Internally, the kidney has three regions—an outer cortex, a medulla in the middle, and the renal pelvis in the region called the hilum of the kidney. The hilum is the concave part of the bean-shape where blood vessels and nerves enter and exit the kidney; it is also the point of exit for the ureters.

Q. Which structure is the first to collect urine?
Answer and Explanation: Metabolic waste is considered urine first in the collecting duct of the nephron. From the collecting duct, the urine will travel to the minor and major calyces and then the renal pelvis before leaving the kidney via the ureter.
Q. What are the two types of nephrons and the difference between them?
Cortical nephron is a microscopic structural and functional unit of the kidney with a short loop of Henle. Juxtamedullary nephron is a microscopic structural and functional unit of the kidney with a long loop of Henle. Cortical nephrons have a short loop of Henle, which penetrates only the outer renal medulla.
Q. What are the hormones that regulate urine output?
Antidiuretic Hormone (ADH) The hypothalamus produces a polypeptide hormone known as antidiuretic hormone (ADH), which is transported to and released from the posterior pituitary gland. The principal action of ADH is to regulate the amount of water excreted by the kidneys.
Q. Which hormone increases reabsorption of water in the kidneys?
Vasopressin (antidiuretic hormone) acting at V2 receptors enhances water reabsorption by increasing aquaporin-2 channels in the renal collecting duct.
Q. What are the three hormones that regulate urine volume?
There are three hormones that play key roles in regulating fluid and electrolyte balance: 1) antidiuretic hormone, released from the posterior pituitary; 2) aldosterone, secreted from the adrenal cortex; and 3) atrial natriuretic peptide, produced by the heart. We will consider the role of each in turn.
Q. What stimulates urine production?
Antidiuretic hormone stimulates water reabsorbtion by stimulating insertion of “water channels” or aquaporins into the membranes of kidney tubules. These channels transport solute-free water through tubular cells and back into blood, leading to a decrease in plasma osmolarity and an increase osmolarity of urine.
Q. What is the most important trigger for aldosterone release?
renin-angiotensin mechanism
Q. Which group of hormones cause an anti inflammatory action?
Which group of hormones cause an anti-inflammatory action? hypothyroidism.
Q. What hormones cause pain and inflammation?
Prostaglandins act as signals to control several different processes depending on the part of the body in which they are made. Prostaglandins are made at sites of tissue damage or infection, where they cause inflammation, pain and fever as part of the healing process.
