The new topic in Biology is the Endocrine System and we were to do the activities on Male’s blog:
- Hormone: chemical substance produced by a gland, carried by the blood, which alters the activity of one or more specific target organs.
- Search in the internet a picture which shows the glands which secrete hormones in the human body.
What hormones secrete each gland:
Adrenal gland: Adrenaline
Thyroid gland: Thyroxine and calcitonin
Pituitary gland: Growth hormone
Pineal gland: Melatonin
3. ADRENALINE. State the effects of adrenaline. Chose a picture which shows a situation in which adrenaline is secreted. Explain.
Adrenaline is when you are frightened, excited or keyed up. There your brain sends impulses along a nerve to your adrenal glands, and these secrete adrenaline into the blood. The main effects of adrenaline are: Your hearts beats faster, your breathing rate increases, your pain body’s ability decreases and it causes a noticeable increase in strength and performance.
