All the following are functions of the digestive system except:
Break down ingested foods
Digest ingested foods to release nutrients
Production of red blood cells
Excretion of waste products
The Correct Answer is C
A. Break down ingested foods: The digestive system performs mechanical and chemical breakdown (e.g., chewing, enzymes) of ingested food.
B. Digest ingested foods to release nutrients: Digestion (chemical breakdown) releases absorbable nutrients (amino acids, monosaccharides, fatty acids).
C. Production of red blood cells: Hematopoiesis (production of RBCs) occurs mainly in bone marrow (and in fetal life the liver/spleen), not as a function of the digestive tract.
D. Excretion of waste products: The digestive system eliminates undigested material and some metabolic wastes as feces.

Correct Answer is B
Explanation
A. Spermatogenesis and oogenesis both contribute to the maturation of the embryo:gametogenesis produces gametes for fertilization; embryonic maturation occurs after fertilization.
B. Spermatogenesis produces mature sperm for fertilization, while oogenesis generates mature ova for fertilization: spermatogenesis and oogenesis are the gamete-producing processes that supply sperm and ova needed for sexual reproduction.
C. Spermatogenesis is responsible for the development of the uterine lining, while oogenesis produces hormones to regulate the menstrual cycle:uterine lining development is driven by ovarian hormones (estrogen/progesterone); gametogenesis itself does not directly build the endometrium.
D. Spermatogenesis and oogenesis are sex hormones necessary for reproductive health: spermatogenesis and oogenesis are cellular processes (gamete production), not hormones.
