What does zygote intrafallopian transfer involve?
types of assisted reproductive technologies .In gamete intrafallopian tube transfer (GIFT), the eggs and sperm are mixed in a narrow tube, and then deposited in the fallopian tube, where fertilization normally takes place.
What is oscillation in a chest tube?
movement of fluid in chest tube R/T inspiration & expiration
How does fluid flow tube length affect fluid flow?
in many different ways in connection with the thickness of the blood,
Why is the bulb in a thermoniter important?
The bulb in a thermometer increases the sensitivity.When the temperature changes in the bulb, the mercury or other fluid will go up or down the narrow tube. The reason for this is due to change in the volume caused by expansion of the mercury or fluid; as the temperature increases, the volume increases.However, the change in volume may be very small, so by having a narrow tube, any movement caused by expansion will be more visually noticeable.To illustrate this, imagine two tubes containing 10ml of fluid each at 20oC. One tube is 1cm in diameter, the other 0.1cm. By using the equation for the volume of a cylinder we can calculate the height of the fluid in the tubes, (remember that 1ml = 1cm3)In 1cm diameter tube:Volume of fluid = pi x radius2 x height of fluid in tube10cm3 = pi x (0.5cm)2 x height of fluid in tubeHeight of fluid in tube = 10 / ( pi x 0.52 ) = 12.73cmIn 0.1cm diameter tube:Volume of fluid = pi x radius2 x height of fluid in tube10cm3 = pi x (0.05cm)2 x height of fluid in tubeHeight of fluid in tube = 10 / ( pi x 0.052 ) = 1273cmAs can be seen, the height of fluid in the smaller tube is much greater as the same amount of fluid has to fit into a smaller space. Now imagine that for a 1oC change in temperature the fluid expands 1% in volume. So at 21oC the 10ml of fluid expands 1% to 10.1ml (10ml x 1.01 (1%) = 10.1ml). Now we can calculate how much movement this would create in the tubesIn the 1cm diameter tube:Volume of fluid at 21oC = pi x radius2 x height of fluid in tube at 21oC10.1cm3 = pi x (0.5cm)2 x height of fluid in tube at 21oCHeight of fluid in tube at 21oC = 10.1 / ( pi x 0.52 ) = 12.86cmSo the fluid in the 1cm diameter tube has moved:Height at 20oC - Height at 21oC = Movement of fluid12.86cm - 12.73cm = 0.13cmWhilst in the 0.1cm diameter tube the fluid has moved:Height at 20oC - Height at 21oC (calculation not shown) = Movement of fluid1286cm - 1273cm = 13cmAs you can see, the movement in the smaller tube would be much more noticeable than in the larger tube and this would mean that even very small temperature changes could be visualised as the fluid moves a lot further. So that is why the central tube is so small, but why the bulb?In the example just shown both tubes had the same volume of starting fluid, 10ml. But, as you saw, 10ml in a 0.1cm diameter tube requires a tube of over 12 metres, a very impractical size for a thermometer! One way to solve this is to reduce the amount of starting fluid to 0.1ml.In the 0.1cm tube:Volume of fluid = pi x radius2 x height of fluid in tube0.1cm3 = pi x (0.05cm)2 x height of fluid in tubeHeight of fluid in tube = 0.1 / ( pi x 0.052 ) = 12.73cmNow we have a thermometer, which although large, could be used. But, look what happens when we increase the temperature to 21oC. The fluid expands to 0.101ml (=0.1ml + 1%) and the new height of fluid in the 0.1cm diameter tube is:Volume of fluid at 21oC = pi x radius2 x height of fluid in tube at 21oC0.101 cm3 = pi x (0.05cm)2 x height of fluid in tube at 21oCHeight of fluid in tube at 21oC = 0.101 / ( pi x 0.052 ) = 12.86cmThis gives a change in height from 20oC to 21oC of only 0.13cm. We have lost the sensitivity given by the smaller tube.Therefore, to make a sensitive thermometer we need a large volume and a narrow tube. So how do we do this without making a thermometer too big to use? By adding the bulb. The bulb is a lot wider than the narrow tube of the thermometer and is therefore able to hold a larger amount of mercury or fluid. But if the entire tube was the same width as the bulb, any expansion would be difficult to see. So by combining the bulb, with its ability to hold a large volume of mercury or fluid, with the narrow tube, with its ability to cause large movement of fluid for a small amount of expansion, we create a sensitive thermometer.So to give a short answer, the bulb increases sensitivity by increasing the volume of mercury or fluid inside the thermometer causing greater amplification of expansion, or movement, up the narrow tube. So more volume = greater movement = greater sensitivity.The bulb in a thermometer increases sensitivity. It helps determine whether the fluid will go up or down. The bulb helps make a sensitive thermometer and it helps in holding a larger amount of mercury or fluids than the narrow tube.
Is the relationship between the fluid flow rate and the flow tube radius linear or exponential?
exponential
What is the job of the embryonic fluid?
the embryonic fluid is seen in Fallopian tube it helps to move the sperms to the ovary.
What moves to create fluid currents to draw the ovulated egg into the fallopian tube?
fimbriae
Oviduct is another name for which of these?
another name for an oviduct is Fallopian Tube.
Which structure catches the ovum as it leaves the ovary?
Fallopian Tube
Long tube between the ovary and the uterus?
The long tube between the ovary and the uterus is the fallopian tube. There are usually two fallopian tubes in the female body, one for each ovary.
What is the medical term meaning blood in the fallopian tube?
Hematosalpinx is the term meaning blood in the fallopian tubes.
What is left fallopian tube shows peritoneal spill?
The HSG shows that the left fallopian tube is not blocked.
What is the tube connecting the ovary and the uterus?
It's called a fallopian tube. It attached from the ovary to the uterus, it's where the eggs travel through.
What does a fallopian tube has to do with pregnancy?
The fallopian tube is the typical site of human fertilization. It carries the egg from the ovary to the uterus.
What is the function of fallopian tube?
=A tube which allows you to urinate.==The fallopian tube is the tube which connects the ovaries to the uterus. It is along this tube that ova travel. They can sometimes be fertilized in this tube and here to the wall and start to develop. This is known as an ectopic pregnancy.=
What is the Site of fertilization for humans?
Fertilization occurs in the second portion of the fallopian tube ( ampulla of the fallopian tube )
Where's the fallopian tube in a womans sex cells?
The fallopian tube is on the other side of the uterus in a woman's sex cell.
