The Human Body

Question 1:

Fill in the blank: Blood pressure is measured using two numbers: systolic and ____.

Diastolic

  • Systolic blood pressure (top number) measures artery pressure when the heart contracts, while diastolic (bottom number) measures pressure when the heart rests between beats.

Question 2:

Name the disease that is caused by excessive uric acid forming needle-like crystals in the body's joints, resulting in severe pain.

Gout

  • Gout is the most common type of inflammatory arthritis. Gout is highly treatable with lifestyle changes such as diet and weight loss and medications. Without treatment, it can lead to chronic joint destruction and kidney issues.

Question 3:

Nephrons are microscopic structures in what organ of the human body?

Kidney

  • Nephrons filter blood, regulate blood pressure and volume, and remove waste from the body. A healthy adult has 1 to 1.5 million nephrons in each kidney.

Question 4:

What part of the body is controlled by the hypoglossal nerve?

Tongue

  • The nerve controls the movements required for speech and swallowing, including sticking out the tongue and moving it from side to side. The Greek anatomist Herophilos first described the nerve in the third century BC.

Question 5:

Rods and cones are specialized cells in this light-sensitive part of the human eye.

Retina

  • Rods are photoreceptors that are highly sensitive to light; they are vital for night vision and peripheral vision. Unlike cones, rods do not distinguish colors. There are three types of cone photoreceptors, each sensitive to different wavelengths of light: long (red), medium (green), and short (blue).
