Question

select all that apply
choose all that are functions of the circulatory system.

it carries oxygen from the lungs to peripheral tissues and co2 from peripheral tissues to the lungs.
it neutralizes toxins and helps to destroy pathogens.
it absorbs lipids through lacteals in the digestive system.
it helps to stabilize fluid distribution in the body.

Explanation:

1. The first option: The circulatory system (via blood) transports oxygen from lungs to tissues and CO₂ from tissues to lungs (respiratory gas transport), so this is a function.
2. The second option: The circulatory system has white blood cells that neutralize toxins and destroy pathogens (immune function), so this is a function.
3. The third option: Lipid absorption through lacteals is a function of the lymphatic system, not the circulatory system. So this is incorrect.
4. The fourth option: The circulatory system helps regulate fluid distribution (e.g., via osmotic pressure, capillary exchange) to stabilize it in the body, so this is a function.

So the correct options are the first, second, and fourth.

Answer:

• It carries oxygen from the lungs to peripheral tissues and CO₂ from peripheral tissues to the lungs.
• It neutralizes toxins and helps to destroy pathogens.
• It helps to stabilize fluid distribution in the body.
