What are the major vessels?

The Three Major Types of Blood Vessels: Arteries, Veins, and Capillaries. Blood vessels flow blood throughout the body. Arteries transport blood away from the heart. Veins return blood back toward the heart.

Which vein is blood most commonly taken from?

median cubital vein

What are the types of specimen collection?

The types of biological samples accepted in most clinical laboratories are: serum samples, virology swab samples, biopsy and necropsy tissue, cerebrospinal fluid, whole blood for PCR, and urine samples. These are collected in specific containers for successful processing in the laboratory.3

What are the 3 types of veins?

What are the different types of veins?

  • Deep veins are located within muscle tissue.
  • Superficial veins are closer to the skin’s surface.
  • Pulmonary veins transport blood that’s been filled with oxygen by the lungs to the heart.

What are the sites of blood collection?

Median cubital vein A superficial vein, most commonly used for venipuncture, it lies over the cubital fossa and serves as an anastomosis between the cephalic and basilic veins. 2. Cephalic vein Shown in both forearm and arm, it can be followed proximally where it empties into the axillary vein.

What is the most common method of venipuncture?

Vacuum Tube This is the basic, and most often performed, type of venipuncture procedure. It is also referred to as the Evacuated Phlebotomy Method. Using a system known as needle and sheath, the phlebotomist is able to fill several tubes from a single venipuncture.21

What are the 3 types of circulation?

3 Kinds of Circulation:

  • Systemic circulation.
  • Coronary circulation.
  • Pulmonary circulation.

What is the smallest vein?


What is the smallest vein in the body?

The smallest veins are called venules. They receive blood from capillaries and transport it to larger veins. Each venule receives blood from multiple capillaries.13

What are the 3 methods of venipuncture?

  • winged infusion set.
  • syringe needle method.
  • vacuum tub.

What is the purpose of performing venipuncture give 5?

There are five primary reasons for performing a venipuncture: Obtaining blood for diagnostic purposes. Monitoring levels of blood components. Administering therapeutic treatments (medications, nutrition, chemotherapy)

What are the layers of blood vessels?

Aside from capillaries, blood vessels are all made of three layers:

  • The adventitia or outer layer which provides structural support and shape to the vessel.
  • The tunica media or a middle layer composed of elastic and muscular tissue which regulates the internal diameter of the vessel.

What are the 5 Major blood vessels?

There are five classes of blood vessels: arteries and arterioles (the arterial system), veins and venules (the venous system), and capillaries (the smallest bloods vessels, linking arterioles and venules through networks within organs and tissues) (Fig 1).26

What is the most important vein in your body?

The superior vena cava is the large vein that brings blood from the head and arms to the heart, and the inferior vena cava brings blood from the abdomen and legs into the heart.30

What are the four phlebotomy techniques?

Results. Four different ways of taking blood were observed: cannulation and a syringe (38%), cannula with evacuated tube and adaptor (42%), syringe and needle into vein (14%) and evacuated tube system used conventionally (6%).23

What are the 4 major blood vessels?

The major blood vessels connected to your heart are the aorta, the superior vena cava, the inferior vena cava, the pulmonary artery (which takes oxygen-poor blood from the heart to the lungs where it is oxygenated), the pulmonary veins (which bring oxygen-rich blood from the lungs to the heart), and the coronary …4

What are the 2 largest veins?

The vena cava are the two largest veins that carry blood into the right upper chamber of the heart (the right atrium). The superior vena cava carries blood from the brain and arms into the top of the right atrium.

What are the two major blood vessels?

What are the three main types of blood vessels?

  • Arteries. They carry oxygen-rich blood away from the heart to all of the body’s tissues.
  • Capillaries. These small blood vessels connect the arteries and the veins.
  • Veins. These are blood vessels that take blood back to the heart.
