Which of the following functions is associated with skeletal muscle?
Forming the contractile component of the digestive urinary, and reproductive systems
Contracting to cause involuntary muscle movements
Pumping blood throughout the body
Shivering for heat production
The Correct Answer is D
a. Forming the contractile component of the digestive, urinary, and reproductive systems: This describes smooth muscle, not skeletal muscle.
b. Contracting to cause involuntary muscle movements: This is a characteristic of smooth and cardiac muscles. Skeletal muscle is primarily involved in voluntary movements.
c. Pumping blood throughout the body: This is the function of cardiac muscle, not skeletal muscle.
d. Shivering for heat production: Correct. Skeletal muscles generate heat through shivering, which is an involuntary contraction response to cold.

Correct Answer is D
Explanation
a. Prothrombin: This is a protein involved in blood clotting, not in maintaining colloid osmotic pressure.
b. Globulins: These are involved in immune responses and transportation of substances but are not the primary proteins for colloid osmotic pressure.
c. Fibrinogen: This is a clotting factor that helps in blood coagulation, not in colloid osmotic pressure.
d. Albumin: Albumin is the main plasma protein responsible for maintaining colloid osmotic pressure, which helps to keep fluid within the blood vessels.
Correct Answer is C
Explanation
a. Intercostal muscles: Intercostal muscles are located between the ribs and help with breathing movements. They don't separate the pleurae.
b. Pleural cavity: The pleural cavity is the space between the pleura and the lung on each side. There isn't another pleural cavity within this space.
c. Mediastinum: The pleura are two thin membranes that line the lungs and inner chest wall. The mediastinum is the central compartment of the thoracic cavity, containing essential structures like the heart, trachea, esophagus, and major blood vessels. It separates the right and left pleural cavities.
d. Diaphragm: The diaphragm is a dome-shaped muscle separating the thoracic cavity from the abdominal cavity. While it plays a role in respiration, it doesn't directly separate the pleurae
