PATHO 101

4. Restoration of the electrical gradient following depolarisation
12. Electrical change across a cell membrane that initiates cardiac contraction
13. The alveoli are getting air, but the blood isn't showing up to the party
14. Controlled and programmed cell death
15. A measure of how easily the lungs or another elastic structure can expand
18. The stretch placed on ventricular muscle before contraction
19. When hydrogen ions accumulate and the body's pH heads south
20. A chemical messenger such as adrenaline or noradrenaline released during sympathetic activation

1. The resistance the ventricle must overcome to eject blood
2. Contraction of airway smooth muscle causing narrowing and increased resistance
3. Passive movement of molecules from an area of higher concentration to lower concentration
5. An organ's ability to maintain relatively stable blood flow despite changes in perfusion pressure
6. Blood reaches the lungs but bypasses effective gas exchange
7. Insufficient oxygen available at the tissue level
8. The body's ongoing process of maintaining a stable internal environment
9. Inadequate blood supply leaves tissue short of oxygen and nutrients
10. More ventricular filling produces greater stretch and a stronger contraction within physiological limits
11. Widening of blood vessels resulting in reduced vascular resistance
16. Movement of water across a semipermeable membrane toward the higher solute concentration
17. The cellular pathway that breaks glucose down into pyruvate while producing ATP
