Gas exchange is the physical process by which gases move passively by diffusion across a In aerobic organisms, gas exchange is particularly important for respiration, which The gas exchangers are therefore frequently coupled to g

Gas Exchange • Sites of Gas exchange: - At tissues (between blood & tissues). D6. Transport of respiratory gases Kidney Removes CO˜ Bicarbonate reabsorbed Blood pH is 7.35-7.45 Makes blood more alkaline H+ ions released into urine If it becomes acidic chemoreceptors stimulate hyperventilation Effect of CO˚ on ventilation rate Bohr Shift Chemoreceptors in aorta and carotid artery detect this and send message to medulla Oxygen is transported in the blood in two ways: A small amount of O 2 (1.5 percent) is carried in the plasma as a dissolved gas. Most oxygen (98.5 percent) carried in the blood is bound to the protein hemoglobin in red blood cells. A fully saturated oxyhemoglobin (HbO 2) has four O 2 molecules attached. Transport of respiratory gases. Option D.6 (AHL) U: Oxygen dissociation curves show the affinity of hemoglobin for oxygen.

Chapter 125 t Transport of Respiratory Gases 713 saturated to about 50%. That is, the blood contains 50% of oxygen.

Oxygen is passed from the lungs to the The human body was divided in the following compartments: alveolar, pulmonary capillaries, arterial, venous, tissue capillary and tissues. The gas transport in the The primary purpose of the lung is the exchange of the respiratory gases O2 and CO2 between ambient air and blood. The site of exchange is in the alveoli, where Oxygen is transported from alveoli to the tissue by blood in two forms: 1.
