Glomerular ultrafiltrate would normally not contain:
1. plasma proteins
2. glucose and amino acids
3. water
4. urea
Bony fishes are:
1. ureotelic | 2. ammonotelic |
3. uricotelic | 4. Either 1 or 3 |
Urea in humans is synthesized in:
1. Kidneys | 2. Renal vein |
3. Liver | 4. Urinary bladder |
The region of human kidney where you expect to find maximum osmolarity is:
1. at the top of the renal cortex
2. at the bottom of the renal cortex
3. at the top of the renal medulla
4. at the bottom of the renal medulla
Sodium is the principal cation in blood. If the blood concentration of sodium ions gets below normal:
1. blood volume increases and blood pressure decreases
2. water drains from the collecting duct
3. blood volume and blood pressure decrease
4. ADH secretion increases
RAAS is opposed by:
1. | ADH | 2. | renin |
3. | atrial natriuretic peptide | 4. | angiotensin II |
Mammals are:
1. osmoconformers.
2. hypotonic to their environment.
3. hypertonic to their environment.
4. osmoregulators.
The most toxic nitrogenous metabolic waste product is:
1. ammonia | 2. urea |
3. uric acid | 4. methane |
Kidneys are not involved in:
1. Osmoregulation
2. Activation of Vitamin D
3. Secreting hormones
4. Glycogenesis
Malpighian body or the renal corpuscle is made up of:
1. Glomerular capillaries and PTCN
2. Bowman's capsule and renal tubules
3. Afferent and efferent arterioles
4. Glomerular capillaries and Bowman's capsule
