By the end of 8 weeks, the individual is considered a fetus because___________
A. the neural tube and yolk sac have formed
The neural tube and yolk sac have formed: By 8 weeks, the neural tube and yolk sac have formed, but this is not the criterion for defining a fetus.
B. the amniotic cavity has formed
The amniotic cavity has formed: The formation of the amniotic cavity occurs earlier in development and is not the defining feature of a fetus.
C. all of the organ systems are present
All of the organ systems are present: By the end of 8 weeks, the basic structures of all major organ systems are present, which is why the embryo is referred to as a fetus from this point onwards.
D. the mesoderm has formed
The mesoderm has formed: The formation of the mesoderm occurs earlier and is not the defining factor for fetal status. By 8 weeks, more significant development, including the presence of organ systems, has occurred.

Blood plasma is filtered in the____________.
A. renal corpuscle
Renal corpuscle: Blood plasma is filtered in the renal corpuscle, which includes the glomerulus and Bowman's capsule.

Which of the following nutrients is absorbed by the lacteals of the small intestine?
A. Minerals
Minerals are absorbed directly into the bloodstream, not through lacteals.
B. Glucose
Glucose is absorbed directly into the bloodstream through capillaries, not through lacteals.
C. Amino acids
Amino acids are absorbed into the bloodstream through capillaries, not through lacteals.
D. Triglycerides
Triglycerides are absorbed by the lacteals in the small intestine. Lacteals are lymphatic vessels that transport absorbed lipids (including triglycerides) from the digestive tract.
