What is the function of the collecting tubule?

What is the function of the collecting tubule?

The last part of a long, twisting tube that collects urine from the nephrons (cellular structures in the kidney that filter blood and form urine) and moves it into the renal pelvis and ureters. Also called collecting duct.

What are the different collecting tubules?

proximal convoluted tubule (red: found in the renal cortex) loop of Henle (blue: mostly in the medulla) distal convoluted tubule (purple: found in the renal cortex) collecting tubule (black: in the medulla)

Which part of the renal tubule opens into the collecting tubule?

Many nephron distal convoluted tubules open into a straight tube called a collecting duct. Therefore DCT is a part of the nephron which opens up to collecting duct.

What are the collecting ducts of the kidneys?

The last part of a long, twisting tube that collects urine from the nephrons (cellular structures in the kidney that filter blood and form urine) and moves it into the renal pelvis and ureters. Also called renal collecting tubule.

What is the function of Bowman’s capsule?

Bowman’s capsule surrounds the glomerular capillary loops and participates in the filtration of blood from the glomerular capillaries. Bowman’s capsule also has a structural function and creates a urinary space through which filtrate can enter the nephron and pass to the proximal convoluted tubule.

What is the function of vasa recta?

Vasa Recta Function Not only do the vasa recta bring nutrients and oxygen to the medullary nephron segments but, more importantly, they also remove the water and solute that is continuously added to the medullary interstitium by these nephron segments.

Where do all collecting tubules lead?

The collecting tubules connect with the nephron tubules in the outer layer of the kidney known as the cortex.

What are the 4 parts of the renal tubules?

It contains four segments: the pars recta (the straight descending limb of proximal tubule), the thin descending limb, the thin ascending limb, and the thick ascending limb.

What is the function of glomerulus?

The glomerulus is responsible for blood filtration and is composed of a tuft of capillaries whose endothelial cells are interconnected with specialized renal visceral epithelial cells, called podocytes, and with mesangial cells.

Why is it called Bowman’s capsule?

Bowman’s capsule is named after Sir William Bowman (1816–1892), a British surgeon and anatomist. However, thorough microscopical anatomy of kidney including the nephronic capsule was first described by Ukrainian surgeon and anatomist from the Russian Empire, Prof.

What is the other name of vasa recta?

According to Terminologia Anatomica, the term “vasa recta renis” is an alternate name for “arteriolae rectae renis”, and a separate term, venulae rectae renis, is used to identify the venous portion.

Which one is not function of kidney?

Option D: Kidneys are not involved in secretion of antibiotics. Antibiotics are basically a range of medicines which are used to inhibit the growth and also kill microorganisms. Therefore, this is the incorrect option. Thus, the correct option is A) Regulation of blood pressure.

What are the functions of the male reproductive system?

Key Points The functions of the male reproductive system include producing and transporting sperm, ejaculating sperm into the female reproductive tract, and producing and secreting male hormones. Most of the male reproductive system is located outside of the body. The internal organs of the male reproductive system are called accessory organs.

Where does testosterone production occur in the male reproductive system?

The testis is the location for testosterone production. The coiled collection of tubes within the testes are the seminiferous tubules. Within these tubules, spermatogenesis takes place. The internal organs of the male reproductive system are called accessory organs.

Where does sperm travel in the male reproductive system?

Vas deferens — The vas deferens is a long, muscular tube that travels from the epididymis into the pelvic cavity, to just behind the bladder. The vas deferens transports mature sperm to the urethra in preparation for ejaculation.

Where is the epididymus located in the male reproductive system?

The epididymus is located at the back of the testis and connects it to the vas deferens. Its function is to store and carry sperm. The testis is the location for testosterone production. The coiled collection of tubes within the testes are the seminiferous tubules.
