Flashcards in The Repiratory System Deck (14):
Where dose air pass through first and what happens?
Air is warmed, moistened, and filters as it travels though the mouth and nasal passages.
It then passes through the trachea and the 'bronchis'.
What are the bronchi?
They are the two major tubes in the lungs.
What happens when you breath?
Air is warmed, moistened and filterdas it travels through the mouth and nasal passages. It then passes through the trachea and one of the two bronchi. Into the lungs. After passing into the many bronchioles, it finial,y Arvin's into some of the millions of tiny sacs called alveoli. This is where gas exchange take place- oxygen passes through out the air into the blood, and carbon dioxide passes out of the blood into the air in the alveoli.
What happens to your body when you breathe?
The intercostal muscles contract, expanding the rib age.
The diaphragm contracts, pulling downwards to increase the volume of the chest.
Pressure inside the chest id lowers and air is sucked into the lungs.
What Halle d when you exhale? When breathing.
The intercostal muscles: between the ribs which raise the rib cage by contracting and lower it by relaxing relax , the rib cage drops inwards and downwards.
The diaphragm: a large sheet of muscles that's separates the lungs from the abdominal cavity relaxes, moving back upwards, decreasing in the volume of the chest.
What is respiration?
The release of energy from the glucose in the muscles.
What is aerobic?
When the body is at a rest. With oxygen respiration. As you exercise you breathe harder and deeper and the heart beats faster to get oxygen to the muscles.
What is the equation for Aerobic exercise?
Glucose + oxygen = energy + water + carbon dioxide
What is anaerobic?
When exercising very hard, the heart cannot get enough oxygen to the muscles. Respiration then becomes anaerobic.
What is the equation for anaerobic?
Glucose = energy + lactic acid
When you inhale air contains?
More oxygen is used to create energy less carbon than exhaling
When you exhale what dose the air contain?
More carbon dioxide procured as a waste product of energy production. Less oxygen as it has been used in respiration.
What is gas exchange?
When oxygen passes through the capillary wall into the tissues; carbon dioxide passes from the tissues into the blood.
