The (a) detects changes in chemicals in the blood such as (b) and carbon dioxide. This sends a signal to the (c) in the brain, which passes the signal on to the (d) , also known as the pacemaker. Both atrium contract and the signal reaches the (e) which re-directs the signal down the HIS Bundle on to the Purkinje Fibres, which contract both ventricles
What separates the left and right side of the heart?
Septum
Atrium
Ventricle
Myocardium
(a) volume refers to the volume of blood pumped per beat. At rest, this is (b) for an adult. During exercise, this (c) as a short-term effect of exercise. Long-term, the heart gets stronger known as (d) , which increases stroke volume at rest. As a result, (e) decreases at rest.
Which valve separates the aorta and the left ventricle?
Tricuspid Valve
Bicuspid Valve
Aortic Valve
Pulmonary Valve
During exercise, (a) output increases to meet energy and waste demands
Which blood vessel allows for diffusion?
Arteriole
Plasma
Capillaries
Venules
Deoxygenated blood travels from the (a) to the (b) into the right ventricle. It passes through the (c) and into the pulmonary artery. This flows off to the (d) where CO2 diffuses into the alveoli and O2 into the (e) . This returns in the pulmonary vein back to the heart.
Which elastic blood vessel contains smooth muscle in the walls and has high pressure blood inside?
Capillary
Artery
The Heart
Vein
In order to prevent backflow, veins contain (a) .
Match the following components of blood
Plasma
Suspends all components of blood to support transport
Platelet
Clots wounds
Red blood cells
Transport O2 and Co2
White blood cells
Fight infection and disease
Reorder the following as the electrical signal reaches the heart from the medulla oblongata
SA Node
AV Node
Bundle of HIS
Purkinje Fibres
What sort of blood travels in the pulmonary artery?
Deoxygenated
Oxygenated
Cold
Altitude
