Name 5 functions of the Cardiorespiratory system |
- To carry oxygen to cells and collect carbon dioxide - To carry nutrients from the Small Intestine - To pick up oxygen from the lungs - To carry nutrients to cells and collect waste - To carry hormones and other signalling substances - Thermoregulation |
|
|
What are the 2 circuits of the Cardiorespiratory system? |
- Pulmonary Circuit - Systemic Circuit |
|
|
What does the Systemic Circuit do? |
moves blood to and from Capillaires at cells |
|
|
