The acrosome contains enzymes that break down the outer membrane of the egg cell, letting the sperm fertilize the egg.
What is an acrosome?
An acrosome is a unique membranous organelle that is located over the anterior part of the sperm nucleus. It is highly conserved throughout evolution.
This acrosome contains a number of hydrolytic enzymes that help the sperm penetrate the egg's coats, when secreted.
The proteolytic enzymes such as hyaluronidase and acrosin are what help the sperm penetrate the eggs coat.
Acrosome comes from the Golgi complex of the spermatid. It consists of a protein matrix core and numerous hydrolytic and glycolytic enzymes, which are necessary for fertilization.
Therefore, the acrosome contains enzymes that break down the outer membrane of the egg cell, letting the sperm fertilize the egg.

Hypervitaminosis D.
An uncommon but possibly dangerous disorder is hypervitaminosis D. When you consume too much vitamin D, it happens. Taking vitamin D pills in large doses frequently causes it.
Calcium levels in the blood can become excessively high when vitamin D levels are too high. Bones, tissues, and other organs may be impacted by this. If left untreated, it can result in excessive blood pressure, bone loss, and renal disease.
It frequently results from taking more vitamin D than is suggested each day. Check the amount of vitamin D in any multivitamins you take. If you are getting enough vitamin D from your multivitamin, you may not need to take additional calcium and vitamin D supplements.

In the cardiovascular system, the blood flows from <u>high pressure to low pressure.</u>
In the ventricular ejection phase, when the muscles of the ventricles contract, the<u> pressure gradient in ventricles rises</u>. This increases in the <u>pressure in the ventricles exceeds the pressure in the pulmonary artery </u>and aorta, thus opening pulmonary and aortic valves and ejecting the blood from the heart.
