Respiratory System
The respiratory system allows your body to take in oxygen and remove carbon dioxide. Oxygen supports energy production, brain function, and survival at the cellular level. Without efficient breathing, other body systems struggle to function well.
Key organs include the nose, trachea, lungs, and diaphragm. Air enters through the nose, travels down the airways, and reaches the lungs where gas exchange occurs and the diaphragm contracts and flattens during inhalation, then relaxes and domes upward during exhalation. Oxygen moves into the blood. Carbon dioxide leaves the body.
Healthy lungs depend on clean air, physical activity, and early attention to breathing problems. Smoking, air pollution, untreated infections, and poor ventilation weaken this system over time.

β¨WHO has officially validated Brazil for eliminating mother-to-child transmission of HIV β making it the largest country in the Americas to reach this milestone.
*How Brazil did it:*
β Reduced HIV transmission in pregnancy to below 2%
β Achieved more than 95% coverage for prenatal care, HIV testing & timely treatment
β Ensured strong data systems, human-rights-based care & community engagement
β Delivered free, universal care through SUS β Brazilβs public health system
π This achievement protects mothers and babies, and shows what is possible when countries commit to equitable, high-quality health care for all.
π Over the last decade, more than 50,000 pediatric HIV infections were prevented across the Americas thanks to regional efforts.
*What we can all support:*
β Early prenatal care
β Routine HIV testing
β Access to treatment for all pregnant women
β Health systems that leave no one behind
ππ Every child deserves to be born HIV-free.

βAstronauts in space experience zero gravity.β
I don't why most chose True
The correct answer is false
Astronauts do experience gravity in space.
If gravity were truly zero, the Moon wouldnβt orbit Earth and satellites would fly off into space.
So why do astronauts float?
They float because they are in continuous free fall, not because gravity is gone.
The International Space Station (ISS) is pulled toward Earth by gravity.
At the same time, itβs moving sideways very fast.
This creates orbit, meaning everything inside is falling together.
This condition is called microgravity, not zero gravity.
