Respiratory

Question 1

Describe and explain the functions of the Superior Vena Cava?

Answer 1

Collect deoxygenated blood from the upper body and deliver it to the heart for oxygenation
Located within the superior and middle mediastinum

Question 2

Describe and explain the functions of the Aorta?

Answer 2

Largest blood vessel
Cane-shaped artery
Starts in the lower-left ventricle
Passes through your chest and abdominal cavities and ends at your pelvis

Question 3

Describe and explain the functions of the Pulmonary artery?

Answer 3

Carries deoxygenated blood from the heart to the lungs for oxygenation
Starts in the right ventricle, splits into the right and left pulmonary arteries

Question 4

Describe and explain the functions of the Pulmonary veins?

Answer 4

Receive oxygenated blood from the lungs and transport it back to the heart then pumped out to the rest of the body.
Pulmonary capillary network in the lungs into the left atrium of the heart

Question 5

Describe and explain the functions of the Left atrium?

Answer 5

Located in the upper left part of the heart, forming the base of the heart.
Receives oxygenated blood from the four pulmonary veins.
It pumps the oxygenated blood through the left atrioventricular orifice (guarded by the mitral valve) into the left ventricle

Question 6

Describe and explain the functions of the Left ventricle?

Answer 6

Pumps oxygenated blood to the body
Requires a higher workload and pressure than the right ventricle.
Located in the bottom left portion of the heart, below the left atrium and separated by the mitral valve

Question 7

Describe and explain the functions of the Right ventricle?

Answer 7

Located in the lower right portion of the heart, below the right atrium and opposite the left ventricle
Receives deoxygenated blood from the right atrium and pumps it to the lungs via the pulmonary artery becoming oxygenated

Question 8

Describe and explain the functions of the Inferior vena cava?

Answer 8

Transports deoxygenated blood from lower extremities and abdomen back to the right atrium of the heart

Question 9

Describe and explain the functions of the Right atrium?

Answer 9

Located on the upper right side.
Blood enters through the superior vena cava (from the upper body) and inferior vena cava (from the lower body).
Then pumps this blood into the right ventricle through the tricuspid valve.
