Ductus deferens
The oral cavity contains the teeth and tongue. It is the opening through which food enters the body and where the process of digestion begins.
Increasing the size of the thoracic cavity allows for the lungs to expand, creating negative pressure inside the chest cavity. This negative pressure pulls air into the lungs, facilitating inhalation. Additionally, it helps to maintain airflow and efficient gas exchange in the respiratory system.
Air enters through your nose or mouth to your air sacs.
A species that enters an environment where it has not lived before is called an invasive species. These species can have a negative impact on the native ecosystem by outcompeting native species for resources and disrupting the balance of the ecosystem.
The respiratory system contains the septum, which divides the nasal cavity into two chambers. This structure helps to direct airflow and aid in the filtration and humidification of air as it enters the body.
Air from the nasal cavity enters the superior portion of the pharynx called the nasopharynx.
Hernia, hiatus: Protrusion of the stomach up into the opening normally occupied by the esophagus in the diaphragm, the great dome of muscle that separates the thoracic (chest) cavity from the abdomen.
Surgical correction of an intussusception is done with the patient under general anesthesia. The surgeon usually enters the abdominal cavity by way of a laparotomy, a large incision made through the abdominal wall. The intestines.
Stomach ulcers occur when the thick layer of mucus that protects the stomach lining from stomach acids is reduced. They are easily cured medically, but can become serious without treatment. A hole in the stomach is called a perforation. It can result in the membrane that lines the abdominal cavity becoming inflamed, a condition called peritonitis, if bacteria, bile, or stomach acid enters the abdominal cavity. Perforation of the stomach is a medical emergency that can be life threatening.
The expulsion of a mature oocyte into the peritoneal cavity is known as ovulation. During ovulation, the mature egg is released from the ovarian follicle and enters the abdominal cavity. The fimbriae of the fallopian tube help to capture the egg and transport it into the tube for potential fertilization by sperm.
Through nose.
The opening between the mouth and the esophagus is called the pharynx.
Diaphragmatic breathing, abdominal breathing, belly breathing or deep breathing is breathing that is done by contracting the diaphragm, a muscle located horizontally between the chest cavity and stomach cavity. Air enters the lungs and the belly expands during this type of breathing.
Pressure on the lung leading it to collapse
Normal anatomyDuring development, the scrotal cavity in boys is connected to the abdominal cavity via a structure called the processus vaginalis. The processus vaginalis usually closes at birth, or soon after.IndicationsWhen the processus vaginalis does not close, or closes after fluid from the abdomen has become trapped in the scrotal cavity, it is called a hydrocele. The canal (inguinal canal) between the abdominal cavity (peritoneum) and the scrotum remains open. Fluid from the peritoneum enters the canal and the scrotum, and causes swelling of the scrotum. In some cases, bowel can also pass through the processus vaginalis into the scrotum. This is called an inguinal hernia. If a hydrocele persists past the first six to 12 months of life, it should be surgically repaired. Inguinal hernia in infants is usually repaired within the first three months of life. It is sometimes difficult to distinguish a hydrocele from an inguinal hernia on exam.ProcedureWhile the baby is deep asleep and pain-free (general anesthesia), an incision is made just above the groin. The open canal between the abdominal cavity and scrotum (inguinal canal) is repaired, the fluid is removed from the scrotum, and the incision is closed.AftercareSurgery usually completely corrects the defect, and the long-term prognosis is quite excellent. Hydrocele repair is done on an outpatient basis and recovery is usually brief. Most children can return to normal activity within about four to seven days.Reviewed ByReview Date: 09/03/2010Linda J.
