The atrium of the heart secretes _____________.

Answers

Answer 1

Answer:

The correct answer will be- Atrial natriuretic factor (ANF).

Explanation:

The atrium of the heart plays important role in regulating the blood volume and blood pressure. The mechanical stretching of the atria leads to the release of an important hormone called atrial natriuretic factor.

ANF acts by increasing the excretion of sodium and inhibition of renin in the kidney as well as antagonizing vasoconstriction and shifting the fluid from intravascular to the interstitial compartment in the cardiovascular system.

Thus, Atrial natriuretic factor is the correct answer.

In a healthy adult, blood pressure at the union of the vena cavae and right atrium is about 80 mm Hg.
a. True
b. False

Answers

I believe it’s true

Final answer:

The statement regarding blood pressure at the union of the vena cavae and right atrium being about 80 mm Hg is false; this value is much lower and close to 0 mm Hg, while the normal systemic arterial blood pressure should be around 120/80 mm Hg.

Explanation:

The statement that in a healthy adult, blood pressure at the union of the vena cavae and right atrium is about 80 mm Hg is false. The pressure at this junction, known as the central venous pressure, is much lower than systemic arterial blood pressure and is usually close to 0 mm Hg in a healthy individual. The normal blood pressure for a healthy adult is typically stated as 120/80 mm Hg, where 120 mm Hg represents the systolic pressure and 80 mm Hg represents the diastolic pressure. The blood pressure values mentioned in the question are reminiscent of the systemic arterial pressure, not the pressure at the vena cavae and right atrium. Moreover, it is the systolic and diastolic pressures that are measured when a healthcare professional checks arterial blood pressure, not venous pressure.

An individual who meets the threshold criteria for the risk factor of prediabetes should be considered to have a metabolic disease.
a. True
b. False

Answers

Answer:

b. False

Explanation:

Pre-diabetes is the clinical situation that precedes the diagnosis of type 2 diabetes. At this point, the body begins to show signs, mainly through blood tests, that sugar (blood glucose) levels are starting to get high, and insulin levels too. Pre-diabetes is well known for its state of insulin resistance, when the pancreas starts producing too much insulin in an attempt to control sugar levels. The patient who has pre-diabetes cannot be diagnosed with the disease, because being pre-diabetic does not mean being diabetic, but it does mean that there is a great chance that in the future (perhaps near) this patient will develop the metabolic disease.
