What are three functions of blood?

Transport; regulation; protection 

100

What instrument measures vital capacity?

Spirometer

100

What is the major function of the respiratory system?

Gas exchange (COand O2)

100

This increases to about 25 litres during exercise

cardiac output

100

What is the body's largest blood vessel that transports blood from body back to the heart?

Vena Cava 

200

What is the difference between the Artery & the Vein?

The artery carries blood away from the heart and the Vein carries blood back to the heart.

200

Which is inferior: atria (atriums) or ventricles?

Ventricles.

200

We need oxygen in our cells to complete: 

a) photosynthesis 

OR

b) cellular respiration 

B) cellular respiration 

200

Identify 5 acute responses to the Cardiovascular system from Physical Activity.

Increased stroke volume, Increased cardiac output, Increased blood pressure, increased blood flow redistribution, Increased A-VO2.

200

Which chamber of the heart receives oxygenated blood from the lungs?

Left atrium 

300

Define Vasodilation & Vasoconstriction

Vasodilation: A process whereby blood vessels increase their diameter causing an increase in blood flow. 


Vasoconstriction: A process whereby blood vessels narrow or constrict, causing a decrease in blood flow.

300

True or false:

Pulmonary veins are found on the left side of the heart.

True.

Pulmonary veins are on the left and pulmonary arterys are on the right. 

300

Which lung has two lobes? Which has three lobes?

left; right

300

This is the equation for cardiac output

Cardiac Output= stroke volume x HR

300

What is the left ventricle responsible for?

Sending the oxygenated blood out to the body 

400

Blood cells contain hemoglobin. What does it do?

Hemoglobin: protein that binds and carries oxygen 

400

Arteries carry blood AWAY from the heart and veins carry blood TOWARDS the heart. True or false?

True!

400

Describe the pathway air takes to enter our body all the way to the alveoli.

nasal cavity - pharynx - larynx - trachea - bronchi - bronchioles - alveoli

400

Baroreceptors play a crucial role in controlling

Blood pressure

400

What do the tricuspid and bicuspid valves control?

Stops blood from flowing back into the atria (blood moving the incorrect way)
500

Define Stroke Volume.

The amount of blood ejected from the left ventricle with each heartbeat (contraction) of the heart.

500

What is the primary pacemaker of the heart?

Sinoatrial node

500

What is the relationship between pressure and volume changes that causes air to flow in and out of the lungs?

When our diaphragm contracts, it allows more volume to enter our lungs. This causes a decrease in pressure that allows air to enter our lungs since it moves from high to low pressure. 

500

They detect an increase in carbon dioxide

chemoreceptors 

500

Anticipatory Rise is caused by an increase in activity from the

Sympathetic nervous system.
