How does juxtaglomerular apparatus help regulate blood pressure and filtration rate?
The apparatus is a microscopic structure in the kidney, the specific location of it helps to regulate the renal blood flow and filtration rate. It is regulated by secreting renin which activates the
First implanted in humans in 1958?
The first implantable pacemaker was first implanted in humans in 1958 by Dr. Ake Senning in Sweden. This revolutionary device helps regulate heart rhythms and has since saved countless lives worldwide.
What is a pinch cock?
A pinch cock is a type of valve that controls the flow of fluid by pinching a flexible tubing to restrict or stop the flow. This mechanism is typically used in laboratory or medical settings to regulate the movement of liquids or gases.
What role do pacemakers play in helping the heart beat and pump blood?
Pacemakers are small devices implanted in the chest to regulate the heart's rhythm. They send electrical signals to the heart to help it beat at a steady pace and pump blood effectively.
What is the juxtaglomerular apparatus in the body?
The juxtaglomerular apparatus is a specialized structure found in the kidney that regulates blood pressure and kidney function. It consists of the macula densa, juxtaglomerular cells, and extraglomerular mesangial cells, which work together to control the release of renin and the constriction of blood vessels.
What is the juxtaglomerular apparatus responsible for?
The juxtaglomerular apparatus is responsible for regulating blood pressure and kidney function. It consists of specialized cells in the afferent arteriole and the distal convoluted tubule that sense changes in blood pressure and help regulate the secretion of renin, which plays a key role in the renin-angiotensin-aldosterone system.
Why sa mode known as peacemaker?
the SA node (sinoatrial node) stimulates the heart to beat @ a particular rate. when this node causes the heart to beat too fast or too slow or irregularly, a pacemaker (a small mechanical device) is surgically implanted under the skin of the chest to regulate the heartbeat.
What happens in deep brain stimulation?
In deep brain stimulation, electrodes are surgically implanted in specific areas of the brain and connected to a device similar to a pacemaker. Electrical impulses are then delivered to these areas to help regulate abnormal brain activity and improve symptoms of movement disorders like Parkinson's disease or essential tremor. This treatment can help reduce symptoms such as tremors, stiffness, and difficulty with movement.
What is the treatment when the AV and SA nodes fail?
If the AV and SA nodes fail, a pacemaker may be implanted to regulate the heart's rhythm. In severe cases, a heart transplant may be necessary. Medications to control heart rate and rhythm may also be prescribed.
What is the present tense of regulate?
It is "regulate/regulates".
Is glucagon synthesized in the rough er?
Yes, glucagon is synthesized in the rough endoplasmic reticulum (ER) of pancreatic alpha cells. It is then processed through the Golgi apparatus before being released into the bloodstream where it helps regulate blood sugar levels by promoting the release of glucose from the liver.
What part of the heat liberating apparatus of the body?
Part of the heat liberating apparatus of the body is the eccrine sweat gland. Eccrine sweat glands are found in the skin, mostly on the palms of the hands and the soles of the feet.
