What is the role of the zona pellucida in the fertilization process?

What happens when the sperm plasma membrane fuses with the egg plasma membrane during fertilization?

What is the main function of the kidneys in maintaining homeostasis?

Hormone Functions

Aldosterone's primary function in the kidneys is to regulate electrolyte balance and blood pressure by stimulating the reabsorption of sodium and water in the distal tubules and collecting ducts.

Hormone Regulation

The hypothalamus releases corticotropin-releasing hormone (CRH), which stimulates the release of adrenocorticotropic hormone (ACTH) from the anterior pituitary gland, ultimately leading to the release of antidiuretic hormone (ADH) from the hypothalamus.

Fertilization Process

The zona pellucida is a glycoprotein layer surrounding the oocyte, playing a crucial role in the fertilization process by allowing only sperm with the correct receptors to bind and undergo fusion.

Fertilization Mechanism

During fertilization, the sperm plasma membrane fuses with the egg plasma membrane through a process called gamete membrane fusion, resulting in the formation of a zygote.

Kidney Function

The main function of the kidneys in maintaining homeostasis is to regulate electrolyte balance, blood pressure, and pH levels by controlling the excretion and reabsorption of ions, water, and waste products.
