1. the pectoralis minor muscles and the sternocleidomastoid muscles are used in forced expiration.

true
false

1. the glottis is the opening between the vocal cords.

true
false

1. at rest, the kidneys receive about a quarter of the blood coming from the heart.

true
false

1. the organs of the upper respiratory tract are located outside the thorax.

true
false

Explanation:

• 44: The correct sequence of renal tubule segments for filtrate flow is proximal tubule, descending limb of nephron loop, ascending limb of nephron loop, distal tubule.
• 45: The renal corpuscle consists of the glomerulus and the glomerular capsule.
• 46: Carbon dioxide affects the pH of blood through the bicarbonate buffer system.
• 47: The pectoralis minor and sternocleidomastoid muscles are not used in forced expiration; muscles like the internal intercostals and abdominal muscles are.
• 48: The glottis is indeed the opening between the vocal cords.
• 49: At rest, the kidneys receive about a quarter of the cardiac output.
• 50: The organs of the upper respiratory tract (e.g., nose, pharynx) are located outside the thorax.

Answer:

• 44) B. Proximal tubule, descending limb of nephron loop, ascending limb of nephron loop, distal tubule
• 45) A. Glomerulus and glomerular capsule
• 46) C. Carbon dioxide
• 47) false
• 48) true
• 49) true
• 50) true
