Question 1 The young female should be instructed make sure she is existence carful when using the toilet and agreeable in sexual affinity hind end. This is because unseasonable toilet habits (wiping back to front after defecation) piece of tail comfortably carry fecal bacteria into the urethra. Also well-nigh urinary piece of fetch transmittals occur in sexually active women, because intercourse drives bacteria from the vagina and external genital arena toward the bladder. The use of spermicides magnifies this problem, because the spermicides kills face-saving bacteria, allowing septic fecal bacteria to colonize the vagina. Symptoms of urinary tract contagious diseases embarrass dysuria, urinary urgency and frequency, fever, and sometimes cloudy or broth-tinged weewee supply.

Text page 879 Question 2 Question 3 Factors which allow weewee to become more grueling are the intrinsic and unneeded controls which regular renal blood prey. By adjusting its own opposite to blood flow, a wait on called renal autoregulation, the kidney can apply a nearly unceasing GFR despite fluctuations in customary arterial blood military press. nephritic autoregulation entails two types of controls: a myogenic weapon and a tubuloglomerular feedback mechanism.

The myogenic mechanism reflects the intention of vascular smooth muscle builder to contract when stretched. Increasing the general blood pressure causes the receptive nerve arterioles to constrict, which restricts blood flow into the glomerulus and prevents glomerular blood pressure from climb to damaging levels. Declining systemic blood pressure causes dilation of receptive arterioles and raises glomerular hydrostatic pressure. Both responses help swan a normal GFR. Autoregulation by the flow-department tubuloglomerular feedback mechanism is directed by the macula densa cells of the juxtaglomerular apparatus.
