What happens when coronary artery becomes occluded?
There will be reduced blood flow to the myocardium and the duration and severity will determinate the fate of the compromised myocardium.
Some of the features are systolic and diastolic disfunction, elevation of filling pressures, electrocardiographic changes and pain.
In case of prolonged cessation of blood flow the myocardial infarction is the final outcome.
Where is the jugular vein located on the wrist?
The jugular vein is not located on the wrist; it is primarily found in the neck. There are two main jugular veins on each side of the neck: the internal and external jugular veins, which drain blood from the head and neck back to the heart. If you're looking for major veins in the wrist, you would be referring to the radial and ulnar veins.
What veins drain the areas supplied by the carotid artery?
The areas supplied by the carotid artery are primarily drained by the internal jugular vein and the external jugular vein. The internal jugular vein collects blood from the brain, face, and neck, while the external jugular vein drains the superficial structures of the head and neck. Additionally, smaller veins such as the facial vein and the thyroid veins also contribute to draining regions supplied by the carotid artery.
Incision of the vein is called "venotomy." This surgical procedure involves making an incision in a vein, typically for the purpose of accessing the venous system for blood sampling, catheter placement, or other medical interventions. Venotomy is often performed in clinical settings, such as during surgeries or for therapeutic treatments.
How does blood return to the heart in the femoral vein?
Blood returns to the heart through the femoral vein by a combination of factors. The contraction of leg muscles during movement helps propel blood upward against gravity, while one-way valves in the vein prevent backflow. Additionally, the pressure changes in the thoracic cavity during breathing further assist venous return. Ultimately, the femoral vein drains into the external iliac vein, which then joins the inferior vena cava to return blood to the heart.
