cavity.
