- Q: Why are pig hearts valves used as replacements for damaged heart valves in humans? Are there any complications and are they still used today?
- The tissue is most like ours. Yes, they are still used. They have a low rate of rejection.
- Q: large veins contain one way valves, which keep the blood flowing in one direction. why dont large arteries need similar valves?
- The heart actively pumps blood forward. That keeps it moving in one direction. On the other hand, venous flow is more passive.
- Q: I somehow lost the valve cap to one of my tires. Do stores sell replacement caps? If so, would a place like Sears or VIP be a good place to look? If not, would a bike tire valve cap work?In the mean time, i took a cap off the fullest tire to put on this one(the lowest) was that good or bad idea?

- Q: I have a 1997 ford aerostar and my mechanic just called me and said that the pop off valve needs to be replaced, but it is attached to the line so the hole line has to be replaced to. I want to try to find the pop off valve to see if I can get it b/c he can't find the replacement part, what I need to know is what it looks like. or where it is on an aerostar, because I have 5 more sitting in the driveway and I can look for it.
- 1. the pop off valve is normally located in the compressor so if it over pressures it will relieve some of the pressure. it's not in a line. #2. if it's a 1997 it doesn't have R12. it has R134. the only valve in the line is the port to check pressures and vacuum and recharge it. it could have one of those valves leaking and most can be taken apart and a new schrader valve installed. hope this helps.
- Q: for a big block chevy,best way to adjust valves and rockers
- The running method is a good way to set the valves but you can set them with the engine not running to turn the motor to top dead center the rockers that have got the valves closed you loosen the rocker and spin the push rod kept spinning the push rod and tighten the rocker till you fell a slight resistance on the push rod or it do's not spin freely turn motor over 180 and do the rest this is setting every thing at 0 lash and you will not blow oil all over your engine bay they do make rocker oil stoppers but not had any luck with them. a lot of time ween you set the valves with the motor running and if not done it before you will set them to tight but ether method is a good one. good luck
- Q: does a 1975 chevy pickup 2wd has a proportioning valve? If so how does it work and the signs it is bad? my truck has disc/drums brakes?
- Yes The valve causes your rear brakes too apply before the front brakes .Safety reasons,(If your fronts apply first chances are the rear of the vehicle could come around on you) It utilizes spring pressure and offset valving. There is a rubber button that you must depress to bleed the rear brakes It's an override.
- Q: My husband just found out that one of the heart valves is 100% blocked and the other 3 are 90% or more blocked . He is 78 years old he Is nearly non mobile. What kind of treatment would you suggest?
- A heart valve can't be 100% blocked. The heart simply couldn't function. On the other hand, coronary arteries can be blocked as you described. Normally, 4 vessel disease is treated with bypass surgery. In a high risk patient, angioplasty might be an option. However, if he is not having cardiac symptoms , or if he is thought to be TOO high risk, the option is medical treatment. Sit down for a talk with his cardiologist.
- Q: How hard and expensive is it to replace a pvc valve , hose, filter on 1991 Dodge Caravan 4 cylinder
- THE GUY ABOVE TOTALLY MISSED IT. IT IS VERY SIMPLE TO REPLACE AND SHOULD COST LESS THAN $25.00.
- Q: like they say on 4 strokes you gotta go get valve jobs, and they cost bout 300 they say? well what does the mechanic do? can it be done at home and your just adjusting them?
- i'm 18 and race a crf40r i admire the motorbike. in case you desire to flow extra decrease priced i might decide for 2 stroke. have faith it or not 2 stroke is extra maintence even though it is lots extra decrease priced to rebuild. A 2 stroke on long tracks with enormous sweapers is purely as speedy as a 450 if not speedier. I enjoyed my 250 haha. 450's are somewhat a combat on the song they supply a real undesirable arm pump by using engine breaking. and 250 4 strokes are like driving the previous one hundred twenty five's all you do is shift. in case you may desire to get an rm 250 2 stroke they have the extra appropriate potential bands and have very solid bottomw end.
- Q: My third valve won't move at all. I haven't played my trumpet in a while and I tried to oil it to get it to unstick but it still won't move at all. People say to screw it off but I can only unscrew the little cap at the bottom of the valve where you push in, not the white button at the top. Help please! Thank you so much! =]
- i got here across that Dennis Wick valve oil is a procedures more advantageous ideal to any that I easily have used. you'll locate it on Amazon. If cleansing with dish cleansing soap and heat water would not artwork, alongside with the Dennis Wick oil, I recommend that you're taking it to a restoration shop. be careful at the same time as cleansing now to not get any cork or felt moist. only dip the truly valve section into the water.
