Vena cava filters are usually inserted in to prevent PE caused by a thrombosis in a deep vein (DVT).

The inferior vena cava (or IVC) is the large vein that carries de-oxygenated blood from the lower half of the body into the right atrium of the heart. Other veins entering the atrium are the superior vena cava and the coronary sinus (vein from the heart muscle).

The vena cava (both) are very large veins. All veins carry blood back to the heart. In the case of the vena cava, this is blood from the upper body (superior vena cava) and from the lower body (inferior vena cava).

In some cases, you have absolutely nothing to worry about, but if you do get bit by a venomous spider than I'd recommend you get medical attention immediately, hesitation could cost you your life...espeacially if you get by a black widow or the violin spider.

Because the purpose of heart is to pump blood. But starfish don't have blood, instead they have a water vascular system.

The valves help to prevent blood from seeping backwards. They provide a one way valve. When valves begin to fail blood may become stagnant and cause unsightly varicose veins - usually in the legs..

Tixel Laser is a cutting-edge dermatological treatment that has gained popularity for its efficacy in addressing various skin concerns. When considering Tixel Laser, it's essential to understand both the benefits it offers and the associated costs.

Tixel Laser Treatment Cost:

The cost of Tixel Laser treatment can vary widely depending on several factors:

Treatment Area: The size and location of the treatment area greatly influence the cost. Smaller areas like the face may be less expensive than larger areas such as the chest or back.

Number of Sessions: Many individuals require multiple sessions to achieve their desired results. The number of sessions needed can vary depending on the specific skin concern being addressed.

Geographical Location: The cost of Tixel Laser treatment can also be influenced by your location. Treatments in urban areas with a higher cost of living may be more expensive than in rural areas.

Clinic Reputation: Reputable and experienced clinics or dermatologists may charge more for Tixel Laser treatments due to their expertise and the quality of service they provide.

Complexity of the Condition: Treating more complex skin issues may require more extensive Tixel Laser treatments, which can add to the overall cost.

As of my last update in September 2021, the average cost of a single Tixel Laser session ranged from $200 to $800 or more. However, prices can change over time, so it's essential to consult with a qualified dermatologist or clinic for the most up-to-date pricing information in your area.

No.

(Not counting the pulmonary veins)

the least "deoxygenated" blood is in the renal veins and the jugular.

(Neither the brain nor the kidneys use up all the oxygen in their blood supply.)

Blood flow to the skin is sometimes controlled by temperature - heat to be lost - and MAY be less desaturated.

The right atrium

The vena cava is the biggest artery in the body that is attached to the heart, so i would say the cardiovascular system.

the inferior vena cava caries de-oxygenated blood.

• If you gather all the veins and arteries together in your body, then it could wrap around the earth, twice!
• There are some veins and arteries that are smaller than a price of your hair!

There are 4 connecting arteries and veins in a frog

In the large veins.

Because in the large veins the blood must fight the gravity, the blood is flowing up, there are valves in them to prevent the blood to fall down again.

veins are blue in colour because they carry deoxygenated blood , which carries carbon dioxide with the help of carbamino acid

hemorrhoids

The capillarys are in the lungs and blood flows trough them.As far as I know, blood does not flow back through the capillarys so it most likely does not flow back through the capillary beds.

its may be due to right heart failure,which causes edema of the extermities and it may be due to emboli in your right arm vein which got swollen and causing pain,it may be due to hypertension which cause vericose vein,you should have ECG for heart and APPT and D-DIMER test for emboli.so go to hospital and see doctor
