Circulatory Disturbances Flashcards
Dynamics of blood flow
Hemodynamics
The manner of development of disease
Pathogenesis
The metabolism of organs and cells depends on an intact circulation for continuous delivery of
oxygen
nutrients
hormones
electrolytes
water
The metabolism of organs and cells depends on an intact circulation for the removal of
Metabolic waste and carbon dioxide
Delivery and elimination at the cellular level are controlled by exchanges between the
intravascular space
interstitial space
cellular space

“The well-being of tissues requires normal fluid balance. Abnormalities in ______________ can result in cellular injury even if the blood supply is intact.”
vascular permeability and hemostasis
Chambers by the heart are separated by
Interatrial septum
Interventricular septum
Capillary ends
Arterial ends
venous ens
Circulatory blood flow staring from the Aortae
Aortae → Major Arteries → Arterioles → Capillaries → Venules → Major Veins → VenaCavae → RA → RV → PulmonaryArteries → Lungs → PulmonaryVeins → LA → LV → Aortae
Chambers of the heart
Atria
Ventricles
The survival of cells and tissues is exquisitely dependent on the oxygen provided in a normal blood supply and therefore on
the delivery of sufficient blood through a patent circulatory system
The valve between the right atrium and right ventricle pushes blood from the RA to the RV during diastole and prevents regurgitation from the RV to the RA during systole.
Tricuspid Valve
Valves of the heart
Tricuspid valve
Mitral or Bicuspid valve
Pulmonary valve
Aortic valve
The amount of fluid that has been distributed should also be the substantial amount that would be brought back into circulation for its efficiency.
Starlings law

Quadruped
Two divisions of aorta
Abdominal and Thoracic Aorta
The velocity flow and the mean pressure is sustained by
Hydrostatic Pressure and Osmotic Pressure
The Continuous type of Capillary that is true for the
Brain (BBB)
Muscle
Lung
Bone
Three main types of Capillaries in microcirculation
Continuous Endothelium
Fenestrated Endothelium
Discontinuous Endothelium
It has fenestra or pores that allow filtration enabling some of the molecules to pass through
Fenestrated Endothelium
Fenestrated endothelium type of capillary is true for the
Renal glomeruli
Intestinal villi
Endocrine glands
Choroid Plexuses
Ciliary processes of the eye
Very open gap that allows the passage of large molecules
Discontinouos (sinusoidal) endothelium
Discontinouos (sinusoidal) endothelium type of capillary is true for the
Liver Sinusoids
Spleen Sinusoids
Bone Marrow
Lymph Nodes
In endocrinology, hormones are not secreted through the lumen of the epithelial gland. If this is true, then where are hormones being secreted?
Secretion happens via the Fenestrated endothelium type of capillary
