23 sty 2023 · This article explored the structure and function of the kidneys and discussed the role of this organ in human physiology. The nephrons are central to the function of the kidneys and are crucial to the production of urine, electrolyte balance and blood volume.
3 lis 2023 · The main function of the kidney is to eliminate excess bodily fluid, salts and byproducts of metabolism – this makes kidneys key in the regulation of acid-base balance, blood pressure, and many other homeostatic parameters.
11 lis 2021 · The main function of the jejunum is absorption of important nutrients such as sugars, fatty acids, and amino acids. Peristalsis, the involuntary contraction of smooth muscles that moves...
There are at least 16 different highly specialized epithelial cell types in the mammalian kidney. The number of specialized endothelial cells, immune cells, and interstitial cell types might even be larger. The concerted interplay between different cell types is critical for kidney function.
27 paź 2020 · A nephron has three functions: glomerular filtration (of water and solutes within the blood), tubular reabsorption (the return of water and required molecules to the circulation), and tubular secretion (of waste or excess molecules – including water) into a distal tube. This secreted fluid is known as urine.
Innervation of the jejunum includes the enteric nervous system (sensory and motor), the autonomic nervous system (sympathetic and parasympathetic), and extrinsic sensory innervation (visceral afferents) (Standring, 2016). The vagus nerve (CN X) provides parasympathetic innervation to the jejunum.
