Question

match the correct body cavity with the letter in the diagram.
column a

1. lower abdominal/pelvic cavity
2. dorsal cavity
3. ventral cavity
4. spinal cavity
5. thoracic cavity
6. upper abdominal cavity

column b
a. b in the diagram
b. f in the diagram
c. c in the diagram
d. e in the diagram
e. d in the diagram
f. h in the diagram

Explanation:

1. Lower Abdominal/Pelvic Cavity: The pelvic cavity (H in the diagram) is the lower abdominal/pelvic region. So match with f.
2. Dorsal Cavity: The dorsal cavity includes the cranial (A) and spinal (D, C) cavities. The option for dorsal cavity is c (C in the diagram? Wait, no, dorsal cavity is A (cranial) + C (spinal? Wait, the dorsal cavity has cranial (A) and spinal (C and D? Wait, the diagram: A is cranial, C and D are spinal? Wait, the dorsal cavity is made of cranial (A) and spinal (C - maybe the spinal cavity? Wait, the options: for dorsal cavity, the option is c? Wait, no, let's recheck. The dorsal cavity includes cranial (A) and spinal (C, D? Maybe the dorsal cavity is represented by the combination of A, C, D? But the options: column B has c: C in the diagram, e: D in the diagram. Wait, maybe the dorsal cavity is the one with A, C, D, but the option for dorsal cavity is c? Wait, no, let's think again. The dorsal cavity (back side) has cranial (A) and spinal (C - spinal cavity? Or D? Wait, the spinal cavity is along the spine, so C or D? Maybe the dorsal cavity is the set of A, C, D, but the option for dorsal cavity is c (C in the diagram) or e (D)? Wait, maybe I made a mistake. Let's check each:

1. Lower Abdominal/Pelvic Cavity: This is H (f in column B: H in the diagram). So 1 - f.

1. Dorsal Cavity: The dorsal cavity includes cranial (A) and spinal (C, D). The option for dorsal cavity is c (C in the diagram) or e (D)? Wait, maybe the dorsal cavity is represented by the combination, but the option is c? Wait, no, let's check standard body cavities. Dorsal cavity: cranial (A) and spinal (C - spinal cavity). So the dorsal cavity would be the one with A, C, D? But the options: column B has c: C in the diagram. So 2 - c? Wait, no, maybe the dorsal cavity is the one labeled C? Wait, maybe the diagram: A is cranial, C is spinal cavity, D is also spinal? No, maybe C is the spinal cavity, D is another? Wait, maybe I should recall: dorsal cavity (posterior) has cranial (A) and spinal (C). So the dorsal cavity is A + C + D? No, maybe the dorsal cavity is the one with A, C, D, but the option for dorsal cavity is c (C in the diagram). So 2 - c.

1. Ventral Cavity: The ventral cavity (anterior) includes thoracic (B) and abdominopelvic (G, which is E and H). So the ventral cavity is B + E + H + G? The option for ventral cavity is b (F in the diagram? Wait, F is connected to G. Wait, column B: b is F in the diagram. So ventral cavity is F? Wait, maybe F is the ventral cavity. So 3 - b.

1. Spinal Cavity: The spinal cavity is along the spine, so D in the diagram (e in column B: D in the diagram). So 4 - e.

1. Thoracic Cavity: The thoracic cavity is B in the diagram (a in column B: B in the diagram). So 5 - a.

1. Upper Abdominal Cavity: The upper abdominal cavity is E in the diagram (d in column B: E in the diagram). So 6 - d.

Let's verify:

1. Lower Abdominal/Pelvic Cavity: H (f) - correct.

1. Dorsal Cavity: C (c) - correct (dorsal includes cranial and spinal; C is spinal part).

1. Ventral Cavity: F (b) - ventral is anterior, F is the ventral cavity.

1. Spinal Cavity: D (e) - spinal cavity is D.

1. Thoracic Cavity: B (a) - thoracic is B.

1. Upper Abdominal Cavity: E (d) - upper abdominal is E.

Answer:

1. f. H in the diagram
2. c. C in the diagram
3. b. F in the diagram
4. e. D in the diagram
5. a. B in the diagram
6. d. E in the diagram
