The fetal heart rate is about double that of a healthy adult.

All the blood present in the umbilical vein enter the left ventricle.

Two of the embryo shunts close just after the parturition.

Fetal blood pressure is higher than that of an adult.

The peripheral chemoreceptors are well functional in the developing embryo and in a newborn.

In the newborn, complete output of the right ventricle is sent to the lungs.

Deficiency of surfactant in the newborn has no effect on respiration.

The first breath in a newborn is associated with numerous modulation in the intrathoracic pressure.

Fetal corticoids stimulate the production of pulmonary surfactant by alveolar type II cells.

The fetal zone of the adrenal gland produces huge amount of testosterone.

The regulation of acid-base balance of the fetus is govern by the kidneys.

The fetal kidneys starts producing a hypertonic urine after about 6 to 8 weeks of gestation.

The sex of the developing embryo is determined by a single gene present on the Y chromosome.

In the absence of a Y chromosome, the sexual development of the developing embryo will fail to follow any pattern.

The maturation of the fetal gonads into the female type are initiated in the presence of estrogens.

The sex of the developing embryo is determined by the set of genes on the Y chromosome.

In a developing embryo, the blood bouncing back to the umbilical vein is completely saturated with O₂.

Fetal hemoglobin has a higher compatibility for oxygen than adult hemoglobin.

In a normal foetus, the blood has a lower hemoglobin content than adult blood.

Blood reaching the brain of a fetus has the same PO₂ as that of blood in the descending aorta.

Erection in males is a sympathetic reflex.

During ejaculation, the sperms are mixed with secretions from the prostate and seminal vesicles.

In females, the fertilization occurs in the uterus.

Fertilization may occur two or more days after ovulation.

The placenta nourishes the developing embryo by implementing a dialysis pattern for exchange between the maternal and fetal circulations.

The placental barrier is highly permeable to glucose and amino acids.

The PO₂ of the blood of the umbilical vein in the developing embryo is the same as that in the maternal arterial blood.

The estrogens secreted by the placenta during pregnancy decelerates.

In a pregnant lady, the plasma hCG levels are the highest between weeks 8 and 10 of gestation.

Placental progesterone secretion is the highest in the first 10 to 12 weeks of gestation.

Blood flow to the kidneys decreases to maintain the pregnancy.

Maternal respiratory rate increases for supplying oxygen to the developing embryo.

In a nursing mother, the prolactin stimulates milk ejection .

Placental steroid secretion decelarates lactation during pregnancy.

In a nursing mother, the vasopressin is secreted in response to suckling.

In a nursing mother, the oxytocin secretion can be suppressed by dopamine agonists.

A mature human sperm contains a complete set of chromosomes.

Primary spermatocytes divide by mitosis to give rise to spermatids.

At parturition, an ovary contains all the oocytes it will ever have.

The sperm is known as male zygotes.

The myometrium propagates under the strict control of FSH.

The estrogens are produced predominantly by the cells of the theca interna.

After ovulation, the ruptured follicle gets transformed into a corpus albicans that secretes progesterone.

Progesterone promotes full development of the endometrium.

The segmentation movements propel down the bolus .

The pH of saliva in the buccal cavity accelerates as its rate of secretion increases.

Hormones play more significant role than nerves in the governing of salivary secretion.

Swallowing in humans is a totally voluntary activity.

The beggining phase of the menstrual cycle is known as the luteal phase.

The initiation of the preantral phase of follicular development is under the control of two hormones named as LH and FSH.

The advancement of the antral follicle is predicated on the expression of receptors for FSH and LH.

Ovulation occurs to reciprocate a sudden increase in plasma FSH.

Parietal cells of the gastric glands secrete gastric acid in response to hormonal stimulation.

In an individual, most of the acid and pepsinogen released by the stomach takes place during the intestinal phase of gastric secretion.

Gastric secretion does not commence unless the bolus reaches the stomach of an individual..

Secretin being released by the duodenum stimulates gastric secretion in the stomach.

Gastric emptying is restricted by the enterogastric reflex.

The fundus region of the stomach is important for the storage of food.

Contractions of the stomach wall do not begin unless the bolus enters the stomach.

The contractions of the stomach depend on activity in the sciatic nerve.

Pancreatic secretion is restricted by gastrin being secreted by the G cells of the antrum.

Pancreatic acinar cells accomodate trypsin.

Cholecystokinin restricts secretion from the exocrine pancreas.

The commencement of acid into the duodenum stimulates pancreatic secretion.

It gets diluted in the gall bladder of an individual.

Hepatic bile salts act as hydrophobic molecules.

Maximum bile salts are reabsorbed in the terminal ileum.

Bile salts are the end products of hemoglobin present in the blood.

The human body cannot store glucose.

All essential amino acids are found in meat.

Plant oils primarily consist of saturated fats.

Normally ketones are found in the urine of a person eating a carbohydrate rich diet.

Adults can synthesize all of the essential amino acids in their bodies.

Children serving with a protein deficient diet may develop kwashiorkor.

Edema is a particular feature of marasmus.

An individual taking a diet low in fats often suffers from fatty acid deficiency diseases.

Intestinal digestive enzymes are secreted by cells of the oxyntic cells.

Approximately 50% of the digested carbohydrate is absorbed in the small intestine.

Small peptides are absorbed in the small intestine.

The liver is the first organ of the digestive system to receive the digestion products of dietary fats.

The presence of enormous fat in the chyme will speed up gastric emptying.

Distension of the ileum triggers gastric motility.

Total gastrectomy leads to malabsorption of vitamin B12 in the body .

Aldosterone restricts the absorption of sodium and water by the large intestine in the digestive system.

Excess intake of vitamin A leads to severe toxic reactions in the body.

Vitamin B2 deficiency leads to severe muscular disorders in an individual.

Vitamin B12 deficiency causes microcytic anemia in females.

Rickets in adults can be prevented by large doses of vitamin D.

Sertoli cells allow the unrestrained diffusion of water-soluble substances between the seminiferous tubules and the blood.
