Blood Vessels Flashcards
(14 cards)
What are arteries responsible for?
Carrying oxygenated blood away from the heart
Arteries are made of thick and elastic tissue.
What is the primary function of veins?
Bringing deoxygenated blood back to the heart
Veins have thin walls and operate under low pressure.
What distinguishes pulmonary veins from other veins?
They carry oxygenated blood
All other veins carry deoxygenated blood.
What structural feature do veins possess?
Valves
Valves help prevent backflow of blood.
What is the role of capillaries in the circulatory system?
Form a network throughout the body
Capillaries connect arteries and veins.
How would you describe the walls of capillaries?
Very narrow
This allows for efficient gas and nutrient exchange.
What type of blood do arteries typically carry?
Oxygenated blood
Except for the pulmonary artery, which carries deoxygenated blood.
What is the pressure condition of blood in veins?
Low pressure
This is due to the distance from the heart and the structure of veins.
Fill in the blank: Veins carry _______ blood from the body back to the heart.
deoxygenated
True or False: Arteries have valves to prevent backflow.
False
Only veins have valves.
What do capillaries lack?
Valves
What is noted about the selfsurtace?
It is very deeper than tissues and organs
The selfsurtace refers to a surface that is deeper compared to the tissues and organs.
How do smaller items relate to larger ones?
Smaller items become venule and arterioles when they are divided
What is mentioned about blood flow?
Blood flows comparatively with owocpresun
‘Owocpresun’ likely refers to a specific pressure or condition affecting blood flow.
