13.The kidney receives nearly 20% of the cardiac output.It is a cycke betwern heart and kidneys. The blood circulation of it is as following

From heart ,the pure blood or oxygenated blood is carried by the aorta 》》then it travels towards abdomen forming abdominal aorta 》》it further divides into two Renal artery (left and right)》》Each artery fivides into 5 segmental artery 》》then this divides and gives out interlobar artery》》followed by interlobular artery》》 forming the arcuate artety》》then forms the afferent arterioles》》enters the "glomerulas" (glomerular filterarion occur)》》then the blood enters the interlobular vein 》》again to interlobar veins 》》 finally reaching the efferent arteriole》》Renal vein 》》the end being carrying blood to heart through vena cava

Ans.c.Afferent arterioles to glomerular capillaries to the efferent arteriole

Ans.14.c.Afferent arterioles to glomerular capillaries to the efferent arterioles

15.Herpes simplex infection is a skin infection spreads by direct contact. The recurrence is 60 to 95%.When infection occurs it tends to travel by sensory nerves and reside life long in the nerve cells.When the individual are highly stressful, weak immune in later stage of life may get reoccurance of infection.

Ans.B The virus persists in latent phase in sensory nerve ganglia

16.Goitre refers to enlarged thyroid gland.It is common among women.In United States the use of iodised salt is more due to lack of iodine in food in Latin America and central America.But people living in mountainous area are highly prone for goitre
