Epinephrine primarily impacts the kidneys by causing vasoconstriction of renal blood vessels, which reduces renal blood flow and glomerular filtration rate. This response is part of the "fight or flight" reaction, prioritizing blood flow to vital organs and muscles. Additionally, epinephrine stimulates the release of renin from the juxtaglomerular cells, promoting the renin-angiotensin-aldosterone system (RAAS), which further influences blood pressure and fluid balance. Overall, these effects can lead to decreased urine output during stress responses.

What does physiologic uptake is seen in the kidneys mean?
Physiologic uptake in the kidneys refers to the normal and expected absorption of a substance, such as a radiotracer during imaging studies, indicating healthy kidney function. This uptake is typically assessed in procedures like renal scans, where the kidneys actively filter the tracer from the bloodstream. Observing physiologic uptake suggests that the kidneys are functioning properly, as they effectively process and excrete substances. Abnormal uptake patterns may indicate potential issues, such as renal impairment or disease.
How long do the side effects of epinephrine last?
hoe long does epinephrine last in the system after injection?
Amphetamines mimic the effects of the neurotransmitter?
epinephrine
What chemical released near your kidneys speed up your heart?
Adrenaline. It has another name, Epinephrine. Comes from the adrenal glands located superior to the kidneys.
What makes racemic epinephrine more effective?
Because it causes less cardiovascular side effects than common epinephrine
Side effects of epinephrine in anaphylaxis?
tachycardia and possible dizziness
What gland activates by sympathetic nervous system produces epinephrine and helps the kidneys regulate sodium and potassium in blood and helps kidneys regulate the water balance?
The adrenal glands
What is physiologic radiotracer uptake is present?
Physiologic radiotracer uptake refers to the normal uptake of a radiotracer by organs or tissues in the body that is expected due to their physiological functions. This can include uptake by organs like the heart, liver, kidneys, and brain. Understanding physiologic radiotracer uptake is important in interpreting nuclear medicine imaging studies and distinguishing normal uptake from abnormal findings.

What are catacholamines?
cat.e.cho.la.mine (kt-kl-mn, -kô-) n. Any of a group of amines derived from catechol that have important physiological effects as neurotransmitters and hormones and include epinephrine, norepinephrine, and dopamine.
Can you overdose on epinephrine?
Yes, it is possible to overdose on epinephrine, which can lead to serious side effects such as increased heart rate, high blood pressure, and potentially life-threatening complications. It is important to use epinephrine as directed by a healthcare professional.
What does physiologic activity within the kidneys and urinary bladder mean?
Physiologic activity within the kidneys and urinary bladder refers to the essential functions they perform to maintain homeostasis in the body. The kidneys filter blood to remove waste products and excess fluids, regulate electrolyte balance, and control blood pressure through the production of urine. The urinary bladder then stores this urine until it is excreted from the body. Together, these processes play a crucial role in fluid balance, waste elimination, and overall health.
