Lung capacities are of four types:

1) Inspiratory capacity
2) Functional residual capacity
3) Vital capacity
4)Total lung capacity

#Unit 4. Cell Communication and Cell Signaling

Outside-in signaling

Binding of integrins to their ligands induces conformational changes in their cytoplasmic domains, directly or indirectly altering their interactions with cytoplasmic proteins

#Unit 4. Cell Communication and Cell Signaling

Inside-out signaling

intracellular signaling pathways can, via adapter proteins, modify the ability of integrins to bind

to their extracellular ligands
