Now consider a drug which is being constantly infused into a patient to establish a plasma concentration of 2mg/L. GFR in this patient is 150ml/min. The substance appears in the urine at a rate of 200µg/min. The substance is being filtered, and is not metabolised. What do we know about the handling of this substance in the nephron? Select 2 answers. O The substance must be reabsorbed. O The substance must not be reabsorbed. O We can't know from these data if the substance is being reabsorbed. The substance must be secreted. The substance must not be secreted. O We can't know from these data if the substance is being secreted.

Tissue regeneration & repair

Tissue regeneration involves the restoration of tissue components by regrowth of damaged tissues. In contrast, tissue repair involves patching of injured tissue rather than restoring it. It is the proliferative capacity of the cells that decides the amount of regeneration against the repair that would occur in the tissue. Both regeneration and repair depending on the duration of the injury and response to the inflammation.
