4) B
Explanation:
A) In both humans and pigs, the trachea bifurcates into the left and right primary bronchi. Humans do not have an apical bronchus, which branches from the trachea anterior to the right primary bronchus in pigs.
C) In both humans and pigs, the trachea bifurcates into the left and right primary bronchi. Humans do not have an apical bronchus, which branches from the trachea anterior to the right primary bronchus in pigs.
D) In both humans and pigs, the trachea bifurcates into the left and right primary bronchi. Humans do not have an apical bronchus, which branches from the trachea anterior to the right primary bronchus in pigs.

A) The insula is a lobe found in the cerebral hemispheres.
C) The frontal lobe is found in the cerebral hemispheres.
D) The temporal lobes are found in the cerebral hemispheres.

6) A
Explanation:
B) The lungs of the pig have more lobes than the lungs of humans. The pig's right lung has four lobes: the apical bronchus supplies the apical lobe, and the right primary bronchus branches to supply the cardiac, intermediate, and diaphragmatic lobes.
C) The lungs of the pig have more lobes than the lungs of humans. The pig's right lung has four lobes: the apical bronchus supplies the apical lobe, and the right primary bronchus branches to supply the cardiac, intermediate, and diaphragmatic lobes.

C) The second ventricle is found in the cerebral hemisphere.
D) The fourth ventricle is found between the brain stem and the cerebellum.

8) D
Explanation:
A) Ganglia are groups of cell bodies.
B) Sulci are shallow grooves on the surface of the cerebral hemispheres.
C) Fissures are deep grooves on the cerebrum.

9) C
Explanation:
A) The central sulcus does not separate the temporal lobe from the parietal lobe.
B) The central sulcus does not separate the parietal from the occipital lobe.
D) The lateral sulcus separates the frontal from the temporal lobe.

10) A
Explanation:
B) The trachea divides (bifurcates) into left and right primary bronchi. The bronchi penetrate the lungs at a slit-like hilus and branch repeatedly to supply the alveoli with air.
C) The trachea divides (bifurcates) into left and right primary bronchi. The bronchi penetrate the lungs at a slit-like hilus and branch repeatedly to supply the alveoli with air.
D) The trachea divides (bifurcates) into left and right primary bronchi. The bronchi penetrate the lungs at a slit-like hilus and branch repeatedly to supply the alveoli with air.
