Question

Blood pressure falls 5-15 mm Hg in systolic and diastolic pressures during the second trimester, although it returns to near normal levels at term.

a) Cardiovascular system
b) Respiratory system
c) Endocrine system
d) Renal system

Answer 1

Blood pressure comprises systolic and diastolic pressures and is critical for cardiovascular health. During the second trimester of pregnancy, it usually drops by 5-15 mm Hg but normalizes by the end of the pregnancy. Both high and low blood pressure levels can signal health concerns.

So, the correct answer is a) Cardiovascular system.

Step-by-step explanation:

Blood pressure is a key indicator of cardiovascular health and is measured as a combination of systolic and diastolic pressures. These measurements indicate the force of the blood against artery walls during heart contraction and relaxation, respectively. Systolic pressure typically has a desirable range of 100 to 120 mm Hg, while optimal diastolic pressure is about 80 mm Hg. Blood pressure can be affected by various factors, including hormonal changes, stress, physical activity, and body position.

During the second trimester of pregnancy, blood pressure normally declines by 5-15 mm Hg for both systolic and diastolic pressures. This dip is temporary and generally levels out to near-pre-pregnancy measurements by term. It is essential for maintaining proper circulatory function and fluid balance within the body, with high or low extremes indicating potential health issues.

So, the correct answer is a) Cardiovascular system.
