Excretation:
They go to the bloodstream, and they are eliminated from the body in the process know as excretation.
The urinary system:
In addition to producing urine
- The kidneys:These two organs are situated on either side of the vertebral column in the lumbar region
- The ureters:Each of these two, narrow tubes leads from one of the kidneys to the bladder. Each ureter is connected to the kidney at the renal pelvis, a funnel-shaped structure within the kidney.
- The cortex:or the outermost layer, has a granular appearance.
- The medulla:which has a striped appearance,is where the renal pyramids are located.
-The blood vessels:both the artery,which enters the kidney,and the vein,which exits,are connected to the concave side of the kidney.
- The bladder:this structure is responsible for storing the urine,which is continuously formed.Its elasticity allows it to vary in volume.When it nears its maximum capacity the urge to urinate occurs.
The two functions of the kidney:
- They help to eliminate waste molecules from the blood (excretion).
- They monitor and maintain the levels of water or mineral salts in the blood, keeping these levels within the healthy ranges homeostasis.
The nephron:each kidney has over a million functional units called nephron
Parts of a nephron:the Bowman's capsule,the collecting duct and the tubule.
The Browan's capsule surrouns a tiny network of capillaries.
The Tubule is in the shape of a handle.The tubules of several nephrona empty into a large tube called a collecting duct.
The collecting ducts move the urine into the renal pelvis.
