renal fascia
renal cortex
renal medulla
renal pelvis
question 13

Explanation:

• For the first question: The renin - angiotensin mechanism acts to increase blood pressure. Renin is released when blood pressure drops. Renin converts angiotensinogen to angiotensin I, which is then converted to angiotensin II. Angiotensin II causes vasoconstriction (narrowing of blood vessels) and also stimulates the release of aldosterone (which increases sodium and water reabsorption in the kidneys, increasing blood volume). Both vasoconstriction and increased blood volume raise blood pressure.
• For the second question: The kidney has three main tissue layers. The renal fascia is the outermost connective - tissue layer. The renal cortex is the outer parenchymal (functional tissue) layer. The renal medulla is the inner parenchymal layer, consisting of renal pyramids. The renal pelvis is the funnel - shaped structure that collects urine from the renal pyramids and transports it to the ureter.

Answer:

• First question: True
• Second question: renal medulla
