11.3 The kidney and osmoregulation skills

HideShow resource information
Annotate the Bowman's capsule
Cup-shaped structure with highly porous walls that collects glomerular filtrate
1 of 15
Annotate the glomerulus
A tight-knot like, high pressure capillary bed that is the site of ultrafiltration
2 of 15
Annotate the afferent arteriole
Brings blood from renal artery
3 of 15
Annotate the efferent arteriole
Narrow vessel that restrcits blood flow, which helps generate high blood pressure in glomerulus
4 of 15
Annotate the vasa recta
Unbranched capillaries similar in shape to the Loop. Descending limb takes blood deep into the medulla, ascending limb brings it up to the cortex.
5 of 15
Annotate the loop of Henlé (ascending and descending walls)
A tube consisting of an ascending and descending limb that carries the filtrate deep into the medulla, and the AL brings it back to the cortex
6 of 15
Annotate the collecting duct
A wider tube that carries the filtrate back to the renal pelvis
7 of 15
Annotate the peritubular capillaries
Low-pressure capillary bed that absorbs fluid from the convoluted tubules
8 of 15
Annotate the venule
Carry blood to renal vein
9 of 15
Annotate the distal convoluted tubule
Highly twisted section, but with fewer and shorter microvilli and less mitochondria
10 of 15
Annotate the proximal convoluted tubule
Highly twisted section. Has many wall cells with many mitochondria and microvilli projecting into its lumen.

What should be present in a drawing of the kidney?
Ureter, renal pelvis, medulla, cortex, renal artery, renal vein
12 of 15
What should be annotated in a drawing of an egg?
Cytoplasm containing fat droplets, haploid nucleus, layer of follicle cells, two centrioles, zona pellucida, first polar body, cortical granules, 110 micrometre diameter
13 of 15
Order of blood flow through nephron
Afferent arteriole, glomerulus, efferent arteriole, peritubular capillaries, vasa recta, venule
14 of 15
What should be annotated in a drawing of a sperm?
Acrosome, head (3 um wide, 4 um long), plasma membrane, haploid nucleus, centriole, mid piece (7 um), helical mitochondria, tail (40 um), protein fibres to strengthen tale, microtubules in a 9+2 arrangement
