Cardiovascular

Question 1

What are the three main parts that the cardiovascular system is made up of

Answer 1

Blood Vessels, Heart, Blood

Question 2

What is the Function of the Cardiovascular System

Answer 2

Carries nutrients, and oxygen, to cells, and waste and carbon dioxide away from cells

Question 3

What does The cardiovascular system contain

Answer 3

White blood cells

Question 4

What is Gas exchange

Answer 4

Its when Oxygen gets dropped of in cells, and waste is picked up

Question 5

What is diffusion

Answer 5

These nutrients and gases move by diffusion from an area of higher
concentration to an area of lower concentration.

Question 6

What is pulmonary Circulation

Answer 6

but in
reverse– wastes and CO2 get dropped off, and oxygen gets picked up.

Question 7

How many chambers are in the heart

Answer 7

4

Question 8

The Atria

Answer 8

Upper
Chambers (collect
blood)

Question 9

The Ventricles

Answer 9

Ventricles: Lower
Chambers (squeeze
blood out of heart)

Question 10

What are heart Valves

Answer 10

Are “doors” located between the
atria and ventricles inside the
heart
● Responsible for the lub-dub sound
of your heart beat

Question 11

What is the Function of the Heart Valves

Answer 11

Functions
1. Regulate the amount of blood that
goes into and out of the heart
2. Prevents backwards flow

Question 12

What are the three type of Blood vessels

Answer 12

1- Veins
2- Capilaries
3-Arteries

Question 13

What is the Function of the three type of blood vessels

Answer 13

1- Arteries: carry
blood AWAY from
the heart
2- Capillaries connect
arteries to veins and is
where gas exchange
(C02 - 02) takes place
3- Veins: carry
blood back
TOWARDS the
heart

Question 14

What is blood

Answer 14

Blood - is a type of
connective tissue
made up of 4

Question 15

What are the 4 components of Blood

Answer 15

1) Red blood cells
2) White blood cells
3) Platelets
4) Plasma

Question 16

Red Blood cells

Answer 16

RBC contain a protein called
hemoglobin, which makes them
red and allows oxygen to attach to
them when you inhale.
● Does not contain a nucleus
( Made in bone marrow )

Question 17

White blood cells

Answer 17

WBCs fight pathogens by
engulfing (digesting) or
releasing chemicals called
antibodies to help destroy
pathogens.
● They also keep you healthy by
engulfing dead or damaged
body cells.
● WBC are made in bone marrow
and in the lymphatic system
(lymph node)

Question 18

Platelets

Answer 18

Platelets are pieces of larger
cells found in bone marrow that
are released into the
bloodstream.
* Platelets produce chemicals that
react with proteins to form a net.
This net traps other blood cells to
form a blood clot/scab.

Question 19

Plasma

Answer 19

Plasma - The fluid part
of blood that is a
mixture of water, CO 2 ,
minerals, proteins,
salts, glucose, amino
acids, hormones, and
wastes like urea.

Question 20

What is one disese of the Cradiovascular System

Answer 20

Atherosclerosis (Heart Disease)-
Buildup of fats, cholesterol and other
substance on the artery walls.

Question 21

What is the Largest artery in the Human body

Answer 21

Aorta

Question 22

Where does Gas- exchange occur in the Circulatory system

Answer 22

Alveoli

Question 23

What is the function of the Vena Cava in the circulatory system

Answer 23

Carry deoxyginated blood back to the heart

Question 24

what describes the process of red blood cells delivering oxygen to body tissues

Answer 24

Diffusion

Question 25

Describe the path of deoxygenated and oxygenated blood starting and ending at the vena cava be sure to include when the blood flows to yhe body and lungs as well as when it passes a valve in the heart

Answer 25

Vena Cava → Right Atrium Blood from the body returns to the heart through the superior and inferior vena cava into the right atrium. Right Atrium → Tricuspid Valve → Right Ventricle Blood flows through the tricuspid valve into the right ventricle. Right Ventricle → Pulmonary Valve → Pulmonary Arteries When the right ventricle contracts, blood is pumped through the pulmonary valve into the pulmonary arteries, which carry it to the lungs. Lungs In the lungs, the blood releases carbon dioxide and picks up oxygen, becoming oxygenated. Pulmonary Veins → Left Atrium Oxygenated blood returns from the lungs to the heart via the pulmonary veins, entering the left atrium. Left Atrium → Bicuspid (Mitral) Valve → Left Ventricle Blood flows through the bicuspid (mitral) valve into the left ventricle. Left Ventricle → Aortic Valve → Aorta When the left ventricle contracts, it pumps blood through the aortic valve into the aorta, the body's main artery. Aorta → Body The aorta delivers oxygenated blood to the body, supplying organs and tissues. After delivering oxygen and picking up waste products, the blood becomes deoxygenated again. Deoxygenated blood returns to the heart through the vena cava, and the cycle starts over. Tricuspid valve (right atrium → right ventricle) Pulmonary valve (right ventricle → pulmonary arteries) Bicuspid/mitral valve (left atrium → left ventricle) Aortic valve (left ventricle → aorta)

Question 26

Explain the process of diffusion and gas exchange in the circulatory system

Answer 26

In the circulatory system, gas exchange happens through diffusion, where oxygen from the lungs enters the blood and carbon dioxide from the blood enters the lungs. This exchange occurs at the alveoli, which are tiny air sacs in the lungs. The thin walls of the alveoli and the capillaries (tiny blood vessels) allow for easy diffusion of gases.

Question 27

Which side of the Heart is oxygenated and which side is not

Answer 27

The left side of the heart receives and pumps oxygenated (oxygen-rich) blood, while the right side of the heart receives and pumps deoxygenated (oxygen-poor) blood

Question 28

Order of blood flow

Answer 28

1- Aorta 2. Pulmonary Artery 3. Pulmonary Vein 4. Left Atrium 5. Right
