The right kidney is also placed asymmetrically slightly below the left kidney because of the position of the liver in the right side of the body. Each kidney has a concave and a convex border. The concave border has the hilum, where the blood vessels enter and leave the kidney]]> 2020-12-04 22:51:32 UTC https://padlet.com/ehsanulhaque360/fnqjk742wtiynm8r/wish/989467524 ehsanulhaque360 https://padlet.com/ehsanulhaque360/fnqjk742wtiynm8r/wish/989468516 They are 25-30cm long tubes that exit the kidney through the hilum and run down into the urinary bladder. The walls of the ureters have smooth muscles that help propel the urine forward from the kidneys into the urinary bladder. Sometimes a kidney stone from the kidneys may get stuck between the ureters and block the flow of urine. This also causes a sharp cramp or pain known as renal colic in back side or the lower abdomen.]]> 2020-12-04 22:52:10 UTC https://padlet.com/ehsanulhaque360/fnqjk742wtiynm8r/wish/989468516 santarakhalil https://padlet.com/ehsanulhaque360/fnqjk742wtiynm8r/wish/989470635 It is a hollow organ present in the pelvis. The wall is muscular and has a stretchy structure. A typical bladder can hold between 300 to 500 milliliters of urine before the need to urinate. The urine enters the bladders through the two ureters and exits through the urethra. The bladder has two parts: the body and the neck. The neck makes sure that you don't leak urine all the time because of its smooth muscles which remains contracted, and keeps the opening of the bladder closed. Whenever we have to urinate, the smooth muscles relax the neck of the bladder and allows the urine to pass to the urethra. The smooth muscles is called a sphincter. ]]> 2020-12-04 22:53:51 UTC https://padlet.com/ehsanulhaque360/fnqjk742wtiynm8r/wish/989470635 ehsanulhaque360 https://padlet.com/ehsanulhaque360/fnqjk742wtiynm8r/wish/989484138 Performs the vital function of filtering the blood and removing excessive and unnecessary materials from the body. This helps maintain an internal homeostasis and prevent damage to the body. In a nutshell, the term refers to the urinary system.]]> 2020-12-04 23:04:40 UTC https://padlet.com/ehsanulhaque360/fnqjk742wtiynm8r/wish/989484138 ehsanulhaque360 https://padlet.com/ehsanulhaque360/fnqjk742wtiynm8r/wish/989485809 1.

The renal cortex is the outer region of the kidney, while the renal medulla consists of 12-15 cone-shaped structures known as the medullary pyramids. The blood enters the kidney through the renal artery, which branches off to the cortex area and divide up into smaller branches called capillaries. This is also where there are the most nephrons: the main structure that filters the blood known as the Bowman's capsule. Water and waste metabolic products filtered by nephrons enters the medulla of the kidney through collecting ducts. These ducts then drain the waste products and water into the central part of the kidney known as the renal calyx. They receive the urine from each of the medullary pyramids and drains them to the ureter. ]]> 2020-12-06 06:19:36 UTC https://padlet.com/ehsanulhaque360/fnqjk742wtiynm8r/wish/990989020 ehsanulhaque360 https://padlet.com/ehsanulhaque360/fnqjk742wtiynm8r/wish/991150958 Urethra is another hollow tube-like structure that help propel urine out of the body. It is longer in men than females, as it needs to traverse the length of the male penis. For the same reason, it differs in size from men to women. It has a length of about 4cm in females and a length of about 20cm in men. This is why women have more urinary tract infections than men. ]]> 2020-12-06 08:23:28 UTC https://padlet.com/ehsanulhaque360/fnqjk742wtiynm8r/wish/991150958
