Transport in Animals

This week we start to look at the circulatory, respiratory and excretory systems of animals and the xylem and phloem cells in plants. We know now how different organisms obtain their nutrients, now we need to know how nutrients and oxygen get to every cell in the body and how wastes are removed from it.

Great animation about how the heart works here. Video of heart and circulatory system here.

Human Anatomy Online – interactive diagrams of all the systems, including nervous, skeletal and reproductive. KLB Science Interactivities have produced a clever quiz on the heart and circulatory system. More great Human Body stuff from National Geographic here.

Don’t get confused between cellular respiration and breathing! Cellular respiration is the process that converts glucose and oxygen to energy within the cells. Oxygen is supplied to those cells by the red blood cells, which carry oxyhaemoglobin to cells and remove carbon dioxide from cells. The respiratory system includes the lungs, trachea, bronchioles and alveoli, which carry air into and out of the body.

During the two week break make sure you read through Chapter 5 and start answering the Chapter review questions. Take study notes, including definitions of key terms and important concepts. You could also draw concept maps for each of the digestive, respiratory, excretory and circulatory systems. Compare the nutrition and transport systems in plants and animals.
