What are Antagonistic muscle pairs
Two muscles that work together to create a movement
What’s the name for contracting muscle
Agonist
What’s the name of the relaxing muscle
Antagonist
What Are the four antagonistic muscle pairs
Bicep and tricep
Hamstring and quadricep
Gluteus maximus and hip flexor
Tibialis anterior and gastrocnemius
What’s the septum
Separates the right-hand and left-hand side of the heart
What’s the name of the valve on the left-hand side of the heart
Bicuspid valve
What is the valve in the right side of the heart
Tricuspid valve
What’s the role of the semi lunar valves
Prevent the backflow of blood
What are the three functions of the cardiovascular System
Transporting oxygen carbon dioxide and nutrients
Clotting wounds
Regulating body temperature
What is vasodilation
When blood vessels come to the surface of the skin and enlarge to return body back to normal temperature
What is vasoconstriction
When blood vessels at the skin surface close to allow blood to be taken away from the skin surface to prevent losing heat
What is stroke volume
The volume of blood pumped by the ventricles Each contraction
What is cardiac output
Volume of blood pumped from the heart every minute it’s calculated by multiplying heart rate by stroke volume
What is anaerobic exercise
Short periods of time without oxygen by powerful contractions
In anaerobic exercise what is glucose is broken down into
Lactic acid
What is aerobic exercise
Exercise with oxygen that’s converted into water and carbon dioxide
What is the short term effects of exercise on the cardiovascular system
Increased heart rate increase stroke volume and cardiac output
What’s the short term effects of exercise On the respiratory system
Increase breathing rate and increased tidal volume
