In ovulation, after expelling the oocyte the follicle becomes ____________which produces_____________.

A. Ductus venosus and ductus arteriosus: The ductus venosus bypasses the liver, not the lungs. The ductus arteriosus does allow blood to bypass the lungs by connecting the pulmonary artery to the aorta. However, this option is not entirely correct since the ductus venosus is not involved in bypassing the lungs.

B. Foramen ovale and ductus arteriosus: The foramen ovale allows blood to pass directly from the right atrium to the left atrium, bypassing the lungs. The ductus arteriosus connects the pulmonary artery to the aorta, also bypassing the lungs.

C. Fossa ovalis and umbilical arteries and vein: The fossa ovalis is a remnant of the foramen ovale in adults and does not function in fetal circulation. The umbilical arteries and vein are involved in exchanging oxygenated and deoxygenated blood between the fetus and placenta, not bypassing the lungs.

D. Ligamentum venosum and ligamentum arteriosum: These are the adult remnants of the ductus venosus and ductus arteriosus, respectively. They do not play a role in fetal circulation.

A. Ingestion refers to the process of taking in food through the mouth, not the absorption of nutrients into the body's tissues.

B. Digestion involves the breakdown of food into smaller molecules that can be absorbed, but it does not refer to the actual uptake of these nutrients into tissues.

C. Absorption is the process of taking up nutrient molecules into the bloodstream from the digestive tract, which then allows them to be used by the body's tissues.

D. Compaction refers to the process of absorbing water and consolidating indigestible residues into feces, not the absorption of nutrients into tissues.
