11. Why spermatozoa normally arrive at the site of fertilization before the ova? narks)

## Step 1<br />The process of fertilization in humans involves the spermatozoa (sperm) and the ova (egg). The sperm are produced in the male testes and are released into the male reproductive tract during ejaculation. <br /><br />## Step 2<br />The sperm then travel through the male and female reproductive tracts to reach the site of fertilization, which is the fallopian tube. This journey is facilitated by the male reproductive system, which includes structures such as the vas deferens and the urethra.<br /><br />## Step 3<br />The sperm are designed to move quickly and are equipped with a tail that propels them forward. They also have a head that contains the genetic material necessary for fertilization.<br /><br />## Step 4<br />The ova, on the other hand, are produced in the female ovaries and are released into the female reproductive tract during ovulation. The ova are also equipped with a tail that helps them move towards the site of fertilization.<br /><br />## Step 5<br />However, the sperm are designed to move faster and are equipped with a tail that propels them forward. They also have a head that contains the genetic material necessary for fertilization.<br /><br />## Step 6<br />The sperm are also equipped with enzymes that help them penetrate the egg's protective layers. This allows them to reach the egg and fertilize it.<br /><br />## Step 7<br />The sperm's ability to move quickly and penetrate the egg's protective layers is crucial for successful fertilization. This is why sperm are produced in large quantities and are released into the male reproductive tract during ejaculation.
