Transport

Transport (Medicine)

Transport (pronounced: trans-port) in the context of medicine refers to the movement or transfer of substances, cells, or even patients from one location to another. This term is used in various branches of medicine, including physiology, biochemistry, and emergency medicine.

Etymology

The term 'transport' originates from the Latin word 'transportare', which means 'to carry across'. In the medical context, it has been used since the early 19th century.

Physiology

In physiology, transport refers to the movement of substances across cell membranes. This can occur through various mechanisms, including active transport, passive transport, and facilitated diffusion.

• Active transport involves the use of energy to move substances against a concentration gradient. This is often mediated by transport proteins.
• Passive transport refers to the movement of substances down a concentration gradient, without the need for energy. This includes diffusion and osmosis.
• Facilitated diffusion is a type of passive transport that involves the use of transport proteins to aid the movement of substances across the cell membrane.

Biochemistry

In biochemistry, transport is often used to describe the movement of molecules within a cell or between cells. This includes the transport of proteins, lipids, and nucleic acids.

Emergency Medicine

In emergency medicine, transport refers to the movement of patients from the scene of an incident to a healthcare facility. This can be done by ambulance, helicopter, or other means. The term 'transport' can also refer to the transfer of patients between healthcare facilities.
