Question

The capillaries that surround the renal tubules originate at the....

		Interior Vena Cava
		Vasa Recta
		Efferent arteriole
		Renal vein
		None of these

1. Blood supply TO the kidneys comes from the....

   		Renal vein
   		Abdominal aorta
   		Azygos vein
   		Thoracic Aorta
   		Inferior Vena Cava

Why would sodium reabsorption help maintain body fluid volume?

		Sodium weighs a lot so it helps make us feel full.
		Where salt goes, water follows.
		Sodium is never reabsorbed in the nephron.
		Sodium is a negative ion.

The loop of the nephron is primarily located in which 'layer' of the kidney?

Answer 1

1)OPTION C- EFFERENT ARTERIOLES

the capillaries surrounding the renal tubules are called peritubular capillaries , they are orginating from the Efferent arterioles of the kidney. it is mainly seen in the cortical part of the nephron

Vasa recta are the straight arterioles that run paralell to the Henles loop.

2)Option B -ABDOMINAL AORTA

The kidneys are supplied by the right and left renal artery .

Renal artery orginate from the inferior side of Abdominal aorta

3)Option B - Where salt goes, water follows

sodium ions has a great role in maintaining the body volume.because , when the concentration of the sodium is high in blood vessel , there will be increased absorption of the water .it increases the Body blood volume

4)The loop of the nephron are primarly seen in the RENAL MEDULLA

Renal medulla is the innermost part of the kidney

Renal cortex is the outer part of the kidney where the Glomerulus,Proximal convoluted tubules,distal convoluted tubules are seen.
