Circulation and Respiration
What happens when the body requires more oxygen?
Respiration and heart rate increase.
The circulatory system is made up of the heart and the
blood vessels.
Respiration, heart rate, and blood pressure are controlled by the _________________________.
brain
What are the three types of circulation? Check all that apply.
coronary systemic pulmonary
Pulmonary arteries carry ____________________ blood away from the heart.
deoxygenated
The oxygen that circulates through the body in the blood is obtained through
respiration.
Why is the myocardium important? Check all that apply.
It is responsible for making the heart pump. It allows the heart to relax and receive blood.
What would happen to a person who has damaged pulmonary veins?
Oxygenated blood would not get back to the heart to be pumped all over the body.
After blood leaves the heart through the aorta, what happens? Check all that apply.
The blood moves through the cells of the body delivering oxygen. The blood moves through progressively smaller blood vessels. The blood removes carbon dioxide and other wastes from the cells.
Who is the most likely to have high blood pressure?
a person with an unhealthy diet and narrow arteries
In the systemic circuit, blood leaves the heart through the
aorta
Oxygenated blood leaves the heart through the
aorta
Which of the following best describes the coronary circuit?
aorta, coronary arteries, heart walls, coronary veins, lungs
During pulmonary circulation, what leaves the heart?
deoxygenated blood
Pulmonary circulation is the movement of blood between the lungs and the __________.
heart
Where does oxygen from the air get absorbed into the blood?
in the alveoli
When heart rate increases, blood pressure ___________________.
increases
The pulmonary circuit circulates blood between the
lungs and heart.
Which of the following can affect the respiratory rate, heart rate, and blood pressure? Check all that apply.
mood lifestyle activity diet
The heart is composed of muscle called
myocardium
What is the name of the muscle the heart is made of?
myocardium
The coronary veins bring _________________________________________ to the right atrium of the heart.
oxygen-poor blood
The coronary arteries bring _________________________________________ to the heart muscle.
oxygen-rich blood
Pulmonary veins carry ____________________ blood to the heart.
oxygenated
Blood pressure is the
pressure of blood against the walls of blood vessels.
What kind of blood vessels carry blood from the heart to the lungs?
pulmonary arteries
What are the pulmonary, systemic, and coronary circuits all involved in? Check all that apply.
removing carbon dioxide from the body regulating the level of oxygen and carbon dioxide in the body moving oxygenated blood around the body maintaining the health of the organs
What does the circulatory system help the body regulate? Check all that apply.
respiratory rate heart rate blood pressure
Which circuit brings oxygenated blood to the rest of the body other than the heart and lungs?
systemic
What is the circulation system responsible for? Check all that apply.
the movement of oxygen through the body the movement of nutrients through the body the removal of carbon dioxide from the body cells
Which of the following are blood vessels of the circulatory system? Check all that apply.
veins capillaries arteries
