1.control system,the receptors,the neurones,central nervous system,the nervous system.

2.Motor neurones : carry signals from the CNS to effectors.

Sensory neurones: carry signals from receptors to the spinal cord and brain.

Relay neurones:carry messages from one part of the CNS to another.

Endocrine System

In our biology class we have been studying the endocrine system.

We had to prepare an activity in our blogs. I worked with Agostina Alday.

  1. Define HORMONE: a chemical substance produced by a gland, carried by the blood, which alters the activity of one or more specific target organs.
  2. Glands which secrete hormones in the human body

ADRENALINE

Effects:

  • Heart beats faster, supplying oxygen to your brain and muscles more quickly, which gives them more energy for fighting or running away.
  • Increases breathing rate, more oxygen can enter the blood in the lungs.
  • Blood vessels in the skin and digestive system contract so that they carry very little blood. Makes you go pale.
  • Pupils in the eye widen, more light is allowed into the eye which might help you see more clearly.
  • Liver releases glucose for the muscles so that they can release energy for contracting.

ADRENALINE

In the image above a man is riding a unicycle on the peak of a cliff. This is a very risky situation because if you lost the balance you would fall from a very high height.

 

“Soldier,Rest”

In our Literature class  we have been analysing different poems.Here is the poem I had analysed with Lucia Roggero and Agostina Alday.
