Birth – All About I Have To Know
Birth is the act or process of bearing or bringing forth offspring, also referred to in technical contexts as parturition. In mammals, the process is initiated by hormones which cause the muscular walls of the uterus to contract, expelling the fetus at a developmental stage when it is ready to feed and breathe. In some species the offspring is precocial and can…

Fetal Development – Stages of Growth Step By Step
Fetal Development – Stages of Growth Step By Step/Within 24 hours after fertilization, the egg that will become your baby rapidly divides into many cells. By the eighth week of pregnancy, your baby will change names from an embryo to a fetus. There are about 40 weeks to a typical pregnancy. These weeks are divided…

Fifth Through Eighth Weeks of Stages Fetal Development
Fifth Through Eighth Weeks of Stages Fetal Development /Weeks five through eight of gestation are characterized by the development of the major organ systems, including the circulatory, nervous, lymphatic, and gastrointestinal systems. During this time, the embryo is extremely susceptible to the effects of teratogens. Development Cardiovascular System The first organ system to develop during…

Fourth Week of Development of Embryo
Fourth Week of Development of Embryo (the embryonic disc) will grow from about 2 to about 6 mm. The processes of the third week (neural tube formation, development of blood circulation) continue in the fourth week. At the same time, the amnion increases enormously in size, while the yolk sac does not. This is the…

What is the most common cause of acute kidney injury?
What is the most common cause of acute kidney injury?/Acute kidney injury (AKI), previously called acute renal failure (ARF) is a sudden decrease in kidney function that develops within 7 days, as shown by an increase in serum creatinine or a decrease in urine output, or both.[rx] Causes of AKI are classified as either prerenal (due to decreased blood flow to the kidney),…

Acute Kidney Injury – Causes, Symptoms, Treatment
Acute kidney injury (AKI), previously called acute renal failure (ARF) is a sudden decrease in kidney function that develops within 7 days, as shown by an increase in serum creatinine or a decrease in urine output, or both.[rx] Causes of AKI are classified as either prerenal (due to decreased blood flow to the kidney), intrinsic renal (due to damage to the kidney itself),…

Third Week of Development – Anatomy, Types, Functions
Third Week of Development/The third week is concerned with establishing left and right handedness, the craniocaudal axis, as well as the conversion of the bilaminar disc into a trilaminar embryo. Additionally, there is further specialization of the extraembryonic structures that will continue to support the embryo during the intrauterine phase. Gastrulation During gastrulation, the embryo…

Trophoblast Development – Anatomy, Mechanism
Trophoblast Development/Week 2 is often referred to as the week of twos. It’s the week when the embryoblast, extraembryonic mesoderm and trophoblast each separate into two distinct . Trophoblast Development Trophoblasts are the outer layer of cells that provide nutrients to the embryo and form part of the placenta. Key Points The trophoblast is subdivided into two layers, the inner cytotrophoblast,…

The First Week of Embryonic Development
The first week of embryonic development is filled with an eclectic arrangement of physical and biochemical changes. Each step is a part of a cascade of events that must be intricately coordinated in order to produce a healthy baby at the end of the thirty eight to forty week period. However, the events of the first…

Female Reproductive System
Oogenesis is the maturation of the female gametes through meiotic division. Key Points Oogenesis starts with the process of developing oogonia via the transformation of primordial follicles into primary oocytes, a process called oocytogenesis. Oocytogenesis is complete either before or shortly after birth in humans. During the menstrual cycle primary oocytes complete maturation through further…
