Q:Arrange these structures in the order in which blood passes through them-assume the blood is about to leave the right atrium.Put in order:AortaAortic semilunar valveLeft atriumLeft ventricleLungsMitral valvePulmonary arteryPulmonary semilunar valveRight ventricle Superior/inferior vena cavaTissues of the bodyTricuspid valve: R atrium Tricuspid valve R ventricle Pulmonary semilunar valve Pulmonary artery Lungs Pulmonary veins L atrium Mitral valve (bicuspid valve) L ventricle Aortic semilunar valve Aorta Systemic circulation (tissues of the body) Superior/ Inferior vena cava *The pulmonary veins are the only veins of the body that carry freshly oxygenated blood*

Q:I noticed when I pulled my pcv valve off the valve cover the entire guts were missing. what would this make the car run like?: It would just make a bunch of oil pool up in the intake. If it was plugged it could damage seals.

Q:I Have a 2001 Honda Accord 3.0 V6. Would a clogged EGR valve cause it to run rough and have problems starting up when it is warm? It also runs hot. I have replaced the thermostat and the cooling fan relay? What could cause all of this? PLEASE HELP!: You could have a vaccum leak that signals the computer that the egr valve is bad. The parts at autozone are good quality parts and most times better than the dealer. Something is causing the Egr to go bad..My guess is to look at the vaccum like your brother stated...Pcv. Egr is the Exaust Gas Recurrulation

Q:recently changed head gasket. could valves tap from the push rods being mixed up? they all seemed to be the same size and i know the other side was exactly the same when put back together but this side is mixed up. could this make the valves go crazy? and i need to replace my water pump because its getting very hot and no coolant moving. and everything is smokin up, took off oil cap and it was steaming. would that have anything to do with making the valves tap?: When you replaced the head gasket, did you properly adjust the valves, as in preload? Doesn't sound like it...as for different length push rods, you'll have to check that repair manual you went by...you did read the repair manual, right? As for the rest, head gaskets must go on only one way. Did you make sure all the holes lined up correctly, and one or more cooling passages weren't blocked by the gasket? Torqued properly, in sequence? Were the intake manifold and exhaust gaskets installed and torqued properly? Sorry to be a nag, but as you can see there is more to it than just unbolting and rebolting parts...

Q:I have a 3406b motor. It has blow by. This happened when I hired a mechenic to do a top end. I belive that he did not ajust the valves correctly or something happen to the motor. I want to gap the valves to see if this helps out. How would I go on doing this.: NO, valves does not contribute to blow by in this way.Blow-by is the compression of the cylinder getting past the piston rings during compression. Adjusting the valves is a procedure of the induction and exhaust systems. All engines experience a little blow-by which is supposed to pass through the PCV valve ventilating the crankcase. GOOD-LUCK!! BRILLIANT!!!!

Q:I don't know exactly what it is called...the water valve from the wall to the toilet is leaking. All of the parts need to be replaced. They appear old and corroded. Can you please tell me what these parts are called? About how much they cost? And is this difficult to do? I found an excellent video on youtube on how to replace..but just want to ask anyway if it's difficult..it doesn't LOOK difficult.: Before you start taking things apart try this. Find out where the water is coming from. You may have to sit there for a while to watch for a drip. If it is coming from where the knob to shut it off is, there is a nut behind the knob. Try tightening it a little. Don't really lean on it. If the leak is from the line to the toilet do the same thing. Just tightening things may solve your problem at no cost. Best of luck.

Q:My valve cover gasket has less them 2k miles on it and i noticed in some areas there is a lil oil shine around it so i was thinkin maybe i have to retighten the valve cover a lil bit more?: Not unusuall, just snug them, tho - Don't smash the gasket.

Q:this question was on my test for APII, the question is stated as:the tricuspid valve is closed...a) during rapid filling of the ventricles (this is the answer the teacher shows to be correct)b) by contraction of the papillary musclesc) while the atria contractd) during ventricular contraction (this is the answer i chose i got it wrong)please let me know to correct answer!! thanks!!: The bicuspid valve is the left atrioventricular valve, and the tricuspid valve is the right atrioventricular valve. Blood enters the heart via the Superior Vena Cava (and Inferior Vena Cava) into the Right Atrium. In between the Right Ventricle and the Right Atrium is the Tricuspid Valve. The right ventricle receives oxygenated blood from the right atrium (as it contracts). Once the ventricles are full, they contract and the tricuspid valve shuts and the pulmonary valve opens. This makes sense for the tricuspid valve to shut (preventing regurgitation or backwash) while the blood flows through the open pulmonary valve into the pulmonary artery (to the lungs.) I would not have chosen a) or c) for an answer. You can rule out b) for an answer because the papillary muscles contract opening the tricuspid valve. You chose the correct answer, d) because once the ventricles are full they contract causing their respective valves to shut.

Q:i have got a problem with the valve but i have some guy gonna try and clean it next week. i have heard of blanking plates. has anyone used one of these? do they make any difference in the way the car goes ?: Think okorder . Go on line an read: Function EGR Valve before you ruin the engine with a block-off plate.

Q:We live in a four story sixteen unity apartment building. There are two radiators in our apartment. The on in the living room is large and we can't turn it on with out water coming out of the little valve on the end, which I am assuming is there to release excess pressure. It doesn't matter if we leave it on for an hour or two days—water still comes out. It has warped the wood below it.How can I stop this? I would really like to have heat on both sides of my apartment.Thanks!: The little valve needs to be changed with a new one,that valve has a small leather inside and it is to spit out water and air until the leather gets wet ,and then stops, then when the leather gets dried out ,it will do the same thing again and again, This is a auto radiator air bleeding type valve used for many years in radiator heating systems................Ok.......Mel........ Hope this helps you...
