Gross Anatomy of the Liver01:17

Gross Anatomy of the Liver

2.5K
The liver, the largest gland within the human body, is a firm and reddish-brown organ. This wedge-shaped structure weighs approximately 1.5 kg and occupies a significant portion of the right hypochondriac and epigastric regions. It extends more to the right of the body's midline than to the left.
Located under the diaphragm, the liver is almost entirely ensconced within the rib cage, providing it with substantial protection. Except for the superior most bare area, the liver's surface is...

Abdominal Regions and Quadrants01:19

Abdominal Regions and Quadrants

19.3K
To promote clear communication, for instance, about the location of a patient's abdominal pain or a suspicious mass, anatomists and clinicians typically use imaginary lines to categorize the abdominopelvic cavity into either four quadrants or nine regions to identify organs in the cavity.
The simpler quadrants approach, which is more commonly used in medicine, subdivides the cavity with one horizontal and one vertical line that intersects at the patient's umbilicus (navel). The four...

Gross Anatomy of the Lungs01:17

Gross Anatomy of the Lungs

6.0K
The lungs are a pair of vital organs connected to the trachea via the left and right bronchi. The base of these organs meets the dome-shaped muscle known as the diaphragm. Encased by the pleurae, the lungs contact the mediastinum. The right lung is shorter yet wider, and has a larger volume than the left lung. The left lung has an indentation known as the cardiac notch. The superior region of the lungs is referred to as the apex, whereas the base is the lower region near the diaphragm. The...

Gallbladder01:17

Gallbladder

2.8K
The gallbladder is a small, pear-shaped organ that plays a crucial role in our digestive system. Measuring about 10 cm in length, it is comparable in size to a kiwi fruit and is located in a hollow area on the lower surface of the liver. The gallbladder's primary function is to store and concentrate bile, a fluid produced by the liver that aids in digestion.
The gallbladder's anatomy consists of three regions: the fundus, body, and neck. Extending from the neck, the cystic duct joins...

Major Organs of the Digestive System

11.8K
The digestive system is responsible for the ingestion of food, secretion of enzymes, mixing and digesting food, absorption of the nutrients and defecation. The human digestive system consists of two major parts: the gastrointestinal tract and the accessory digestive organs.

Anatomy of Respiratory System II: Lower Respiratory Tract01:31

Anatomy of Respiratory System II: Lower Respiratory Tract

5.0K
The lower respiratory tract is anatomically composed of several vital structures, including the larynx, trachea, bronchial tree, alveoli, lungs, and pleurae. Each component has a specific function, and all are intricately connected to ensure efficient respiration.
The Larynx
It is located between the pharynx and the trachea, acts as a passageway for air, and hosts several critical structures, such as the epiglottis, vocal cords, and glottis. The epiglottis acts as a gateway, guiding food to the...

Supradiaphragmatic right liver lobe and gallbladder

    Summary

    A rare congenital anomaly presented a right liver lobe and gallbladder abnormally positioned above the diaphragm. This unique case highlights congenital diaphragmatic positioning without prior trauma.

    Area of Science:

    • Anatomy
    • Congenital Anomalies
    • Surgical Pathology

    Background:

    • Supradiaphragmatic liver lobules are occasionally noted in literature, primarily associated with diaphragmatic hernia.
    • Understanding congenital positional anomalies of abdominal organs is crucial for accurate diagnosis.

    Observation:

    • A unique case involving a congenitally positioned right liver lobe and gallbladder in the supradiaphragmatic space was identified.
    • The patient exhibited no history of trauma or known diaphragmatic hernia.

    Findings:

    • The right liver lobe and gallbladder were found in an abnormal supradiaphragmatic location.
    • The surrounding anatomy, apart from the liver and gallbladder position, was otherwise normal.

    Implications:
