What determines if a heart is left or right dominant? |
Where or not the RCA (via the PDA) supplies the inferior Left ventricle. (Right dominat 80%) (if Left dominant, then its Circumflex, from LCA, that supplies the inferior left vent) |
|

Left Circumflex Artery (LCX) |
|

|
The adrenal cortex came from mesoderm, where did the medulla come from? |
Medulla of adrenal context is derived from Neural Crest (medulla) |
|

What absorbs iodine from the blood in the Thyroid and what is done with the iodine? |
the Follicular (epithelial) cells absorb I from the blood and make it into colloid aka Thyroglobulin. Which is stored until the hypothal sends out TSH which stimulates the thread to make T3 and T4 from the Thyroglobulin, aka colloid. |

|
|

Actin filaments |
|
|
How do lipids enter blood stream vs proteins/carbs? |
Lipids- DIFFUSE into LACTEALS and THORACIC DUCT as CHILOMICRONS and enter the blood stream at SUBCLAVIAN VEIN Proteins/Carbs: Usually Na-Cotransport into portal system--1st pass effect. |
|
|
Which carbohydrate does NOT use Na cotransport for absorption like the others, and what does it use? |
