What stimulates the production of RBC? What is the name of this process?
Erythropoietin in response to hypoxia
Erythropoiesis

albumin-->globumin-->fibrinogen
globulin protein: metalloprotein
epicardium, myocardium, endocardium
After the right atrium, blood flows through where?

Pluripotent stem cells
what is the function of pneumocytes type II?
create surfactant

Neutrophils, Eosinophils, Basophils, Lymphocytes, Monocytes
what prevents the overstretching of heart valves? What opens and closes in response to pressure changes?
cardiac fibrous skeleton
heart valves
In the conducting system, what are the next two steps after impulse in generated for sinoatrial node?
Leukopoiesis
Hematopoietic Stem Cells (HSCs)
what are the three nerves that help regulate the "inspiratory center"
phrenic and intercostal nerves-- every respiratory cycle
Vagus CN X--expiratory and prevent overinflation
What is the function of thrombopoeitin?
stimulate the production of megakaryocytes and formation of platelets.
Give me the two types of cardiac cells and their function.
pacemaker cells: creates AP to generate heartbeat
contractile cells: produce contraction in response to AP
Give me the next 3 steps after blood enters mitral valve.
mitral valve-- left ventricle--- aortic valve--- aorta-- body
Kidney cells release EPO into the blood. What is the effector and what is the response?
EPO causes RED BONE MARROW to increase the rate of RBC production.
what is the function of alpha and beta cells? are they endocrine or exocrine?
alpha-- glucagon; sugar= low
beta-- insulin; sugar=high
Explain the three ways CO2 is carried in the body? 2 Points need to be included: how its carried by RBC and function of carbonic anhydrase
(1) CO2 in plasma (2) In RBC, some as carbaminohemoglobin (3) In RBC, most as bicarbonate. (carbonic anhydrase catalyzed CO2--> bicarb)
List the three aortic sinuses and what blood vessels they give rise to?
left aortic sinus---left coronary artery; right aortic sinus---right coronary artery; non-coronary sinus
Explain what is happening during the P Wave, QRS complex, and T wave
P wave: atrial contraction & depolarization--QRS complex: ventricular contraction & depolarization-- T wave: ventricular relaxation & repolarization
Explain how the Rh Hemolytic Disease of a newborn is created.
During first pregnancy, mom is Rh- and baby is Rh+. Due to mixing of blood via fetal circulation, mom creates antibodies to the baby. During the second pregnancy, these antibodies will attack the fetus' RBCs and result in hemolytic disease.
