Most cells are anchorage dependent and must be cultured while attached to a solid or semi-solid substrate (adherent or monolayer culture), while others can be grown floating in the culture medium (suspension culture).

#Unit 7. System Physiology – Animal

In the thick segment of the ascending loop of Henle, paracellular reabsorption of cations, such as Mg++, Ca++, Na+, and K+ occur

#Id: 5546

#Unit 7. System Physiology – Animal

Paracellular reabsorption of cations (K+) causes slight positive charge (+8)of the tubular lumen relative to the interstitial fluid

TLS Online TPP Program

#Id: 5547

#Unit 7. System Physiology – Animal

Positive charge forces cations such as Mg++ and Ca++ to diffuse from the tubular lumen through the paracellular space and into the interstitial fluid
