Answer 12

Capillary beds

Question 13

What are capillary beds

Answer 13

A intertwined network of capillaries that supply an organ( ex the beds in the digestive system are open after eating so the capillaries can pick up nutrients) open means blood is flowing

Where is the the subclavian and what is it

Answer 14

It is near the shoulder and it a major artery

Question 15

Where and what are jugular veins

Answer 15

They are part of the major arteries and are in the neck and take blood from the head to the heart

Question 16

What are where are the carotid arteries

Answer 16

They are arteries that supple the head with oxygenated blood and are in and around the neck

Question 17

What are the mesenteric arteries

Answer 17

They supple blood to the intestines

Question 18

Anterior and posterior vena cava

Answer 18

The anterior delivers deoxygenated blood from higher parts of the body to the right side of the heart. The posterior carries deoxygenated blood from lower parts of the body into the right atrium

Question 19

Pulmonary veins/ arteries

Answer 19

Arteries carry oxygenated from heart to lungs. Veins bring blood from lungs to heart

Question 20

Hepatic portal vein

Answer 20

Gets blood from small intestine and goes to liver

Question 21

Hepatic vein

Answer 21

delivers blood from liver to heart

Question 22

Renal arteries/ veins

Answer 22

Veins carry blood from kidney to posterior vena cava (heart). Arteries carry blood from heart to kidneys

Question 23

Aorta

Answer 23

Top of left ventricle and delivers oxygenated blood to the body

Question 24

What are capillaries

Answer 24

They are the smallest blood vessels

Question 25

What do capillaries do

Answer 25

They are responsible for nutrients and waste exchange.( nutrients and oxygen delivered, co2 and waste removed)

Question 26

Veins

Answer 26

Move blood towards heart (usually deoxygenated)

Question 27

Venules

Answer 27

They are small veins that receive blood from capillaries

Question 28

Do veins have valves

Answer 28

Yes to stop back flow

Question 29

What helps blood move back to the heart

Answer 29

Muscle contractions

Question 30

How are capillaries, venules and veins connected

Answer 30

Capillaries join to make venules which join yo make veins

Question 31

Why happens when arteries age

Answer 31

They lose elasticity and plaque can build up on the walls

Question 32

Varicose veins

Answer 32

They are enlarged, dilated veins due to too much pressure

Question 33

Blood pressure

Answer 33

The pressure of the circulating blood against the walls of blood vessels

Question 34

What are blood vessels

Answer 34

Arteries, capillaries, venules and veins

Question 35

Osmotic pressure

Answer 35

Pressure that is due to proteins staying in capillaries

Question 36

What are capillaries the location for

Answer 36

The exchange between plasma, tissue fluid and cytosol

Question 37

Cytosol

Answer 37

Guild of the call

Question 38

How does oxygen and nutrients move

Answer 38

From blood to tissues

Question 39

How does waste at CO2 move

Answer 39

From tissues to blood

Question 40

Movement of things in capillaries Proteins Water, oxygen, glucose CO2, waste

Answer 40

Proteins stay in, water and oxygen and glucose move out, CO2 and wastes movie in

Question 41

How does blood get oxygenated

Answer 41

Passes through the lung tissue. Where oxygen bonds with hemoglobin

Question 42

Hemoglobin

Answer 42

The protein in red blood cells that pick up oxygen

Question 43

How is blood pressure after getting oxygenated

Answer 43

It is 1/3 less of the pressure for when it first come out of the heart

Question 44

How does fluid exchange effect blood volume

Answer 44

No change in total blood volume

Question 45

Histamines

Answer 45

Enlarged pours in blood vesicles

Question 46

What do metarterioles

Answer 46

They bypass capillaries, shut blood directly between arteriole and vein

Question 47

What is the Lymphatic system

Answer 47

It is thin walled vessels that drain excess fluid. It cleans fluids with the lymph nodes.

Question 48

What is the relationship between capillaries and lymph vessels

Answer 48

Excess water and solutes that are filtered out of the capillaries are then picked up my the lymph vessels and then go back into circulation

Question 49

How is the heartbeat controlled

Answer 49

Intrinsically and extrinsically

Question 50

What is an intrinsically controlled heartbeat

Answer 50

It means the best is regulated by mechanisms in the heart not the brain

Question 51

Extrinsic heartbeat

Answer 51

Slowed and sped up by brain impulses but not controlled

Question 52

Intrinsic heat control

Answer 52

Nerve tissues embedded in cardiac cells controls the heart

Question 53

AV node (atrioventricular)

Answer 53

The AV node conducts impulses and controls the fate at which they are sent to the ventricle (right side)

Question 54

SA node (sinoatrial)

Answer 54

The pacemaker starts impulses and trigger contraction of the atria

Question 55

How many steps of the heartbeat

Answer 55

5

Question 56

Step 1 of heartbeat

Answer 56

Electrical activity goes to the Av node through internodal pathways

Question 57

Step 2 heartbeat

Answer 57

Depolarization speeds across the right atria and is slowed by the AV node

Question 58

Step 3 of the heartbeat

Answer 58

Depolarization moves through the ventricular conducting system to the apex of the heart
