Perfusion Quiz The concept

What is perfusion?

• The process of breathing in and out

• The movement of lymph through lymphatic vessels

• Adequate arterial blood flow through peripheral tissues and to major body organs

• The transfer of nerve impulses across synapses

Answer explanation

Perfusion refers to adequate arterial blood flow through peripheral tissues and major body organs.

What does central perfusion specifically refer to?

• Blood flow to the heart itself

• Blood pumped by the heart to oxygenate major body organs

• Blood flow through the veins back to the heart

• Blood flow through the capillaries in the extremities

Answer explanation

Central perfusion specifically refers to blood pumped by the heart to oxygenate major body organs.

Peripheral perfusion is the blood flow through which areas of the body?

• The central nervous system

• The heart and lungs

• Peripheral tissues

• The digestive tract

Answer explanation

Peripheral perfusion refers to the blood flow through peripheral tissues, not the central nervous system, heart and lungs, or the digestive tract.

What is the primary function of perfusion?

• To remove waste products from the body

• To carry oxygen and nutrients to the tissues and organs

• To regulate body temperature

• To produce hormones

Answer explanation

Perfusion's primary function is to carry oxygen and nutrients to the tissues and organs, ensuring proper functioning and health of the body.

What can occur if there is not enough perfusion?

• Increased energy levels

• Faster healing of tissues

• Pain due to ischemia

• Improved oxygenation

Answer explanation

Not enough perfusion can lead to pain due to ischemia, which is the inadequate blood supply to tissues causing oxygen deprivation and subsequent pain.

What is a possible consequence of prolonged inadequate perfusion?

• Tissue regeneration

• Tissue death (Infarction)

• Hypertension

• Vasodilation

Answer explanation

Prolonged inadequate perfusion can lead to tissue death (Infarction) due to the lack of oxygen and nutrients reaching the cells, causing irreversible damage.

What does the "pump" represent in the human body according to the learning material?

• Lungs

• Heart

• Kidneys

• Brain

Answer explanation

The 'pump' in the human body represents the Heart according to the learning material.

What are the "hoses" in the human body as per the learning material?

• Veins

• Bones

• Arteries

• Muscles

Answer explanation

The 'hoses' in the human body referred to in the learning material are arteries, which carry oxygen-rich blood away from the heart to the rest of the body.

According to the learning material, what is the "fluid" in the human body?

• Blood with oxygen

• Lymph

• Blood with oxygen

• Water

Answer explanation

The correct fluid in the human body according to the learning material is blood with oxygen.

Why would the heart not work?

• Infection

• Electrical problem

• Mechanical problem

• Dehydration

Answer explanation

The heart may not work due to an electrical problem or a mechanical problem, which can disrupt its normal functioning.
