Development of Human Microbiota01:30

Development of Human Microbiota

The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from the skin...
Development of the Oral Microbiota01:28

Development of the Oral Microbiota

The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
Anatomy of the Intestines01:53

Anatomy of the Intestines

Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.Small IntestinesThe small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the small intestine...
Parental Care01:37

Parental Care

Many animals exhibit parental care behavior, including feeding, grooming, and protecting young offspring. Parental care is universal in mammals and birds, which often have young that are born relatively helpless. Several species of insects and fish, as well as some amphibians, also care for their young.
Social-Contextual Approach01:24

Social-Contextual Approach

The social-contextual approach, grounded in Vygotsky’s sociocultural theory, emphasizes the influence of cultural and environmental contexts on cognitive development. From birth, caregivers act as mediators of culture, transmitting values, skills, and practices that shape how children grow and learn.Cultural Influences on Caregiving PracticesChild-rearing practices reflect broader cultural ideals about independence and interdependence. In individualistic societies, parents often sleep...
Taste During Infancy01:20

Taste During Infancy

The sense of taste begins developing before birth and is shaped by biological predispositions and early experience. During pregnancy, flavors from foods consumed by the mother can enter the amniotic fluid, exposing the fetus to different flavors. These prenatal experiences may contribute to food preferences after birth.Prenatal and Breastfeeding InfluencesAfter birth, flavors from a mother’s diet can also pass into breast milk. Repeated exposure to these flavors during breastfeeding may make...
