Hypoxia Flashcards
What is hypoxia
deprivation of oxygen to cells
Which cells are the most effected by hypoxia
highly oxygen dependent cells like brain, heart and kidney cells
What are some ways hypoxia happens
low oxygen % in the air
ichemia
respiratory disease
anemia
What is an important indicator of cell injury and death
intracellular enzymes leaking into the extracellular fliud
Can laboratories pick up these enzymes
yes
What does hypoxia do to the cell
without oxygen, anaerobic metabolism ramps up, building up lactic acid which drop pH which cause denaturing effects, also with less or no ATP produced the energy dependent Na/K membrane pump can’t work properly so NA and K aren’t balance in/out of the cell causing water and ions to build up in the cell
