Circulatory system (path of blood) Flashcards
Diffusion in the circulatory system
- In the lungs, capillaries absorb oxygen from inhaled air into the bloodstream and release carbon dioxide for exhalation.
- in a process called diffusion, oxygen moves from the alveoli to the blood through the capillaries (tiny blood vessels) lining the alveolar walls.
the blue, right side of the system deals with what type of blood?
deoxygenated blood, blood that lacks oxygen
the left side (the red) deals with what type of blood?
oxygenated blood, blood full of oxygen
deoxygenated blood goes through what type of circulation?
pulmonary circulation
what is systemic circulation?
(the left side of the heart) carries oxygenated blood from the heart to the rest of the body
Once the oxygenated blood enters the body, how does gas exchange occur in body cells?
the oxygenated blood inters the artery, travels through the arteriol, enters the capillary, exits it from the venule, which leads it to the vein, deoxygenated blood now leaves and goes to the heart
Path of deoxygenated blood from body, through heart, to lungs.
Superior vena cava (upper body)/inferior vena cava (lower body)→ the right atrium →tricuspid valve → right ventricle → pulmonary valve → pulmonary trunk→ pulmonary artery → lungs
path of oxygenated blood from lungs, through heart, to body.
lungs → pulmonary vein → left atrium → mitral valve → left ventricle → aortic valve → aorta → cells in body
