| Question | Answer |
|---|---|
| What is the main function of glucose metabolism? | To convert glucose into ATP for cellular energy. |
| What are the end products of carbohydrate digestion? | Monosaccharides—primarily glucose, fructose, and galactose. |
| Name the correct food pathway through the GI tract. | Mouth → Pharynx → Esophagus → Stomach → Small Intestine → Large Intestine → Rectum → Anus. |
| What is the purpose of peristalsis? | To move food through the digestive tract via rhythmic muscle contractions. |
| What is the role of digestive enzymes? | To chemically break down food into absorbable molecules. |
| How do kidney tubules help regulate blood pH? | By excreting hydrogen ions and reabsorbing bicarbonate. |
| What is the function of cholecystokinin (CCK)? | It stimulates bile release from the gallbladder and enzyme secretion from the pancreas. |
| What is the difference between asexual and sexual reproduction? | Asexual reproduction produces identical offspring; sexual reproduction involves gametes and increases genetic variation. |
| What do male reproductive glands secrete? | Seminal fluid containing fructose, enzymes, and alkaline substances. |
| What are the essential organs of reproduction? | Gonads — testes in males, ovaries in females. |
| Which hormones are secreted during breastfeeding? | Prolactin (milk production) and oxytocin (milk let-down). |
| Name common male fertility factors. | Low sperm count, impaired motility, or abnormal morphology. |
| Match the hormone with its function: Oxytocin. | Stimulates labor contractions and milk ejection. |
| Match the hormone with its function: Calcitonin. | Lowers blood calcium levels. |
| Match the hormone with its function: Glucagon. | Raises blood glucose levels by stimulating glycogen breakdown. |
| What occurs during the proliferative phase of the menstrual cycle? | The endometrium thickens as estrogen levels rise to prepare for possible implantation. |
