Question 5

Question 6

The cardiovascular system includes:

Answer 6

Blood
Blood vessels
The heart

Question 7

Blood vessels are divided in 3

Answer 7

Arteries
Capillaries
Veins

Question 8

Arteries

Answer 8

Blood vessel that carries blood from heart to other parts of the body
They r the largest
Thick walls to withstand high pressure

Question 9

Capillaries

Answer 9

Blood vessel with a small diameter and AND very thin walls in which exchanges between the blood and the cells of organs can occur

• smallest blood vessels
• move in single file line
• their walls are made form a single layer of cells

Question 10

Veins

Answer 10

A blood vessel that carries blood back to the heart

• once the capillaries have passed the organs they reunite to form veins
• pressure inside the veins is very low and they need muscular contractions to move the blood
• veins in our lower body also have valves so that blood can flow downwards

Question 11

The four chambers

Answer 11

• right atrium
• left atrium
• right ventricle
• left ventricle

Question 12

What would happen without the heart

Answer 12

Blood would not circulate throughout the body

Question 13

Valves

Answer 13

To make blood. Don’t go backwards

Question 14

Pulmonary artery

Answer 14

Brings c02 rich blood to th slung

Question 15

Pulmonary vein

Answer 15

Brings 02 vrich blood back to the heart

Question 16

Aorta

Answer 16

Distributes o2 rich blood to the entire body

Question 17

Why is the heart a double pump

Answer 17

It simotaniously pump both sides of the heart

Question 18

Pulmonary circulation

Answer 18

• right side of heart
• short
• rich in co2
• blood exits the right ventricle and goes to lungs through pulmonary artery. It exchanges co2 for o2 in the capillaries of the lungs and returns to the left atrium through the pulmonary vein

Question 19

Systemic circulation

Answer 19

• left side
• longer (goes through whole body)
• rich in o2
• blood exits the left ventricle through aorta which divides into arteries that go to the capillaries of the various organs. Gets rid of o2, nutrients and other substances and picks up co2. Then it goes back to the heart and goes into the right atrium through the vena cava.

Question 20

Plasma

Answer 20

Yellowish liquid made of 90% r
I.T contains: nutrients, antibodies, hormones, and waste from cellular activity

• transports nutrients to cells
• transports waste des form cellular activity to excretatory
• transports hormones, antibody, proteins, and others

Answer 26

AB+ can receive from anyone

Question 27

Diastole

Answer 27

Filling phase of the heart it Filled my day hase of the heart
I.T is resting, the muscles are relaxed and blood flows through the atria

Question 28

Systole

Answer 28

The contraction phase
The atria contracts at exactly the same time pushing the blood into the ventricles a tenth of a second later the ventricles contrat forcing the blood into the arteries
