The human pancrease is situated near the curve of the duodenum, in the abdonimal cavity.It has a broad head, a body and a narrow tail.
It functions both as endocrine and exocrine glands.The exocrine part is made up of lobules ,each lobules consits of small alveoli like secreting cells.(acini cells) that secrete pancreatic juice.
Amylose, lipase, nucleases, tripsinogen and chymotripsinogen are the enzymes found in the pancreatic juice along with water and mineral salts.
Lobules drained by small ducts join together to form the pancreatic duct.
Istlets of Langerhans are the endocrine part, that consists of alpha and beta cells .Aplha cells secrete glucagon and beta cells secrete insulin.

THE IMPORTANCE OF WATER IN ITS CHEMICAL AND PHYSICAL PROPERTIES FOR LIFE
Water is very esssential for life.
Water has a high polarity meaning that it is a powerful solvent and thus being the medium of the protoplasm.Biochemical reaction in the protoplasm take place in the aqueous medium.

How To Get your Google Adsense Account Turned Back On.So, let me guess... you received a little email from the Google Adsense Team about fradulent clicks... and bla bla bal.. to make a long story short they banned your account. Right? oh and to make matters worse i'm sure they said... uh also we are going to k eep all of the money you have made because we are going to... uh... give it back to uh... uh... give it back to the..... people who paid for those clicks.. yeah.. that's what we are going to do!Of course the letter was a bit more professional than that.. in fact it was so professional that every thing I have ever read on this subject pointed to one thing... EVERY ONE gets that letter! well not Every one. but its the same letter! then you can appeal your account. and you get another letter... and by the way.. everyone gets the same thing once you appeal. I'm sure it's just some person some place copying and pasting pre written text into an email after they.. psudo read what you had to say. Well, here's the deal. You are here to figure out HOW to get your Adsense Account back on.. reinstated... reactivated.. whatever you want to call it.. you just want to start getting money again. Right? of course. Well here is how it's done! Article Continued Below |
We all know how to make money with Google Adsense, but the question is.. what happens when you get hit with the good ol' fraudlent clicks deal and your ads get turned off? First you Appeal.Step 1. Appeal |

Heart Lecture Test Questions – Set 2
Heart Lecture Test Questions – Set 2
1. The ability to spontaneously depolarize, without nervous control:a. stenosisb. stroke volumec. diastoled. myogenicitye. systole
2. The ability to spontaneously depolarize, without nervous control, at regular intervals:a. autorhythmicityb. stroke volumec. diastoled. systolee. myogenicity
3. The normal "pacemaker" of the heart is the:a. brainb. ventriclesc. Purkinje fibersd. atrio-ventricular nodee. sino-atrial node
4. Which of the following conduction sequences is in correct order:a. AV node->internodal pathways->bundle of His->Purkinje fibers->SA node-bundle branchesb. SA node->AV node->Purkinje fibers->bundle of His->bundle branches->internodalpathwaysc. bundle of His->bundle branches->Purkinje fibers->AV node->inter-nodal pathways->SAnoded. SA node->internodal pathways->AV node->bundle or His->bundle branches->Purkinjefiberse. Purkinje fibers->bundle of His->bundle branches->internodal pathways->SA node->AVnode
5. In discussing the conducting fibers of the sino-atrial node, atrio-ventricular node, bundle of His,bundle branches and Purkinje fibers, the following may be stated (regarding one, or all ofthem):a. composed of modified cardiac muscleb. spontaneous rhythmicity and conductivity more highly developed than the rest of the heartc. initiates and transmits a depolarization wave with a rapid rate which passes through allparts of the myocardiumd. can be regulated by the autonomic (visceral) nervous systeme. all of the above
6. If the conducted depolarizations from the sino-atrial node are blocked, the ventriculardepolarizations are initiated in the:a. atrio-ventricular node, which will exhibit rhythmic depolarizations, but at a lower rateb. heart stops functioning because no depolarizations reach the ventriclesc. cardiac muscle of the atrial walls itself begin spontaneous contraction and conductiond. interatrial septume. none of the above
7. What is the effect of a heart block:a. prevents the atria from contractingb. blocks the atrio-ventricular conducting system, thus abolishing the synchronization of atriaand ventriclesc. plugs up the coronary arteries, depriving the heart muscle of oxygen and nutrients, causinglocal cell deathd. would only operate in stress conditionse. causes the ventricles to become the overall heart "pacemaker"
8. A heart block is due to:a. failure of the atrio-ventricular node to receive and/or to transmit depolarizationsb. failure of the sino-atrial node to receive stimulic. failure of the atrio-ventricular node to stimulate atrial muscled. lack of blood supply to the livere. permanent closure of a heart valve
9. The atrio-ventricular node's primary function is:a. conduction of a depolarization wave through the atriab. conduction of a depolarization wave through the ventriclesc. delay conduction from the atria to the ventricles, to allow atrial conduction to be completedd. to act as the heart's overall pacemakere. unknown
10. Which of the following has the fastest conduction speed:a. sino-atrial nodeb. internodal pathwaysc. atrio-ventricular noded. Purkinje fiberse. unmodified cardiac muscle fibers
11. The fastest conduction speed is within the:a. sino-atrial nodeb. internodal pathwaysc. atrio-ventricular noded. ventricular conducting systeme. moderator band
12. Why is the ventricular conduction system's speed so fast:a. there is much more myocardium to stimulate to contractb. depolarization is less effectivec. gravity has more effect, since this is beneath the atriad. simply because the atrial conduction is firste. it is not faster [trick question]
13. Why does ventricular depolarization and resulting contraction begin in the apex and thenprogress towards the base:a. the heart is positioned more to the left of the body's midlineb. the ventricular conducting system is more extensive than the atrial systemc. this prolongs its action, to prevent overlap with atrial systoled. this produces a milking action which squeezes the maximum amount of blood into the aortaand pulmonary trunke. there is no particular logic
14. Sequential contraction throughout the heart, from cell-to-cell conduction of depolarization, isfrom which feature:a. all-or-none responseb. myogenicityc. syncytial fibersd. independent tonee. autorhythmicity
15. Which of the following would be the most reasonable time for complete spread of thedepolarization wave from the sino-atrial node to the final ventricular contractile fibers:a. 0.09 secondb. 0.22 secondc. 1.50 secondsd. 4.50 secondse. 0.50 second
16. What is the function of the atrio-ventricular node:a. produces a strategic delay from atria to ventricles, permitting ventricular filling to becompletedb. allows one-way conduction from atria to ventriclesc. permits communication between atria and ventricular conducting systemd. can act as a secondary pacemaker if a blockage occurs with the internodal pathwayse. all of the above
17. A strategic delay in conduction from the atria to the ventricles is accomplished by:a. internodal pathwaysb. junctional fibers of the A-V nodec. bundle of Hisd. trabeculae carneaee. S-A node
18. The heart can not be tetanized because:a. it is myogenicb. it is autorhythmicc. of the long refractory period of cardiac muscle cellsd. its tone is independent of the nervous systeme. all of the above
19. The cardiac cycle is:a. the conduction phenomenab. shown by the EKGc. that the more the heart is stretched the more forceful will be its contractionsd. the alternate contraction and relaxation of the atria and the ventriclese. none of the above
20. Of the following, the longest should be:a. atrial systoleb. ventricular systolec. atrial diastoled. ventricular diastolee. none of the above, since they are all of the same duration
21. Which of the following do not occur simultaneously:a. atrial systole and ventricular systoleb. atrial diastole and ventricular diastolec. atrial diastole and ventricular systoled. atrial systole and ventricular diastolee. left ventricular systole and right ventricular systole
22. Cardiac muscle cells form an interconnected mass, permitting cell-to-cell conduction; thissituation if termed:a. syncytiumb. all-or-nonec. toned. myogenicitye. autorhythmicity
23. Which of the following occur simultaneously:a. right atrial systole and left ventricular systoleb. right atrial diastole and right ventricular diastolec. right atrial systole and right ventricular systoled. left atrial systole and left ventricular systolee. left atrial systole and right ventricular systole
24. What event is responsible for most ventricular filling:a. vibration of the moderator bandb. sucking action from ventricular diastolec. pressure from atrial systoled. atrial diastolee. none of the above
25. Atrial systole is most important for:a. filling the ventricles with the greatest volume of bloodb. preventing backflow through the A-V valvesc. preventing backflow through the semilunar valvesd. producing the necessary amount of ventricular stretching during its fillinge. all of the above
