What is the size of a ventricles of heart?
The ventricles of a heart is about 87 Grams. There is the smallest ventricle.
According to research by Waite and Ernst (The Trapdoor Springfield), your 1873 was manufactured in the last quarter (Oct/Dec) 1873. The number '25' on the stock is probably a rifle rack number so that it could quickly be placed back where it belonged in an arms room.
What is the size ratio of heart to body comparing baby to adult?
percentage wise an infants heart is larger at birth than that of an adult.
What is the depressed white scar of the heart called?
there are several landmarks on the heart, making your question a little unspecific, but I think you may be referring to the "sulcus terminalis" where the Sinusal node is.
Why do many veins have flap-like valves in them?
It is to allow the blood to flow in one direction - towards the heart, it prevents back flow.
its very good for tui and hun to exrete so they can pass the test test test test test test test test test
How do you prevent your side walls from buckling from frost heaves?
Most older inground pools are made to not buckle out from the water pressing against the walls-as opposed to buckling in. We had sever buckling on several panals over the years and came up with a simple way to repair AFTER DRAINING POOL ABOUT 4 FEET DOWN:
1. break up concrete above buckled panel (Home depot electric jackhamer $60 for 4 hours-easy to use)
2. Dig down apprx 3' to the concrete sill (its surrounding the entire inground pool) Clean out enough width so you can stand in hole and work.
3. find the triangle looking brace that holds the wall from buckling out-you'll notice the metal panel is not bolted to it and is probable 2 inches or more buckled away from it. Clear all dirt 3 feet to left and right of metal triangle(you may need to break more concrete) all the way down to concrete sill.
4. remove white plastic cap that covers your vinyl liner in area above buckle and pull or work out the liner from the groove it sits in in THAT AREA ONLY. You can stretch out the liner away from the wall with a plastic whiffle ball bat or someone can hold it out for you.
5. drill 3 holes (top middle bottom) in triangle brace and all the way through the metal panel pool wall into the pool-(have someone hold out liner so it doesn't get torn and also hold hand under where drill will come through to catch metal shavings)
6. Buy a 2' long by 1/8" thick aluminum yardstick looking thing (Home depot-$5 near all the metal rods and bracings isle)
7. While holding that aluminim bar in pool-under the liner of course- cover the 3 holes and mark it with a pencil pushed from the already drilled holes on the outside. Pick up the bar and drill matching 3 holes.
8. hold aluminum bar in place and push each of 3 1/2"x8" round head galvanized lag bolts (threaded from top to bottom-some home depots only sell bolts threaded at very end) You may have to make the holes in aluminum bar wider to accomodate the squared area near rounded heads of bolts so it sits in better)
9. Push bolts through till they enter through steel triangle support-use galvanized 1/2" washer and nut and tighten each till pool wall touches the steel triangle support.
10. Cover all with duct tape, and then put liner back in groove, cover with the white plastic cap-fill in hole-pour new concrete-DONE!!!!-I've done this in several areas of our 30+ year old inground pool and it works GREAT!!!
Depends on what type of furnace you have but it sounds like 1.a wire from the thermostat is shorted, 2.the thermostat is stuck itself or 3. the main gas valve is stuck. Try turning the power off to the furnace next disconnect the wires leading to the gas valve if this stops it check 1 and two if this doesnt stop it then it is number 3
A test valve is a specialized valve used to facilitate testing and maintenance of piping systems, particularly in hydraulic and pneumatic applications. It allows for the safe measurement of pressure and flow without requiring the entire system to be shut down. Test valves can also help isolate sections of a system for troubleshooting, ensuring operational efficiency and safety. They are commonly found in industrial, commercial, and residential systems.
The main chambers of the heart include the left and right atria, and the left and right ventricles. The atria are the upper chambers that receive blood, while the ventricles are the lower chambers responsible for pumping blood out of the heart. The right side of the heart handles deoxygenated blood, sending it to the lungs, while the left side manages oxygenated blood, distributing it to the rest of the body. This coordinated function is essential for maintaining effective circulation and overall cardiovascular health.
Why is a valentine heart not the shape of a human heart?
i am guessing it isn't the same shape so it is more appealing to the eye, and not all gross looking like the real human heart,
Actually if you see at Valentines the heart refers to the lips. Kissing is the shape of the lips, and the lips is used for kissing. Our Lips has become the symbol image for love because kissing is what we use our lips for. Kissing is the actual bond to true love between a couple rather than sex.
index then right then left of index in triangle shape then little then insert all the way then thumb and insert close fist immediately when in to avoid damage make sure to cut your nails and wash ur hands and dont scratch the linning its fragile and bleeds heavily trust me!cough.<>uncomfortable silence.<> push in and out tadahhh finger her under and in while you fisting!
What happens when a donor heart becomes available?
When a heart becomes available and is approved for a patient, it is packed in a sterile cold solution and rushed to the hospital where the recipient is waiting.
Can Sudafedrine affect blood pressure and heart rhythm?
Yes it can. If I remember rightly it can make your heart beat faster. It can interact with blood pressure medications.
What cause heart sounds S3 and S4?
S3 heart sound is heard after the S2 heart sound (the sound made by the closure of the aortic and pulmonary valves following systole). It therefore happens in early-mid diastole, when the ventricles are beginning to fill.
The sound is caused by a vibration of the ventricles as they encounter blood flow. Though an S3 may be normal in children and young adults, in other populations it may indicate a pathology in 1) a higher than usual amount of blood returning to the ventricle (such as in hypervolemic states), or 2) a stiff ventricle that's more prone to reverberation (e.g. remodeling secondary to heart failure) .
S4 is also due to a vibration in the ventricle wall but occurs later in diastole, when contraction of the atrium forces the final amount of blood into the ventricles. The vibration occurs because the ventricle is too full to contain the additional blood. This can occur in pathologic states such as ventricular hypertrophy.
Is there an advantage to having an M1911A1 Commander rather than a standard size M1911?
The only advantage to using a 4.25" bbl is that you have less gun to hide! As the Commander uses an aluminun frame, it is lighter, but recoil seems to be about the same due to the dual-springs in the commander. I shoot a commander about as well as I do a full-size govt. Go with what you are comfortable with! Update: Not all commanders have alloy frames; The weight is still less than a full government model, as the dust cover, barrel and upper receiver are shorter. The lower receiver grip and magazine size are identical however. I own all three varieties, and prefer the commander as a "carry" weapon; It is a good balance between size and reliability. Officer's Models can be very difficult to reliably tune. Government Models are just bulky enough that a commander makes a nice middle-ground between the two.

Correction to above: The Colt Commander (and similar sized pistols from other makers) use the same size frame in all respects as the Colt Government Model and mil-spec M1911A1 pistols. The dust cover is the same length. It is only the slide assembly which is shorter.
A gulp valve sense a change of vacuum in the intake manifold. The gulp valve is intended to stop the air flow over the exhaust valves when a rich mixture is added to the system, i.e. whenever you let up on the gas pedal. If the gulp valve does not operate correctly, then this rich mixture would hit the exhaust manifold with the forced air and explode in the exhaust system.
