Q

a

A

superior vena cava

Blood Flow to the Heart: The superior vena cava carries oxygen-poor blood from the upper body back to the right atrium of the heart. This blood is returning from all parts of the body after delivering oxygen and picking up waste products.

Next Step to the Lungs: From the right atrium, the blood then moves to the right ventricle, which pumps it to the lungs via the pulmonary arteries. In the lungs, the blood gets rid of carbon dioxide and picks up oxygen, becoming oxygen-rich again.

Summary:
Superior Vena Cava: Brings oxygen-poor blood back to the heart from the body.
Heart to Lungs: The heart then sends that blood to the lungs to get oxygen.

A

Pericardium
The pericardium is a thin, protective sac that surrounds the heart. It helps keep the heart in place and reduces friction as the heart beats.

36
Q

j

A

apex of heart

37
Q

What is the pericardium?

A

3 layers that are going to completely enclose the heart
- continuous layer and no openings within it

38
Q

myocardium

A

thick middle layer of the heart made of muscle. It is responsible for contracting and pumping blood throughout the body.

39
Q

a

A

Fibrous pericardium
- dense connective tissue that’s going to protect the heart and hold in place and to keep it from overfilling
- if something is wrong, we don’t want to just to get bigger and bigger and bigger
tough, outer layer of the pericardium that surrounds the heart. It helps protect the heart and keeps it in place within the chest.

d

A

Epicardium (visercal layer of serous pericardium)

43
Q

Inferior border of the fibrous pericardium

A

adhere the heart to our inferior border of the middle mediastinum

44
Q

What is the middle mediastimum?

A

middle mediastinum is the space in your chest between your lungs. It holds the heart and big blood vessels that carry blood to and from the heart.

45
Q

Superior border of the fibrous pericardium

A

Adhere the heart to the great vessels

The great vessels are big tubes that carry blood to and from the heart. They include the aorta, which sends blood to the body, and the superior and inferior vena cavae, which bring blood back to the heart.

46
Q

What is the serous pericardium

A

The serous pericardium is a thin, smooth layer that surrounds the heart and helps reduce friction as the heart beats. It has two parts: the outer layer (parietal pericardium) and the inner layer (visceral pericardium), which is also called the epicardium.

47
Q

What is the pericardial cavity?

A
  • pariteal and visceral are continuous with each other but there is a space bewteen
    The space between the parietal layer of serous pericardium and visceral (epicardium) layer of serous pericardium
48
Q

Fluid in the serous pericardium

A
  • releasing serous fluid
  • preventing the parietal and epicardium (visceral) from rubbing against each other
49
Q

What is cardiac Tamponade?

A
  • increased serous fluid within that pericardial sac or pericardial cavity
  • fibrous pericardium is a tough outer layer that stops the heart from overfilling
  • can’t push towards the fiborus pericardium, start pushing in wards
  • compressing the heart can affect how much it can fill and how wide it can expand to take in blood
  • if the heart is taking in a bit of blood at a time, the body still needs the same amount of blood, then the heart’s going to work overtime to compensate for how much it got shrunk down
50
Q

Causes for cardiac Tampondade

A
  • Inflection, inflammation
  • inflammation is called pericarditis
51
Q

a

A

superior vena cava
- drain all of the blood superior to the heart (arms, head, neck) to the heart, it is a vein

The superior vena cava is a big vein that carries oxygen-poor blood from the upper part of your body, like your head and arms, back to the heart. It brings this blood to the right atrium, which is one of the heart’s chambers.

52
Q

d

A

Inferior vena cava
- drain everything inferior to the heart, thorax, abdomen, trunk

The thorax is the part of your body between your neck and your stomach. It contains important organs like the heart and lungs, and it’s protected by the ribs
The inferior vena cava is a large vein that carries oxygen-poor blood from the lower part of your body, like your legs and abdomen, back to the heart. It also brings this blood to the right atrium of the heart.

53
Q

e

A

aorta
- has three subcomponents to the thorax
- ascending (anterior)
- aortic arch
- descending (posterior)
* from the anterior view, we should be able to see the ascending aorta and also the arch of the aorta
largest artery in your body. It carries oxygen-rich blood from the heart to all parts of the body.

54
Q

what is the purpose of the aorta?

A

continue all the way down to the thorax and going to continue to into the abdomen itself. it gives off oxygenated and nutrient rich blood.

55
Q

f

A

Pulmonary trunk
- splits into the left pulmonary artery and right, going to the lungs
large blood vessel that carries oxygen-poor blood from the heart to the lungs. It splits into two smaller arteries, one for each lung, so the blood can get oxygen.

56
Q

b

A

right atrium
chamber of the heart that receives oxygen-poor blood from the body through the superior and inferior vena cavae. It then sends this blood to the right ventricle, which pumps it to the lungs to get oxygen.

57
Q

g

A

left atrium

chamber of the heart that receives oxygen-rich blood from the lungs through the pulmonary veins. It then sends this blood to the left ventricle, which pumps it out to the rest of the body.

58
Q

d

A

right ventricle
chamber of the heart that pumps oxygen-poor blood to the lungs. It receives blood from the right atrium and sends it to the lungs to get oxygen.

  • most of the anterior view
59
Q

g

A

left ventricle

chamber of the heart that pumps oxygen-rich blood to the entire body. It receives blood from the left atrium and has thick walls to push the blood out with strong force.

60
Q

a

A

Pulmonary arteries
- if it was continuing down, it would the descending aorta
carry oxygen-poor blood from the right ventricle of the heart to the lungs. They split into two arteries, one going into each lung where teh blood gets oxygen

61
Q

b

A

Left atrium
- receives oxygen-rich blood from the lungs through the pulmonary veins. Sends this blood to the left ventricle, which pumps it out to the rest of teh body

62
Q

d

A

Left ventricle
pumps oxygen-rich blood to the entire body. Receives blood from the left atrium and has thick muscular walls to push the blood out with strong force through the aorta.

63
Q

e

A

aortic arch
curved part of the aorta that connects the ascending aorta to the descending aorta. Branches out to supply oxygen rich blood to the head, neck, arms and other parts of the body

64
Q

f

A

superior vena cava
carries oxygen-poor blood from the upper body including the head, neck and arms, back to the heart. Delivers this blood to the right atrium

65
Q

h

A

inferior vena cava
a large vein that carries oxygen-poor blood from the lower body, including the legs and abdomen, back to the heart. It delivers this blood to the right atrium, which is one of the heart’s chambers

66
Q

i

A

right ventricle
pumps oxygenated poor-blood to the lungs, receives this blood from the right atrium and sends it through the pulmonary arterires to the lungs, where the blood gets oxygen

67
Q

c

A

Coronary sinus
a large vein that collects oxygen-poor blood from the heart muscle itself. It gathers blood from smaller veins and drains it into the right atrium of the heart, where the blood can then be sent to the lungs to get oxygen.

68
Q

g

A

pulmonary veins
- blood vessels that carry oxygen-rich blood from the lungs back to the heart
- There are four pulmonary veins-two from each lung-that deliver this oxygenated blood to the left atrium, where it is then sent to the left ventricle for distribution to the rest of the body

75
Q

First flow of blood

A

Superior vena cava, inferior vena cava, coronary sinus
- going to bring back oxygenated poor blood into the heart

76
Q

Second blood flow

A
  • dump that oxygen poor blood into the right atrium (from the superior vena cava, inferior vena cava and coronary sinus) , which is the first chamber
77
Q

Third blood flow

A
  • take the oxygen-poor blood (from the superior vena cava, inferior vena cava, and coronary sinus) which went to the right atrium and now it goes to the right ventricle
78
Q

Fourth blood flow

A
  • take the oxygen-poor blood (came from the superior vena cava, inferior vena cava, coronary sinus) went to the right atrium, then right ventricle, then pulmonary trunk/arteries
  • the pulmonary trunk splits off into left and right
79
Q

Fifth flow of blood

A

oxygen-poor blood (from the superior vena cava, inferior vena cava and coronary sinus) goes to the right atrium, then right ventricle, then to the pulmonary trunk/arteries that get divided in two to each of the lungs

80
Q

Sixth flow of blood

A

oxygen-poor blood (from the superior vena cava, inferior vena cava, coronary sinus) goes to the right atrium, then right ventricle, then to pulmonary trunk/arteries, which divide into two pulmonary arteries that go to each lung on each side, then the blood comes back from each side of the lungs via the pulmonary veins (4 of them, two from each side)

  • typically within the body, the arteries are going to carry oxygenated blood and the veins are going to carry deoxygenated blood. But the pulmonary circuit is the only place in the body that we’re going to see an exception to this rule
81
Q

Seventh flow of blood

A

oxygen-poor blood (from the superior vena cava, inferior vena cava, coronary sinus) goes to the right atrium, then right ventricle, then into the pulmonary artery (then divides into left and right pulmonary arteries), goes into the lungs, comes through the 4 pulmonary veins (2 on each side) to the left atrium

82
Q

Eight flow of blood

A

oxygenated-poor blood (comes from the superior vena cava, inferior vena cava, coronary sinus) goes to the right atrium, then the right ventricle, then the pulmonary artery/trunk (which divides into two pulmonary arteries one for each lung), then goes to lung, comes back from lung into 4 pulmonary veins (2 from each side), then into left atrium, then into the left ventricle

83
Q

Ninth flow of blood

A

oxygenated-poor blood comes (from the superior vena cava, inferior vena cava, coronary sinus), goes to the right atrium, then right ventricle, the blood then goes to the pulmonary artery/trunk (these divide into two each one to each lung), the blood comes back from the lung (it is oxygenated blood) through the pulmonary veins (4 veins in total 2 on each side), then go to the left atrium, these go to the left venticle, then to the aorta which goes to the body

  • once the body uses the oxygen, it gives the nasty deoxygenated blood back to the veins taht are going to bring back through the SVC< IVC and coronary artery
