1

Cardiovascular system

Delivers oxygen and nutrients to the cells, and removed waste from cells and maintains the balance of water in the body

Responsible for transporting the materials required by muscles to produce contraction, force and action

2

Blood types

Dark red- oxygen poor
Scarlet red- oxygen rich

3

Blood functions

-Transportation of O2 and nutrients to tissues and removes CO2 and waste
-Protection of the body via immune system and by clotting to prevent blood loss
- Regulation of body's temperature and fluid content of the body's tissue

4

Plasma

90% water- straw coloured liquid
Contains plasma proteins, nutrients, hormones, mineral salts and waste- all necessary for nourishment and functioning of tissue

5

How can plasma be affected

To much sweating and no fluid replacement results in water bring lost from the plasma
Increased the strain on circulatory system ( water needs to be replaced to maintain blood volume)

6

Erythrocytes

Red blood cells in bone marrow
Carries oxygen and carbon dioxide around body
Contains iron and haemoglobin and combines with oxygen and carries it from lungs to cells
Women have a reduced ability to carry O2 in their blood- Impacts on VO2 MAX

7

Leucocytes

White blood cells
Formed in bone marrow and lymph nodes
Provides body with a mobile protection system against disease

Changes shape and moved against blood flow to area of infection and disease

8

Thrombocytes

Platelets
Frigments of cells found in blood she are responsible for clotting
No nucleus

9

Average heart rate adult resting

70-80bpm

10

Ventricles

Thicker and bigger
Responsible for propelling blood from heart into circulation around body

11

Chambers of heart

Superior- right and left atrium (upper)
Inferior- left and right ventricle (lower)

12

Valves

Prevent the back flow of blood by opening and shutting them heart contracts and relaxes

13

Atria

Receive blood coming back into the heart
Right: receives oxygen poor blood via vena cava
Left: receives oxygen rich blood from lungs via pulmonary veins

14

Immediate response to exercise

⏫heart rate
⏫stroke volume
⏫cardiac output
⏫redistribution of blood flow- more to working muscles
⏫VO2

15

Long term adaptions yo aerobic exercise

⏬resting heart rate
⏫stroke volume
⏫cardiac output
⏬resistance to blood flow
⏫VO2 Max
⏫total blood volume
Stronger more efficient heart

16

Movement of blood

Lungs
Pulmonary vein
Left atrium
Left ventricle
Aorta
Arteries
Capillaries
Muscles/cells (exchange takes place)
Capillaries
Venules
Veins
Vena cava
Right atrium
Right ventricle
Pulmonary artery
Lungs

17

Circulatory system

Blood
Heart
Blood vessels
