Question 1

A person frequently experiences heartburn (azia) after meals due to excessive production of hydrochloric acid in the stomach. A doctor explains the digestive process and recommends dietary adjustments along with an antacid medication when needed. What is the primary role of gastric juice in the human stomach, and how do antacids relieve heartburn?

Gastric juice absorbs water and vitamins directly into the bloodstream; antacids accelerate peristaltic contractions of the stomach walls. Gastric juice contains hydrochloric acid and enzymes like pepsin to break down proteins; antacids are basic substances that neutralize excess acid, raising stomach pH to a comfortable level. Gastric juice emulsifies dietary fats into microscopic droplets; antacids stimulate the gallbladder to release additional bile. Gastric juice breaks down carbohydrates into glucose; antacids coat the small intestine to block nutrient absorption.

Correct Answer:

Gastric juice contains hydrochloric acid and enzymes like pepsin to break down proteins; antacids are basic substances that neutralize excess acid, raising stomach pH to a comfortable level.

Question 2

During physical exercise, a person's breathing rate increases substantially to supply working muscles with oxygen and eliminate carbon dioxide. In which microscopic structures of the human respiratory system does this crucial exchange of respiratory gases (hematose) take place?

In the nasal cavities and pharynx Along the cartilage rings of the trachea Inside the main bronchi of the upper chest In the pulmonary alveoli surrounded by blood capillaries

Correct Answer:

In the pulmonary alveoli surrounded by blood capillaries

Question 3

The human cardiovascular system is a closed double-circulation network driven by the heart. Which chamber of the heart receives oxygenated blood returning from the lungs, and which chamber pumps this oxygen-rich blood through the aorta to the rest of the body?

The left atrium receives oxygenated blood from the pulmonary veins, and the left ventricle pumps it out through the aorta. The right atrium receives oxygenated blood from the vena cava, and the right ventricle pumps it to the aorta. The left ventricle receives oxygenated blood directly from the trachea, and the right atrium pumps it to systemic tissues. The right ventricle receives oxygenated blood from the lungs, and the left atrium pumps it to the brain.

Correct Answer:

The left atrium receives oxygenated blood from the pulmonary veins, and the left ventricle pumps it out through the aorta.

Question 4

Every summer, Brazilian municipal public health agencies launch campaigns to prevent outbreaks of dengue, chikungunya, and Zika. Which practical preventive measure is most effective in stopping the reproduction of the mosquito vector (Aedes aegypti) in residential neighborhoods?

Boiling tap water before drinking and washing fresh vegetables Installing carbon monoxide detectors in indoor living rooms Eliminating standing water in plant saucers, discarded tires, open water tanks, and clogged gutters Applying antibiotic ointments to small skin cuts and scrapes

Correct Answer:

Eliminating standing water in plant saucers, discarded tires, open water tanks, and clogged gutters

Question 5

A rural worker is bitten by a venomous snake (jararaca) and immediately transported to an emergency clinic. The physician administers a specific antivenom serum (soro antiofídico) rather than a vaccine. What is the key functional difference between a therapeutic serum and a preventive vaccine?

A serum contains ready-made antibodies that provide immediate, passive immunity to neutralize toxins, whereas a vaccine introduces antigens to stimulate the body to produce its own antibodies and immunological memory over time. A serum stimulates long-term immunological memory cells, whereas a vaccine provides temporary, instant pain relief. A vaccine is made exclusively of living bacteria to treat active poisonings, while a serum contains dead plant extracts. A serum prevents future infections over decades, while a vaccine only acts within the first thirty minutes of an emergency.

Correct Answer:
