Final answer:
The urinary system filters blood, excretes waste, and maintains electrolyte and water balance. The reproductive system is responsible for gamete production and conception in females. Mucous membranes line various tracts and are coated with mucous glands.
Step-by-step explanation:
The urinary system filters blood, excretes waste, and maintains an appropriate electrolyte and water balance. The reproductive system is responsible for the production of gametes and participates in conception and, in females, the development of offspring. Due to their proximity and overlap, these systems are often studied together and referred to as the urogenital system (or genitourinary system).
Mucous membranes line the digestive, respiratory, urinary, and reproductive tracts. They are coated with the secretions of mucous glands. A closed circulatory system (like cephalopods). An excretory system consisting of tubular nephridia. A complete digestive system. A brain.
