Parts of the Heart
This part of the Heart squeezes the blood to the Pulmonary Vein.
Right Ventricle
Carries Oxygen rich blood back to the Heart
Pulmonary Vein
This blood vessel is known as the largest artery of the body.
Aorta
Which blood type is the universal acceptor/recipient?
AB
What is the genetic disorder that blood doesn't clot during bleeding or bruising?
Hemophilia
This muscular wall separates the left and right sides of the Heart.
Septum
This side of the Heart is shaded red in diagrams to show that the blood in this part is high in O2 concentration.
Left
This blood vessel brings CO2 rich blood to the Right Atrium from the body.
Vena Cava
Plasma makes up how much of a human's blood?
55%
Blood Pressure shows 2 different measurements. The Systolic number is found on the top or bottom? It represents pressure when ________________.
Top, when the heart pumps blood in the circulatory system.
This part of the heart sends electrical signals to tell the muscles of the heart when to contract.
Pacemaker
To direct blood to arteries throughout every part of the body.
Smallest blood vessels that are networked around and attached to other tissue and organs throughout the body.
% of blood that contains White Blood Cells and Platelets; and what do the platelets do?
1% ; Clot
Why does the heart-rate climb when you go from sitting to running a 2 mile race?
To transport more Oxygen faster through the circulatory system to the muscles.
These structures make sure that blood does not flow backwards in the heart.
Valves
Which 2 chambers have the thickest walls and why?
Right and Left Ventricles; To squeeze blood for movement through the heart and body.
This type of blood vessel has muscular walls that keep blood under a higher amount of pressure?
Arteries
This blood part is __% water, and contains nutrients, cells, and wastes?
90% ; Plasma
What is it called when a coronary artery gets blocked and muscles around the heart lose oxygen and die.
Heart Attack
This part of the Heart receives blood coming back from the lungs.
Left Atrium
How many sets of valves are in a 4 chambered heart?
4 valves
These types of blood vessels have valves in them to make sure blood doesn't flow backwards due to not having rigid muscular walls and slower blood movement.
A diet heavy in ___________ & ____________ may lead to plaques forming in blood vessels that may later block blood vessels.
Fats / Cholesterol
Why is it important to have so many capillaries surrounding the alveoli in the lungs?
Thinner layers of blood vessel tissue for CO2 and O2 to diffuse in and out of the blood. Also, because they are so small in diameter, it increases the surface area to move more of the gases in and out of the blood.
