Answer:
3 is the answer the right choice.
It regulates temperature, glucose, toxins, blood pressure, and pH.
<span>
TemperatureThe body must maintain a relatively constant temperature. If it gets too hot, the body employs vasodilation to cool down. This dilates the blood vessels, allowing more heat to escape from them through the skin.
GlucoseThe body must regulate glucose levels to stay healthy. When glucose levels become too high, the body releases a hormone called insulin. When they become too low, the body converts the glycogen in the blood to glucose.
ToxinsToxins in the blood can disrupt the body's homeostasis. Thus, it signals the urinary system to ensure that the toxins are excreted.
Blood PressureThe body must maintain healthy levels of blood pressure. To do so, the brain sends signals to the heart to speed up or slow down according to the blood pressure.
pHThe lungs control the pH amount in the body. If pH levels become unbalanced, the lungs push more or less carbon dioxide out of the diaphragm. This can raise or lower pH levels in the body.</span>

Hello!
Hemoglobin is the protein which carries oxygen by binding to it. Hemoglobin is found in red blood cells. This protein is extremely important as it allows respiration to be carried out, and transports oxygen to the rest of our bodies.
Oxygen diffuses from the alveoli (in our lungs) through capillaries into the blood. From there, the hemoglobin in the blood will take the oxygen, and bring it to the other parts of the body which need it. This also allows continued diffusion into the capillaries.
Hope this helps!
