Respiration And Breathing Flashcards
Respiration
The process that releases energy from food is respiration
The Equation for respiration
Glucose+Oxygen carbon dioxide +water+energy
Aerobic respiration
Needs oxygen to release energy from food
Anaerobic respiration
Does not use oxygen to release energy from food
How does oxygen get to cells
Oxygen is carried by the haemoglobin in red blood cells to all the other cells in the body
Example of anaerobic respiration
Yeast converts sugars to alcohol in fermentation this produces alcohol for drinks such as beer and wine
Nose
We inhale through our nose
Hairs and mucus trap dirt
Air is warmed by blood vessels
Trachea
Windpipe that carries air to and from the lungs it is made of c-shaped rings of rigid cartilage (to prevent it from collapsing.
Bronchus and bronchioles
We have 2 bronchi. Each bronchus carries air between the trachea and lung. The 2 bronchi subdivide many times to form tiny cubes called bronchioles. Bronchioles carry air to and from air sacs, or alveoli.
Alveolus
Each lung contains millions of tiny air sacs called alveoli. The function of each alveolus is gas exchange. Oxygen passes from the air in the alveolus into the blood vessels at the same time carbon dioxide and blood vessels into each alveolus
Diaphragm
The diaphragm is a sheet of muscle that forms the base of the chest. Along with the ribs and intercostal muscles. The diaphragm causes air to move into or out of the lungs.
