Understanding Circulatory System Dysfunction Quiz

Arteries carry oxygenated blood away from the heart to the body's tissues and organs.

Capillaries have thin walls, facilitating the exchange of nutrients, oxygen, and waste products between blood and tissues.

Hypoperfusion refers to inadequate blood flow, leading to insufficient oxygen and nutrient delivery to meet the body's demands.

Arrhythmia is an abnormal and rapid heart rhythm that can impair the heart's ability to pump blood effectively.

A blockage or clot within a blood vessel is medically termed a thrombus, potentially causing circulatory issues.

Cool, clammy skin is a common sign of shock, indicating poor circulation and reduced perfusion.

Hypoperfusion leads to inadequate blood flow, resulting in tissue and organ damage due to insufficient oxygen and nutrients.

Platelets play a crucial role in blood clotting, forming clots to prevent excessive bleeding.

Pale skin is a symptom of severe bleeding, indicating decreased blood supply and oxygen to tissues.

Prolonged shock can lead to organ failure due to sustained inadequate blood flow and tissue perfusion.

Direct pressure is applied to wounds in bleeding control to stop blood flow and promote clotting.

The body compensates for blood loss by increasing the heart rate to maintain blood flow and perfusion.

A 'TQ' or tourniquet is used in bleeding control to stop blood flow by constricting the blood vessels.

Tachycardia is a rapid heart rate, often seen as the body's compensatory response to shock or blood loss.

Veins carry deoxygenated blood back to the heart from the body's tissues.

Red blood cells transport oxygen from the lungs to the body's tissues, supporting cellular function.

The circulatory system's primary function is to transport nutrients and oxygen to cells and remove waste products.
