Correct Answer: B

Rationale: The correct answer is B: Fibrous joint. Fibrous joints are immovable joints that connect bones with dense fibrous connective tissue. In the skull, the bones are joined by fibrous sutures, which provide stability and protect the brain. Hinge joints (A) allow movement in one direction, not present in the skull. Ball-and-socket joints (C) allow for a wide range of motion, not fitting the immovable nature of skull joints. Pivot joints (D) allow rotation, which is not a characteristic of skull joints. Therefore, the fibrous joint is the correct type of joint that connects the bones of the skull.

Correct Answer: B

Rationale: The correct answer is B: To filter blood and produce urine. The kidneys play a crucial role in filtering waste products and excess substances from the blood to form urine, which helps maintain the body's balance of fluids and electrolytes. This process is essential for regulating blood pressure, producing hormones, and maintaining overall bodily function. Choices A, C, and D are incorrect because the kidneys are not involved in digesting food, absorbing nutrients, or transporting oxygen.

Correct Answer: B

Rationale: The correct answer is B: Ligaments. Ligaments are fibrous connective tissues that connect bones to other bones, providing stability and support to joints. Tendons (A) connect muscles to bones, not bones to other bones. Cartilage (C) is a type of connective tissue that cushions joints but does not directly connect bones. Muscle (D) is responsible for movement and does not directly connect bones to other bones. Therefore, the correct choice is ligaments as they specifically serve the function of connecting bones to other bones.

Correct Answer: A

Rationale: The correct answer is A: Abdominal. The peritoneum primarily lines the abdominal cavity, providing a protective and lubricating membrane for the abdominal organs. The peritoneum does not line the dorsal (B), ventral (C), or thoracic (D) cavities. The dorsal cavity is lined by the meninges, the ventral cavity is lined by serous membranes, and the thoracic cavity is lined by the pleura. Therefore, the peritoneum specifically lines the abdominal cavity, making choice A the correct answer.

Correct Answer: B

Rationale: The correct answer is B: Lipids. Lacteals are lymphatic vessels located in the small intestine that absorb dietary fats (lipids) and fat-soluble vitamins. They play a crucial role in the absorption and transport of lipids into the bloodstream. Carbohydrates are primarily absorbed in the form of glucose through the villi, not the lacteals. Proteins are broken down into amino acids and absorbed through the villi as well. Nonpolar nutrients, while including lipids, are a broad category that may not specifically refer to lipids being absorbed by lacteals.
