White Bood Cells

White Blood Cells only estimate for 1% of our blood but they generate a tremendous influence on our immune system. White Blood Cells are also named leukocytes, they help with getting rid of bacteria and they defend us against microorganisms. White blood cells are always at conflict against infections, bacteria, and other foreign diseases that can be an immense threat to your health.

You can think of White Blood Cells as your immunisation cells because they enhance our immunity the more they are presented to new foreign viruses. While circulating throughout your body, white blood cells can always encounter viruses and bacterias and they confront it immediately and if a particular region of your body is in distress, white blood cells will hurry in to help defeat the threatening virus.

White blood cells are produced in your bone marrow, and because some white blood cells have a life span of 1-3 days, your bone marrow is continuously making them. There are 5 various types of white blood cells. Monocytes are White blood cells that have a greater lifespan than others and they also assist when fighting off bacteria, Lymphocytes are the once that generate antibodies against bacteria, viruses and other potentially lethal diseases, Neutrophils remove and absorb bacteria and they are the most numerous type of white blood cells when infection strikes, Basophils sound an alarm when infectious agents or viruses penetrate your blood, and Eosinophils eliminate parasites and cancer cells and they also help with allergic responses. 

Science - Heart Dissection

• What have we been learning about?

We have been learning about the Circulatory System and the different parts that make up our whole Circulatory System.

• Why are we dissecting a heart?

We directed a heart so we can see what the parts of the heart actually look like up-close and to understand how our hearts work more clearly while looking at it in real life.

• What are the parts of the heart? Did you see them?

The parts of the heart are:

Arteries - takes blood away from the heart.

Atrium - entryways where blood enters from each side of the heart, from the veins.

Valves - one-way gates, it only lets blood move in one direction. Helpful especially when pushing against gravity.

Heart Strings - Strong fibres that hold the valves in place.

Septum - separates the left and right side of the heart.

Veins - takes blood back to the heart.

Ventricles - V-shaped cavities which push the blood into arteries to take away from the heart.

Muscled walls - strong muscles to help squeeze and push the blood around the body. the left side of the heart has more muscles. 

I, unfortunately, didn't get to dissect a heart because I wasn't at school at the time that they did dissect the hearts. I was really sad that I couldn't get the chance to dissect and look at a heart up-close because I  really wanted to learn more about our hearts while also having the chance to the dissect one.
