Utente
sternum
thoracic spine
ribs
superior and inferior thoracic apertures
1) manubrium: suprasternal notch that lines up with TII
2) body of sternum: sternal angle that lines up with TIV/ TV
3) xiphoid process: xphisternal joint that lines up with TIX
pulmonary (2)
mediastinum
1) IVC
2) SVC
3) pulmonary veins (4)
4) PT
4) AORTA- ascending aorta
- arch of aorta
- descending aorta
results from shunt mechanism in fetal blood flow called Ductus arterious essentially since lungs develop last and heart develops first to prevent blood flow from to goingunderdeveloped lungs from PT, a duct shunts blood to aorta instead when oxygenated blood is received from mothers placenta/UC
1) Deoxygenated blood enters from SVC/IVC into RA. 2)blood from RA goes through AVV and into RV
3) blood from RV goes through PSIV and to PT where deoxygenated blood goes to the lungs. 4) oxygenated blood from lungs enters through PV (4)
5) O blood enters LA goes through AVV and into Lv
6) Blood from LV goes through ASLV and Circulates throughout whole body from the aorta
-Inner surface is smooth
- Pectinate: rough outer surface for contraction
- cresta terminalis: separates the two types of muscle
Interartial septum: seperates LA and RA
Another fetal mechanism called foramen ovale
shunt between left and nght Atrium to skip blood flow from going to ventricles
Atroventncular valves: 1)TRicuspid valve
2)BIcuspid valve
semilunar valves: 1) pulmonary semilunar
2) Aortic semilunar valve
1) Aortic valve → Parasternal line: Right second intercostal
2)Pulmonary valve → parasternal line: Left second intercostal
3)TRIcuspidvalve→Parasternal line: left fifth intercostal
4) BIcuspid valve → Midclavicular line: left fifth intercostal
1) fibrous pericardium
2) Parietal pericardium
3) visceral pericardium
Pericardial cavity→ space between Parietal and visceral filled with serous fluid
1) Transverse → PT, aorta
2) oblique → Posterior PT
condition of built up serous fluid that can be treated through Pericardiocentisis→ needle insertion between xiphold process and costal margin and directed to anterior wall of Right ventricle
