ATP
energy used in cellular levels
how is ATP produced?
cellular respiration
aerobic respiration
uses oxygen and glucose to produce energy, CO2 and water. produces lots of energy, occurs from the mitochondria
anaerobic respiration
uses glucose to produce energy lactic acid CO2. produces small amounts of energy compared to aerobic respiration. occurs in cytoplasm
effects on highly intense exercise
less aerobic respiration, more anaerobic respiration \, heart/lung can’t supply enough oxygen, more lactic acid produced
where does gas exchange occur
lungs
largest branch in the lungs
trachea
second largest branch in the lungs
bronchi
third largest branch in the lungs
bronchiole
tissue where gas exchange occurs
alveoli
muscle under the lungs that contract and expand when humans breathe
diaphragm
role of trachea
tube with incomplete rings of cartilage that carries air to the lungs. mucus and cilia are present
role of bronchi and bronchioles
carries air to the lungs
role of alveoli
small air sacs that are adapted for gas exchange
role of Diaphragm
Sheet of muscle which is domed; it helps make breathing movements
role of Ribs
Bones that protect and ventilate the lungs
role of Intercostal muscles
Move ribs for ventilation
role of Pleural membranes
Thin moist membranes forming an airtight seal around the lungs
function of cilia
cilia beats and pushes mucus up the throat to the nose
cells that are lined with in the way down the lungs
ciliated epithelial cell
function of mucus
made by goblet cells, traps bacteria, dust, viruses and prevents them going to the lung
