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

Filtration slits in the glomerular membrane are formed by:
1. The capillary endothelial cells
2. The basement membrane
3. The podocyte cells
4. Mesangial cells

All the following are secreted by the tubules of nephrons except:

A hormone formed in the blood that causes vasoconstriction is:

In the male, urethra serves to:
1. transport urine from kidney to bladder
2. transport sperms to ejaculatory ducts
3. store urine and sperms
4. discharge semen and urine

The functional unit of the human kidney is the:

The vascular endothelium of glomerular capillaries, basement membrane, and podocytes in the inner lining of Bowman’s capsule form:

A series of straight capillaries in the medulla that lie parallel to the loop of Henle are called:

About what percent of the glomerular ultrafiltrate is reabsorbed by the tubules during urine formation?

The part of the nephron where both hydrogen and potassium ions are secreted into the tubular fluid is the
