Human Reproduction: Organs, Processes, and Stages
Human Reproduction
Human reproduction is sexual, so it needs the formation of gametes. The male gamete is the spermatozoon, and the female gamete is the ovum. The gametes are formed in specialized organs, which are called the testicles and the ovaries. The union of these cells is required for reproduction, which is fertilization, that gives rise to the forming of an egg cell or zygote, which forms the embryo in the uterus. This begins the period of pregnancy, which ends in the birth of the new being.

The Internal Environment and Blood
Cells live in an environment that provides the nutrients they need. In the same environment, cells release waste substances resulting from their metabolism. Multicellular organisms have an internal environment formed by interstitial plasma: a liquid that fills the existing spaces between cells. This needs to be renewed continuously. Blood renews interstitial plasma given that it circulates around the whole organism, carrying nutrients and removing waste products.

Human Body: Anatomy, Physiology, and Homeostasis
Our body is an organism; therefore, our body is made of organs. These organs have a lot of tissues, tissues are made of billions of cells, cells are made of molecules, and molecules are made of atoms.
Body Components
- Atom: It is the smallest unit of a chemical element, which maintains its properties and cannot be broken by any chemical means. It consists of protons and neutrons with electrons orbiting this nucleus.
- Molecule: It is a set of atoms; it is the smallest particle that presents all the physical
Epithelial Tissue: Types, Characteristics, and Functions
Epithelial Tissue
Epithelial tissue has two main forms: lining epithelia, which covers parts of the body (including the face’s interior), and glands originating from epithelial cells.
This tissue is formed by juxtaposed cells, closely attached to each other.
Lining Epithelia
Cells in this tissue are always based on the basement membrane. Just below it is the connective tissue, which nourishes the epithelial cells because they are mostly avascular (lacking blood vessels). Nutrient exchange occurs through
