What is one function of blood? Be specific. 

Transportation - Oxygen, carbon dioxide, nutrients

Regulation - pH of fluids, body temp, water content 

Protection - blood clotting, WBCs against disease 

100

What are the 2 upper chambers of the heart?

Atria 
100

Calculate the cardiac output of a person with a heart rate of 80 beats/min and a strove volume of 65 mL.  - You need the correct units! 

5200 mL/min or 5.2 L/min
100
What is one difference between an artery and a vein?
Arteries take blood away from the heart, veins bring blood back to the heart 

Veins have a wider lumen

Veins have thinner middle and inner wall layers

100
What is one of the common arteries used to check pulse?
Carotid 

Radial 

Femoral 

Popliteal 

200
This ABO blood type is considered the universal donor
O
200
Blood coming from below the heart returns back to the heart through this vein 
Inferior vena cava 
200
The circulation of blood through the heart and lungs is referred to as ___________ circulation. 
Pulmonary 
200
What type of artery is the aorta?
Elastic artery 
200

This blood vessel drains blood from the kidneys

Renal vein
300

What ABO blood type(s) have A antigens on the surface of the RBCs?

 A & AB
300
What is the main function of valves?
Prevent blood from flowing backwards 
300

This is the route for action potentials throughout the heart muscle

Conduction system 
300
What is one way the pressure is generated in order to bring blood in veins back to the heart?
- Contractions of the heart 

- Skeletal muscle pump 

- Respiratory pump 

300

This refers to a slow resting heart rate or pulse rate under 50 beats/min

Bradycardia
400

Describe (don't just name) one mechanism of hemostasis 

Vascular spasm - contraction of smooth muscle is blood vessel walls 

Platelet plug - mass of platelets that plug hole in wall

Blood clot - blood turns to gel to block damaged wall 

400
What type of valves are the tricuspid and bicuspid (mitral) valves?
Atrioventricular (AV) valves
400
During this phase of the cardiac cycle, the atria contract, pumping blood into the ventricles. 

Atrial systole 

400

What is one example of an elastic artery and one example of a muscular artery?

Elastic - aorta and brachiocephalic, common carotid, pulmonary and common iliac arteries

Muscular - brachial artery, radial artery

400
Systolic pressure occurs while the heart is _________ while diastolic pressure occurs while the heart is _________.
contracting, filling (relaxing)
500
If a person receives type AB blood via transfusion but is type A, what will happen to their RBCs?
Hemolysis 
500
What are the three structures, including valves, that blood flows through before reaching the aorta?
Bicuspid (mitral) valve -> left ventricle ->aortic valve 
500

What does the QRS complex of an electrocardiogram represent? 

Ventricular depolarization - as the cardiac action potential travels through the ventricles. 

500

What is the difference between vasoconstriction and vasodilation?

Vasoconstriction - narrowing of the lumen

Vasodilation - widening of the lumen

500
Which arteries supply blood to the brain, face and neck?

Which veins drain blood from the brain, face and neck?

Carotid arteries

Jugular veins
