  • The gut up to the esophagus travels through the center of the body.
  • But at the point of the stomach, this gut moves to the left side of the axis, as seen in the picture above.

Thus, the stomach is positioned to the body’s left in the abdominal cavity.

Pancreas

  • This is the organ present near the stomach bottom, as seen in the image below.
  • This pancreas is a large mass of glands with a leaf-like shape.

Its exocrine function helps in digestion by the release of digestive enzymes.

By its endocrine function, it controls blood glucose levels.

Spleen

  • This is a dark purple organ located on the left side near the stomach in the abdominal cavity.
  • It performs functions like the formation and destruction of blood cells, storage of blood, and also immune.
  • Old red blood cells are mostly destroyed after 120 days of their lifespan.

One of the organ pairs is located on the left side.

Kidney

  • As you might have known, there is a pair of kidneys in our body.
  • One is located on the left side of the vertebral column in the hip region.

The other is on the right side and is connected to the urinary bladder through the left ureter.

Lung

  • There are a pair of balloon-like structures with air in them.
  • One is located on the left side and is part of the respiratory system.

It helps in the exchange of gasses in the body from the air.

Ovary

  • A pair of ovaries are located on each side of the body of the woman.
  • They help in the production of ova, the female gamete.

Testes

  • On the left side of the body, one of the testes is present in the scrotum. 
  • It helps in the formation of sperms, the male gametes.

  • This gland releases adrenaline, a neurotransmitter, and also corticosteroid hormones.

The corticosteroids include glucocorticoids and mineralocorticoids.

Salivary glands

  • In the mouth region, there are three pairs of salivary glands.
  • Each jaw, cheek, and chin have one of the pairs.
  • The three salivary glands are the parotid, sublingual, and submandibular glands.
  • So one of the parotic glands, sub-mandibular, is located on the left side of the body. Please check the image below.

The left parotid gland is towards the left ear, while the left sub-mandibular gland is towards the left mandible jaw curve.

These salivary glands secrete saliva, a watery secretion.

This keeps the mouth moist and clean. Saliva has an enzyme amylase.

This amylase digests the carbohydrates in the mouth to a small extent.

Few organs are present along the vertical axis of the body.

These include the uterus, intestine, trachea, esophagus, and urinary bladder.

Further, parts of a few organs are on the left side as the descending colon of the large intestine, portions of the small intestine, lymphatic vessels, and lymph nodes.

  3. How do you tell if you have Kidney stones? I am hurting in the lower back area, I have been given a muscle relaxer, but it isn't helping to much. I am now wondering if I might have kidney stones. I have had problems with lower back injuries in the past. so there isn't much difference for me. I will contact my doctor again tomorrow and see what he might want to do. I am 70 yrs old, never had any of these problems, and I am overweight.
