Bright Side "Some things in #life are bad They can really make you mad Other things just make you swear and curse. When you're chewing on #life's gristle Don't grumble, give a whistle And this'll help things turn out for the best... And...always look on the bright side of #life... Always look on the light side of #life... If #life seems jolly rotten There's something you've forgotten And that's to laugh and smile and dance and sing. When you're feeling in the dumps Don't be silly chumps Just purse your lips and whistle - that's the thing. And...always look on the bright side of #life... Always look on the light side of #life... For #life is quite absurd And death's the final word You must always face the curtain with a bow. Forget about your sin - give the audience a grin Enjoy it - it's your last chance anyhow. So always look on the bright side of death Just before you draw your terminal breath #life's a piece of shit When you look at it #life's a laugh and death's a joke, it's true. You'll see it's all a show Keep 'em laughing as you go Just remember that the last laugh is on you. And always look on the bright side of #life... Always look on the right side of #life... (Come on guys, cheer up!) Always look on the bright side of #life... Always look on the bright side of #life... (Worse things happen at sea, you know.) Always look on the bright side of #life... (I mean - what have you got to lose?) (You know, you come from nothing - you're going back to nothing. What have you lost? Nothing!) Always look on the right side of #life..." From #life of Brian
Renin-angiotensin-aldosterone System When the blood volume falls, kidneys secret renin which causes the activation of angiotensin, and creates angiotensin I, angiotensin I is converted to angiotensin II by an enzyme called angiotensin converting enzyme which is found in the lungs. Angiotensin II causes the constriction of muscles in the walls of arterioles which increases the blood pressure. Angiotensin II also causes the release of aldosterone hormone from adrenal glands. Aldosterone causes the kidneys to retain sodium ions (Na+). The retention of Na+ by kidneys leads to increased in movement of water into the renal capillaries, which causes the blood volume to increase. Now isn't that just beautiful??
