veins
In the circulatory system, pulmonary arteries carry blood ______ the heart
away from
All arteries in the body carry oxygenated blood.
False
Veins always carry oxygenated blood.
False
Pulmonary arteries and veins have the same function as other arteries and veins in the body.
False
Arteries and veins can be identified based on the direction of blood flow alone.
False
The rule that arteries carry oxygenated blood and veins carry deoxygenated blood is universal and applies to all blood vessels in the body.
False
Veins always carry deoxygenated blood, while arteries always carry oxygenated blood.
False
All arteries in the body carry blood away from the heart.
True
The function of pulmonary arteries is different from that of other arteries in the body.
False
Veins always carry blood toward the heart, but they may contain oxygenated blood.
False
Both arteries and veins can contain exceptions to the general rule of blood oxygenation.
True
Which artery carries blood from the heart to the body?
Aorta
What is the primary function of the pulmonary arteries?
To carry deoxygenated blood from the heart to the lungs
Which vessel carries deoxygenated blood from the body to the heart?
Cranial vena cava
What is the exception to the oxygenation rule in the circulatory system?
Pulmonary arteries and veins
Which vessel carries oxygenated blood from the lungs to the heart?
Pulmonary vein
What is the primary function of the aorta?
To carry blood from the heart to the body
What type of blood do pulmonary arteries carry?
Deoxygenated blood
What carries oxygenated blood from the lungs to the heart?
Pulmonary veins
What is the common direction of blood flow in veins?
Toward the heart
What is unique about the pulmonary arteries and veins compared to other arteries and veins?
They are exceptions to the oxygenation rule
The pulmonary arteries carry oxygenated blood from the heart to the lungs.
False
The cranial and caudal vena cavae are arteries that carry blood from the heart to the body.
False
The aorta is a vein that carries deoxygenated blood from the body to the heart.
False
All arteries in the body carry oxygenated blood, except for the pulmonary arteries.
True
The pulmonary veins are the only veins that carry oxygenated blood.
True
What is the primary function of the pulmonary veins in the circulatory system?
to carry oxygenated blood from the lungs to the heart
What is the difference between the cranial and caudal vena cavae and the aorta?
The cranial and caudal vena cavae carry blood from the body to the heart, while the aorta carries blood from the heart to the body.
Why are pulmonary arteries and veins exceptions to the rule about arteries and veins?
because they carry opposite types of blood, with pulmonary arteries carrying deoxygenated blood and pulmonary veins carrying oxygenated blood
What type of blood do veins usually carry, and what is the exception?
Veins usually carry deoxygenated blood, but the exception is pulmonary veins, which carry oxygenated blood.
What is the direction of blood flow in the aorta?
away from the heart
Match the following blood vessels with their functions:
Aorta = Carries blood from the heart to the body Pulmonary arteries = Carries deoxygenated blood from the heart to the lungs Cranial and caudal vena cavae = Carries blood from the body to the heart Pulmonary veins = Carries oxygenated blood from the lungs to the heart
Match the following blood vessels with the parts of the heart they connect to:
Aorta = Left ventricle Pulmonary arteries = Right ventricle Cranial and caudal vena cavae = Right atrium Pulmonary veins = Left atrium
Match the following blood vessels with the type of blood they carry:
Aorta = Oxygenated blood Pulmonary arteries = Deoxygenated blood Cranial and caudal vena cavae = Deoxygenated blood Pulmonary veins = Oxygenated blood
Match the following blood vessels with their directions of blood flow:
Aorta = Away from the heart Pulmonary arteries = Away from the heart Cranial and caudal vena cavae = Towards the heart Pulmonary veins = Towards the heart
Match the following blood vessels with their exceptions to the oxygenation rule:
Pulmonary arteries = Carries deoxygenated blood Pulmonary veins = Carries oxygenated blood Aorta = No exception Cranial and caudal vena cavae = No exception
Learn about the cord-like tendons that maintain the position of the valve leaflets in the AV valves during ventricular contraction. Understand how they prevent the valves from opening backwards into the atrium and their connection to the papillary muscles.
