What conditions promote edema?
Causes may include venous insufficiency, heart failure, kidney problems, low protein levels, liver problems, deep vein thrombosis, infections, angioedema, certain medications, and lymphedema. It may also occur after prolonged sitting or standing and during menstruation or pregnancy.
Which of the following would not be expected to lead to edema?
Which of the following would NOT be expected to lead to edema? Hyponatremia is low levels of sodium in the blood. This can lead to dehydration, not edema.
What does hypotonic hydration refers to?
The term hypotonic hydration refers to. A CONDITION THAT MAY RESULT FROM RENAL INSUFFICIENCY. Hypoproteinenemia is a condition of unusually low levels of plasma proteins. This problem is often characterized by. TISSUE EDEMA.
What is the most important trigger for aldosterone?
Serum potassium concentrations are the most potent stimulator of aldosterone secretion. the ACTH stimulation test, which is sometimes used to stimulate the production of aldosterone along with cortisol to determine whether primary or secondary adrenal insufficiency is present.
Which of the following condition causes metabolic alkalosis?
Metabolic alkalosis is caused by too much bicarbonate in the blood. It can also occur due to certain kidney diseases. Hypochloremic alkalosis is caused by an extreme lack or loss of chloride, such as from prolonged vomiting.
Which of the following would not be expected to occur as a result of dehydration quizlet?
Which of the following would NOT be expected to occur as a result of dehydration? B (edema. Edema is tissue swelling that results from an atypical accumulation of fluid in the interstitial space. During dehydration, this fluid would be reduced.)
What conditions stimulate aldosterone release?
Aldosterone secretion is stimulated by an actual or apparent depletion in blood volume detected by stretch receptors and by an increase in serum potassium ion concentrations; it is suppressed by hypervolemia and hypokalemia.
Which of the following conditions would trigger the release of the hormone aldosterone?
Aldosterone is part of a group of linked hormones, which form the renin–angiotensin–aldosterone system. Activation of this system occurs when there is decrease in blood flow to the kidneys following loss of blood volume or a drop in blood pressure (e.g. due to a haemorrhage).
What hormone triggers the release of aldosterone?
Renin is responsible for the production of angiotensin, which then causes the release of aldosterone. Once the body is rehydrated and has proper salt levels in the blood, renin levels fall, and aldosterone levels lower as a result.
What stimulates cortisol release?
Adrenocorticotropic hormone (ACTH) is produced by the pituitary gland. Its key function is to stimulate the production and release of cortisol from the cortex (outer part) of the adrenal gland.
What stimulates ACTH release?
CRH is released from the hypothalamus. CRH stimulates the anterior pituitary to release ACTH. ACTH acts on the adrenal cortex to release cortisol and androgens. The increase in cortisol provides a negative feedback system to decrease the amount of CRH released from the hypothalamus.
What stimulates the release of epinephrine and norepinephrine?
When a stressor begins, epinephrine and norepinephrine are released from the adrenal medulla and norepinephrine is released from the sympathetic nerve terminals. Because the secretory cells are neurons, catecholamine release is very quick and effects can be seen in less than a second.
What are the four main functions of cortisol?
Because most bodily cells have cortisol receptors, it affects many different functions in the body. Cortisol can help control blood sugar levels, regulate metabolism, help reduce inflammation, and assist with memory formulation. It has a controlling effect on salt and water balance and helps control blood pressure.
What hormone promotes water retention by the kidneys?
Antidiuretic hormone (ADH) induces water retention by increasing the permeability of nephrons.
What is the function of ACTH?
ACTH is a hormone made by the pituitary gland, a small gland at the base of the brain. ACTH controls the production of another hormone called cortisol.
What is cortisol effect?
Cortisol, the primary stress hormone, increases sugars (glucose) in the bloodstream, enhances your brain’s use of glucose and increases the availability of substances that repair tissues. Cortisol also curbs functions that would be nonessential or harmful in a fight-or-flight situation.
How does cortisol increase blood glucose?
Under stressful conditions, cortisol provides the body with glucose by tapping into protein stores via gluconeogenesis in the liver. This energy can help an individual fight or flee a stressor. However, elevated cortisol over the long term consistently produces glucose, leading to increased blood sugar levels.
