1. The afferent arterioles subdivides into a network of capillaries the peritubular capillaries.


2. Mammalian kidney is adapted to conserve water by over 99.5 % reabsorption of glomerular filtrate.


3. Main factor for the production of hypertonic urine in mammals is the gradual increase in osmotic concentration from cortex to inner medulla of kidney.


4. Hemodialysis is the only type of dialysis for removal of nitrogenous wastes.


5. High temperature denatures the enzymes and damages the metabolism


6. Some plants are adapted to high temperature by synthesizing heat shock proteins, which embrace enzyme and other protein.


7. Animals that generate their own body heat through heat production as by product during metabolism are called ectotherm
