Question 1

What is the function of the mitral valve in the heart?

Accepted Answer

Prevents backflow into the left atrium.

Answer

The mitral valve, also known as the bicuspid valve, is located between the left atrium and the left ventricle of the heart. Its primary function is to close during ventricular contraction (systole) to prevent oxygenated blood from flowing backward into the left atrium. This ensures efficient forward flow into the left ventricle and then to the aorta, maintaining proper circulation.

Question 2

Which body system includes the kidneys and bladder?

Accepted Answer

Urinary system

Answer

The urinary system, also known as the renal system, is responsible for filtering blood and creating urine as a waste by-product. It includes the kidneys, which filter waste and excess water from the blood, and the bladder, which stores urine before it is expelled from the body. These organs work together to maintain fluid and electrolyte balance and eliminate metabolic waste.

Question 3

What does the medical prefix 'brady-' mean?

Accepted Answer

Slow

Answer

The medical prefix 'brady-' is derived from Greek and consistently means 'slow.' It is commonly used in medical terminology to describe a condition or symptom characterized by slowness. Examples include 'bradycardia' (slow heart rate) or 'bradypnea' (slow breathing), indicating a rate that is below the normal range.

Question 4

What is the largest organ in the human body?

Accepted Answer

Skin

Answer

The skin is the largest organ in the human body by both surface area and weight, covering approximately 20 square feet in adults. It serves as a vital protective barrier against the environment, regulates body temperature, and prevents water loss. This extensive coverage and multiple functions solidify its status as the largest organ.

Question 5

Which plane divides the body into right and left halves?

Accepted Answer

Sagittal plane

Answer

The sagittal plane is an anatomical plane that divides the body vertically into right and left sections. When this plane passes directly through the midline, dividing the body into equal right and left halves, it is specifically referred to as the midsagittal or median plane. This division is fundamental for describing the location of anatomical structures.
