Consider the following four statements (i-iv) and select the option that correctly identifies the true (T) and false (F) ones. (i). Atrial natriuretic factor can cause vasodilation (dilation of blood vessels) and thereby decreases the blood pressure. (ii). On an average, 60-70 gm of urea is excreted out per day. (iii). Sebaceous glands eliminate certain substances like NaCl, urea and lactic acid through sebum. (iv). PCT is lined by simple cuboidal brush border epithelium which increases the surface area for reabsorption.
