The Heart
The side of the heart that pumps oxygenated blood to the body
Left
Blood cell that transports oxygen
Red blood cells
Blood vessel that carries blood away from the heart
Artery
Circulation that carries blood between the heart and lungs
Pulmonary circulation
What is the normal body temperature the body aims to maintain?
37 degrees
The name of the wall that separates the left and right side of the heart
Septum
Protein inside red blood cells that carry oxygen
Haemoglobin
Capillaries
Circulation that carries blood between the heart and the rest of the body
Systemic circulation
What is the name of the process where blood vessels near the skin widen to increase heat loss?
Vasodilation
The chamber that pumps oxygenated blood into the aorta
Left ventricle
The main function of platelets
Blood clotting
The blood vessel that returns oxygenated blood from the lungs to the heart
Pulmonary vein
Does the pulmonary artery carry oxygenated or deoxygenated blood
Deoxygenated
What is the name of the process where blood vessels near the skin narrow to reduce heat loss?
Vasoconstriction
Name of the valve found between the right atrium and right ventricle
Tricuspid valve
Which component of blood makes up the largest percentage of blood volume?
Plasma
The largest artery in the body
Aorta
Does the pulmonary vein carry oxygenated or deoxygenated blood
Oxygenated
Explain how vasodilation helps cool the body during exercise.
Blood vessels near the skin widen, allowing more warm blood to flow close to the skin's surface where heat can be lost to the environment
Starting at the right atrium, list the path that blood takes through the heart until it reaches the muscles
Right atrium - right ventricle - pulmonary artery - lungs - pulmonary vein - left atrium - left ventricle - aorta - body
A student has a weakened immune system and frequently becomes sick. Which component of blood is most likely not functioning effectively?
White blood cell
Place these blood vessels in the correct order as blood travels from the heart to the body's cells and back again:
Artery - capillary - vein
A red blood cell has just picked up oxygen in the lungs. Name the first chamber of the heart, the last chamber of the heart, and the major blood vessel it travels through before reaching the body.
Left atrium - left ventricle - aorta
During a winter football match, a player stands on the bench for 20 minutes and begins to feel cold.
Name two physiological responses the body may use to maintain body temperature and explain how each helps
Vasoconstriction: Narrows blood vessels near the skin to reduce heat loss.
Shivering: Involuntary muscle contractions produce heat to warm the body.
