Structure
What are the 4 chambers of the heart?
Right atrium & right ventricle
Left atrium & left ventricle
What wall separates the left side and right side of the heart?
septum
located between the right atrium and right ventricle, it prevents the backflow of blood from the ventricle to the atrium.
tricuspid valve
what are capillaries?
the smallest blood vessels which connect the smallest arteries with the smallest veins.
The body largest artery and it takes oxygenated blood from the left ventricle to the body
Aorta
oxygenated blood returns to the left atrium via the _______. the left ventricle then eject this oxygenated blood into the _______.
pulmonary veins & aorta
Located between the right ventricle and the pulmonary artery.
Pulmonary valve
What is the function of the Tricuspid valve?
To prevent backflow of blood from the ventricle to the atrium
which blood vessel brings deoxygenated blood from the upper body to the heart. And empties into the right atrium of the heart.
superior vena cava
The heart is a large muscular pump and is divided into two halves. what are these called and state their function?
The right-hand side of the heart is responsible for pumping deoxygenated blood to the lungs.
The left-hand side pumps oxygenated blood around the body.
Located between the left atrium and the left ventricle.
Mitral valve.
blood vessels that carry blood away from the heart?
Arteries
The heart located in the _________and surrounded by a protective membrane sac called__________.
Of the chest and pericardium
There is a wall between the two atria called ________. There is another wall between the two ventricles, and it is called the _________.
the atrial septum & ventricular septum
Name the four types of valves in the heart?
Tricuspid valve.
Pulmonary valve.
Mitral valve.
Aortic valve
blood vessels that carry waste containing blood from the tissues back to the heart
Veins
a thin, inner layer that makes up the lining of the 4 chambers and the valves in your heart.
Endocardium
Oxygen-poor blood returns from the body to the heart through the _______________and ________________ and into the right atrium.
superior vena cava and inferior vena cava
Located between the left ventricle and the aorta.
