What is the function of the right ventricle in the circulatory system?
Pumps blood to the pulmonary trunk
The pulmonary trunk divides into pulmonary arteries for the lungs.
Where does blood go after reaching the pulmonary capillaries?
Returns through pulmonary venules and pulmonary veins
This process involves gas exchange of CO2 and O2.
True or False: In the pulmonary circuit, veins carry oxygen and arteries carry carbon dioxide.
True
This is a unique characteristic of the pulmonary circuit.
What does the systemic circuit include?
All blood vessels except those in the pulmonary circuit
It transports blood from the left ventricle to the right atrium.
In the systemic system, what type of blood do veins carry?
Deoxygenated blood
Arteries carry oxygenated blood in this circuit.
What is the aorta?
The largest artery in the body
It branches to all major body regions and organs.
What does the superior venae cava do?
Collects blood from the head, chest, and arms
It is a large vein that returns deoxygenated blood to the heart.
What is the role of the inferior venae cava?
Collects blood from the lower body regions and organs
It returns deoxygenated blood to the right atrium.
What is the hepatic portal vein?
Connects blood vessels of villi to the liver
It carries nutrient-rich blood to the liver for processing.
What does the hepatic vein do?
Carries blood from the liver to the inferior venae cava
This is part of the systemic circulation.
Fill in the blank: In the pulmonary circuit, _______ carry oxygen and _______ carry carbon dioxide.
veins; arteries
This is the opposite of the systemic circuit.
What major blood vessels are included in the systemic circuit?
Aorta, Superior Venae Cava, Inferior Venae Cava, Hepatic Portal Vein, Hepatic Vein
These vessels are critical for blood circulation.
What blood type does the subclavian artery and vein deal with?
Blood from the arms and upper body
They are important for upper body circulation.
What is the function of the jugular vein?
Drains blood from the head
It is essential for returning deoxygenated blood to the heart.
