Human Body Parts That Start With U

When you think of body parts, what comes to mind? If you’re like most people, the first thing that comes to mind is probably the different organs and muscles in our body. However, did you know several body parts begin with the letter “U”? In this blog post, we’ll look at some of the human body parts that start with “U.” So, without further ado, let’s get started!

Human Body Parts That Start With U

The urinary system is an essential part of the human body. It helps to remove waste products from the body. In the human body, the urethra serves as the conduit which carries urine from the bladder to the outside world. The uterus is a female reproductive organ where a baby grows during pregnancy. The uvula is a small, fleshy projection at the back of the throat. There are many other human body parts that start with “U, “they are as follows:

Ulnar Artery Upper Intestine Urinary System
Ulnar Nerve Ureter Urinary Tract
Ulnar Nerve, Motor Distribution Ureter, In Pelvis Uterine Tube
Umbilical Chord Urethra Uterus
Upper Extremity Bones Urethra, Male  
Upper Extremity Veins Urethral Sphincter Muscle  

Discussion about the Parts

  •       Ulnar Artery: The ulnar artery is one of the main arteries in the human body. It is located in the arm and supplies blood to the forearm and hand. The artery is located on the medial (inner) side of the arm and runs parallel to the ulna, a bone in the forearm. It arises from the brachiocephalic trunk, a large artery that supplies blood to the head, neck, and arms. The brachiocephalic trunk arises from the aorta, the main arterial trunk in the body. The ulnar artery gives rise to several smaller arteries that supply blood to different parts of the forearm and hand.
  •       Ulnar Nerve: This nerve crosses the arm between the shoulder and the hand. It controls the hand muscles that allow us to grip and hold things. Besides providing sensation to the little finger and the half of the ring finger, the ulnar nerve also provides sensation to the thumb. Most people don’t know much about their ulnar nerve until they injure it. A common injury called “hitting your funny bone,” which irritates the Ulnar nerve as it passes through a small opening in our elbow, is called cubital tunnel syndrome. This can cause numbness and tingle in the fingers.
  •       Umbilical Cord: umbilical cord is a challenging and flexible cable that connects your developing baby to your placenta. This remarkable human structure develops during pregnancy and contains two arteries and one vein. At birth, the cord is approximately 22 inches long and is composed of Wharton’s jelly, a gelatinous substance that provides comfort and nutrition to your growing baby. The muscles in your womb (uterus) contract during labor and birth to push the baby out. In the process of the baby passing through the birth canal, these contractions help to guide the parts of the baby’s body — including the head — through the mother’s pelvis.
  •       Upper Extremity Bones: The human skeleton comprises 206 bones, which provide structure and support for the body. The upper extremity bones include the humerus (upper arm bone), the radius and ulna (forearm bones), and the carpals, metacarpals, and phalanges (hand bones). When they work together, these bones can provide a range of motion, including flexion and extension at the elbow, pronation, supination at the forearm, flexion and extension at the wrist, and thumb opposition.
  •       Upper Extremity Veins: Upper extremity veins include the brachial, axillary, and subclavian veins. The brachial vein is a superficial vein that runs down the medial side of the arm from the shoulder to the elbow. One of the main functions of the axillary vein is to drain blood from the armpit (axilla) to other parts of the body. The subclavian vein is a deep vein that runs along the medial side of the clavicle (collarbone) and drains blood from the arm, chest, and head.
  •       Upper Intestine: The upper intestine is a section of the gastrointestinal tract that begins at the stomach and ends at the small intestine. It is responsible for the absorption of food and liquids from the stomach into the bloodstream. A tiny projection called the villi helps in this process. Villi contain small, hair-like protrusions called microvilli. These structures increase the intestine’s surface area to absorb more nutrients from food.
  •       Ureter: In the human body, the ureter is a small tube that connects the renal pelvis to the bladder. It carries urine from the kidneys to the bladder. Urine is produced in the kidneys when blood passes over the organs’ filters, called nephrons. The nephrons extract waste products and water from the blood and create urine. The ureter is approximately 25 centimeters long and about 2-3 millimeters wide.
  •       Ureter, In Pelvis: The ureter is a long, narrow tube that carries urine from the kidney to the bladder. It passes through the pelvic cavity, on either side of the uterus in women. The ureter is about 25 centimeters long and 2 millimeters wide. It has three layers: an inner mucous membrane, a smooth muscle’s middle layer, and an outer fibrous coat. The smooth muscle layer contracts to push the urine down the ureter. The outer coat helps keep the ureter open and allows it to move around quickly inside the pelvic cavity.
  •       Urethra: During urination, urine drains through the urethra into the bladder. In men, the catheter passes through the prostate gland and penis. In women, the catheter passes through the opening of the urethra. Generally, it reaches about 8 inches for men and about 1.5 inches for women. Urine drains from the urethra by compressing the urinary bladder with the pelvic floor muscles. This is the same muscle that stops urination midstream.
  •       Urethral Sphincter Muscle: The urethral sphincter muscle is a muscle located around the urethra that helps control the flow of urine. It is a skeletal muscle, and like all skeletal muscles, it works by voluntary nerve impulses from the brain. The urethral sphincter muscle allows you to stop the flow of urine voluntarily. This will enable people to hold their bladder for short periods when they need to, such as when they are in a public place and don’t want to go to the bathroom. The urethral sphincter can also contract involuntarily when someone coughs or sneezes, which helps prevent urinary leakage.
  •       Urinary System: The urinary system is very important in the human body. It helps to remove waste products from the body, and it also helps to maintain fluid balance. The urinary system consists of several parts, including the kidneys, ureters, bladder, and urethra. The kidneys filter blood and remove waste products from the body. Urinary tubes carry urine from the kidneys to the bladder, and the bladder is a muscle that stores urine until it comes out from the body through the urethra.
  •       Urinary Tract: Urinary tract is responsible for producing, storing, and eliminating urine from your body. There are many parts to it, and they all work together to make it work. As well as filtering blood and producing urine, your kidneys are also responsible for excreting toxins from your system. Once the urine builds up in the bladder, it stays there until it is time to be eliminated. When it’s time to go, urine travels from the bladder through the urethra and out of the body. The entire process depends on a series of muscles and nerves that work together to keep everything flowing smoothly.
  •       Uterine Tube: Uterine tubes, also called fallopian tubes, are two very thin tubes that run from the uterus to the ovaries. Each tube is about four inches long. The tubes help move the egg from the ovary to the uterus. They also help keep sperm and fertilized eggs in place within the uterus. The uterine tubes are part of a woman’s reproductive system. They play an essential role in getting pregnant. There may be a problem with a woman’s uterine tubes if, due to her inability to get pregnant, her doctor performs tests to determine if that is the problem.
  •       Uterus: The uterus is shaped like a pear and is a muscular structure found within the pelvis. Also called the womb, the uterus is where a fetus develops during pregnancy. The uterus consists of two parts: the fundus, the upper portion of the organ, and the corpus, which is the main part. The ovaries are attached to each side of the uterus via the fallopian tubes.


From the list above, you can see human body parts start with U. It’s incredible what our bodies can do and how many different functions and organs we have. We hope this list has been informative and fun for you. Feel free to share this blog with as many friends as possible on social media or in person so that they can learn about these good parts of the body.
