The urinary system mainly consists of a pair of kidneys, ureters, a urinary bladder, and the urethra.
The urinary system forms a major part of the excretory system of the body. It consists of the kidneys, ureter, urinary bladder, and urethra. The urinary system takes blood into the kidneys and filters it to remove the cellular metabolic waste collected from all the organs to form urine. The urine is stored in the urinary bladder until it can be eliminated from the body.
The urinary system can be primarily divided into: the kidneys, the ureters, the urinary bladder, and the urethra. This diagram of the urinary system shows all the organs and their respective positions:
The kidneys are dark, bean-shaped structures measuring 10-12 cm in length and 5-7cm in width. They weigh about 120-170 grams. The anatomy of the kidney can be simplified into 2 major structures:
Outer renal cortex: This part of the kidney houses the glomerulus and the convoluted tubules. The renal capsule surrounds the outer cortex and provides space for the glomerulus's renal artery, veins, and capillaries.
Inner renal medulla: The inner renal medulla is the smooth part within the kidneys that houses the renal pyramids and Loop of Henle. Each kidney has over a million functional units called nephrons which do the filtering.
This kidney diagram labeled gives a simple view of the internal structures of the kidneys:
Here is the diagram of the urinary bladder showing the structures that make up the organ:
1. What are the 7 functions of the urinary system?
The 7 urinary system functions are:
2. What are the 3 main parts of the urinary system?
The 3 main parts of the urinary system are the kidneys, the ureters, and the urinary bladder.
3. What is the functions invloved in the urinary system?
The kidneys filter blood to make urine which is passed through the ureters into the urinary bladder. The urinary bladder holds the urine until it can be excreted through the urethra.
4. Which is the main organ of the urinary system?
The kidneys are the main organs of the urinary system as they do all the filtering of the blood.
5. Where is the kidney located in the body?
The kidneys are located just below the ribcage in the backside of the body.
6. What is urine made of?
Urine is made up of water, all the waste products produced by the body, such as uric acid, urea, and electrolytes such as sodium, potassium, and sulfates.
