Septal nephridia are excretory structures found in certain invertebrates, particularly annelids like earthworms. They are located in the septa, which are the partitions separating body segments. These nephridia function to filter waste products from the coelomic fluid and help maintain osmotic balance by excreting nitrogenous wastes and excess salts. Each segment typically contains a pair of nephridia that open to the exterior, aiding in the organism's overall excretory system.
An earthworm's excretory system contains pairs of integumentary, septal, and pharyngeal nephridia. Each nephridia is located in a different segment of the body.
The excretory system of a worm is comprised of three pairs nephridia. Each type of nephridia, the integumentary, septal, and pharyngeal, is located in a different segment.

An earthworm's excretory system contains pairs of integumentary, septal, and pharyngeal nephridia. Each nephridia is located in a different segment of the body.
The excretory system contains a pair of nephridia in every segment, except for the first three and last one.There are three types of nephridia : integumentary, septal and pharyngeal nephridia. The integumentary nephridia lie attached to the inner side of the body wall in all segments except the first two. The septal nephridia are attached to both sides of the septa behind the 15th segment. The pharyngeal nephridia are attached to 4th, 5th and 6th segment. The nitrogenous wastes are removed by the rhythmic beating of the cilia of the nephridiostomes. The excretory wastes are then finally discharged into the gut.
In an earthworm, nephridia occur in all body segments except the first three segments. Integumentary nephridia are V-shaped and lack nephrostomes.
The water and nutrients are reabsorbed from the nephridia into the blood vessels surrounding the nephridia. This process helps to conserve essential substances and maintain the balance of fluids and solutes in the body.

nephridia
Nephridia are excretory organs found in many invertebrates, such as annelids and mollusks. They primarily consist of a tubular structure that filters waste from the coelomic fluid and excretes it. The main components of nephridia include the nephrostome (an opening for fluid intake), a tubule where reabsorption occurs, and an exterior opening for waste elimination. Overall, nephridia play a crucial role in osmoregulation and excretion.
The heart's septal wall is called the interatrial septum. The anatomical feature of the heart's septal wall is a crescent-shaped piece of tissue.
