Organs on the left side of the body are those that are located towards the left of the vertebral column.
The human body can be vertically divided into two equal halves along the vertical axis.
So, based on their distribution, some organs can be found on the left and some on the right side of the column.
Vital Organs on the Left Side of the Body
- Heart
- Stomach
- Pancreas
- Spleen
- Kidney (left)
- Lung (left)
- Ovary (left in the woman)
- Testis (left one in the adult male)
- Eye (left)
- Ear (left)
- Adrenal gland
- Salivary glands
Heart
- This appears to be at the center of the body in the thoracic cavity between the lungs.
- But most of it is localized to the left of the body’s axis.
- It is situated between the lung and inside the rib cage, ensuring its protection.
Stomach
- The stomach is the prominent organ of the digestive system.
- 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.
- It is both an endocrine and exocrine gland.
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.
Eye
- One of the two eyes is on the left side of the forehead.
- So we call it the left eye, and it helps in vision on the left.
Ear
- One of the ears is on the left side of the head, helping in hearing and body balance.
Adrenal gland
- There are a pair of adrenal glands, each located on a kidney.
- One of them is found on top of the left kidney.
- 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.
Organs on the left side of the body under the ribs
The organs under the ribs are the stomach, pancreas, spleen, left kidney, ovary, and testes.
Organs near the waist
Kidneys, ovaries, testes, adrenal gland, spleen.
I feel a slight heaviness on left side below left rib. Been there a while. I just assumed it’s a hernia. But now I’m wondering if it could be spleen related? Not really painful. But very much aware that it’s not normal like the right side. Any ideas? Thanks
I was pulling some strongly rooted weeds and I felt a pain on the left side directly under neath the edge of my lower ribs. It is increasing in pain. What is it that I’ve hurt?
Nothing serious perhaps.
I’m overweight 70 yrs old when my adult cat gets on my upper left side near my ribs, it’s very tender. I’ve have checked for stones but there are none. What could. Cause the tenderness?
I have tender ribs on left side also have had mild pain in that region under ribs and just below. I am 76 yes old and am overweight. I also suffer constant constipation.
Hi Dan, emailed you the solution. Hope you find it useful.
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.
