arteria ovarica
The arteria ovarica, also known as the ovarian artery, is responsible for supplying oxygenated blood to the ovary in females.
It originates from the abdominal aorta, usually below the renal artery.
Found within the suspensory ligament of the ovary, it is positioned anteriorly to the ovarian vein and ureter.
The ovarian arteries are paired structures that typically arise from the abdominal aorta at the level of L2.
From there, the artery travels within the suspensory ligament of the ovary, entering the mesovarium.
Anastomosis with the uterine artery in the broad ligament is possible.
It gives small branches to both the ureter and uterine tube.
Some branches unite with the uterine artery, while others continue on the round ligament of the uterus, extending through the inguinal canal to the integument of the labium majus and groin.
In certain cases, around 20%, the ovarian arteries may arise from the renal arteries or other sources such as adrenal, lumbar, or internal iliac arteries.
Besides supplying blood to the ovary, the ovarian artery also provides blood to the uterus.
During pregnancy, the ovarian arteries can enlarge to increase uterine blood supply.

Pro Tips:
1. The ovarian artery, also known as arteria ovarica, is a blood vessel found in female bodies that supplies oxygenated blood to the ovaries, helping them function properly.
2. The arteria ovarica is a small branch of the abdominal aorta, one of the main arteries in the human body responsible for distributing oxygen-rich blood to various organs.
3. Interestingly, the arteria ovarica has a significantly smaller diameter compared to other major arteries. This is because the ovaries do not require as much blood flow as other organs, such as the heart or brain.
4. In some cases, the arteria ovarica can exhibit anatomical variations, where its branches may differ slightly in their pathways or branching patterns. These variations are relatively rare and may occur in a small percentage of the population.
5. The arteria ovarica plays a vital role in reproductive health, as it not only supplies blood to the ovaries but also carries hormones that regulate the menstrual cycle and the release of mature eggs during ovulation.
1. Overview Of The Ovarian Artery In Females:
The ovarian artery is a vital component of the female reproductive system, responsible for supplying oxygenated blood to the ovary. This artery ensures the ovaries receive an adequate blood supply, allowing them to function optimally in various reproductive processes. Without the ovarian artery, the ovary would be deprived of vital nutrients and oxygen, leading to impaired fertility and reproductive health in women.
2. Origin And Location Of The Ovarian Artery:
The ovarian artery originates from the abdominal aorta, specifically below the renal artery. Positioned within the suspensory ligament of the ovary, it lies anteriorly to the ovarian vein and ureter. This strategic location ensures the arterial blood flow is directed towards the ovary, providing essential nutrients and oxygen required for its physiological processes.
3. Anatomy Of The Ovarian Artery Within The Suspensory Ligament:
The ovarian artery runs through the suspensory ligament of the ovary and then enters the mesovarium, which provides support for the ovary. This anatomical configuration has a critical role in protecting the delicate ovarian artery and maintaining its position during reproductive cycles. Additionally, within the suspensory ligament, the ovarian artery can also connect with the uterine artery in the broad ligament. This creates a network of blood vessels that further ensures the adequate blood supply to the ovary.
4. The Paired Structure Of The Ovarian Arteries:
The ovarian arteries are paired structures that originate from the abdominal aorta, typically at the level of L2. This bilateral arrangement ensures proper blood supply to both ovaries. Adequate blood supply is crucial for the optimal functioning of the reproductive system.
5. Route Of The Ovarian Artery From The Aorta To The Mesovarium:
After emerging from the abdominal aorta, the ovarian artery travels within the suspensory ligament of the ovary and continues on to enter the mesovarium. This carefully orchestrated path allows the artery to efficiently deliver oxygenated blood to the ovary, ensuring its optimal functioning.
6. Possible Anastomosis With The Uterine Artery:
In some cases, the ovarian artery may anastomose or connect with the uterine artery within the broad ligament. This collateral circulation between the two arteries establishes additional pathways for blood supply to the ovary and uterus. This connection is important in situations where there is compromised blood flow through one of the arteries, ensuring that the organs still receive an adequate blood supply for their functions.
7. Branches Of The Ovarian Artery To The Ureter And Uterine Tube:
The ovarian artery is responsible for supplying blood to various structures within the reproductive system. It gives rise to small branches that specifically provide blood to important reproductive structures such as the ureter and uterine tubes. The ureter and uterine tubes play vital roles in female reproduction, and it is crucial for them to receive the necessary nutrients and oxygen for their physiological functions.
8. Connection Between The Ovarian Artery And The Uterus:
One branch of the ovarian artery passes on to the side of the uterus and unites with the uterine artery. This connection between the two arteries ensures the uterus also receives a blood supply from the ovarian artery.
The uterus is a vital organ in reproductive processes such as menstruation, implantation, and pregnancy.
The arterial connection between the ovarian artery and the uterus ensures the uterus has access to the necessary oxygen and nutrients to support these processes.
- The ovarian artery branches to reach the uterus.
- It connects with the uterine artery to provide blood supply to the uterus.
This connection is crucial for supplying oxygen and nutrients to support reproductive processes.
9. Offsets Of The Ovarian Artery To Other Areas:
Apart from supplying blood to the ovary and uterus, the ovarian artery also sends offsets to other areas. These offsets travel along the round ligament of the uterus, pass through the inguinal canal, and ultimately reach the integument of the labium majus and the groin. These blood vessels play a role in the blood supply to these areas, which may impact their physiological functions.
10. Alternative Sources Of The Ovarian Artery:
While the ovarian artery typically arises from the abdominal aorta, there are instances where it can have alternative sources. In approximately 20% of cases, the ovarian artery can originate from the renal arteries. Additionally, it may also arise from the adrenal, lumbar, or internal iliac arteries. These alternative sources ensure that blood supply to the ovary is not compromised even if there are variations in the normal anatomy.
11. Functions Of The Ovarian Artery In Supplying The Ovary And Uterus:
The ovarian artery plays a crucial role in supplying oxygenated blood to the ovary and uterus. This blood supply is essential for nourishing these organs and facilitating the reproductive processes. The ovaries receive the necessary oxygen and nutrients to support the growth and development of eggs, while the uterus receives blood for thickening the endometrium and supporting fetal growth during pregnancy.
12. Changes In The Ovarian Artery During Pregnancy:
During pregnancy, the ovarian arteries undergo changes. These arteries’ diameter increases or swells to accommodate the increased demands of the growing fetus and the developing placenta. This adaptation ensures that the uterus receives an adequate blood supply to support the pregnancy and the physiological changes that occur in preparation for childbirth.
In conclusion, the arteria ovarica or ovarian artery plays a crucial role in female reproduction. Its origin from the abdominal aorta, intricate connections, and strategic location within the reproductive system ensure that the ovary and uterus receive the necessary oxygen and nutrients for optimal functioning. From supplying blood to the ovary and uterus to establishing collateral circulation, the ovarian artery is a key component in maintaining reproductive health in women.
