BIOLOGY 7: Blood & The Circulatory System

HideShow resource information
What is blood made up of?
Cells (white & red), platelets and plasma
1 of 25
How does blood transport substances around the body?
Through the circulatory system. (Blood carries oxygen and glucose to the muscles and takes carbon dioxide, a waste product, away from them.)
2 of 25
What is the job of red blood cells?
To transport oxygen from the lungs to the rest of the body
3 of 25
What don't red blood cells have?
A nucleus
4 of 25
Why don't red blood cells have a nucleus?
So they can be packed with haemoglobin
5 of 25
What is haemoglobin?
A substance hat binds with oxygen
6 of 25
What shape are red blood cells?
Biconcave
7 of 25
Why are red blood cells biconcave in shape?
So they have a large surface area for exchanging oxygen
8 of 25
In which state is plasma?
Liquid
9 of 25
What is the job of plasma?
To carry nutrients (glucose &amino acids), antibodies. hormones and waste (urea and carbon dioxide)
10 of 25
What is the job of white blood cells?
To help fight infection and to protect your body against attack from microorganisms
11 of 25
What is the job of platelets?
To help the blood to clot at the site of a wound
12 of 25
What type of circulatory system do humans have?
A double circulatory system
13 of 25
What is a double circulatory system?
Two circuits joined together
14 of 25
What do the two different circuits (in the circulatory system) do?
1) One pumps de-oxygenated blood to the lungs, so they can get oxygen. The blood returns to the heart. 2) The other pumps oxygenated blood around the body. The blood gives its oxygen to body cells and the de-oxygenated blood returns to the heart
15 of 25
Which is the left side of the heart, and which is the right?
They are opposite (right side of the heart is left on the picture)
16 of 25
What does the right atrium receive and how?
It receives de-oxygenated blood from the body, through the vena cava
17 of 25
Which side of the heart pumps blood to the lungs?
The right side
18 of 25
Which side of the heart pumps blood to the rest of the body?
The left side
19 of 25
Why is the wall of the left ventricle thicker than the wall of the right ventricle?
It has to pump blood around the whole body, not just to the lungs
20 of 25
Where does the blood go once it has entered the atrium?
The left or right ventricle
21 of 25
How does blood leave the right ventricle?
Through the pulmonary artery
22 of 25
How does oxygenated blood leave the left ventricle?
Through the aorta
23 of 25
How does the left atrium receive blood?
Through the pulmonary vein
24 of 25
What is the role of valves?
They prevent the back flow of blood

good revision notes

great notes

Swallowtail

A useful set of flashcards on the circulatory system  which would be helpful for any student studying this topic. Check your specification carefully to see exactly which names of vessels and parts of the heart need to be known for your specification as they do differ.

Excellent - very helpful thanks

I think that this is probably my lifesaver... don't you think?? I mean it's my GCSE's and I have to be revising so what better thing is there than this??

Imogen is a ******* *** hole! LoL

this notes are a F U C K I N G  C U N T what the F U C K is wrong
