B2-Blood

Question 1

What happens on the right hand side of the heart?

Answer 1

1) This is (indicated in blue) receives de-oxygenated blood from the tissues(via the vena cava) into the right atrium.
2) The de-oxygenated blood is forced through the tricuspid valves into right ventricle
3) Then is finally the blood is pumped is forced under high pressure out of the right ventricle to the lungs via pulmonary artery

Question 2

What happens on the left side of the heart?

Answer 2

This side of the heart receives the oxygenated blood from the lungs via the pulmonary veins into the left atrium
2)The oxygenated blood passes through the bicuspid valves into the left ventricle. Then pumped to the aorta under greater pressure

Question 3

What is the Cardiac cycle

Answer 3

The circulation of blood through heart in every heart beat.

Question 4

What is the order of cardiac Cycle

Answer 4

1) De-oxygenated blood come from Superior Vena cava
2) Right atrium to Tricuspid valve
3) Right ventricle to pulmonary veins
4) Pulmonary artery to the lungs
5) Then gas exchange happens in lungs.
6) Oxygenated blood is carried through pulmonary veins
7) The to left atrium
8) Then to the aortic valve
9) Left ventricle
10) Pumped out of heart out of the aortic valve

Question 5

Why is it important for blood to be pumped around the body?

Answer 5

1) It carries oxygen
2) Removes the waste products of respiration
3) Distributes heat around the body
4) Transports hormones, Nutrients, salts and enzymes

Question 6

Blood?

Answer 6

Blood is composed of different cell types suspended in a fluid called plasma

Question 7

What is Anaemia?

Answer 7

Anaemia is the result of not having enough red blood cells to take oxygen around the body or having a fault red blood cells that are unable to carry enough oxygen.

Question 8

Causes of Anaemia?

Answer 8

1) Shortage of irons or vitamins
2) Cancer
3) Anaemia due to excessive destruction of red blood cells

Question 9

Signs of symptoms of Anaemia?

Answer 9

1) Fatigue or tiredness
2) Dizziness
3) Fast or irregular heartbeat
4) Heart ache

Question 10

Stroke?

Answer 10

A stroke is a brain attack .It happens when the blood supply to part of the brain is cut off, killing brain cells

Question 11

Symptoms Of Stroke

Answer 11

1) Sudden weakness or numbness
2) Difficulty finding words
3) Sudden blurred vision or loss of sight
4) memory loss

Question 12

Cause of stroke

Answer 12

As we age our arteries become harder and narrower which makes it more likely to be blocked. But can also be caused by lifestyle factors which can speed process of stroke

Question 13

What are the three different types of stroke

Answer 13

1) An ischaemic stroke caused by blockage cutting off blood supply to the brain
2) A haemorrhagic stroke caused by bleeding in or around the brain
3) A transient ischaemic attack or TIA known as mini stroke this is a blockage that stops blood getting into the brain which is temporary

Question 14

What is hypertension?

Answer 14

High blood [pressure is medically known as hypertension it mean when the blood pressure is too high which means our heart work harder to pump blood around the body. This can lead to heart failure, heart attacks, strokes and vascular dementia

Question 15

What is normal blood pressure

Answer 15

Systolic lower than 140 mmHg

20Diastolic:Lower than 90mmHg

Question 16

What is Low blood pressure

Answer 16

1) Systolic lower than 90mmHg

2) Diastolic Lower than 60mmHg

Question 17

What is possible hypertension?

Answer 17

1) Systolic: between 140 and 180 mmHg

2) Diastolic: Between 90 and 110 mmHg

Question 18

What is coronary heart Disease(CHD)

Answer 18

Coronary heart disease is the term used to describe what happens when your heart’s blood supply is interrupted by a build of fatty substances in the coronary arteries

Question 19

Symptoms of CHD

Answer 19

1)Chest pains
2)Shortness of breath
3)Pain throughout the body
4Feeling faint

Question 20

What does Systolic blood pressure mean

Answer 20

Systolic BP is the pressure of blood of when the ventricle are contacting

Question 21

What is Diastolic BP

Answer 21

The pressure of blood when the ventricles are relaxed and filled

Question 22

What is the order of blood when its goes through blood vessels?

Answer 22

1) Aorta is the largest blood vessel carries oxygenated
2) Many major arteries branch off the aorta to supply different area of the body with 02
2) Arteries lead to smaller blood vessels called arterioles which deliver blood to the capillaries in the body organ and tissues
3) Capillaries supply the cells and tissue with nutrients from the blood
4) Capillaries unit arterioles and venules in the cells and tissue
