|
CSF |
Increases WBC count |
|
|
Cardiac muscles |
Presence of cells that can initiate depolarization... Presence of Gap injections that allow ion flow between connected cells... Striations... Increased number of mitochondria than skeletal muscles |
|
|
Arterioles |
Transports blood to cells / tissues. |
|
|
Capillary |
Single layer of simple squamous epithelial tissue where exchange of materials like nutrients and gases occurs |
|
|
SA node |
Located in right atrium, and it starts heart contraction... self stimulating, controls for rhythm of contraction contraction |
|
|
AV node |
Located in atrial septum, controls ventricular contraction rate |
|
|
Factors affecting blood flow |
Diameter of blood vessel, blood viscosity, blood vessel length |
|
|
Blood pressure |
Force exerted by Blood on the walls of blood vessels... Generated by ventricular contraction... regulated by medulla oblongata |
|
|
CO |
SV×HR stroke volume and heart rate |
|
|
Vasoconstriction |
Slowest flow to tissues which increases resistance so it increases blood pressure |
|
|
Vaso dilation |
Increases flow to tissue which decreases blood pressure |
|
|
Blood viscosity |
Increases RBC number, decreased flow, increase resistance increase blood pressure |
|
|
Blood formation |
1. Stimulus: hypoxia,anemia 2. Production site of hormone: kidney enzyme in liver 3. Hormone: EPO release 4. Target site: red bone marrow 5. Action: increases erythrocyte production Response: increase oxygen levels |
|
|
Ekg cycle |
1. Before P wave-heart is relaxed (diastole) 2. P wave- atrial depolarization 3. PQ interval- Atria contract ( systole) 4. QRS complex- ventricular depolarization 5. ST interval- ventricles contract (systole) 6. T wave- ventricular repolarization |
|
|
Innate immunity |
Generic response to different pathogens... 1. Physical barriers- skin sweat, oil, mucous membrane, saliva 2. Chemical barriers - phagocytosis, inflammation, antimicrobial proteins, 3. Fever |
|
|
Adaptive immunity |
Ability to respond against specific foreign molecules or parts of molecules - T and B cells |
