Homework Answers
1.- norepinephrine: released by sympathetic neuron to increase heart rate.
2. Gap junctions:- synapses of sympathetic and parasympathetic muscle.
3. SL valve in right valve:- tricuspid valve.
4. Second heart sound :- Aortic valve
5. AV node:- rapidly construct action potential across cardiac muscle fibre.
6. Slow calcium channel:- responsible for cardiac action potential platuea.
7. AV bundle:- conduct impulse from AV node to purkinji fibre.
8. AV valve of right heart:- tricuspid valve
9. Sinus nodal fibers:- conduct impulse from AV nodes to the purkinji fibre.
10.systole:- period of contraction of cardiac muscle.
11. Acetyl choline:- released by parasympathetic neuron and decrease heart rate.
12. Varicositices:- self excite due to continum sodium leakage.
13. P waves on EkG:- represent atrial depolarisation.
14. Beta receptor:- expressed in heart and bind epinephrine and norepinephrine.
15. Muscarinic receptors:- expressed in heart and bind acetyl choline.

NAME SID__ 31. Which of the following is a correct statement when comparing Open Circulatory Systems and Closed Circulatory Systems? a. Open Circulatory Systems generally require MORE energy to operate, since it is less efficient to circulate the entire amount of interstitial fluid in the body cavity. 8. Arthropods and Insects generally use a Closed Circulatory System, while vertebrates generally use an Open Circulatory System Both systems utilize some form of the following three components: (1) circulatory fluid, (2) vessels...
