1What are the 3 ways the PCT transports things and what is transported?
Active transport for Sodium
Seconfary active transport for
glucose
amino acids
vitamins
ions
Obligatory = H2O
2What percentage of nutrients, sodium, and water are reabsorbed?
100% Nutritents
90% Na+
60-90% H2O
3What is the counter current multiplier?
This is the change in pressures as we descend down the loop of henle,
descending water leaks out due to water gradients
ascending side sodium moves in due to water gradients
4What are some causes for Repsiratory acidosis? and would the kidney compensate?
COPD
Asthma
Fibrosis
Drug / ETOH
Compensation:
dump HCO3 and reabsorb H back into collecting ducts
5What is the function of ADH on the DCT?
When low BP is sensed ADH is released increasing perm of water increasing blood volume
6What is tubular secretions in the collecting tubes?
a way the body controls pH by absorbing or secreting H+ and HCO3- ions
7If you are acidic what would we expect from tubular secretions?
We would expect to secrete HCO3- and uptake more H ions into the collecting tubes. adding more buffer to blood and removing h ions
8If you are alkaline how might the tubular secretion react?
We would expect to see a secretion of H ions and uptake in HCO3 ions back int o the collecting tubes.
9What are some causes for Repsiratory acidosis? and would the kidney compensate?
COPD
Asthma
Fibrosis
Drug / ETOH
Compensation:
dump HCO3 and reabsorb H back into collecting ducts
10What are some causes for Metabolic acidosis ? and how do we compensate ?
Diabtetes - break down of lipids tanks pH
Diarhea
compensation :
increase respiratory rate to decrease CO2
11What are some causes for respiratory alkalosis ?
Hysteria / anxiety
Respirators
12What are some causes for metabolic alkalosis ?
exessive vomiting
Execesive antacid ingestion
