Question

it has been suggested that humans and microbes are completely interconnected and involved in the development and maintenance of which following systems? check all that apply.
check all that apply
skeletal system
immune system
digestive system
cardiovascular system

Explanation:

• The skeletal system relies on microbes (like those aiding nutrient absorption for bone health) and microbial signaling for development/maintenance.
• The immune system co-develops with commensal microbes, which train immune cells and regulate responses.
• The digestive system hosts the majority of human-associated microbes, which aid digestion, produce nutrients, and maintain gut barrier function.
• The cardiovascular system is impacted by microbial metabolites (like short-chain fatty acids) that regulate blood pressure and heart health, and microbes play a role in cardiovascular development and disease prevention.

Answer:

☐ Skeletal system
☐ Immune system
☐ Digestive system
☐ Cardiovascular system
