What increases venous return?
According to Starling's law, an increase in venous return (i.e. increase in preload on the ventricles) results in a more effective contraction, hence augmenting cardiac output, as long as the actin and myosin fibrils in the muscle fibers are not overstretched. In the most simple terms, the more blood the heart collects blood from venous return, the more it is able to distribute through cardiac output. If venous return is poor, cardiac output will be poor- basically like a water pump that is connected to an insufficient supply of water.
What is the blood pressure within the right atrium called?
The blood pressure within the right atrium is called central venous pressure (CVP). It is a measure of the pressure in the large veins close to the heart and reflects the amount of blood returning to the heart.
What is the area in which cerebrospinal fluid collects before its return to the blood?
Cerebrospinal fluid collects in the venous sinuses within the brain before returning to the blood through the arachnoid granulations.
Whats venous fluid overload?
Venous fluid overload refers to an increase in the amount of blood volume within the venous system, which can lead to venous congestion. This can occur due to conditions like heart failure, kidney disease, or liver disease, causing symptoms like edema, shortness of breath, and fatigue. Treatment involves addressing the underlying condition and managing fluid intake.
Are there any veins in body which are valveless?
Batson's venous plexus, Thebesian (smallest cardiac) veins in the myocardium, and Emissarry veins draining from Dural Venous sinuses are all valveless.
What two things aide venous return within the body?

Changes occuring within or outside the body that affect nervous system functioning?
Stimuli
What do we call the fluid that is enclosed within the venous sinuses?
The fluid that is in the dural venous sinuses is venous blood that originates from the brain or cranial cavity. They collect blood from veins on the surface of the brain. Blood from the sinuses empties into the internal jugular veins

How wiretapping helps our country?
Wiretapping helps because it can help prevent terrorist attacks from occuring within the country.

Where does the venous sinuses of the brain lie?
The venous sinus o fthe scalp are those of the superior sagittal sinus. TO read more about it check the meninges. The dural venous sinus is below the cranium, fibrous and serous dura and the endothelium

Does the Inferior vena cava increase in size with valsalva maneuver?
Yes, during the Valsalva maneuver, the pressure within the chest increases, causing compression of the inferior vena cava. This compression may lead to dilation of the vessel to maintain venous return to the heart.
What is venous thrombosis prevention?
Venous thrombosis prevention involves measures such as staying active, avoiding prolonged periods of immobility, wearing compression stockings, and taking anticoagulant medications if necessary. It is important to manage risk factors such as obesity, smoking, and certain medical conditions to reduce the likelihood of developing venous thrombosis.
