Blood Vessel 1
3 categories of blood vessels
veins, arteries and capillaries
Which type of blood vessel has valves inside?
Vein
How many chambers are in the human heart?
4
What does blood composed of?
rbc, wbc, plasma, platelets
They contain hemoglobin, which carries oxygen from your lungs to your body and brings carbon dioxide back.
RBC
They are the smallest vessels where the exchange of oxygen, nutrients, and waste occurs between blood and tissues
Capillaries
Usually, (with the exception of veins leading from the lungs) the blood flowing in veins is rich or poor in oxygen?
poor
The __________ side of the heart delivers blood to all parts the body except the lungs.
left
This is the throbbing of your arteries as blood moves through them. You can use this to measure your heart rate, the number of times your heart beats in one minute. A normal heart rate for a person at rest is 60 to 100 beats per minute.
pulse
Part of the immune system, these cells fight infection and disease.
WBC
These blood vessels carry deoxygenated blood from the right ventricle to the lungs.
The pulmonary arteries
Which side of the heart manages the flow of deoxygenated blood?
The right side
What kind of blood does pulmonary artery carry?
Deoxygenated blood to the lung
What measures the electrical activity of the heart, and it is used to diagnose problems with the electrical functioning of the heart.
electrocardiogram, or ECG
Which type of blood vessel has a 'pulse'?
artery
What is the artery carrying oxygenated blood away from the heart to the body
Aorta
From which chamber of the heart does blood leave to go to the lungs?
right ventricle
What are the two types of circulation in the body?(think about body & lungs)
Pulmonary circulation (to the lungs) and Systemic circulation (to the rest of the body).
Cardiac Arrest
These blood vessels bring oxygenated blood from the lungs into the left atrium.
The pulmonary veins
The large veins that return blood to the heart.
Superior and Inferior vena cava
The primary job of the pulmonary veins/arteries is to
oxygenate blood
Which chamber of the heart has the thickest walls and why?
The left ventricle, because it must pump blood to the entire body at high pressure.
Why do veins have valves, while arteries do not?
Veins operate under lower pressure and need valves to prevent blood from flowing backward, aided by skeletal muscle movement.
This diagnostic test tests the heart's function when it is under stress, such as during exercise. In a stress test, you will have to walk on a treadmill while I measure your heart's function with an ECG.
