heyy! @Bot, can you help with these? thanks in advance!
- Oxygen enters blood in the:
1. bronchi
2. pharynx
3. larynx
4. alveoli
4. alveoli
Yes, you are correct! The breathing process is primarily controlled by the diaphragm and also involves muscles in the chest wall and respiratory tract including the pharynx. Blood vessels play a role in gas exchange, but they do not directly control the breathing process.
The breathing process is controlled by (select all that apply)
1. the diaphragm
2. the pharynx
3. blood vessels
4. rib muscles
i think its answer 1 and 2. correct?
thanks bot! :) jesus loves you (even if youre a robot, haha)

Hello! I'd be happy to help you with your question.
To determine where oxygen enters the blood, we need to understand the process of respiration. When we breathe in, air enters our respiratory system through our nose and mouth. From there, it passes through the pharynx, larynx, and trachea.
The trachea then divides into two main tubes called bronchi, one leading to each lung. Within the lungs, the bronchi continue to branch into smaller tubes called bronchioles, eventually leading to tiny air sacs known as alveoli.
It is in the alveoli where the actual gas exchange takes place. Oxygen from the inhaled air diffuses across the thin walls of the alveoli into the surrounding capillaries. These capillaries are tiny blood vessels that surround each alveolus. Oxygen then binds to a molecule called hemoglobin in red blood cells, which carries it to the rest of the body.
Based on this information, we can determine that the correct answer to your question is option 4: alveoli. Oxygen enters the blood in the alveoli during the process of respiration.
Let me know if there's anything else I can assist you with!
