The largest ARTERY in our body:
Pulmonary Artery
Inferior Vena Cava
Aorta
Septum
Blood carries (choose the BEST option):
Nutrients
Oxygen
Carbon Dioxide
All of the above
The correct order of deoxygenated blood entering the heart and traveling to the lungs:
Aorta > right ventricle> right atrium > left atrium > left ventricle > lungs
Vena cava > right atrium > right ventricle> pulmonary artery > lungs
Vena Cava > left atrium > left ventricle > pulmonary vein > lungs
Pulmonary vein > left atrium > left ventricle > aorta> body
The correct order of oxygenated blood entering the heart and going to the body:
Pulmonary vein > left atrium > left ventricle > aorta> body
Pulmonary artery > right atrium > right ventricle > aorta > body
Aorta > left ventricle > left atrium > body
Pulmonary vein > left ventricle > right atrium > pulmonary artery > body
Which is NOT a function of the circulatory system?
deliver O2 and nutrients to cells
remove CO2 and wastes from cells
break down carbohydrates into glucose
transport nutrients to tissue cells
transport wastes for excretion
Which of the following best describes the exchange of gases between capillaries and body cells?
Carbon dioxide and oxygen enter the body.
Carbon dioxide and oxygen switch places.
Carbon dioxide and oxygen leave the body.
When gases travel around the room.
The chamber of the heart that receives oxygen poor blood from the other parts of the body
Right Atrium
Left Ventricle
Right Ventricle
Left Atrium
Blood coming from the left leg would enter which chamber of the heart?
What are the two functions of the circulatory system?
oxygen from lungs --> heart --> body
carbon dioxide from body --> heart --> lungs
oxygen from body --> heart --> lungs
carbon dioxide from lungs --> heart --> body
Two ways your body can lose heat
Evaporation of sweat
Shivering
Body hairs becoming erect
Vasodilation
These send the nerve signal to the ventricles to contract:
Purkinje fibres
hypothalamus
AV valve
chordae tendinae
What is diastole?
ventricles filling
ventricles pumping
atria filling
a measure of heart rate
When the ventricles empty, this is known as:
diastole
systole
systemic
thump thump
What is cardiac output? Check all that apply!
how much blood is pumped by the heart each minute
stroke volume (mL/beat) x heart rate (beats/min)
the same as a heart attack
approximately 500L/min in an average 70 kg human
Which person would have stronger heart?
Joe - high stroke volume, low heart rate
Bob - low stroke rate, high heart rate
Ms. Matthews - heartless
Which process in the human body releases heat?
photosynthesis
cellular respiration
heart filling
vasoconstriction
There is another system of vessels in the body that circulates fluid important for the immune system in a way that is similar to veins. What is it called?
The digestive system
The respiratory system
The lymphatic system
The muscles
In a stressful situation, which type of nervous system would be stimulated and what's the result?
parasympathetic - decrease heart rate
sympathetic - increase heart rate
What causes the classic lub dub heart sounds?
filling and emptying of the chambers in the heart
blood moving through arteries
blood leaving the aorta
blood moving through the capillaries
The part of the circulatory system that delivers blood to the body's cells is called:
pulmonary
cardiac
systemic
ventricular
Which chamber of the heart has the thickest, strongest muscle for pumping oxygenated blood out to the entire body?
left atrium
right atrium
left ventricle
right ventricle
How are you feeling about the circulatory system?
Like an elite athlete with a high stroke volume and a heart that barely needs to pump - I'm amazing!
Like a heart divided into two sides - I'm working hard and efficiently!
Like a frog heart with only 3 chambers - oxygenated and deoxygenated blood mixing isn't the best but not the worst! Review time.
Like a vein with a leaky valve ... could be better! Need to study!
What is true about the carotid artery? Check all that apply.
It takes blood from the aorta to the head
It is in the neck and can be used to measure heart rate
It takes blood from the head back to the heart
You will need it to carry oxygenated blood to your brain during your exam!
A blockage in this artery would likely not be serious
Capillary networks facilitate the exchange of gases and nutrients in which structures? Check all that apply
around the villi in the small intestine
around the alveoli in the lungs
around the nephron tubules in the kidney
around the stomach lining
Which chamber of the heart fills with oxygenated blood from the lungs?
left atrium
pulmonary veins
left ventricle
right atrium
right ventricle
Which chamber of the heart fills with deoxygenated blood from the body?
left atrium
pulmonary veins
left ventricle
right atrium
right ventricle
What is the largest artery in the human body?
aorta
coronary artery
pulmonary arteries
superior vena cava
On the first heart beat (diastole), both aorta contract to push blood into the ventricles. On the second heart beat (systole), both ventricles contract to pump blood into the pulmonary and systemic circuits. Check all statements that are true about the pumping by the ventricles.
the left ventricle pumps oxygen poor blood to the lungs
the left ventricle pumps oxygen poor blood to the body
the right ventricle pumps oxygen poor blood to the lungs
the left ventricle pumps oxygen rich blood to the body
Both ventricles cannot contract at the same time.
