Flashcards in Topic 8 - Exchange And Transport In Animals Deck (19):
1

What the equation for cardiac output

Stroke volume X heart rate

2

What's the system called for the right side of the heart

The pulmonary circuit

3

What's the circuit called from the heart to the body

The systemic system

4

What vein and artery go to and from the lungs

The pulmonary artery and pulmonary vein

5

What vein and artary go from the heart to the body and back

The aorta and Vena cava

6

What's the chemical equation for aerobic respiration

C6H12O6 + 6O2 ----- 6CO2 - 6H2O

7

Why does aerobic respiration release a great deal of energy

Because the glucose is fully oxidised

8

Why does anaerobic respiration not release a great deal of energy

Because the glucose is not fully oxidised

9

What's the formula for anaerobic respiration

Glucose ---- lactic acid

10

Name the 3 ways red blood cells are adapted to their function

Bi-concave digits for large surface area
Contain haemoblobin to form oxohaemoglobin
Have no nucleus to contain more haemoglobin

11

Name the 3 ways that white blood cells fight infection

1. Ingest pathogens
2. Produce antibodies that combine with antigens
3. Produce anti-toxins that stop toxins harming us

12

Define homeostasis

Keeping the internal conditions of the body constant

13

What is urea

Urea is a liquid formed by the break down of amino acids in the liver

14

How is blood urea and ions controlled

Capillaries filter out excess ions and urea out the blood and send them into the kidneys

15

How are ions and urea removed from the body

By wee

16

What kind of reaction is celleur respiration and why

Exothermic because it is continuously giving out energy

17

How are capillaries and alvioli adapted for their job

1 cell thick with large surface area for efficient gas exchange

18

How are veins adapted to their job

Think walls and contain valves to prevent backflow of blood at their low pressure

19

How are arteries adapted to their function

Have thick muscular walls to cope with high blood pressure being pumped from the lungs
