Trace the pathway of blood from the renal artery to the renal vein. Be certain to state the anatomical landmarks and physiological actions along the route. Oxygen diffuses from the alveoli to the blood because: a. PO2 is higher in the blood. b. PO2 is lower in the blood. c. CO2 ...
The respiratory tract is a pathway for air to reach the lungs. The tract is not responsible for gaseous exchange, it allows the foul free air to enter the lungs through nostrils and trachea. The pharynx is the connective unit of the larynx and nasal cavity....
Nanoparticles (<0.1聽渭m in one dimension) may easily reach the brain from the respiratory tract via sensory neurons and transport from the distal alveoli into the blood or lymph as free particles or inside phagocytic cells. These mechanisms and subsequent biologic responses may be influenced by ...
The purpose of the respiratory mucosa is to condition air before it enters the alveoli. Explain what the term 'condition' means. After exhaling and then holding your breath, did you have a desire for inspiration or expiration? Explain.
Exhaled breath VOCs associated with inflammatory bowel disease probably arise from microbe-associated gases originating in the gut that diffuse into the bloodstream and are released into lung alveoli [26]. Certain VOCs highly associated and correlated with the presence of specific diseases and metabolic...
