ashmedicus:

Renin is released by the juxtaglomerular apparatus in response to low blood volume. Renin meets with angiotensinogen, synthesized in the liver, and converts it to angiotensin I. Angiotensin I travels to the lungs where angiotensin converting enzyme (ACE) converts it to angiotensin II.
Angiotensin II is a vasoconstrictor which raises blood pressure, and it stimulates the release of aldosterone which causes the kidneys to reabsorb water and sodium, therefore raising blood pressure.
Always remember this. Forever.

Systemic Lupus Erythematosus

medicalstate:

A diagnostic criteria for SLE is to fulfill at least four of the following eleven letters that make up the mnemonic “SOAP BRAIN MD”:

  • Serositis
  • Oral ulcers
  • Arthritis
  • Photosensitivity
  • Blood disorders
  • Renal disease
  • Anti-nuclear antibody positive
  • Immunologic abnormalities
  • Neurologic disease
  • Malar rash
  • Discoid rash

That is a lot of ground to cover. Are you sure it is not lupus, House?


Never Let Monkeys Eat Bananas

Ranking the order of a normal differential count for white blood cells:

  • Neutrophils (60-70%)
  • Lymphocytes (20-40%)
  • Monocytes (3-10%)
  • Eosinophils (1-4%)
  • Basophils (~1%)

annesamb:

The heart pumps oxygenated blood to the body and deoxygenated blood to the lungs. In the human heart there is one atrium and one ventricle for each circulation, and with both a systemic and a pulmonary circulation there are four chambers in total: left atrium, left ventricle, right atrium and right ventricle.  The right atrium is the upper chamber of the right side of the heart.  The blood that is returned to the right atrium is deoxygenated (poor in  oxygen) and passed into the right ventricle to be pumped through the  pulmonary artery to the lungs for re-oxygenation and removal of carbon  dioxide. The left atrium receives newly oxygenated blood from the lungs  as well as the pulmonary vein which is passed into the strong left  ventricle to be pumped through the aorta to the different organs of the  body.
