How does the blood get oxygen?
The circulatory system pumps blood from the heart to the lungs to get oxygen.

Carbon dioxide from respiration (breathing), other chemical by products from your organs, waste from things you eat and drink.
What is the function of the pulmonary circuit?
To return oxygenated blood to the heart
What is the function of the systemic circuit?
In this circuit, blood with oxygen, nutrients and hormones travels from the heart to the rest of the body.
What is the function of the coronary circuit?
The coronary circuit returns oxygen-poor blood to the heart’s right upper chamber (atrium) to send to the lungs for oxygen.
What are the three main types of blood vessels?
Arteries, veins, capillaries.
What is red blood?
