What happens when you push on your bladder?
In anatomy, the urinary bladder is the organ that collects urine excreted by the kidneys prior to disposal by urination. A hollow [1] muscular, and distensible (or elastic) organ, the bladder sits on the pelvic floor. Urine enters the bladder via the ureters and exits via the urethra.
Embryologically, the bladder is derived from the urogenital sinus and, it is initially continuous with the allantois. In males, the base of the bladder lies between the rectum and the pubic symphysis. It is superior to the prostate, and separated from the rectum by the rectovesical excavation. In females, the bladder sits inferior to the uterus and anterior to the vagina. It is separated from the uterus by the vesicouterine excavation. In infants and young children, the urinary bladder is in the abdomen even when empty.[2]
Why would you need a bladder sling?
Bladder sling is mainly used to treat stress urinary incontinence in women. A synthetic or organic sling is used to support and raise the neck of the bladder and the urethra. This operation is called bladder neck suspension surgery.
What effect does acth have on the kidneys?
Well, ACTH (aka adrenocorticotropic hormone or corticotropin) could ameliorate edema associated with kidney disease, lower protein excretion in the urine (proteinuria), correct hyperlipidemia and protect kidney function in patients with nephrotic syndrome caused by a variety of glomerular diseases.
What is a artificial kidney machine called?
An artificial kidney machine is called a dialysis machine. It functions to perform the functions of the kidneys when they are unable to do so effectively, such as filtering waste products and excess fluids from the blood.
What is an partially distended bladder?
A partially distended bladder occurs when the bladder is not completely full but is not fully empty either. This can happen due to various reasons, including urinary retention or incomplete emptying of the bladder. It can lead to symptoms like frequent urination or discomfort.
What does it mean to have a spot on my bladder?
Having a spot on your bladder typically refers to a lesion, growth, or abnormality detected during a medical imaging test like an ultrasound or CT scan. It could be due to various causes such as infection, inflammation, or more serious conditions like tumors. Further evaluation by a healthcare provider is needed to determine the exact nature of the spot and appropriate treatment.
What are the two bladders in the body?
The two bladders in the body are the urinary bladder, which stores urine until it is expelled from the body, and the gallbladder, which stores and concentrates bile produced by the liver until it is needed for digestion.
Is it better to have a full bladder with sonogram?
Yes, having a full bladder before a sonogram can help improve the quality of the images obtained. The full bladder pushes the uterus up and helps to provide a clearer view of the pelvic organs during the scan.
Did pete burns die from kidney failure?
No, Pete Burns did not die from kidney failure. He has starred on TV interviews in 2010, and there are pictures of him somewhere in 2011.
What is the role of kidney in excretion?
The kidney plays a vital role in excretion by filtering waste products, excess water, and electrolytes from the blood to form urine. It helps maintain the body's overall balance of fluids and electrolytes by regulating their levels in the urine. Additionally, the kidney helps remove toxins and metabolic byproducts from the body, contributing to overall waste elimination.
The cells in the distal convoluted tubule that monitor changes in urine volume and osmolarity are known as macula densa cells. They are sensitive to the concentration of sodium chloride in the filtrate passing through the tubule and help regulate blood pressure and fluid balance in the body.
Does partial removal of a kidney affect the patient with lifetime problems such s UTI'S?
A partial nephrectomy does have long-term consequences, most especially indeed for those with a history of recurrent urinary tract infections (u.t.i.): the problem arises because partial nephrectomy inevitably leads to damage to the anatomical area of the kidney known as the pelvis, which is the area into which the urine drains before passage down the ureter. Such damage and scar-tissue formation leads to distortion of the pelvis, with consequences for the flow of urine from the area, including stagnation. In the presence of infectious micro-organisms, such stagnation can cause UPPER urinary tract infections, with the increased risk of pyelo-nephrititis; or infectious involvement of the kidney tissue itself. This can become a chronic infection, or recurrent acute on chronic disease, and lead to a reduction in functioning renal tissue.
Does a fever increase or decrease the specific gravity of urine?
fever increases specific gravity of urine because when a person has fever , that person sweats alot which leads to increase in solute concentraion of body and hence more solute will be in urine . therefore making specific gravity of urine higher in person with fever
Substances larger than c. albumin are normally not allowed to pass through the filtration membrane.
What is the function of the urethra in a cat?
The urethra in a cat serves as a tube that carries urine from the bladder to the outside of the body. It plays a crucial role in the excretory system by allowing the cat to eliminate waste fluids from its body.
What are the signs and symptoms of bladder stones?
There are no symptoms for kidney stones once they reach the bladder. They are effectively on their way out of the body through the urethra.
When lodged in the ureter on the way to the bladder, kidney stones generate two major symptoms. The primary one is moderate to severe pain felt in the lower back, which increases unless the stone passes. A second common symptom is the urge to urinate when the bladder is already empty.
The first sign, which is usually apparent only to those who have already experienced a kidney stone, is a small twinge of discomfort on either side of the lower back (the side the stone may form in). This can also be caused by thickening of kidney fluids, triggered by insufficient water intake or by certain compounds removed by the kidney.
What are the three basic physiological processes in urine formation?
Every one of us depends on the process of urination for the removal of certain waste products in the body. The production of urine is vital to the health of the body. Most of us have probably never thought of urine as valuable, but we could not survive if we did not produce it and eliminate it. Urine is composed of water, certain electrolytes, and various waste products that are filtered out of the blood system. Remember, as the blood flows through the body, wastes resulting from the metabolism of foodstuffs in the body cells are deposited into the bloodstream, and this waste must be disposed of in some way. A major part of this "cleaning" of the blood takes place in the kidneys and, in particular, in the nephrons, where the blood is filtered to produce the urine. Both kidneys in the body carry out this essential blood cleansing function. Normally, about 20% of the total blood pumped by the heart each minute will enter the kidneys to undergo filtration. This is called the filtration fraction. The rest of the blood (about 80%) does not go through the filtering portion of the kidney, but flows through the rest of the body to service the various nutritional, respiratory, and other needs that are always present.
What known functions result from sympathetic innervation into kidneys?
Sympathetic innervation into the kidneys can lead to several functions such as vasoconstriction of renal blood vessels, stimulation of renin release from the juxtaglomerular cells, and reduction in urine production by decreasing blood flow to the kidneys. These responses help regulate blood pressure and maintain overall body fluid balance.
What Polysaccharide substance is used to determine Glomerular Filtration Rate?
Inulin is a polysaccharide substance commonly used to determine glomerular filtration rate (GFR) as it is freely filtered by the glomerulus and neither reabsorbed nor secreted by the renal tubules. Inulin clearance is considered to be the most accurate measure of GFR.
Is peritubular fluid is same with interstitial fluid?
Peritubular fluid refers specifically to the fluid found in the renal tubules of the kidney, while interstitial fluid is found in the spaces surrounding cells throughout the body, including the kidney. While they both play a role in transporting substances and maintaining homeostasis, they are located in different anatomical compartments.
In the urinary system what does the term secretion refer to?
In the urinary system, secretion refers to the process by which certain substances are actively transported from the blood into the renal tubules to be ultimately excreted in urine. This process helps in regulating the composition of urine and maintaining overall fluid balance in the body.
What is punctate erythema in the bladder?
Punctate erythema in the bladder refers to small red spots or patches that are observed on the lining of the bladder during a medical examination, such as cystoscopy. It can indicate inflammation, irritation, or infection in the bladder. Further investigation may be needed to determine the underlying cause and appropriate treatment.
How does the giraffes excretory system work?
Giraffes have a similar excretory system to other mammals. They eliminate waste through their kidneys, which filter blood to produce urine. The urine is then stored in the bladder and excreted through the urethra. Giraffes also have specialized adaptations in their kidneys to help conserve water in their arid habitats.
Fungi feed using enzymes and absorption. The hyphae of fungi, are able to screte digestive enzymes out into the soil or other surrounds in which they grow. The ezymes then digest and breakdown the "food". The digested mass is then reabsorbed by the hyphae and used by the fungi.
This is also known as extracellular digestion.
