Tidal volume

A

Normal respiration

4

To remove irritants

13
Q

A
Chemoreceptors are changes in co2 and o2. 
Located in Brian (detects o2)
And body (peripheral detects co2) (coroided and aortic bodies)
14

A

A.B.AB.O.RH+
Donor: O-
Receiver: AB+

17

Blood clot on blood vessel. Forms on ruff area on vessel

18
Q

Process of clotting. What mineral is needed. what is a clot made of

A

Process: platelets-prothrombin-thrombin-fibrinogen-FIBRIN

Needs calcium

19
Q

what blood vessel carries deoxygenated blood from heart to lungs.

A

Pulmonary artery

20
Q

What is produced by red bone marrow?

A

RBC, WBC and platelets

21
Q

Lymphocytes

A

WBC that recognize foreign antigens and make antibodies

22
Q

What types of cell is the precursor to all type of blood cells

A

Stem cell

23
Q

What is lymph and where does if flow

A

Fluid that flows through the lymphatic system

24
Q

Lymph nodes and where are they located

A

Cluster of lymph tissue that preform phagocytosis, lymphocytes and macrgocytes
Located: cervical, inganal, thoracic and auxiliary

25
Q

How does the spleen process old RBCs

A

By forming billy Rubin

26
Q

What is hypoxemia and how do the kidneys compensate

A

Low o2 in blood. So kidneys secret erythropoietin to stimulate RBC

27
Q

What blood vessels supply the myocardium

A

Both coronary arteries

28
Q

What is the cardiac cycle

A

Atria contracts then ventricles

29
Q

Sac surrounding the heart and what prevents friction rub

A

Pericardium and pericardium fluid

30
Q

Path of blood flow

A

Lungs (right side)

Body (left side)

31
Q

What prevents back flow of blood from the pulmonary artery and aorta into the ventricles

A

Semilunar valves. ( both pulmonary and aortic)

32
Q

Normal heart sounds and what causes it

A

Lib dub ( s1 and s2)
S1 ( closure of AV)
S2 (closure of SV)

33
Q

ANH

A

Atrial natriuretic hormone
Atria releases ANH when heart is stretched - to stimulate kidneys - to eliminate water and sodium.
-decreases bp and strain on heart

34
Q

Electrical conduct through heart

A

SA node - AV node - bundle of his - perkunjie fibers

35
Q

Systole

A

Contraction of heart
