Transport in humans

A multicellular organisms , such as a person,  needs a transport system to move substances around the cells. In the human body, a transport system consists of:

  • The heart
  • Blood vessels: arteries, veins and capillaries
  • Blood: components and functions

 

The heart and circulation

  • Read pages 4 and 5 from THIS LINK and play the animations.
  • How does the heart work? Watch the video!

  • INVESTIGATING HEART DISEASE: click on THIS LINK to learn about the angiogram and the ECG.

Blood vessels

  • Let´s learn more about arteries, veins and capillaries.

The structure of each of them is related to the function.

READ HERE!

Blood

  • Take a look at the worksheet we did in class and click on THIS link!

Enjoy! 🙂

Biology Virtual Period: chromosomes and mitosis

CHROMOSOMES

In this period we are going to learn about the continuity of life. You may have heard words like DNA, genes, inheritance, chromosomes, cell division…. let´s investigate what all these is about!

Watch the video !

Activities:

1- a- Make a drawing of a body cell which contains one chromosome.

b- Make a drawing of a body cell which contains one chromosome before cell division.

Explain the difference between them.

2- Explain the difference in the number of chromosomes between a body cell and a gamete.

CELL DIVISION: MITOSIS

Watch THIS video about mitosis.

1- Make a drawing of a cell with 2 chromosomes.

2- Make a drawing of the same cell before cell division.

3. Make a drawing of the daughter cells.

4- Name examples in which mitosis takes place in the human body.
