Answer 2
Final answer:

The venae cavae return oxygen-depleted blood to the heart while the aorta carries oxygen-rich blood away from the heart.

Explanation:

The functions of the venae cavae and the aorta differ in terms of the circuits they serve in the circulatory system.

The venae cavae are responsible for returning oxygen-depleted blood from the body's tissues back to the heart. The superior vena cava drains blood from veins above the diaphragm, while the inferior vena cava drains blood from veins below the diaphragm.

On the other hand, the aorta is the largest artery in the body and carries oxygen-rich blood away from the heart to supply it to the body's tissues through the systemic circuit. It branches into various regions to deliver blood to different parts of the body.

"If I have changes in my vision, I will lie down and rest."

Answer:

"If I have changes in my vision, I will lie down and rest."

Explanation:

Pregnancy presupposes the growth of a genetically different being within a woman's womb, as she has inherited half of her father's genes. She does not reject this foreign body because it develops immune mechanisms to protect the fetus. In some cases, however, it releases proteins into the maternal circulation that trigger a pregnant woman's immune response. This response strikes the walls of blood vessels, causing vasoconstriction and increased blood pressure.  Pregnancy-specific hypertension is called preeclampsia and usually sets in after the 20th week, especially in the 3rd trimester.

Preeclampsia is a serious condition, but it can be controlled with good prenatal care and medical follow-up. In addition, the pregnant woman should take some precautions according to the recommendations of her doctor. If the pregnant woman has changes in vision, she should not lie down and rest, but should call for medical or emergency care as soon as possible.
