Fertilization and Implantation in human
Fertilization and Implantation in human samer kareem 3,162 Views • 3 years ago

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.

Acufene Orecchio Sinistro, Fischio Nelle Orecchie Dopo Discoteca, Rumore Nelle Orecchie Da Sdraiati---- http://acufeni-cura.plus101.com/ --- Che cos'è l'acufene? Ti svegli nel mezzo della notte sentendo strani rumori? Sì, può far paura, specialmente se non capisci da dove arrivano. Ora pensa che questi rumori vengono da dentro di te. La maggior parte delle persone rimarrebbe sbalordita di una simile affermazione. Molti di noi non sanno neanche che i nostri organi interni possono produrre rumore. Vediamo se hai effettivamente udito tali rumori oppure no, e se li hai uditi, da dove provengono. Innanzitutto, lasciati dire - si, li hai sentiti. No, non sono il risultato di una mente creativa che si è sognata tutto. Ma detto ciò è anche vero che non c'è una fonte da cui provengono tali rumori. Allora che cos'è? Confuso? E' un classico caso di acufene. Che cos'è l'acufene? Quello che hai vissuto la notte scorsa (o ti sei appena svegliato e hai acceso il computer) è un classico caso di acufene. Si tratta di un disturbo medico in cui la persona sente ogni tipo di strani scricchiolii, ronzii, brusii, fischi o sibili all'orecchio. Ciò che è così preoccupante di questa malattia è che non c'è una sorgente di tali rumori. A peggiorare il tutto è che nessun altro li sente. Francamente queste persone non possono essere biasimate. Se non puoi vedere da dove proviene il suono e continui a sentirlo ti riempi di agitazione. Nell'acufene i suoni uditi dalla persona sono di fatto percezioni. Visto che non c'è una fonte reale sono spesso definiti come "rumori fantasma". Ti aiuta sapere che circa l'8% della popolazione degli USA soffre di acufenis? Forse no, ma almeno sai che non sei l'unico a sentire questi strani rumori. Che cosa causa questi rumori? Sicuramente vuoi sapere perchè senti tali rumori. ma prima di conoscere questo dovresti sapere che l'acufene non è una malattia vera e propria. E' il sintomo di un problema dalla radice profonda da qualche parte nel tuo corpo. L'unico modo per sbarazzarsi per sempre degli acufeni è seguire un approccio di cura olistico. Utilizzando un trattamento multidimensionale per l'acufene, affrontiamo tutti i fattori che lo causano,eliminando alla radice questi elementi scatenanti. Questa è l'unica strada per ottenere una libertà definitiva dall'acufene. inserisci ora: http://acufeni-cura.plus101.com

ALPHA & BETA BLOCKERS
ALPHA & BETA BLOCKERS samer kareem 4,104 Views • 3 years ago

Alpha blockers relax certain muscles and help small blood vessels remain open. They work by keeping the hormone norepinephrine (noradrenaline) from tightening the muscles in the walls of smaller arteries and veins, which causes the vessels to remain open and relaxed. This improves blood flow and lowers blood pressure.

Emphysema
Emphysema samer kareem 3,116 Views • 3 years ago

Emphysema gradually damages the air sacs (alveoli) in your lungs, making you progressively more short of breath. Emphysema is one of several diseases known collectively as chronic obstructive pulmonary disease (COPD). Smoking is the leading cause of emphysema. Your lungs' alveoli are clustered like bunches of grapes. In emphysema, the inner walls of the air sacs weaken and eventually rupture — creating one larger air space instead of many small ones. This reduces the surface area of the lungs and, in turn, the amount of oxygen that reaches your bloodstream. When you exhale, the damaged alveoli don't work properly and old air becomes trapped, leaving no room for fresh, oxygen-rich air to enter. Treatment may slow the progression of emphysema, but it can't reverse the damage.

Combitube Insertion
Combitube Insertion Doctor 10,513 Views • 3 years ago

The Combitube is a twin lumen device designed for use in emergency situations and difficult airways. It can be inserted without the need for visualization into the oropharynx, and usually enters the esophagus. It has a low volume inflatable distal cuff and a much larger proximal cuff designed to occlude the oro- and nasopharynx.

If the tube has entered the trachea, ventilation is achieved through the distal lumen as with a standard ETT. More commonly the device enters the esophagus and ventilation is achieved through multiple proximal apertures situated above the distal cuff. In the latter case the proximal and distal cuffs have to be inflated to prevent air from escaping through the esophagus or back out of the oro- and nasopharynx.
