Pregnancy is the most obvious answer. Ovulation is when cells are released from the ovaries.
Sperm cells are produced within tightly coiled tubes in the testicle called seminiferous tubules.
The collection of fertilized cells that is implanted in the uterus is called a blastocyst.
Make sex cells are called sperm and female sex cells are called ova
The flow of blood and tissue cells from the uterus is called menstruation. During menstruation, the lining of the uterus sheds and is expelled through the vagina. This process is accompanied by the flow of blood, which is a mix of tissue cells, uterine lining, and blood from the ruptured blood vessels in the uterus.
The gametes of a male animal are produced in the testes, and the gametes of a female animal are produced in the ovaries.They are developed in these gonads from specialized cells called germ cells.
Cells produced in the testes are called sperm cells. These cells are generated through the process of spermatogenesis, which involves multiple stages of cell division and differentiation within the seminiferous tubules of the testes.
Sperm is produced by the testes.Sperm is produced in the testes.
When the embryo reaches the uterus, it is a hollow ball of about 100 cells called a blastocyst. The blastocyst is made up of an outer layer of cells that will develop into the placenta and an inner cell mass that will develop into the embryo.
Cells within the kidney called interstitial fibroblasts produce a substance called erythropoietin, EPO for short, that stimulates production of red blood cells. They doesn't secrete or produce red blood cells themselves. Red blood cells are produced within bone marrow.
Insulin is not produced by pancreatic islet cells. It is produced by beta cells within the pancreatic islets of Langerhans, while glucagon is produced by alpha cells and somatostatin is produced by delta cells in the pancreatic islets.
Sex cells (sperm and eggs) are produced in the testes of males and the ovaries of females. In males, spermatogenesis occurs within the seminiferous tubules of the testes, while in females, oogenesis occurs within the follicles of the ovaries.
ADH (antidiuretic hormone), also known as vasopressin, is produced by cells within the hypothalamus and released by the pituitary gland in response to changes in blood osmolality.
