It is microscopic and is an organism, such as a virus or bacteria. 4 of 16 Mitochondria Structures in the cytoplasm of all cells where respiration takes place (singular is mitochondrion). 5 of 16 Oxidise To add oxygen or to combine with oxygen. 6 of 16 Power of Hydrogen (pH) Scale of acidity or alkalinity. A pH (power of hydrogen) level below 7 is acidic, a pH level above 7 is alkaline. 7 of 16 Alveoli Tiny air sacs in the lungs, where gas is exchanged during breathing. 8 of 16 Bronchi The plural of 'bronchus'. The bronchi are the two major air tubes in the lungs. 9 of 16 Bronchioles The many small, branching tubes into which the bronchi subdivide. 10 of 16 Cilia Tiny hair-like projections from a cell that usually allow it to move a substance past the cell (for example, in the bronchioles in the lungs). 11 of 16 Diaphragm A large sheet of muscle that separates the lungs from the abdominal cavity. 12 of 16 Intercostal Muscles Muscles between the ribs which raise the ribcage by contracting and lower it by relaxing. 13 of 16 Pathogens Micro-organisms that cause disease. 14 of 16 Respire To engage in respiration, the energy-producing process inside living cells. 15 of 16 Trachea The major airway in the respiratory system, also known as the windpipe, connecting the pharynx and larynx to the lungs. 16 of 16
