5. Abdominal quadrants vs 9 regions-names, organs in each & purpose

Research: Abdominal quadrants Vs 9 Regions names and organs in each and & purpose.

The abdomen is subdivided into four quadrants, this is established by using one medial sagittal plane and one transverse plane that passes through the umbilicus at right angles. According to Libretext (2023), these quadrants are labeled using their location such as the upper right quadrant, lower right quadrant , upper left quadrant and lower left quadrant. The upper right quadrant consists of the right portion of the liver, gall bladder, right kidney, a portion of the stomach ascending and transverse colon and a small amount of the small intestines (Libretext, 2023). In the lower right quadrant, you will find the cecum, appendix, part of the small intestine, the right female reproductive organs and the urethra (Libretext, 2023). In the upper left quadrant, you will locate the left portion of the liver the larger area of the stomach, pancreas, spleen, left kidney, transverse, and descending colon, and parts of the small intestine (Libretext, 2023). The left lower quadrant consists of the larger portion of the small intestine, the left female reproductive organs, ureter, and parts of the large intestines (Libretext, 2023). This division of the abdomen was formulated to help physician in identifying what organs and tissues are involved in a disease when individuals complain about pain in the abdomen (Libretext, 2023).

Saladin (2021), states that the abdomen can also be divided into nine regions which entails four line that mimic tic-tac-toe. This is achieved when each vertical line also called midclavicular line because it passes through the midpoint, of the clavicle (Saladin 2021). The superior horizontal line called the subcostal line because it connects the inferior borders of the lowest costal cartilages (Saladin 2021). The inferior horizontal line is called the intertubercular (connecting the tenth rib on each side to the inferior end of the sternum) (Saladin 2021). The inferior horizontal line is called the intertubercular line because it passes from left to right between the tubercules of the pelvis two points of bone (Saladin 2021). The three lateral region of this grid from upper to lower are the hypochondriac, lumbar, inguinal region (Saladin 2021). The three medial from upper to lower are the epigastric, umbilical, and hypogastric region (Saladin 2021). The right hypochondriac region contains the right portion of the liver the right kidney, gallbladder and parts of the small intestine while the left hypochondriac region contains parts of the spleen, the left kidney part of the stomach the pancreas and parts of the colon (Saladin 2021). The epigastric region contains majority pf the stomach part of the liver part of the pancreas, part of the duodenum, part of the spleen and the adrenal glands (Saladin 2021). The right lumbar region consists of the descending colon the left kidney and part of the spleen (Saladin 2021). The umbilical region has the umbilicus, the duodenum, the jejunum, ileum, transverse colon, and bottom portions of both the left and right kidney (Saladin 2021). The right iliac contains part of the appendix, cecum, and right iliac fossa (Saladin 2021). The left iliac consist of the descending colon, sigmoid colon and left iliac fossa. While the hypogastric region contains the bladder, sigmoid colon, anus, uterus, ovaries, and prostate in males (Saladin 2021).

Critical thinking

It is important to be able to locate and identify area of our body so as to be able to communicate effectively issues that may arise. I had an experience summer of 2016, where for three full days I suffered from horrific pain in my hypogastric region. On the third day after going into seizure and had to be rushed to the hospital I was told I had an ovarian cyst that had rupture and I had undergo an emergency operation. Had I known what organs was in the areas I was experiencing the pain I would have taken it more seriously and went to get medical help before passing out.

When talking about DNA which stands for deoxyribonucleic acid and RNA which stands for ribonucleic acid having things in common but are much different when it comes down to the science of it.


DNA is a long molecule like a thread in our bodies and human cells can have 46 molecules of DNA (Saladin, 2021). DNA is also like a spiral staircase you might see in a fancy or old house. It twists around each other. This is called a double helix. Each DNA molecule has two purines and two pyrimidines. They need to be paired together for this all to work. Purines consist of adenine and guanine and pyrimidines consist of cytosine and thymine. Adenine goes with thymine and guanine with cytosine (Saladin, 2021). This is like RNA but minus the thymine. RNA does not contain thymine instead it carries uracil which sometimes pairs with the adenine (Saladin, 2021). These are called nitrogenous bases.

DNA needs help from RNA to produce proteins which is one of RNA purpose. There are many types of RNA called messenger mRNA, ribosomal rRNA, transfer tRNA, and noncoding ncRNA (Saladin, 2021). DNA synthesis the protein where RNA instructs the DNA and assembles the proteins (Saladin, 2021). RNA is much smaller than DNA. RNA is usually unpaired unlike DNA which is paired meaning that RNA is not a double helix. Another difference is DNA stays in the nucleus and cannot leave where RNA leaves the nucleus and works mainly in cytoplasm (Saladin, 2021).

Critical Thinking

I enjoyed this topic learning the similarities and differences of both DNA and RNA. Whenever I heard the word DNA in the past all I knew was it makes up our genes and who we are. I was not familiar with RNA at all. DNA is like the boss but is nothing without the help of RNA. DNA needs RNA and vice versa. The book calls RNA a smaller cousin to DNA but DNA is nothing without RNA. Like DNA, RNA can also sometimes have a double helix but usually are single stranded. This grew my knowledge immensely in the subject of DNA and RNA and there purpose in the bodies.
