What is oogenesis? Oogenesis is a type of gametogenesis. It is the process of producing female gametes, once sex determination of the embryo has occurred. The presence of the SRY gene on the Y chromosome leads to male gonad formation and spermatogenesis, while female gonad development is the âdefault stateâ.
One type of twist or kink is called a small bowel obstruction. This usually happens after a patient has had an abdominal operation like appendectomy, hysterectomy, or colon removal which leads to scar tissue or adhesions developing in the abdomen. The intestines can be come twisted, kinked, or obstructed around this scar tissue. This condition, called a small bowel obstruction, may require surgery for treatment in 20% of patients. Small bowel obstruction can also occur as the result of a hernia. Another type of intestinal twist is called a volvulus. This usually occurs in the colon, where a segment of the colon rotates 180 degrees like a roller coaster loop. This causes a blockage of the colon and may pinch off the blood supply to the colon.
These lumps, called granulomas, are too small to see or feel. They can form anywhere on the inside or outside of the body and can cause permanent scar tissue. They often form in the lungs, lymph nodes, liver, skin, or eyes. Sarcoidosis may affect how an organ works. For instance, if it's in your lungs, you may be short of breath. For every 10 people who get sarcoidosis, 2 or 3 will have permanent lung damage. A small number of people may end up with chronic sarcoidosis, which can last for years.
