During inspiration, a diameter decrease of the inferior vena cava (IVC) of 50% or more has been seen as a marker of normal central venous pressure.
<h3>What is the vena cava? </h3>
Large veins that convey deoxygenated blood to your heart so it may receive oxygen are called the superior vena cava and inferior vena cava. The biggest vein in your body, the inferior vena cava, returns oxygen-depleted blood from the lower half of your body to your heart (below your diaphragm).
Your heart receives oxygen-poor blood from your upper body through your superior vena cava, your second-largest vein. The vital job of the superior and inferior vena cava is to transport oxygen-poor blood to the right atrium of the heart, where it passes into the right ventricle and then travels to the lungs (through the pulmonary artery) to exchange carbon dioxide for oxygen.
Blood that has been oxygenated returns to the left atrium of your heart via your pulmonary veins. Blood that is now carrying brand-new oxygen then travels to your left ventricle and aorta before being distributed throughout your body.
Therefore, a diameter decrease of the inferior vena cava (IVC) of 50% or more is a marker of normal central venous pressure.

Answer:
Trace the sperm from where they are produced to where they are ejaculated.
Explanation:
<u>The testicles</u> <em>are the site of the scrotum where semen is produced</em>. <u>The epididymis</u> <em>is a coiled structure that crowns the testicles and receives immature sperm from the testicles and stores them for several days. </em><u>When ejaculation occurs</u>,<em> semen is expelled from an</em> <u>extremity of the epididymis</u> <em>into the</em> <u>vas deferens</u>. <em>Subsequently, semen travels through the</em> <u>vas deferens</u> <u>to the spermatic cord</u> <em>in the pelvic cavity beyond the ureter and behind the bladder</em>. <em>There</em>, <em>the</em> <u>vas deferens</u> <em>join with the</em> <u>seminal vesicle</u> <em>to form the ejaculatory duct, which crosses</em> <u>the prostate</u> <em>and empties into</em> <u>the urethra</u>. When ejaculation occurs, <em>rhythmic muscle movements propel sperm forward.</em>

Explanation:
deficiency is a public health problem in more than half of all countries, especially those in Africa and South-East Asia. The most severe effects of this deficiency are seen in young children and pregnant women in low-income countries.
