Understanding the Lymphatic System

What is the primary function of the lymphatic system?

• To produce red blood cells

• To digest food

• To pump oxygenated blood through the body

• To drain fluid from the cardiovascular system

How much lymph do our bodies process daily?

• 5 liters

• 1 liter

• 10 liters

• Upwards of 3 liters

What is lymph?

• Oxygenated blood

• A digestive fluid

• A murky white liquid with proteins and white blood cells

• A type of red blood cell

What happens if your capillaries leak more fluid than your lymphatics can drain?

• You get a fever

• Your heart rate increases

• You experience edema

• Your blood pressure drops

What role do lymph nodes play in the body?

• They regulate body temperature

• They produce oxygen

• They store excess nutrients

• They filter out pathogens from the lymph

What is the main job of the lymphatic system?

• To convert food into energy

• To regulate hormones

• To control body temperature

• To drain fluid from the cardiovascular system

How does lymph move through the body?

• Through a central pump similar to the heart

• By the contraction of smooth muscle around lymphangions

• Via osmosis

• It doesn't move; it's stationary

What is edema?

• A neurological condition

• Swelling due to fluid accumulation in tissues

• A blood disease

• A type of enzyme

What are lymph nodes?

• Bundles of lymphoid tissue that filter pathogens

• Small glands that produce hormones

• Parts of the brain responsible for memory

• A type of white blood cell

What is the significance of the lymphatic system's role in the immune system?

• It produces antibodies

• It supports the immune system by filtering out pathogens

• It creates red blood cells to fight infection

• It regulates body temperature during an infection
