1. Introduction Uterus is a hollow, muscular, pear-shaped organ in the female pelvis. Also called the womb. Primary function: Nourishment and development of the fetus during pregnancy. 2. Location In female pelvis, between the urinary bladder (anteriorly) and the rectum […]
Fallopian Tube (Uterine Tube) – Anatomy Notes 1. Introduction Also called: Uterine tube or Oviduct. Function: Transport ova from the ovary to the uterus. Site of fertilization (usually in the ampulla). 2. Parts of the Fallopian Tube (from lateral → […]
1. Main Functions Production of female gametes (ova): Occurs in the ovaries via oogenesis. Reception of male gametes (sperm): Happens through the vagina during sexual intercourse. Fertilization: Usually occurs in the fallopian tubes. Implantation and development of embryo: Takes place […]
Overview of the Distal Convoluted Tubule (DCT) Location: Part of the nephron in the kidney, located between the loop of Henle and the collecting duct. Function: Fine-tunes the composition of urine by selective reabsorption and secretion of ions, water, and […]
Overview of the Loop of Henle: The Loop of Henle is part of the nephron in the kidney and plays a major role in concentrating urine. It consists of: Segment Description Permeability Descending Limb Goes deep into the medulla Permeable […]
Notes on Proximal Convoluted Tubule (PCT) – Reabsorption & Secretion Overview of the PCT Location: First segment of the nephron tubule, following Bowman’s capsule. Structure: Composed of simple cuboidal epithelium with extensive microvilli (brush border) to maximize surface area for […]
Structure of Glomerulus The glomerulus is a network of capillaries located at the beginning of a nephron in the kidney. It is enclosed within a Bowman’s capsule and plays a crucial role in the process of urine formation. Key structural […]
The plasma membrane, a flexible yet sturdy barrier that surrounds and contains the cytoplasm of a cell, is best described by using a structural model called the fluid mosaic model. According to this model, the molecular arrangement of the plasma […]
Normally, the osmotic pressure of the cytosol is the same as the osmotic pressure of the interstitial fluid outside cells. Because the osmotic pressure on both sides of the plasma membrane (which is selectively permeable) is the same, cell volume […]
