Human Anatomy: RAA Reflex

Overview

We’ll study blood pressure today for 48 minutes.  Today’s lecture is all about the homeostasis of BP.

The kidney is an endocrine gland.  Almost every tissue in the body secretes hormones.  The kidney secretes renin, also epigen.

JG or juxta glomurular cells secrete renin.  Drop in BP, drop in sodium levels, increases in K+ levels all trigger renin release.

Renin acts on angiotensinogen, a protein in the blood made in the liver.  Angiotensin 1 is activated.  In the lungs, ACE makes AT1 into AT2.  Then angiotensin 2 is activated.  Finally aldosterone is activated after release from the adrenal gland.

Three things happen: K+ excreted, H2O retention, NaCl retention.  Blood plasma volume is expanded, raising BP.  More blood in the vessels increases the pressure in the veins.  If you lose blood, your BP drops.

The most important electrolytes are sodium Na+ and potassium K+.

-gen is the inactive form of a protein.  Pepsinogen is activated by HCl in the stomach.

ADH is made by the hypothalamus, stored/secreted from the pituitary.  Controls osmolarity of CSF.  Increases H2o retention.  Too little ADH leads to diabetes incipidus.

Normal BP is 120/80.  This is for the brachial artery.  High BP is 140/90.  20% of americans have BP. To assist, reduce stress/RAA reflex.

Primary BP has unknown causes, maybe atherosclerosis.  Renal HT is caused by hyperaldosteronism.

BP = CO x TPV

You can use drugs to stop any step of RAA relex loop.  The trend is to stop HT earlier in the cycle.

The skeleton is an endocrine gland.  Osteocalcium.  Helps control sugar levels.

Wind Speed Beaufort Category How to Judge the Wind
1-3 mph Light Air Smoke drifts. Wind cannot be felt.
4-7 mph Light Breeze Wind felt on face. Leaves rustle. Weather vanes move.
8-12 mph Gentle Breeze Leaves and twigs in motion. Light flags are extended.
13-18 mph Moderate Breeze Wind raises dust and loose papers. Small branches move. Flags flap.
19-24 mph Fresh Breeze Small trees in leaf sway slightly. Wavelets form on ponds and lakes.
25-31 mph Strong Breeze Large branches move. Telephone lines sing.
