Human Circulatory System Functions

The video explains the circulatory system, focusing on the heart's anatomy and the flow of blood. It covers the oxygenation process in the lungs, systemic circulation to the body, and specific blood flow to organs like the liver, kidneys, and gastrointestinal tract. The video concludes with a summary of the circulatory system's function.

What are the two main chambers of the heart?

• Aorta and Vena Cava

• Pulmonary and Systemic

• Left and Right Atrium

• Atria and Ventricles

Which vessel carries deoxygenated blood from the right ventricle to the lungs?

• Superior Vena Cava

• Pulmonary Vein

• Aorta

• Pulmonary Artery

What is the primary function of the left ventricle?

• Pump blood to the lungs

• Pump oxygenated blood to the body

• Filter blood through the liver

• Receive blood from the body

Which artery supplies blood to the arms?

• Hepatic Artery

• Carotid Artery

• Brachial Artery

• Femoral Artery

What is the role of the jugular veins?

• Drain blood from the legs

• Supply blood to the brain

• Drain blood from the head

• Supply blood to the arms

Which organ is primarily responsible for filtering and cleaning the blood?

• Heart

• Liver

• Kidneys

• Lungs

What is the function of the hepatic portal vein?

• Transports blood from the gastrointestinal tract to the liver

• Carries blood from the liver to the kidneys

• Connects the liver to the heart

• Supplies oxygenated blood to the liver

Which artery supplies blood to the legs?

• Carotid Artery

• Femoral Artery

• Brachial Artery

• Hepatic Artery

What happens to blood as it passes through the kidneys?

• It receives nutrients

• It is filtered and cleaned

• It is deoxygenated

• It becomes oxygenated

Why does blood from the gastrointestinal tract go to the liver before returning to the heart?

• To be warmed

• To be cooled

• To be filtered for waste products

• To receive oxygen
