The Cl- shift, also known as the Hamburger phenomenon, occurs in red blood cells (RBCs) during systemic gas exchange. As carbon dioxide (CO2) enters the RBCs from the tissues, it combines with water to form carbonic acid, which dissociates into bicarbonate (HCO3-) and hydrogen ions (H+). To maintain electrical neutrality, bicarbonate is transported out of the RBCs into the plasma while chloride ions (Cl-) move into the cells, thus the “shift” of Cl- into the RBCs. This process helps facilitate the transport of CO2 from tissues to the lungs for exhalation.
haemoglobin present in the RBC helps in gaseous exchange and transport in humans .. where as in plants its through stomata , cuticle , lenticels etc....
Internal Respiration
internal respiration
The four phases of gas exchange in humans are ventilation, pulmonary diffusion, transport of gases in the blood, and systemic diffusion. Ventilation involves the movement of air in and out of the lungs. Pulmonary diffusion is the exchange of oxygen and carbon dioxide between the alveoli and the blood. Transport of gases involves the carriage of oxygen by hemoglobin and carbon dioxide by plasma. Systemic diffusion is the exchange of oxygen and carbon dioxide between the blood and body tissues.
Gas exchange is a function of respiration not digestion.
Terminal bronchioles eventually terminate in the respiratory bronchioles, which are the first parts of the respiratory zone of the lungs. From the respiratory bronchioles, air moves into alveolar ducts and finally into alveolar sacs, where gas exchange occurs. This transition marks the shift from conducting airways to the site of gas exchange.
Alveoli is where gas exchange occurs.
The lungs have a greater density of pulmonary capillaries compared to systemic capillaries due to the need for efficient gas exchange. The pulmonary capillary network surrounds the alveoli, allowing for optimal diffusion of oxygen and carbon dioxide between the air and blood. This high density facilitates the rapid exchange of gases necessary for maintaining proper oxygen levels in the bloodstream while removing carbon dioxide. Additionally, the lower pressure in the pulmonary circulation allows for a larger surface area for gas exchange without risking damage to the delicate alveolar structures.
You will use more gas due to the higher RPM. The shift light is to help you to save on gas milage.
They are RBC's i.e. red blood cells.
Pulmonary Circulation carries deoxygenated blood to the lungs to receive oxygen, while the Systemic Circulation carries the oxygenated blood throughout the body so the oxygen can be used, returning to the Pulmonary Circulation as deoxygenated blood.
The pulmonary system is responsible for exchanging oxygen and carbon dioxide between the lungs and blood, while the systemic system delivers oxygen and nutrients to the body's tissues and removes waste products. The pulmonary system deals with gas exchange specifically in the lungs, while the systemic system involves the entire body's circulation of blood.
