Lymphatic system, respiratory system,circulatory system Flashcards

1
Q

The function of the respiratory system is?

A

The function is to transport air to the lungs & facilitates the diffusion of O2 into the the bloodstream. It recieves waste from the blood & exhales it (carbon dioxide)

Q

What does the upper airway provide?

A

provides a passage for air to enter & leave the body. It warms, humitifies and cleans the air & guides it into the lower airway. It consists of the nasal cavitiy the pharnx & larynx.

Q

The Lower airway is part of?…

A

is part of the respiratory tract. -they are branching, hollow passageways that conduct air to & from the aveoli. -All passageways in the lower tract can alter in diameter, this allows them to regulate the speed at which the air flows through.

Q

Pharynx is?

A

(throat) divides into 2 parts: trachea-wind pipe and esophagus (food pipe). There is a esmall flap of cartilage. Called the Epiglottis, this prevents the food from going in the trachea.

Q

If the lymphatic system didn’t drain excess fluid from the tissue what would happen?

A

the lymph fluid would build up & the tissue would swell.

21
Q

Major parts of lymph tissue are located where?

A

in the bone marrow, spleen, thymus gland, lymph nodes, & tonsils.

22
Q

Lymph nodes produce immune cells called?

A

T-cells and B-cells

23
Q

What do T-cells and B-cells do?

A

These help the body fight infection, they also filter fluid & remove foreign material such as bacteria & cancer cells. They become swollen from conditions like infection, abscess’s or cancer.

24
Q

Common areas where Lymph nodes are felt are?

A

groin, armpit, behind the ears, & sides of neck

25
Q

The Lymphatic system does what?

A

collects the fluid & returns it to the circulatory system

26
Q

Functions of the Lymphatic system?

What happens as blood moves through arteries and veins?

A

fluids & protein balance as blood moves through the arteries & veins, 10% of the fluid becomes trapped in the tissues. This loss of fluid could be life threatening. (10%= 1-2 L per day).

27
Q

The Lymphatic systems organs consist of?

A

Lymphnodes, ducts and vessels.

28
Q

Lymphnodes, ducts and vessels produce and transport what?

A

They produce & transport lymph from tissue to the bloodstream. It’s a mojor component of the body’s immune system.

29
Q

The network of vessels & nodes transports & filters what?

A

lymph fluid.

30
Q

lymph vessels in the lining of the GI tract absorb what?

A

fat from foods

31
Q

The primary function of the respiratory system is to?

A

supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body

32
Q

The circulatory system is?

A

is an organ system that passes nutrients (amino acids, electrolytes &lymph), horomones, blood cells to and from cells in the body & uses them to help fight disease, stabilize body temp & pH.

33
Q

The circulatory system is divided into three major parts, what are they?

A

1) Heart- is located in the center of your chest slightly to the left. It’s job is to pump your blood & keep the blood moving through out the body. 2)The blood- is pumped by your heart, carries nutrients, H20,0z & waste to& from your cells. Its made up of liquid, solids &0z & carbon dioxide.
3) Blood vessels- 1)arteries- carry O2 rich blood away from the heart 2)veins carry deoxygenated blood back to your heart.3)Capillaries- tiny blood vessels that connect arteries to veins. Nutrients, waste, O2, pass in &out of your blood through the capillary walls.

34
Q

RBC are called? and responsible for what?

A

erythrocytes- are responsible for carrying oxygen & carbon dioxide.

35
Q

What do red blood cells do?

A

RBC pick up O2 & delivers it to the cells, then fills up with carbon dioxide & brings it back to the lungswhere we exhale.

36
Q

How many RBC are in a single drop of blood?

A

There are 5 million red blood cells in a drop of blood.

37
Q

WBC are called? and do what?

A

leukocytes, help to fight infection.-attack & destroy germs when they enter the body.
-you will provide more WBC when you have an infection

38
Q

What are platelets?

A

blood cells that help stop bleeding.

they form a scab, they are sticky.

39
Q

Plasma is?

A

liquid part of the blood, 1/2 your blood is made of plasma it’s made in the liver.

40
Q

The heart is what and what size?

A

a muscle about the size of your fist.

-sends the blood around your body -is like 2 pumps

41
Q

The right side of your heart does what?

A

receives blood from the body & pumps it to your lungs

42
Q

The lt side of your heart does what?

A

recieves blood from the lungs and pumps it to the body.

43
Q

Before each beat, your heart?

A

fills with blood, when it contracts (squeezes) it pushes the blood out.

44
Q

There are four diffrent chambers on the heart, what are the top two called?

A

top 2 chambers are called atria. Artia are the chambers that fill with blood returning from the body & lungs.

45
Q

There are four chambers on the heart, what are the bottom two called?

A

2 bottom chambers are called ventricles. They send the blood out to the body & lungs.

46
Q

Running down the middle of the heart is a thick wall of muscle called?

A

a spetum,seperates lt side from rt side. atria is two and artia is one.

47
Q

The atria fill with blood and posh it where?

A

push it to the ventricles. The ventricles squeeze the blood out of the heart.

48
Q

Mitral valve & tricuspid valves do what?

A

valves let the blodd flow from the atria to the ventricles.

49
Q

aortic valve and pulmonary valve control the flow of ?

A

blood leaving the heart & close quickly to prevent blood from flowing backwards
