Respiratory and Cardiovascular Health Quiz

Respiratory system primarily deals with gas exchange, not circulation.

Diaphragm aids in breathing by expanding and contracting, facilitating gas exchange.

Asthma is characterized by chronic inflammation of airways, resulting in breathing difficulties.

Emphysema is a condition characterized by damaged air sacs in the lungs, causing breathing difficulty.

Pneumonia refers to inflammation of lung air sacs, often caused by infection.

Pulmonary vein carries oxygenated blood from lungs to heart, opposite to the usual flow of veins.

Hypertension, or high blood pressure, is a significant risk factor for cardiovascular diseases.

Myocardial infarction refers to a heart attack, caused by the interruption of blood flow to the heart.

Resting heart rate for adults typically ranges between 60-80 beats per minute.

Platelets are responsible for blood clotting, aiding in wound healing.

Alveoli primarily exchange oxygen and carbon dioxide during respiration.

SA node initiates the heartbeat by generating electrical impulses.
