Breathing And The Respiratory System Flashcards
Respiration
The process that releases energy from this food is respiration
Equation for respiration
The equation for respiration is:
glucose + oxegyn » carbon dioxide +water +energy
Aerobic respiration
Aerobic respiration Needs oxygen to release energy from food.
Anaerobic respiration
Anaerobic respiration does not use oxygen to release energy from food
How does oxygen get to our cells?
Oxygen is carried by the haemoglobin in the red blood cells to all of the other cells in the body.
Examples of anaerobic respiration
Yeast converts sugars to alcohol in fermentation - this produces alcohol for drinks such as beer and wine.
Nose
Hairs and mucus trap dirt particles and bacteria in the nose, air is warmed and moistened as it passes through the nose. Warm and moist air helps oxygen to pass from the lungs into the bloodstream more easily.
Trachea
The trachea, or windpipe, carries air to and from the lungs.
Bronchus and bronchioles
We have two bronchi. Each bronchus carries air between the trachea and a lung.
Alveolus
Each lung contains millions of tiny air sacs called alveoli. The function of each alveolus is gas exchange
Diaphragm
The diaphragm is a sheet of muscle that forms the base of the chest. The diaphragm causes air to move into or out of the lungs.
