Transportation & Respiration

What does the circulatory system consist of?

What does the circulatory system consist of?

• Heart

• Blood vessels

• blood

• Lymph

• Lymphatic vessels

• glands

What does the circulatory system do?

the system circulates blood & lymph through the body

What does the respiratory system do?

a network of organs & tissues that help you breath

what does the respiratory system consists of?

• Airway

• lungs

• blood vessels

• Muscles that power your lungs

The things in the respiratory system work together for what?

work together to move 02 thought the body & clean out waste gases such as CO2

Blood components are?

• Plasma

• Buffy coat

• Red blood cells

4 main components?

• Plasma

• Red blood cells

• White blood cells

• Platelets

Plasma

• recovers injuries

• Distributes nutrients

• removes waste

• prevents infections Is a liquid component

Red blood cells

Carries O2 from lungs & CO2 is exhaled

White blood cells

Part of the immune system

• Protect from infections by attacking the unknown cells

Platelets

Small, colourless cell fragments

• forms clots & stops or prevents bleeding made in the bone marrow

Antigens

any substance that causes the body to make an immune response against that substance

Antibodies

a protein produced by the body's immune system when it detects harmful substances

What are the blood types

A + - B + - AB + - O + -

What is the most common blood type?

O +

What is the rarest blood type?

AB -

What blood type is a universal donor?

O -

What blood type can receive blood from any other blood type

AB +

What is Rhesus Factor

A protein that is present or absent on the surface of red blood cells. if is it there then the person is Rh + but if not than they are Rh -

What Rh is most common?

Rh +

Haemolytic anemia

Rh antibodies that attack the baby's red blood cells faster than it can make new ones

Rh immunoglobin

Protein that prevents the expecting mother from producing Rh antibodies

Factors that stop people from being able to donate blood?

• Being under 17

• Being pregnent

• Tattoo in the last 3 months

• under 110lbs

• HIV +

Blood Vessels

• Distributes blood through channels, to body tissues

• Vessels make up two closed systems of tubes that begin & end at the heart

What are the 2 closed systems & what are the different blood vessels?

The Pulmonary system & the systemic system

• Arteries

• Arterioles

• Capillaries

• Veins

• Venules

The Pulmonary System

Transports blood from heart to the lungs & back to the heart

The Systemic System

Carries blood from the heart to the tissues in all parts of the body & then returns the blood to the heart

Arteries

Blood vessels which carry blood away from the heart to various parts of the body

• Larger arteries branch into many tiny arteries

Largest Artery in the body?

Aorta

Smallest Artery in the body?

Arterioles

Veins

Blood vessels which carry blood to the heart from various parts of the body

What type of walls do veins have & why?

Walls are thinner & less rigid so that they can hold more blood

Cappilaries

They transport blood, nutrients and oxygen to cells in your organs and body systems

What type of walls do Capillaries

Has very thin walls, Arterioles branch into a network of capillaries.

What do the capillaries do?

Exchange between the blood & the cells of the body take place.

• The blood is gives up it's O2 & takes on CO2

Where do capillaries reunite?

venules which going to larger & larger veins

Venous Valves

The pumping action of the heart causes blood to be forced from the arteries to the capillaries

• Since veins work against gravity they have a pumping system to make sure the blood can make a return trip

Why do venous valves happen?

No idenified cause but could be if

• Old age

• Female

• over weight

• Genetics

Draw open and closed Venous valves

What is similar & different about antigens & antibodies

What antigens & antibodies do A Blood type have?

Anti A Compatible with: A & O Antibodies against: Anti B

What antigens & antibodies do B Blood type have?

Anti B Compatible with: B & O Antibodies against: Anti A

What antigens & antibodies do AB Blood type have?

Anti A & B Compatible with: A, B & O Antibodies against: none

What antigens & antibodies do O Blood type have?

No Antigens Compatible with: O Antibodies against: A & B

How does Rh factor effect pregnancy?

The mother is Rh - & the baby is Rh + therefore mother releases antigen d & will attack baby.

3 main blood vessels in the circulatory system?

• Arteries

• Veins

• Capillaries

What is diffusion & how does it relate to the circulatory system?

The movement of molecules from a high to low concentration. Diffusion is needed for the passing of O2 & the exchange of CO2
