Renal Physiology parts:

Question 1

Low Blood Pressure in Renal Blood Vessels

Intrinsic Mechanisms (2):

Answer 1

Myogenic Mechanism of Autoregulation

Tubuloglomerular mechanism of autoregulation

Question 2

Low Blood Pressure in Renal Blood Vessels

Extrinsic Mechanism (2)

Answer 2

Hormonal (renin-angiotensin) mechanism

Neural controls

Question 3

Low Blood Pressure in Renal Blood Vessels
Myogenic Mechanism of Autoregulation

Occurs in:

Causes:

Answer 3

Occurs in: Renal Vascular Smooth Muscle

Causes: Vasodilation

Question 4

Low Blood Pressure in Renal Blood Vessels
Tubuloglomerular mechanism of autoregulation

Occurs in:

Causes:

Answer 4

Occurs in: Macula densa cells of the JG apparatus

Causes: Vasodilation through chemical

Question 5

Low Blood Pressure in Renal Blood Vessels
Hormonal (renin-angiotensin) mechanism

Occurs in:

Causes:

Answer 5

Occurs in: JG cells of the JG apparatus

Causes: Renin release leading to Na+ reabsorption, more water, increased blood volume ALSO vasoconstriction

Question 6

Low Blood Pressure in Renal Blood Vessels
Neural controls

Occurs in:

Causes:

Answer 6

Occurs in: baroreceptors in blood vessels

Causes: Sympathetic nervous system to work and increase blood volume
