Total questions: 15
Worksheet time: 8mins
What is the primary function of arteries in the circulatory system?
To carry blood away from the heart
To carry blood towards the heart
To exchange gases and nutrients
To store blood
Which structural feature of arteries helps them withstand high pressure?
Thin walls
Thick muscular walls
Valves
Large lumen
What is the main function of arterioles in the circulatory system?
To act as a reservoir for blood
To regulate blood flow to capillaries
To exchange gases and nutrients
To return blood to the heart
How do veins differ structurally from arteries?
Veins have thicker walls
Veins have valves
Veins have a smaller lumen
Veins carry oxygenated blood
What is the primary role of capillaries in the circulatory system?
To transport blood at high pressure
To exchange gases, nutrients, and waste products
To store blood
To regulate blood pressure
Why are capillary walls only one cell thick?
To provide structural support
To allow rapid diffusion of substances
To prevent blood loss
To increase blood pressure
What is the significance of capillary beds in the circulatory system?
They increase blood pressure
They provide a large surface area for exchange
They store oxygen
They transport hormones
What is tissue fluid, and how is it formed?
A fluid that carries oxygen, formed by the liver
A fluid that surrounds cells, formed by filtration from capillaries
A fluid that transports hormones, formed by the kidneys
A fluid that stores nutrients, formed by the pancreas
How does tissue fluid return to the circulatory system?
Through the lymphatic system
Directly into veins
Through the digestive system
By evaporation
What role do valves in veins play in the circulatory system?
They increase blood pressure
They prevent backflow of blood
They regulate heart rate
They store blood
Which of the following best describes the lumen of a vein compared to an artery?
Narrower
Wider
The same size
Non-existent
What is the primary function of the smooth muscle in the walls of arterioles?
To pump blood
To regulate the diameter of the arterioles
To store nutrients
To produce red blood cells
Which component of blood is primarily responsible for the formation of tissue fluid?
Red blood cells
Plasma
White blood cells
Platelets
What is the main difference between blood plasma and tissue fluid?
Tissue fluid contains more red blood cells
Tissue fluid contains fewer proteins
Tissue fluid contains more oxygen
Tissue fluid contains more carbon dioxide
What is the primary function of the lymphatic system in relation to tissue fluid?
To produce red blood cells
To transport oxygen
To return excess tissue fluid to the bloodstream
To regulate blood pressure
