THE STRUCTURE OF BLOOD VESSELS & BLOOD DISTRIBUTION (SOC 15, 16 & 17)

Question 1

CARDIOVASCULAR MEANING AND FUNCTIONS?:

Answer 1

Cardio= Heart
Vascular= Blood Vessels

Question 2

STEP 1?:

Answer 2

It transport Oxygen, Carbon Dioxide and Nutrients. The heart pumps out oxygen which releases energy stored as glucose in cells. Carbon dioxide gets released out of the body by doing cardiovascular fitness.

Question 3

STEP 2?:

Answer 3

Platelets help Clot The Blood if you have a cut, forms a scab to stop bleeding and heals the wound.

Question 4

STEP 3?:

Answer 4

It controls the Body’s Temperature.

Question 5

WHAT DOES EXERCISE GOT TO DO WITH YOUR CARDIOVASCULAR SYSTEM?:

Answer 5

Exercises makes your body work harder. Your muscles require oxygen, which means your body needs more oxygen and nutrients, glucose to function.

Question 6

WHAT HAPPENS TO YOUR BODY WHEN ADRENALINE APPEARS?:

Answer 6

When your body heart rate changes, then adrenaline increases. Adrenaline is a hormone, makes the heart pump quicker. Exercise… Stressful situations…

Question 7

WHAT IS THE HEART?, HOW IS IT FORMED?:

Answer 7

The Heart is a muscular pump, has four chambers, atria collects the blood as it comes into the heart, ventricles that pump the blood out of the heart. Valves between the atria and the ventricles make sure that the blood cannot flow backwards due to a heart attack.

Question 8

HOW BLOOD FROM THE HEART IS TRANSFERRED TO THE REST OF THE BODY?:

Answer 8

Blood from the ventricles has to go right round the body. Blood from ventricles has to reach the lungs, which is thinner. Doctors can open up our blood vessels by going on medication after a recent health problem/s.

Question 9

THE FORMATION OF THE HEART & HOW THE BODY USES EACH PART…?:

Answer 9

The Heart is divided into two parts. The right side pumps deoxygenated blood, this is so the lungs pick it all up. The rest of the body is pumped around with pxygenated blood.

Question 10

VENA CAVA?:

Answer 10

The Vena Cava brings venous (deoxygenated blood) body from the body to the right atrium, where it collects.

Question 11

WHAT IS THE JOB OF THE VENOUS BLOOD IN THE HEART/BODY?:

Answer 11

The Venous Blood passes from the right atrium to the right ventricle through a valve with three cusps, called the tricuspid valve.

Question 12

WHAT IS THE FUNCTIONS OF THE BLOOD WHEN CARRYING BLOOD AROUND THE BODY?:

Answer 12

The Blood then passes through the pulmonary valve into the pulmonary artery, and on into the lungs where it will pick up oxygen.

Passes into the left ventricle through a valve with two cusps, the bicuspid.

Question 13

WHAT IS THE JOB OF OXYGENATED BLOOD IN THE BODY?, & HOW DOES IT WORK IN THE BODY?, WHERE IS IT LOCATED?:

Answer 13

Oxygenated Blood returns to the heart through pulmonary vein and collects in the left atrium.

Oxygenated Blood passes through the aortic valve and is ready to be sent round the body, through artery called aorta.

Question 14

HOW THE HEART PUMPS?:

Answer 14

The Heart fills itself with oxygenated blood and is a repeated process, opening & closing & is supplying blood to our organs.

Question 15

WHAT IS THE SECOND PHASE OF HOW THE HEART PUMPS?:

Answer 15

Second Phase is when the Heart relaxes, called ‘diastole’, heart re-filles with blood. The ventricles are filling and relaxing, while the atria are just relaxing. More oxygenated blood requires for respiration.

Question 16

WHAT IS THE DEFINITION OF BLOOD PRESSURE?:

Answer 16

Blood Pressure is a measure of force that your heart uses to pump the blood round your body. In sport it/you will have a higher problems in the future. An example of this would be 135/95. The top number is your systolic blood pressure, however the bottom number is your diastolic blood pressure, the lowest pressure, when your heart is relaxing.

Question 17

HOW DO ARTERIES, VEINS & CAPILLARIES HELP DURING PHYSICAL ACTIVITY?:

Answer 17

During exercise or Physical Activity the arteries, veins and capillaries work together to supply your muscles with the oxygen they need to work, this is so de-oxygenated blood is carried back to the heart & is provided by the muscles from oxygenated blood. The three main stages of blood vessels are different.

Question 18

WHAT IS THE IMPORTANCE OF A ARTERY?:

Answer 18

An Artery is a blood vessel taking blood away from the heart, carries oxygenated blood and is a vessel.

Question 19

WHAT IS THE IMPORTANCE OF A VEIN?:

Answer 19

A Vein is a vessel carrying de-oxygenated blood back to the heart to re-gain oxygen.

Question 20

WHAT IS THE IMPORTANCE OF CAPILLARIES?:

Answer 20

Capillaries are microscopic vessels - just one cell thick - that link arteries with veins, blood pressure in capillaries is very low. They need to be thinner due to the transport.

Question 21

WHAT IS VASCULAR SHUNTING?, WHAT ARE THE FUNCTIONS?:

Answer 21

When exercising, the distribution of blood in your body changes. Your muscles need more blood of movement. This process is called Vascular Shunting.

Question 22

WHAT ARE RED BLOOD CELLS?, WHAT ARE THE FUNCTIONS?:

Answer 22

Red Blood Cells transport oxygen from the lungs to the body’s cells, they contain haemoglobin, stores oxygen & carbon dioxide. This is important for long distance runners.

Question 23

WHAT ARE WHITE BLOOD CELLS?, WHAT ARE THE FUNCTIONS?:

Answer 23

White Blood Cells kill diseases & pathogens. They produce anti-bodies. This is bad though, especially if you have an illness or injury which means you cannot perform. This could lead to reversibility etc.

Question 24

WHAT ARE THE IMPORTANCE OF PLATELETS?, WHAT ARE THE FUNCTIONS?:

Answer 24

Platelets clot the blood due to a cut in the skin which carry white blood cells to help not just to clot but also hold the skin back together. They help stick (Hold) back together to form a scar later.

Question 25

WHAT IS THE IMPORTANCE OF BLOOD PLASMA?, WHAT ARE THE FUNCTIONS?:

Answer 25

Blood Plasma is important in sport because without circulation between the cells and tissues, oxygen transportation cannot happen - this/This means muscle cannot get energy, they need to work. Carbon Dioxide dissolve in blood when leaving the body. This contains a range of substances. Plasma is a pale straw - coloured liquid made up of 90% water mostly.
