Anatomy of the kidney and bladder

They are about 25 cm in length each in an adult human. The bladder sits in your pelvis between your hip bones.

This image shows the kidneys ureters and bladder.

Anatomy of the kidney and bladder. Each nephron consists of a ball formed of small blood capillaries called a glomerulus and a small tube called a renal tubule. Urea together with water and other waste substances forms the urine as it passes through the nephrons and down the renal tubules of the kidney. These narrow tubes carry urine from the kidneys to the bladder.

Anatomy of the Kidneys Ureter and Bladder Richard L. McBride Kidneys The kidneys are located in the retroperitoneal connective tissue of the posterior abdominal wall. They develop as pelvic organs that ascend to their final position in the abdomen.

An inset shows the renal tubules and urine. The uterus is also shown. Anatomy of the female urinary system showing the kidneys ureters bladder and urethra.

Urine is made in the renal tubules and collects in the renal pelvis of each kidney. The urine flows from the kidneys through the ureters to the bladder. Urine is made up of this filtered waste and water.

The kidneys work constantly to filter your blood. As the kidneys produce urine it is stored for a short time in the middle of each kidney in a small area called the renal pelvis. The renal pelvis inside each kidney is connected to the bladder by a long thin tube called a ureter.

Gross Anatomy of the Ureters Bladder and Urethra The ureters are present bilaterally on both sides connecting to each kidney. They are about 25 cm in length each in an adult human. Renal System Anatomy.

This image shows the kidneys ureters and bladder. The bean-shaped kidneys are about the size of a closed fist. They lie against the back of the abdominal wall outside the peritoneal cavity which contains all of the bowels just above the.

Generally the bladder is a hollow muscular and pear-shaped distensible elastic organ that sits on the pelvic floor. It receives urine via the ureters which are thick tubes running from each kidney down to the superior part of the bladder. Urine is collected in the body of the bladder and finally it is voided through the urethra.

Urine is made in the kidneys and travels down two tubes called ureters to the bladder. The bladder stores urine allowing urination to be infrequent and controlled. The bladder is lined by layers.

The detrusor muscle comprises the wall of the urinary bladder. It forms the internal urethral sphincter around the neck of the bladder. The detrusor muscle contracts around the ureteric orifices when the bladder contracts in order to prevent vesicoureteral reflux backflow of urine into the ureters.

From the renal pelvis urine drains into the ureter which transports it to the bladder for storage. The medial margin of each kidney is marked by a deep fissure known as the renal hilum. This acts as a gateway to the kidney normally the renal vessels.

In chicken you will not find any urinary bladder as in mammals. This feature reduces the bodyweight of a chicken and thus facilitates flight. The urinary component of chicken excreates together with feces.

There are right and left. As the kidneys ascend into the abdomen the ureteric openings move cranially. The mesonephric ducts Wolffian ducts move caudally and closer together entering the prostatic urethra to become the ejaculatory ducts.

As the kidneys ascend into the. Thin tubes of muscle that connect your kidneys to your bladder and carry urine to the bladder. A hollow muscular balloon-shaped organ that expands as it fills with urine.

The bladder sits in your pelvis between your hip bones. A normal bladder acts like a reservoir. It can hold 15 to 2 cups of urine.

Acute renal failure is rapid onset of azotemia ie elevated blood urea nitrogen BUN and creatinine Cr combined with oliguria or anuria. Azotemia can occur by itself in which case a patient has an elevated BUN and creatinine but normal urine output. Therefore the difference between azotemia and acute renal failure is the amount of urine output normal with azotemia.

The kidney filters the blood of solutes and then secretes concentrates and excretes urine into the lower urinary tract via the ureters. The ureters carry urine approximately 22-30cm from the kidneys to the bladder for elimination. Gravity and peristaltic waves within the ureters propel urine from one end to the other13.

Main Difference Bladder vs Kidney. Bladder and kidney are two vital organs in the urinary system of animals. Bladder is a hollow muscular organ that occurs in the pelvic floor.

Kidneys are bean-shaped organs located below the rib cage on either side of the spine. Each kidney of the adult human weighs about 150 grams and is about the size of a clenched fist. The medial side of each kidney contains an indented region called the hilum through which pass the renal artery and vein lymphatics nerve supply and ureter which carries the final urine from the kidney to the bladder where it is stored until emptied.

Kidneys are retroperitoneal organs Their function is to maintain electrolyte homeostasis and waste excretion They empty medially into the ureters Ureters course inferiorly into the pelvis and enter the urinary bladder The urine is temporarily stored in the urinary bladder till it is cleared to the exterior through the urethra. The ureter from the upper kidney was joined by that from the lower so that there were only two uteric openings into the bladder. The two kidneys may be joined by their upper and lower poles or even in the middle of the organs.

They cross in front of the great vessels and vertebral column. Anatomy of the Bladder. The bladder is part of your urinary tract.

Its a hollow organ in your lower belly pelvis. Urine is stored in it. This is the liquid waste thats made by the kidneys.

Urine flows away from each kidney through a tube called a ureter. The ureters carry the urine into your bladder.
