Fetal Pig Dissection: Urinary System

Adrenal glands

part of endocrine system, responsible for producing hormones that regulate bodily functions such as metabolism, immune response, blood pressure, stress response, and sexual characteristics development.

Kidneys

bean-shaped organs responsible for filtering blood, removing waste, and maintaining bodily fluid balance

Kidney cortex

The kidney's outer layer, containing nephrons and erythropoietin, filters blood and regulates fluid balance, blood pressure, and electrolyte levels.

Kidney medulla

filters liquid waste, retains fluid in case the body is dehydrated, balances electrolytes, and eliminates extra acidity in the bloodstream

Renal pyramids

helps with blood filtration and water concentration regulation within your kidneys, helps collect and transport urine

Renal columns

provide structural support and divides the kidney into lobes, assisting in the pathway of blood vessels and tubules, facilitates the collection of urine from the nephron

Calyces

small, cup-shaped kidney chambers, collect urine from renal papillae tips and are classified as minor or major calyces.

Renal papilla

located at the apex of renal pyramids, drains urine from nephrons into the minor calyx through papillary ducts.

Renal pelvis

a funnel-shaped kidney cavity, collects and directs urine from the nephrons, directing it into the ureter and storing it in the bladder.

Ureters

muscular tubes that transport urine from the kidneys to the bladder, essential for eliminating waste products from the body

Urinary bladder

a muscular organ, stores urine from the kidneys and regulates waste removal and fluid balance during urination.

Urethra

a muscular tube that carries urine from the bladder to the outside of the body during urination

Nephron

filters blood, re absorbs substances, and excretes waste, maintaining fluid and electrolyte balance in the body.
