$\huge\tt{\underline{\underline\color{red}{Answer}}}$

1) Urinary bladder

$\rm\green{1) \: what \: is \: a \: urinary \: bladder}$

• The urinary bladder is a temporary storage reservoir for urine. It is located in the pelvic cavity, posterior to the symphysis pubis, and below the parietal peritoneum. The size and shape of the urinary bladder varies with the amount of urine it contains and with the pressure it receives from surrounding organs.

2) Kidney

$\rm\pink{2) \: what \: is \: a \: kidney}$

• The kidneys are two bean-shaped organs, each about the size of a fist. They are located just below the rib cage, one on each side of your spine. Healthy kidneys filter about a half cup of blood every minute, removing wastes and extra water to make urine.

3) 1-1.8 liters

4) Renal artery

$\rm\blue{4) \: what \: is \: renal \: artery}$

• Renal artery stenosis is the narrowing of one or more arteries that carry blood to your kidneys (renal arteries).

• Renal artery stenosis is the narrowing of one or more arteries that carry blood to your kidneys (renal arteries).Narrowing of the arteries prevents normal amounts of oxygen-rich blood from reaching your kidneys. Your kidneys need adequate blood flow to help filter waste products and remove excess fluids. Reduced blood flow to your kidneys may injure kidney tissue and increase blood pressure throughout your body.

5) Nephrons
