Vascular resistance equation
R = 8nl/piR^4
Vascular resistance increases when:
vessel length and blood viscosity increases
what is the normal range for PR interval at resting heart rate
0.15 seconds
what is the effect of a spinal-medullary transection on respiration?
cessation of breathing
what is the effect of a pons-medullary transection on respiration?
basic pattern of respiration is maintained as it leaves the pre-botzinger pattern generator intact, however regulation of breathing would be impacted
What is physiological dead space?
volume of anatomical dead space plus non-functional areas of respiratory zone

Basolateral membrane of thick ascending limb, efflux pathway for CL-
Where is NKCC2 found and what is its function?
Apical membrane of thick ascending limb, mediates uptake of Na+ and Cl-
Where is ROMK found and what is its function?
Apical membrane of thick ascending limb, mediates K+ loss
Where does fertilisation take place?
Ampulla of fallopian tube
Which layer of epidermis only exists in layers of body covered by thick skin
Stratum lucidum

What is a tropic hormone?
Hormones with other endocrine glands as their target - most are secreted by anterior pituitary
Which germ layer(s) can epithelial tissue develop from
Endoderm, mesoderm and ectoderm
