Lab 10: Respiratory and Urinary Flashcards
Name & Characteristics
Kidney
Characteristics: Glomeruli surrounded by Bowman’s capsules; aforementioned structures separated by capsular space; glomeruli demark the division between cortex and medulla in kidney
Name & Function
- *Kidney**
- *Function:** Filtration of blood; absorption and secretion of water, urea, and ions
Name & Location
- *Kidney**
- *Location:** Retroperitoneal region
Name & Characteristics
Bronchiole
Characteristics: Cross-section with pseudostratified epithelium surrounded by hyaline cartilage, smooth muscle and adventitia. Hyaline cartilage and smooth muscle are also found in the bronchioles.
Name & Function
Bronchiole
Function: Passage of airway in the respiratory tract that conducts air into the lungs.
Name & Location
Bronchiole
Location: Lungs
Name & Characteristics
Urethra
Characteristics: The epithelium of the urethra starts off as transitional cells as it exits, further along the urethra there are stratified columnar cells, then stratified squamous cells near the external urethral orifice.
There are small mucus-secreting urethral glands, that help protect the epithelium from the corrosive urine.
Name & Function
Urethra
Function: Tube that connects the urinary bladder to the genitals. In males, the urethra travels through the penis, and carries semen as well as urine. In females, the urethra is shorter and emerges above the vaginal opening.
Name & Location
Urethra
Location: The external urethral sphincter is a striated muscle that allows voluntary control over urination. Urethra is found as an extension to the urinary bladder.
Name & Characteristics
Renal Tubules
Characteristics: Contain simple cuboidal epithelium
Name & Function
Renal Tubules
Function: The renal tubule is the portion of the nephron containing the tubular fluid filtered through the glomerulus. After passing through the renal tubule, the filtrate continues to the collecting duct and exists the kidney.
Name & Location
Renal Tubules
Location: Kidney
