Body Organs

The liver, an organ found in all vertebrates, is the largest organ in the human body. It is a spongy, reddish brown glands that lies just below the diaphragm in the abdominal cavity. It serves to metabolize carbohydrates and store them as glycogen, metabolize Lipids (facts, including cholesterol and certain vitamins) and proteins, manufacture a digestive fluid, bile; filter impurities and toxic and destroy old, worn-out red blood cells. Two large lobes, the right and the left, make up most of the liver; attached to the right lobe are the smaller quadrate and caudate lobes. The lobes are made up of lobules, six sided cells arranged in sheets one cell thick that are closely arrange around in sheets one cell thick, that are closely arranged around blood vessels, blue ducts, lymph vessel and nerves. Certain reticuloen dothelial cells (Kupffer cells) line these lobules and play a role in immunity. Approximately three sides of each cell are in contact with a blood vessel, and three are adjec...

The pelvis, so called from its resemblance to a basin ( L. pelvis ), is stronger and more massively constructed that either the cranial or thoracic cavity; it is a bony ring, interposed between the lower end of the spine, which it supports, and the lower extremities, upon which it rests. It is composed of four bones; the two ossa innominata , which bound it on either side and in front, and the sacrum and coccyx, which complete it behind. The pelvis is divided by an oblique plane passing through the prominence of the sacrum, the linea illio-pectinea, and the upper margin of the symphysis pubis into the false and true pelvis. The false pelvis is the expanded portion of the pelvic cavity which is situated above this plane. It is bounded on each side by the ossa ilii; in front it is imcomplete, preventing a wide interval between the spinous processes of the illia on either side, which is filled up in the recent state by the parities of the abdomen; behind, in the middle line, is a dee...

The uterus, or womb, is quite an amazing organ. Pear-shaped in appearance, and testing on its small end (the cervix) in the center of a woman’s pelvis, it houses and protects a fetus from implantation until birth. As the fetus grows during pregnancy , the uterus expands tremendously – from the size of a fist into a huge, muscular bag filling the woman’s entire abdomen. That bag can hold not only a full term baby, but a quart of fluid and a one-pound placenta besides. The Menstrual Cycle Every month, if the woman is not already pregnant, the inner lining of the uterus (the endometrium) goes through a process of renewal and preparation known as the menstrual cycle. Basically, the menstrual cycle is the way the woman’s uterus prepares to receive and nourish a fertilized ovum. The inner lining of the uterus thickens and grows, and the structure of its blood vessels changes. If an ovum does become fertilized that month and implants in the uterine lining, the uterus keeps its lining to no...

A long, thin organ in humans, the pancreas has both digestive and endocrine functions and for this reason contains two completely different types of cells. Measuring about 12-15 cm (5-6 in) long. It is nestled within the curve of the duodenum and stretches transversely across the posterior abdomen behind the stomach, in front of the spine and aorta. The digestive, or exocrine, cells of the pancreas consist of a number of small lobules, or acinar cells, joined together into small ducts that, in turn, join the two major ducts of Santorini and Wirsung, which empty through small muscular openings into the duodenum. The lobules contain numerous cells that secrete pancreatic secretions containing electrolytes and three important digestive enzymes, typsin, amylase, and lipase. These enzyme digest proteins, split fat, break down highly polymerized nucleic acids, and break down polysaccharides such as starch, amylopectin, and glycogen. The protein splitting enzyme enterokinase is mixed with it,...

Muscles of the Neck The muscle of the neck may be arranged into groups corresponding with the region in which they are situated. These groups are nine in number: Superficial cervical region Depressors of the Os Hyoides and Larynx Elevators of the Os Hyoides and Larynx Muscle of the Tongue Muscles of the Pharynx Muscles of the Soft Palate Muscles of the Anterior Vertebral Region Muscle of the Lateral Vertebral Region Muscle of the Larynx The muscle contained in each of these groups is the following: 1.
