Hindgut

Hindgut is the posterior part of the embryonic intestine, from which part of the large intestine, rectum, bladder and urinary ducts subsequently develop.

The hindgut is formed in the early stages of embryonic development from the posterior intestinal tube. It is a continuation of the midgut (Midgut) and passes into the cloaca - a common cavity into which the urinary and reproductive ducts open.

As the embryo develops, the hindgut differentiates into separate organs. From its anterior part the descending part of the colon, the sigmoid colon and the rectum are formed. From the distal part the bladder and ureters are formed.

Thus, the Hindgut gives rise to important structures of the digestive and urinary systems. Its proper development is critical for normal human embryogenesis.

The hindgut is the posterior part of the intestine that develops from the primary intestine in the embryo. This part of the intestine is an important organ in the development of the body, as it participates in the formation of many organs and systems.

The hindgut develops from the posterior part of the primary intestine and begins to form in the 3rd week of embryonic development. It consists of two main sections: the proximal colon and the distal colon. The proximal portion forms most of the rectum, and the distal portion forms the bladder, urinary canals, and most of the colon.

The hindgut is where important processes related to digestion, nutrient absorption, and waste elimination occur. Here the breakdown of proteins, fats and carbohydrates occurs, as well as the absorption of nutrients into the blood. Waste products, such as undigested food, are eliminated from the body through the rectum.

In addition, the hindgut plays an important role in the development of the urinary system. The urinary ducts, which develop at the base of the hindgut, are responsible for removing urine from the body.

Thus, the hindgut is an important organ that is involved in the development of many organs and systems of the body. Its proper formation and functioning are key factors for normal human development and health.

Intestine posterior - the back part of the abdominal cavity, from where in embryonic development some parts of the colon, rectum, bladder, as well as the kidneys and urinary ducts will develop. This area is also called the “cloaca”.

The development of the large intestine occurs without any changes in the yolk sac in the rabbit's body, which is reflected in the formation of the embryonic sac and, accordingly, the rectum after the eighth week of development. The process slows down in the last seven weeks before stopping completely by the eighth week (fetal period). If the intestine continues to grow, then the rectum can be distinguished by the shape of the testicle of the cloacal sac. It continues to contract and swallow until the yolk sac has healed at 26-33 days of pregnancy.
