3.7 Homeostasis & The Kidney

Heparin

Heparin

________ is put into the blood to thin and reduce clotting.

negative feedback

Deviations from the set point are corrected by ________ so the set point is restored.

Ultrafiltration

________- High blood pressure in the capillaries of the glomerulus forces out the plasma of the blood.

Vesicles

________ containing aquaporins move and fuse with the cell membrane.

Osmoregulation

________- regulating the water content of body fluids.

Forestations

________- Gaps between the cells form the glomerular blood vessels creating a path of flow resistance away from the glomerulus.

ADH

________ increases the permeability of the DCT and collecting duct to allow more water to be reabsorbed from the medulla and urine is more concentrated.

adrenal glands

The ________ release aldosterone in response to low sodium concentration in the blood plasma or low blood pressure.

Podocytes

________- form the inner membrane of the Bowman's capsule.

bloodstream

It is carried from the liver to the kidneys in the ________.

Positive Feedback

________- Enhances the size of the stimulus, and causes movement further away from the set point.

Dialysis & Kidney Transplant

Treatments: Balance fluids in the blood, Medication to control K+ and Ca+, Low protein diet, Drugs to reduce blood pressure, ________.

amino acids

All Glucose and ________ are reabsorbed by Co- Transport with Sodium Ions into the cuboidal epithelial cells by facilitated diffusion.

Selective reabsorption

________ happened in the Proximal convoluted tubule.

Deamination

________- The amino group is removed from the amino acid to form Ammonia which is excreted as Nitrogen is toxic.

Effector

________- coordinates the response to restore the set point.

Excretion

________- The removal of metabolic waste made by the body.

peritoneal cavity

An incision is made into the belly and a catheter is inserted into the ________.

high pressure

Blood in the kidney is under ________ arriving from the renal artery.

Urea

________ is the main nitrogenous waste product in humans.

aldosterone hormone

The ________ increases the kidney's salt retention.

Basement Membrane

________- Filtration barrier, cells and large plasma protein macromolecules can not pass through.

Urea synthesis

________ requires a lot of energy, but it is a lot less toxic than ammonia.

cytoplasm of cells

Controls the water balance of the blood, tissue fluid and ________.

podocytes

The ________ create gaps for the filtrate to pass between the cells.

filtrate

The ________ is at its most concentrated at the end of the collecting duct and forms urine.

Negative Feedback

________- Changes in the internal environment are restored to their original level by ________.

ADH

________ binds to receptors in the DCT.

Fluid

________ is pumped into the peritoneal cavity through the catheter, blood passes through and waste products and excess fluid are drawn into the dialysis ________ and drained into a bag.

Urea

________ is made in the liver by combining 2 molecules of ammonia with 1 molecule of Carbon Dioxide.

filtrate

The ________ flows down the descending limb and flows up the ascending limb.

ADH

________ is for Osmoregulation.

ADH

________ regulates water reabsorption in the Distal Convoluted Tubule.

ADH

________ is released from the pituitary gland and causes the opening of cell membrane pores called aquaporins, allowing water reabsorption into the blood.
