Q

what are the ventricles

A
  1. discharge chambers which are the actual pumps of the heart
  2. enlarge chambers in the Brian that contains chorus plexuses

12
Q

what happens in the pulmonary circuit pump

A

the right ventricle carries blood to the lungs for gas exchange (where oxygen enters the blood, carbon dioxide leaves the blood) and back to the left atrium which is the receiving chamber of the heart.

Q

what is the inferior vena cava

A

the larger veins that carries blood from veins inferior to the diaphragm back to the right atrium

17
Q

what is the pulmonary trunk

A

the large artery connecting the right ventricle with the pulmonary arteries

18
Q

what are the pulmonary arteries

A

parties that branch off the pulmonary trunk and carry blood to the lungs

19
Q

what do arteries do

A

carry blood away from the heart

20
Q

what happens when the pulmonary arteries carry blood to the lungs

A

oxygen is picked up and carbon dioxide is unloaded

21
Q

what is oxygen poor and oxygen rich

A

The right side of the heart pumps oxygen-poor blood from the body to the lungs, where it receives oxygen. The left side of the heart pumps oxygen-rich blood from the lungs to the body.

22
Q

what is the systematic circuit

A

system of blood vessels that carries nutrients and oxygen-rich blood to all body organs

23
Q

how is pulmonary circuit different from the systematic circuit

A

the pulmonary involves gas exchange while the systemic involves all body organs getting oxygenated blood

24
Q

which circuit is more powerful and thick

A

the systematic circuit because the walls are thicker and it is a more powerful pump

25
Q

what is the aorta

A

major systematic artery that comes from the left ventricle of the heart

26
Q

what are systematic veins

A

transport blood from the body tissue to the right atrium of the heart.

27
Q

right ventricle

A

The right ventricle pumps blood low in oxygen to the lung

28
Q

left ventricle

A

The left ventricle pumps blood full of oxygen out to the body.

29
Q

what is the location of the heart in the thorax

A

the heart is in the mediastinum between the lungs
