Surgical puncture of a joint to aspirate (suction) fluids from the synovial cavity is called Arthrocentesis
Red blood cells (erythrocytes)
The red blood cells are highly specialized, well adapted for their primary function of transporting oxygen from the lungs to all of the body tissues. Red cells are approximately 7.8 μm (1 μm = 0.000039 inch) in diameter and have the form of biconcave disks, a shape that provides a large surface-to-volume ratio. When fresh blood is examined with the microscope, red cells appear to be yellow-green disks with pale centres containing no visible internal structures. When blood is centrifuged to cause the cells to settle, the volume of packed red cells (hematocrit value) ranges between 42 and 54 percent of total volume in men and between 37 and 47 percent in women; values are somewhat lower in children. Normal red blood cells are fairly uniform in volume, so that the hematocrit value is determined largely by the number of red cells per unit of blood. The normal red cell count ranges between four million and six million per cubic millimetre.

I feel like the answer is laugh and seek fun activities
Answer:
Dental models are created whenever the dentist needs to study the size and relationship of the teeth, gums and dental arches. This is the case whenever the dentist is studying a patient's growth and development, or when significant dental treatment is being contemplated.
