Respiration And Breathing Flashcards
Respiration
~ The process that releases energy from food is respiration
Equation For Respiration
~ Glucose+Oxygen ➡️ 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 red blood cells to all other cells of the body.
Examples Of Anaerobic Respiration
~ Yeast converts sugar to alcohol in “Fermentation” - this produces alcohol for drinks such as beers and wine!
Nose
~ We are supposed to inhale through our nose because the hairs and mucus trap dirt particles and bacteria in the nose.
~ Air is warmed and moistened by the blood vessels. Warm, 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. It is made of C-shaped rings of rigid cartilage to prevent it from collapsing.
Bronchus and Bronchioles
~We have two bronchi. Each bronchus carries air between the trachea and a lung. The two bronchi subdivide many times to form tiny tubes called bronchioles. Bronchioles carry air to and from the alveoli.
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. Along with ribs and intercostal muscles the diaphragm causes air to move into or out of the lungs.
