Quiz 2 Flashcards
5 functions of blood
- Transportation of gases, nutrients, hormones
- Regulation of pH
- Restriction of fluid loss at injury
- Defense against toxins and pathogens
- Stabilizing body temp
Erythropoietin
Stimulates red blood cell production due to anemia or blood loss
Agglutination
Clumping of cells to specific surface antigens and opposing antibodies
Surface antigens + opposing antibodies
Leukopenia
Lack of white blood cells
Leukocytosis
Excess of white blood cells
3 phases of homeostasis
Vascular phase
Platelet phase
Coagulation phase
Vascular phase
Cutting vessel wall
Platelet phase
Platelets attaching and plung vein
Coagulation phase
Blood begins to clot/ coagulate
Prothrombinase
Converts prothrombin to thrombin
Thrombin
Converts fibrinogen to fibrin threads
Central nervous system
Brain spinal cord
Peripheral nervous system
Sensory and motor
Acetylcholine
Neurotransmitter convert electrical signals to chemical signals at the synapse
Oculomotor
3rd cranial nerve
Constriction of pupil
Vagus nerve
10th cranial nerve
Cardiac, respiratory, blood pressure
Medulla
Cardiac center, vasomotor center, respiratory center
Pons

Parasympathetic
Relaxes, promotes normal function
Endocrine
Directly into blood stream
Hormones
Exocrine
Released through ducts
Tears
Sweat
Hormones
Chemical messengers
Lipids
Straight through
Proteins
Need second messenger
Epinephrin
Vasoconstriction
Heart beat more forcefully
Bronchial dilation
Anemia
Low oxygen carry capacity
3 phases of homeostasis
Vascular
Platelet
Coagulation
Cellular metabolism
Glucose+O2 = H2O + CO2 + ATP + heat
Heart valves
Tricuspid valve
Pulmonary valve
Mitral valve
Aortic valve
