Breathing is the function of our body to let air flow to the lungs. It is important because it serves the purpose of bringing the amount of oxygen the body needs to work properly, and flushing out the toxic substances our body produces.
The diaphragm also plays its important role in respiratory system because it creates more space in our chest cavity, allowing the lungs to expand when we inhale.
The larynx connects the naso- and oro- pharynx with the trachea, functioning in air conduction, vocalisation and in obstructing passage of ingesta into the trachea during deglutition. The trachea divides into left and right mainstream bronchi. Bronchi give away to smaller conducting airways, bronchioles.
The walls of the alveoli share a membrane with the capillaries, this relatively lets the oxygen and carbon dioxide diffuse between the respiratory system and bloodstream. They bring oxygen into our body through inhalation and send carbon dioxide out called exhalation and overall process is respiration
Pneumonia is a life threatening illness because if our lungs is filled with fluid then they won’t be able to function normally and won’t be able to transfer enough oxygen to your blood or get rid of the carbon dioxide in our bloodstream
Explanation:The tetrahedral shape is formed by the electrons repulsing one another, which forms the tetrahedron—the shape in which all the electrons are as far away from one another as possible.
Examples include methane (CH4) and ammonium(NH4+).
Methane has a central carbon atom ringed by four hydrogens, which form the "spokes" of the tetrahedral molecule.
Tetrahedral molecules are nonpolar if the four surrounding atoms are the same, in the cases of methane and ammonium, and have a bond angle of 109.5˚.
However, tetrahedral molecules can also be polar if they are like chloroform (CHCl3). The central atom has four electron domains, but they are differently sized.
