Ich verstehen nicht, wie ich hier vorgehen soll. Kann mir jemand dabei helfen?
I would say ash, but I'm not sure.
Hallo, ich muss nächsten Jahr in Biologie eine BELL schreiben und habe mich dafür entschieden diese über Anämie (Blutarmut) zu halten, doch leider finde ich keine genaue Themeneingrenzung (Schwangerschaftsanämie, Anämie bei Tumor – Patienten,…) welche sich für eine BELL eignen würde. Das Problem ist, dass dies eine häufig verbreitete ”Krankheit“ ist und es somit schon…
I don't understand why these people who cut down trees don't want to recognize that if they continue like this, for example in the rainforest, the trees will die and so will the animals. We humans will no longer have enough clean air and so we will die too.

google under: partial pressure gradient lung blood…
simplified:
inhale -> an overpressure of oxygen in the lung presses the oxygen into the blood…
an overpressure of CO2 in the blood presses the CO2 into the lung bubbles…-> exhale
thanks!
Thanks to efficient physiological processes that take place in the lung, oxygen reaches the blood quickly. This is how it works:
1. **Inhalation**: During inhalation, air flows into the lungs through the respiratory tract (nase, throat, air tube and bronchi).
Two. **Alveolen**: In the lungs there are small air bubbles called alveolas. These alveolas are surrounded by a network of small blood vessels, the capillaries.
3. **Diffusion**: Oxygen from the inhaled air diffuses through the thin wall of the alveolas and then through the thin wall of the capillaries. This diffusion process is fast as the distance is very small (less than 1 micrometer).
4. **Inclusion of hemoglobin** The red blood cells in the capillaries contain a protein called hemoglobin. Oxygen binds to the hemoglobin and thus allows efficient transport through the blood to the tissues.
Five. Circular**: The heart pumps oxygen-rich blood from the lungs to the rest of the body. Oxygen-rich blood is transported to all organs and tissues via the aorta and other arteries.
This entire process is extremely efficient and takes place within seconds after inhalation of the air. It ensures that oxygen is quickly available to the cells in the body to generate energy through the process of cell breathing.
