what is the objective of meiosis

result in reduction in chromosome numbers to half result of meiosis is 4 daughter cells

what is the importance of the haploid number

instead of having two sets of chromosomes you have one set

drain the anterior surface of the right ventricle and empty directly into the right atrium.

posterior veins

what system of veins drains the posterior abdominal and thoracic walls?

wet spirometer

Two containers (one open at the bottom, the other filled with water) and a tube that measure respiratory volumes and capacities (tidal volume, vital capacity, total lung capacity)

total volume

What is the term for the total volume of air moved in and out of the respiratory system per minute?
