Structures
The pump of the circulatory system
Heart
What does the circulatory system do?
Delivery/transport of oxygen, nutrients, etc as well as carbon dioxide and other waste products.
The largest artery
Aorta
How many chambers does the heart have?
Four
What determines your blood type?
Parents
Genes
These tubes have valves to prevent backflow
Veins
What role do arteries play?
They are hollow tubes that take oxygenated blood away from the heart.
This vessel is the largest in the anterior thigh
Femoral artery/vein
Pulmonary artery
Force the propels blood throughout the body
Why do arteries have to be thicker than veins or capillaries?
To handle the pressure
What do white blood cells do?
Fight infection, body's defense
The vessel that would come next if blood was flowing away from the heart. Subclavian, Axillary...
Brachial artery
This heart chamber has the thickest walls around it because it ejects blood to the body
Left ventricle
This is responsible for the lub dub sound your heart makes
Valves closing
Either of the two large blood vessels that will eventually dump deoxygenated blood into the right atrium
Vena cava
What are the role of capillaries?
The exchange site of carbon dioxide and oxygen, as well as nutrients and waste products
The large vein in the neck that we have labeled
Jugular vein
This is the structure between the right atrium and right ventricle
A/V valve
The role of red blood cells
Carry oxygen to the body
Carry carbon dioxide to the lungs
These are cells are responsible for clot formation
Platelets
The function of the SA node
the heart's natural pacemaker
Blood has traveled to the pinky side of the forearm. Oxygen has been traded for carbon dioxide at the capillary. Now its time to go back to the heart. This is the vessel to start that journey back.
Ulnar vein
What step is after the right ventricle?
Pulmonary valve
2 ways that the circulatory system connects to the muscular system
Heart is a pump-- cardiac muscle
Blood vessels are smooth muscle
Circulatory system delivers oxygen and nutrients/removes waste products from muscles
