400

Control the flow of blood through the heart by opening and closing during contractions

Valves

500

Blood just entered the right atrium. Trace it through the heart and back out into the body.  

Right ventricle - pulmonary artery - lungs - left atrium - left ventricle - aorta - body

Blood Vessels

100

This blood vessel carries oxygenated blood away from the heart. 

Artery

200

This blood vessel carries deoxygenated blood away from the body. 

Vein

300

These are the blood vessels where oxygen and carbon dioxide exit the blood and enter the tissue of the body. 

Capillaries

400

Sends blood from the heart to the lungs and back. One of two parts of the circulatory system

Pulmonary circulation

500

Part of the circulatory system that sends blood to the rest of the body and back to the heart.

Systemic circulation

Named parts of the system

100

Biggest artery, carries oxygenated blood to the rest of the arteries

Aorta

200

Biggest vein, carries deoxygenated blood to the heart. Has two parts.

Vena Cave (superior and inferior)

300

The three major blood vessels are located when first entering the heart from the body, when entering the lungs from the heart, and when exiting the heart to the body. True or false?

True. The vena cava enters the heart, the pulmonary artery enters the lungs, and the aorta exits the heart. 

400

What are the names of the chambers of the heart and where are they located?

Right atrium - top right

Right ventricle - lower right

Left atrium - top left

Left ventricle - lower left

500

This giant artery takes blood from heart to the lungs to pick up oxygen.

Pulmonary artery

Interaction with lungs

100

These two things are exchanged in the lungs during circulation

oxygen and carbon dioxide

200

The lungs and the heart work together to circulate blood throughout the body. This is why we also call the circulatory system the _____________

Cardiovascular system

300

This makes the blood appear reddish 

Oxygen (hem)

400

The tiny sacs in your lungs that hold oxygen are called

alveoli 

500

Blood enters the lungs exactly twice during one full cycle through the body. True or False?

False, the blood only enters the lungs once to pick up oxygen and drop off carbon dioxide during one full circuit through the body.

one

200

These blood vessels connect every artery and vein and blood ________________ carbon dioxide and ____________ oxygen

collects, drops off

300

Blood that does not contain oxygen is called

400

Blood is make up of these three parts

Red blood cells, white blood cells, platelets
