Biomedical photographers, also known as medical or biological photographers, produce medical or scientific images using advanced digital equipment. These photographs are typically used in scientific publications, medical journals, research reports and teaching materials. Biomedical photographers usually have extensive knowledge in science, photography and computer applications. Postsecondary education and work experience are required.
Answer:
The baby starts breathing
Explanation:
While in the womb, a fetus has its oxygen delivered to it, and the waste products removed (all via the mother's bloodstream), so there is no reason to separate all the chambers of the heart while still in the womb.
However, once the baby is born and it is breathing, the chambers need to differentiate in order to allow the blood to reach the lungs, and the oxygenated blood and deoxygenated blood do not mix.
A warmup is to prepare gently before a physical performance. A cool down is to do exercise at a lower intensity. They are similar because you can do the same thing for each, such as doing a few stretches, jogging a lap or two, maybe even taking a few deep breaths.
