FOUR CHAMBERS
LEFT VENTRICLE
Pumps oxygenated blood from lungs to body
RIGHT VENTRICLE
is the chamber within the heart that is responsible for pumping oxygen-depleted blood to the lungs.
LEFT ATRIUM
It plays the vital role of receiving blood from the lungs via the pulmonary veins and pumping it to the left ventricle.
RIGHT ATRIUM
which function as receiving chambers for blood entering the heart
PERICARDIUM
Lubricates the heart
Prevents excessive dilation of the heart in cases of acute volume overload
Protects it from infections coming from other organs
Sets heart in mediastinum and limits its motion
It takes in deoxygenated blood through the veins and delivers it to the lungs for oxygenation before pumping it into the various arteries
Day 50
aorta - pulmonary trunk are already separated
Day 49
absorption pulmonary veins
Four-chambered heart
Day 42

Day 25
cardiogenic loop is formed
Day 23
first contraction
Only half a heart tube
Day 22
Fusion endocardial tubes
Day 21
Endocardial tubes appear
Day 20
There cardiogenic plate
is the main respiratory muscle that allows us to inhale and exhale
Gas exchange of oxygen and carbon dioxide takes
When someone takes a breath through their nose or mouth, the air travels into the larynx
LOBAR BRONCHUS
LEFT INFERIOR
LEFT SUPERIOR
RIGHT INFERIOR
RIGHT MIDDLE
RIGHT SUPERIOR
distributed to tissues all over the body and expel carbon dioxid
LEFT
TWO LOBES
RIGHT
THREE LOBES
INFERIOR
MIDDLE
SUPERIOR
the site of the tracheal bifurcation at the lower end of the trachea
uns down behind the breastbone
begins just under the larynx
also protects the body from choking on food that would normally obstruct the airway.
It directs the passage of air and food between the mouth and nose into esophagus and larynx
FUNCTION
condition the air to be received by the other areas of the respiratory tract
Increased cell size
Increases the number of alveoli
fusion of a unique capillary bilayer
Interdental wall thinning
alveoli formation
Development of secondary septa
Training saccules
Formation of the transitional airspace
It appears surfactant
epithelial differentiation
Growth of the capillary bed
Forming acini
vascular growth
Development of the bronchial tree to level terminal bronchioles
Occurrence of pulmonary circulation
Day 37
The lobar bronchi begin their training
Day 33
the division occurs in two branches Main and lung buds
development of large airways
It originates from the mesoderm
