The abdominal organs may be classified as solid organs or hollow organs. The solid organs are the liver, pancreas, spleen, kidneys, and adrenal glands. The hollow organs of the abdomen are the stomach, intestines, gallbladder, bladder, and rectum. [6] In the thoracic cavity, the heart is a hollow, muscular organ. [7]
Lung parenchyma showing damage due to large subpleural bullae. Parenchyma (/ p ə ˈ r ɛ ŋ k ɪ m ə /) [1] [2] is the bulk of functional substance in an animal organ or structure such as a tumour. In zoology, it is the tissue that fills the interior of flatworms. In botany, it is some layers in the cross-section of the leaf. [3]
The celiac plexus, also known as the solar plexus because of its radiating nerve fibers, [1] is a complex network of nerves located in the abdomen, near where the celiac trunk, superior mesenteric artery, and renal arteries branch from the abdominal aorta.
This article contains a list of organs in the human body. It is widely believed that there are 79 organs (this number goes up if you count each bone and muscle as an organ on their own, which is becoming a more common practice [1] [2]); however, there is no universal standard definition of what constitutes an organ, and some tissue groups' status as one is debated.

In anatomy and zoology, the cortex (pl.: cortices) is the outermost, otherwise known as superficial, layer of an organ. Organs with well-defined cortical layers include kidneys, adrenal glands, ovaries, the thymus, and portions of the brain, including the cerebral cortex, the best-known of all cortices. [1]
The peritoneum, by virtue of its connection to the two (parietal and visceral) portions, gives support to the abdominal organs. The peritoneum divides the cavity into numerous compartments. One of these the lesser sac is located behind the stomach and joins into the greater sac via the foramen of Winslow . [ 1 ]
It is a small organ attached to the large intestine in the lower right side of the abdomen. Anatomists and medical professionals have traditionally considered the appendix a vestigial organ. Later research suggests that it may have an immunological function. [13] On the dorsal aspect of the abdominal cavity, there are two bean-shaped organs.
The glia limitans, or the glial limiting membrane, is a thin barrier of astrocyte foot processes associated with the parenchymal basal lamina surrounding the brain and spinal cord. It is the outermost layer of neural tissue , and among its responsibilities is the prevention of the over-migration of neurons and neuroglia , the supporting cells ...
