the blood as the blood plasma is filtered from water, wastes, minerals &
glucose to be collected in the nephric tubule.

Reabsorption process “active / passive” of:
plasma contents to return water, minerals and glucose that the body needs

Urine passes down the collecting duct to:

the pelvis to be collected and passes

to the ureter then to the bladder to be stored.

the urethra to be expelled out.

Reabsorption: a biological process in which the body reabsorbs the

required water, glucose and minerals to be back again into the blood,

leaving the wastes.

If the kidney expels all the 1.2 : 1.3 L of blood passes 3 L of plasma from the
filtered fluid, the body will through kidneys / min. total blood volume
