Core 2: CQ1 P4

Question 1

Cardiovascular system

Answer 1

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

Question 2

Blood types

Answer 2

Dark red- oxygen poor

Scarlet red- oxygen rich

Question 3

Blood functions

Answer 3

• 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

Question 4

Plasma

Answer 4

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

Question 5

How can plasma be affected

Answer 5

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)

Question 6

Erythrocytes

Answer 6

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

Question 7

Leucocytes

Answer 7

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

Question 8

Thrombocytes

Answer 8

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

Question 9

Average heart rate adult resting

Answer 9

70-80bpm

Question 10

Ventricles

Answer 10

Thicker and bigger

Responsible for propelling blood from heart into circulation around body

Question 11

Chambers of heart

Answer 11

Superior- right and left atrium (upper)

Inferior- left and right ventricle (lower)

Question 12

Valves

Answer 12

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

Question 13

Atria

Answer 13

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

Question 14

Immediate response to exercise

Answer 14

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

Question 15

Long term adaptions yo aerobic exercise

Answer 15

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