Millions of sperms are deposited into the vagina during sexual intercourse. The sperms make their way through the cervix into the uterus and then on to the fallopian tubes. As they swim along this way their numbers decline. Only a few hundred sperm will get close to the egg. During the trip, sperm prepare themselves to meet the egg by subtle alterations of their heads and movement patterns. Once inside the fallopian tube, the sperm attracts the egg by releasing a chemical. The egg is surrounded by a protective covering called the zona pellucida, which allows only one sperm to penetrate it. Once inside the egg, the head of the fertilizing sperm releases its genetic contents, which fuses with the nucleus of the egg. Fertilisation is now complete. Sperm are able to survive for 2-3 days within the female's reproductive tract. The length of the time that a woman's egg can be fertilized by a man's sperm ranges from 12-24 hours.

Intubation during General Anaesthesia 3D Animation

In breastfeeding, the latch is the moment everything comes together: Your baby takes a big mouthful of your nipple and areola (or "latches on"), begins to suck, and draws out your milk. When your baby has established a good latch, your nipple soreness is minimized and your little one gets the nourishment he needs. How do you pull all that off? First and most important, have faith in yourself and your baby. "Babies are designed to breastfeed," says Emily Pease, R.N., international board certified lactation consultant (IBCLC), of Swedish Hospital's Breastfeeding Center in Seattle. "They are born with instincts that help them find Mom's breast and latch on often with very little assistance. And if problems do come up, there are lots of ways to troubleshoot." Here are more steps to get a good latch right from the start.

Central Line Placement 3D Animation

In caring for patients who are critically ill, access to the central venous circulation is important. Central venous access allows the placement of various types of intravenous (IV) lines to facilitate the infusion of fluids, blood products, and drugs and to obtain blood for laboratory analysis. It is also an essential procedure in patients in whom placement of a line in a peripheral vein is impossible. A central line may be the only means of venous access in such cases.
