Answer: D) precapillary sphincters relax.
Explanation:
Blood flow to a tissue will decrease if precapillary sphincters relax as, capillaries provides glucose and oxygen to the cells and allows blood to flow through it when the muscle ring known as the precapillary Sphincters get relaxed. The blood flow is stopped when the precapillary sphincters constrict flow of blood. As, certain chemical signals causes feeder arterioles to dilate and bring more blood into local areas then, it causes precapillary sphincters to relax.
Explanation:
Aldosterone is steroidal hormone which is produced by outer-section of adrenal cortex in adrenal gland. It acts on distal tubules and the collecting ducts of kidney to cause conservation of the sodium by facilitating the secretion of the potassium and increased water retention.
Atrial natriuretic hormones are natriuretic peptide hormone which are secreted from cardiac atria. Main function of the hormone is causing reduction in the volume of the expanded extracellular fluid by increasing the renal sodium excretion.
<u>Thus, Atrial natriuretic hormones causes sodium and the Water loss while Aldosterone helps in the conservation of the sodium and water retention.</u>
Answer:
According to the American Academy of Pediatrics (AAP), a baby should consume, on average, about 2.5 ounces of formula a day for every pound of their body weight. For example, a 12-pound baby would likely need 30 ounces in a 24-hour period.
