Q

what is the average heart beats per minute?

A

60-100 beats per minute

18
Q

can the heart contract with no neural input ?

A

yes it can

19
Q

what nerve controls the speed of heart contractions?

A

The Vagus Nerve

20
Q

what happens when the heart is in systole?

A

ventricular contraction, closing of AV valve, blood pumped out

21
Q

what happens when the heart is in distole?

A

heart is relaxed, blood pools into the ventricles from the atriums

22
Q

cardiac out put means what? and how is it calculated?

A

the total blood volume that gets pumped out of the ventricles per minute

CO = heart rate * stroke volume

23
Q

what are the three main vessels in the cardiovascular system

A

Veins, Arteries, Capillaries

24
Q

Veins Carry what kind of blood and where?

A

veins carry deoxygenated blood back to the the heart. except the umbilical and pulmonary veins

25
Q

Arteries carry what kind of blood and to where

A

arteries carry oxygenated blood from the heart to the rest of the body except for umbilical and pulmonary arteries

26
Q

Name two ways veins prevent back flow of blood when traveling

A

through valves forcing the blood upward

through the relationship with skeletal muscle contraction

27
Q

how many portal systems are there in the body?

A

three

28
Q

what are the names of the portal systems in the body?

A

hepatic portal system
hypophyseal portal system
renal portal system

29

A 
nutrients 
hormones 
gases 
blood proteins 
salts
31
Q

Erythroctes are what?

A

they are red blood cells

32
Q

How does erythrocytes carry oxygen?

A

they are bioconcave
and they have hemoglobin whose job is to carry oxygen
they also do not have nucleus and mitochondria to make more room for oxygen carrying

33
Q

leukocytes are what?

A

white blood cells

34
Q

where do thrombocytes come from and what are they

A

they are platelets and they come from bone marrow

35
Q

what is ABO

A

that is the system for identifying the antigens present on the cell surface of erythrocytes

36
Q

who can AB blood type donate blood to? and who can they receive blood from?

A

AB blood type can only donate to other AB blood types

they can receive blood from O A and B

37
Q

who can B blood type donate blood to? and who can they receive blood from?

A

they can donate to B blood type people

they can receive blood from O and B

38
Q

who can A blood type donate blood to? and who can they receive blood from?

A

they can donate blood to A blood type and they can receive blood from O and A

39
Q

Who can O blood type donate blood to? and who can they receive blood from?

A

O blood type can donate to A, B and AB

O blood type can only get blood from to O blood type

40
Q

what is erythroblastosis?

A

when the mothers antibodies start to attack the placenta with the fetus with a different blood type
