Circulation & Lymphatic System Flashcards
What is the primary function of the heart?
Propels blood; maintains blood pressure
What is the primary function of blood vessels?
Distribute blood around the body
What is the primary function of arteries?
Carry blood from the heart to capillaries
What is the primary function of capillaries?
Permit diffusion between blood and interstitial fluids
What is the primary function of veins?
Return blood from capillaries to the heart
What is the primary function of blood?
Transports oxygen, carbon dioxide, and blood cells; delivers nutrients and hormones; removes wastes; assists in temperature regulation and defense against disease
What does the cardiovascular system transport?
Cells and dissolved materials, including nutrients, hormones, wastes, and gases
What is the starting point of blood flow in the pulmonary circuit?
Pulmonary arteries
What happens to blood in the capillaries in the lungs?
It becomes re-oxygenated
What does the right atrium receive blood from?
The systemic circuit
What does the left atrium collect blood from?
The pulmonary circuit
What does the left ventricle do with oxygenated blood?
Pumps it into the systemic circuit
How does de-oxygenated blood re-enter the heart?
It re-enters the right atrium and is then transferred to the right ventricle
What circuit does blood travel to from the right ventricle?
Pulmonary circuit
How does blood return to the right atrium after circulating through the body?
Through the veins of the body
