Structure of the Urinary System A&P TEAS Flashcards
What is the structure of the Urinary System?
- Kidneys
- Renal Cortex
- Renal Medulla
- Ureters
- Bladder
- Urethra
- Kidneys
- The Kidneys are a pair of organ that filter blood and produce urine.
- Renal Cortex
- The Renal Cortex is the outer layer of the kidney that contains the renal pyramids and blood vessels. Erythropoietin is stimulated in the production of new blood cells.
- Renal Medulla
- The Renal Medulla is the inner layer of the kidney that help to concentrate urine.
- Ureters
- The Ureters are a pair of tubes that carry urine from the kidneys to the bladder.
- Bladder
- The Bladder is a sac that stores urine until it is ready to be excreted.
- Urethra
- The Urethra is a tube that carries urine from the bladder to the outside of the body.
What are the functions of the urinary system?
The urinary system is an integral part of the homeostasis within the body. The system helps excrete waste and maintain balance.
What Is the structural unit of the Kidney?
The Nephron. Nephrons are responsible for the filtration of blood by removing waste and reabsorbing water and molecules.
What are the Nephrons composed of?
The Glomerulus and Renal tube.
What is the Glomerulus?
The Glomerulus is a ball of capillaries that is the site of filtration in the neuron
What is the Renal Tubule?
The Tubule is a tube that leads from the Glomerulus into the renal pelvis. The tubule is responsible for reabsorption and secretion. The remains from the tubule will be carried into the kidney and drained out from the ureter.
