Label the diagrams of the circulatory, respiratory, and urinogenital systems of the male and female guinea pig.

Here are the labels for the diagrams of the guinea pig's internal systems:

For the top diagram (Circulatory, respiratory and male urinogenital systems of guinea pig):

• Trachea: The windpipe, leading to the lungs.
• Lungs: The primary organs of respiration, located on either side of the heart.
• Heart: The central organ of the circulatory system, located between the lungs.
• Aorta/Vena Cava: Major blood vessels connected to the heart.
• Kidneys: Two bean-shaped organs located dorsally, responsible for filtering blood and producing urine.
• Ureters: Tubes connecting the kidneys to the urinary bladder.
• Urinary Bladder: A sac that stores urine.
• Testes: The male gonads, typically located in the scrotal sacs.
• Epididymis: Coiled tubes on the surface of the testes, where sperm mature and are stored.
• Vas Deferens: Tubes that carry sperm from the epididymis to the urethra.
• Penis/Urethra: The male copulatory organ and the tube for urine and semen exit.

For the bottom diagram (Circulatory, respiratory and female urinogenital systems of guinea pig):

• Trachea: The windpipe.
• Lungs: The respiratory organs.
• Heart: The central circulatory organ.
• Aorta/Vena Cava: Major blood vessels.
• Kidneys: The urine-producing organs.
• Ureters: Tubes connecting kidneys to the bladder.
• Urinary Bladder: The organ for urine storage.
• Ovaries: The female gonads, producing eggs and hormones.
• Oviducts (Fallopian tubes): Tubes connecting the ovaries to the uterus.
• Uterus: The organ where fetal development occurs, typically Y-shaped in guinea pigs.
• Vagina: The birth canal and copulatory organ.
