Passive mass transport is the diffusion of substrates across a biomembrane. This diffusion occurs along the concentration gradient and does not require energy. The diffusion process may be impaired in the intestines of HIV patients, for example. What is passive mass transfer? Passive solute transport is the diffusion of substrates across the biomembrane of cells … Passive Mass Transfer: Function, Role & Diseases
Convection plays a major role in the thermoregulation of the body. It characterizes heat transport in the body and heat dissipation to the outside world. Disturbances in heat exchange can be caused by disease and severely affect the body’s heat balance. What is convection? In convection, heat energy is transported from the heat source to … Convection: Function, Tasks, Role & Diseases
The placental barrier separates the mother’s blood circulation from that of the baby. Through this tissue filter, the two blood circulations operate independently of each other. What is the placental barrier? The placental barrier separates the mother’s bloodstream from that of the baby. Through this tissue filter, the two blood circuits operate independently of each … Placental Barrier: Function, Role & Diseases
Active solute transport is a form of transport of substrates across a biomembrane. Active transport occurs against a concentration or charge gradient and occurs under energy consumption. In mitochondriopathies, this process is impaired. What is active solute transport? Active solute transport is a mode of transport of substrates across a biomembrane. In the human body, … Active Solute Transport: Function, Role & Diseases
Deoxygenation is the dissociation of oxygen molecules from hemoglobin molecules in human blood. The body’s oxygen supply is built on a cycle of oxygenation and deoxygenation. In phenomena such as smoke inhalation, this cycle is disrupted. What is deoxygenation? Deoxygenation is the dissociation of oxygen molecules from hemoglobin molecules in human blood. Chemical deoxygenation involves … Deoxygenation: Function, Role & Diseases
Semipermeability refers to biomembranes that are selectively permeable to certain substances and cannot be passed by other substances. Semipermeability is the basis of osmosis and characterizes the cells of all living things. Disturbances in semipermeability have devastating consequences for electrolyte and water balance in cellular compartments. What is semipermeability? Semipermeability refers to biomembranes that are … Semipermeability: Function, Role & Diseases
Without respiration there is no metabolism and without metabolism there is no life. Thus, humans and all vertebrates depend on gas exchange via pulmonary respiration. What is gas exchange? Without respiration no metabolism and without metabolism no life. Thus, humans and all vertebrates depend on gas exchange via pulmonary respiration. Oxygen, which is so vital … Gas Exchange: Function, Tasks, Role & Diseases
Oxygen (O2) is essential for humans. Oxygen uptake from the air we breathe takes place in the lungs. From there, the oxygen-rich blood is transported to the cells. These need the oxygen as part of internal cellular respiration for energy production. What is oxygen uptake? Oxygen (O2) is essential for humans. Oxygen uptake from the … Oxygen Uptake: Function, Tasks, Role & Diseases
The pulmonary circulation, also called the small circulation, is part of the human cardiovascular system. It regulates the transport of blood between the heart and the lungs and is used for gas exchange, i.e., the absorption of oxygen into the blood and the release of carbon dioxide into the air we breathe. What is the … Pulmonary Circulation: Function, Purpose & Diseases
Depolarization is the cancellation of charge differences on the two membrane sides of a nerve or muscle cell. The membrane potential changes to a less negative one as a result. In diseases such as epilepsy, the depolarization behavior of nerve cells changes. What is depolarization? Depolarization is the cancellation of charge differences on the two … Depolarization: Function, Tasks, Role & Diseases
Blood contact time is the time during which blood circulates in the small blood vessels of the lungs and during which diffusion of respiratory gases occurs. Therefore, blood contact time has an important effect on blood oxygen levels. What is blood contact time? Blood contact time refers to the amount of time that blood spends … Blood Contact Time: Function, Tasks, Role & Diseases
Diffusion is when liquids or gases mix by means of Brownian molecular motion. In the body, diffusion occurs for the exchange of substances between cells and for the exchange of gases in the lungs. Diffusion disorders in the lungs cause respiratory insufficiency. What is diffusion? Diffusion occurs in the body for the exchange of substances … Diffusion: Function, Tasks, Role & Diseases
