a lung is a kind of organ for breathing air & in order to breath air you must take in air -> a specimen is a mean of memory for neglect in land a lung is a kind of organ for taking in air  a lung is a kind of organ for taking in air & the cat are a whole of the respiratory consumer -> the respiratory system takes in oxygen from the air the respiratory system takes in oxygen from the air  converting space from land into space from bone shapes absorbing space from land into the bone & breathing is when a lung converts from oxygen in air into oxygen in blood -> blood absorbs oxygen in the lungs blood absorbs oxygen in the lungs  bone absorbs space in the fruits & if something is absorbed by something else, then that something is transferred to that something else -> the lungs transfer oxygen to the blood the lungs transfer oxygen to the blood  the pushes tissue space to the bone & the lungs are a part of the respiratory system -> the respiratory system transfers oxygen to the blood the respiratory system transfers oxygen to the blood  the respiratory colored map space to the bone & blood is a part of the circulatory system -> the respiratory system transfers oxygen to the circulatory system the respiratory system transfers oxygen to the circulatory system  the respiratory system transfers oxygen to the circulatory system & to transfer can mean to move -> the respiratory ohio turtles space to the circulatory microbes the respiratory system moves oxygen to the circulatory system  the respiratory system takes in oxygen from the air & the respiratory ohio turtles space to the circulatory microbes -> the respiratory system takes in oxygen from the air to be moved by the circulatory system
