The urinary bladder and the internal reproductive organs are found in which cavity?
Pleural cavity
Abdominal cavity
Pelvic cavity
Thoracic cavity
The Correct Answer is C
The urinary bladder and internal reproductive organs, including the uterus, ovaries, and testes, are in the pelvic cavity. The pelvic cavity is a bony structure formed by the pelvis and contains the terminal portions of the digestive tract, urinary tract, and reproductive tract. It is situated inferior to the abdominal cavity and is separated from it by the pelvic brim, which is a rim of bone formed by the iliac crests, sacrum, and pubic bones. The pelvic cavity is bounded by the pelvic bones and the pelvic diaphragm and is lined with the pelvic peritoneum.

Correct Answer is A
Explanation
Lysosomes contribute to phagocytosis in white blood cells by fusing with the phagosome, which is the membrane-bound vesicle that engulfs the foreign particle or pathogen during phagocytosis. The lysosomes contain hydrolytic enzymes that can break down the engulfed material, thereby helping to destroy the invading pathogen. Additionally, lysosomes can also release reactive oxygen species and other antimicrobial molecules that further aid in the destruction of the pathogen.
Vacuoles, endoplasmic reticulum, and Golgi apparatus do not directly contribute to phagocytosis in white blood cells. Vacuoles are used for storage in cells, while the endoplasmic reticulum and Golgi apparatus are involved in protein synthesis and processing.
Correct Answer is A
Explanation
Also known as platelets, are cell fragments in the blood that play a crucial role in blood clotting or coagulation. When a blood vessel is injured, thrombocytes are activated and clump together to form a platelet plug that stops the bleeding. They also release substances that promote blood clotting and help to repair the damaged blood vessel. Therefore, the function of thrombocytes is important in preventing excessive bleeding and promoting wound healing. Options a, c, and d are incorrect because they do not describe the function of thrombocytes.
