Lethbridge Herald, The (Newspaper) - August 22, 1973, Lethbridge, Alberta THE LETHBWDGE HERAID 197J Ask Andy Clams have hearts Andy sends a complete 20- volume set the Merit Stu- dents Encyclopedia to Lisa age of Allen- for her question. Does the clam have a The clam likes to bury him- pelf in sandy or muddy jeaches. He wears two saucer- tbaped shells and when fully Iressed one of the small type ilams can nestle in the hollow of. your hand. he has a heart. But as you would ex- it must be a very small one. It also is less compli- cated than the big human heart. But the clam's simple little heart works just fine for his simple little body. The heart of a clam or any other creature is somewhat like a fist made of sturdy mus- cle. It works like a pump to circulate nourishing blood among the 'body's busy living cells. A single-celled such as the does not need a heart. Many slightly larger creatures have more cells arranged In two simpli- fied layers. They do not need hearts either because their nourishing fluids can seep from cell to celL none of these mid- gets have backbones or bones of any sort Neither do a lot of much larger such as earthworms and in- Bects. their bodies ere made from multitudes ot cells organized to do special such as digesting food. These creatures need pumping hearts to circulate oxygen and nutrients throughout their bodies. The simplest heart Is a bulge In a blood vessel that fills and empties as it pumps. An earth- worm has several pairs of these hearts. More advanced animals have or four com or chambers inside their hearts. Most fishes have two frogs and turt- les have three. mamals and humans have four-chamb- ered hearts. You might expect the clam to have the simplest kind of heart. After he is not ad- vanced enough to have a bony sikelton like the fishes. ac- his tiny heart has three tinier chambers. his colorless blood successfully carries dissolved gases and floating particles of nourish- ment among his busy cells. As in more advanced ani- the clam's heart works on a team together with his his intestines and his gills. His internal organs are held together in a soft pack- which is wrapped in a loose fleshy flap called the mantle. His gills are elaborate pockets on the inside of his mantle. They are stuffed with tiny blood ves- sesl and washed with streams of water that flow in and out through the partly opened shells. The same streaming water also serves scraps of food to the clam's little mouth. His pumping heart cirulates the blood through a network of pores and pockets. Along the the blood gath- ers digested food and fresh oxy- gen from the gills and delivers them to the cells. The tiny heart is folded around the clam's Intestine and wrapped in a soft sack of fluid. It pumps the blood through ar- teries in two for- ward and backward. The for- ward stream is pushed through the internal organs and also through the clam's muscular foot. The backward stream is pushed through the fleshy man' tie. There some of it Beeps through pores and fine ves sels that lead to and from the gills. Chronicle Publishing Co. Fun with figures By J. A.

When Sooth ihowed his second suit West elected to rather latooos action. It was most that the final con- Iract woold be fat aunonos and since West cooW not double either hearts or he would have been tetter advised to let nature coarse.

With nothing to go declarer might have tried to cash the- ace hot East would have been able to raff and play a trump. With only two trumps remaining in dum- declarer would have had to surrender another di- amond trick and two fidf down one. Unfortunately for the de- West's double of three diamonds forewarned declarer of the bad break. So at trick South led a not the ace. He played a low and the defenders were pow- erless. West won the diamond lead with the nine and did the best he. could by return- ing m trump. South won ia ruffed a diamond in returned to his hand with a spade ruff and trumped his remaining low diamond with dummy's last heart. A spade ruff was the entry to declarer's hand to Iraw trumps and cash the ace 4f diamonds for the fame-going tricks. Note that even without Vest's tipoff it would have been proper technique for declarer to pUy the hand as he did. As he can afford to lose one diamond but not a sec- end lead of a low diamond is a safety play to protect a break.

Hysterectoiiiy vs. tied tubes Dear Dr. Lamb There are sseveral girls in our office who are curious about certain issues of birth cor4rol. We often hear of women having complete hys- terectomies instead of tubal ligations. This seems rather senseless to us. Why would they choose a hysterectomy over a tubal When a woman has her tubes tied are there any side What actually Does the ovary stop producing or does the tie prevent the eggs from reaching the womb. H the eggs are still does this cause some damage from the eggs backing up in the wo- men's system. How easy is it to obtain a tubal Is it a matter between patient and or are some hospitals opposed to Dear Reader Some wo- men have a hysterectomy be- cause they have problems with their such as a tumor or excessive bleeding. of also results in their being sterile. The body of the uterus and the cervix are fre- quent sites of cancer in the fe- male. The complete removal of the uterus and cervix elimin- ates the likelihood of this pro- blem in the future. Tying the tubes does not. When the tubes are tied this literally removes the ability of the ova to pass down the tube into the uterus for implantation and pregnancy. This has no ef- fect whatsoever on the ovar- ies. The ovaries are anatomi- cally separated from the mouth or opening of the tubes. The egg is released by the passes a very short literally in the open and enters the mouth of the tube. This means after the tubes are ovulation continues as it did before. The cannot pass down the so they are literally absorbed by the body. They are not blocked up in the since they are released as they always have in to the free space. This actually is somewhat different than the vasectomy in the male where there is a con- necting tube between the body of the testicle to the prostate and point of exit of sperm cells. Tying off the vas does block the emission of sperm but tying off the tube hi a wo- does not block the emis- sion of ova. ___ Not all doctors are'wiling to do tubal legations. It is against some doctor's religious and the same can be said about some hospitals. The only real way to find out is to discuss it with your own if one has reason to seriously consid- er such en operation. Dear Dr. Lamb Medically what is moderate How many drinks a Dear Reader A Tsmall amount of liquor for a person with underlying brain damage can cause uncontrollable rages or abnormal behavior. In a sev- ere case of ulcers it may cause bleeding. Even in a healthy per- the accumulated affects can cause liver brain damage and other medical pro- blems. No one should form a habit of having even one drink a and it's inadvisable to drink more than four drinks for any occasion. These should be drunk no more rapidly than one drink per hour and you should wait at least an hour after the last drink before driving. Drinks should be limited to one jig- ger of whiskey or a similar beverage in making a cock- or one bottle of or a half a glass of wine. Send your questions to Dr. in care of this news- P.O.
