Oxygen and Carbon Dioxide Transport in the Blood

WebOnce your blood enters your aorta, it begins its journey through your systemic circuit. This is the part of your circulatory system that carries blood throughout your body. After delivering oxygen to your organs and tissues, this blood returns to your heart’s right atrium. WebPulmonary diffusion is further aided by a thin respiratory membrane composed of the membrane of the alveolar cells and the cells making up the wall of the capillary. So, the respiratory membrane through which gases must pass to move between the blood and the air within the alveoli is only two cells thick. sympy characteristic equationWebUnlike capillaries in the systemic circuit, in the pulmonary circuit, _____ blood enters the capillaries from the arterioles and _____ blood leaves the capillaries for the venules. ... alveoli;pulmonary capillaries.
