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!
Answer:
Hyponatremia
Explanation:
In medicine, hyponatremia refers to a medical condition where there's a low level of sodium in the blood.
One of the main causes for hyponatremia is having prolonged periods of exercise (and therefore sweating a lot) combined with drinking large volumes of water without electrolytes. Because of the sweating and the large volumes of water, the kidneys start malfunctioning and they can't regulate the amounts of sodium properly.
In this example, <u>a person works outside in a physically demanding job in August, sweats a lot and consumes large volumes of water throughout the day,</u> we can see that this person meets the criteria mentioned in the previous paragraph to develop signs of hyponatremia.
