Endocrine gland(s) Group of answer choices secrete substances that do not alter the metabolism of their target cells, but have extracellular effects. secrete their products by way of ducts. have an unusually low density of blood capillaries. release their secretions directly into the blood. secretions may be released into the body surface.

The correct answer is: Release their secretions directly into the blood.

Explanation:

Glands are organs that regulate bodily functions by producing and releasing certain substances. Endocrine glands are a type of gland that specifically releases its product into the bloodstream.

Endocrine glands' products are called hormones and they travel through the blood vessels in order to reach their destination (the organ where they are supposed to act),

An example of an endocrine gland is the pancreas. The pancreas produces insulin and glucagon, two different hormones that act in different organs to regulate glucose levels.

hypoxemia refers to a below usual concentration of oxygen in the blood, mainly in the arteries. hypoxemia is an indication of an issue associated with circulation or breathing and may lead to various symptoms like shortness of breath.  

the condition is identified by determining the level of oxygen in the blood sample obtained from an artery. it can also be predicted by determining the oxygen saturation of the blood with the application of a pulse oximeter.  

the normal arterial oxygen is about 75 to 100 mm hg. the values underneath 60 mm hg is generally considered with the requirement for supplemental oxygen. the normal pulse oximeter readings generally range between 95 to 100 percent. the values under 90 percent are regarded as low.  

in the given case, the oxygen saturation is measured at 93 percent, hence, there is no need to administer oxygen, that is, one should withhold oxygen.
