Question

Cause and Effect :

Answer 1

Answer:

The thyroid gland produces thyroxine (referred to as T4), which is a relatively inactive prohormone. The highly active hormone is triiodothyronine (referred to as T3).

Key actions of adrenaline include increasing the heart rate, increasing blood pressure, expanding the air passages of the lungs, enlarging the pupil in the eye (see photo), redistributing blood to the muscles and altering the body's metabolism, so as to maximise blood glucose levels (primarily for the brain).

Answer 2

Cause: Thyroid produces hormones

Effect: Cells produce thyroxine and triiodothyronine and release them into the bloodstream.

Cause: Adrenal produces adrenaline.

Effect: The adrenaline is released into the bloodstream creating an almost immediate reaction by your organs.
