This exercise fosters a comprehensive understanding of the respiratory system’s essential role in oxygen uptake and carbon dioxide removal.
Urinary System
The urinary system dissection exercise provides a detailed exploration of the cat’s organs responsible for waste filtration and excretion. Students will carefully dissect and examine the kidneys, ureters, urinary bladder, and urethra, identifying their distinct structures and functions. The manual guides them through the intricate network of nephrons within the kidneys, highlighting the processes of filtration, reabsorption, and secretion that maintain fluid and electrolyte balance. Students will learn about the structure of the ureters, which transport urine from the kidneys to the bladder, and the bladder’s role in storing and expelling urine. The dissection will reveal the muscular nature of the bladder wall, enabling its expansion and contraction, and the urethral sphincters that control urine flow.
