//Multiple Choice

What is the primary function of the kidneys in the human body? {
    ~Oxygen transport
    =Filtration of blood and removal of waste
    ~Production of hormones
    ~Regulation of body temperature
}

The structural and functional unit of the kidney is called\: {
    ~Alveolus
    =Nephron
    ~Glomerulus
    ~Bronchiole
}

Which of the following is NOT a role of the kidneys? {
    ~Regulation of blood pressure
    ~Maintenance of electrolyte balance
    =Storage of urine
    ~Excretion of metabolic waste
}

The kidneys filter waste from the blood and excrete it as\: {
    ~Sweat
    =Urine
    ~Carbon dioxide
    ~Lymph
}

Which hormone helps the kidneys regulate water balance in the body? {
    ~Insulin
    =Antidiuretic hormone (ADH)
    ~Thyroxine
    ~Glucagon
}

//True or False

Kidneys play a role in maintaining blood pressure. {T}

The urethra connects the kidneys to the bladder. {F}

Filtration of blood in the kidneys occurs in the nephron. {T}

Kidneys can excrete glucose when blood sugar levels are very high. {T}

//Fill in the blanks

The process of filtration in the kidneys occurs in the __________. {
    ~Alveoli
    =Glomerulus
    ~Pancreas
}

The liquid waste filtered by the kidneys is known as __________. {
    ~Blood
    =Urine
    ~Plasma
}

The two kidneys are connected to the urinary bladder by tubes called __________. {
    ~Urethra
    =Ureters
    ~Capillaries
}

Kidneys regulate the pH of the blood by excreting __________ ions. {
    ~Calcium
    =Hydrogen
    ~Sodium
}

The functional unit of the kidney responsible for filtration is the __________. {
    ~Bronchiole
    =Nephron
    ~Capillary
}

//Match the following

Match the following items from Column A with their correct corresponding options from Column B\:
{
=Glomerulus -> Filtration of blood
=Ureters -> Connect kidneys to the urinary bladder
=Nephron -> Functional unit of the kidney
=ADH -> Regulates water reabsorption
=Urine -> Excreted liquid waste
}
