Juxtaglomerular cells of the juxtaglomerular apparatus secrete _______________ when _______________.
Anna11 [10]

Answer:

The correct answer will be option-D

Explanation:

In case the blood pressure drops in the body, the juxtaglomerular cells of the kidney start converting the prorenin into renin. This renin converts inactive angiotensin to angiotensin I which gets converted to angiotensin II by ACE enzyme.

The angiotensin II acts as vasoconstrictor narrowing the vessels and thus increasing the blood pressure. It also stimulates the secretion of aldosterone which increases the reabsorption of sodium ions and help increase the blood pressure of the blood.

Thus, option-D is the correct answer.

Infection caused by __________ is of greatest concern to pregnant women and those with compromised immune systems.
Anarel [89]

Answer:

<em>Listeria</em>

Explanation:

<em>Listeria</em> causes invasive syndromes such as meningitis, sepsis, and stillbirth in pregnant or immunosuppressed people. It is an intracellular pathogen and affects the persons with deficient cell-mediated immunity. Bacteria from this genus are part of the normal gastrointestinal microbiota in healthy individuals. However, in immunosuppressed individuals, the bacterium uses proteins such as internalin and phospholipase C for invasion, intracellular multiplication, and cell-to-cell spread.

Pregnant women are at the increased risk of infection due to both systemic and local immunological changes that mostly occur during pregnancy. For example, local immunosuppression at the maternal-fetal interface of the placenta may support the intrauterine infection.
