Ventricular Septal Defect: Oxygenation Challenge in Infants
A Ventricular Septal Defect (VSD) is a congenital heart defect where a hole exists between the right and left ventricles of the heart. This condition presents a significant challenge for infants as it affects the proper oxygenation of their tissues. This explanation will delve into the details of how a VSD leads to an oxygenation…
The Respiratory Puzzle: Gaseous Exchange vs. Breathing
Respiration is a fundamental process for all living organisms, ensuring the supply of oxygen and the removal of carbon dioxide, critical for sustaining life. While “breathing” is a term we commonly associate with the respiratory process, it is essential to recognize that respiration is a multifaceted concept, involving both mechanical actions and intricate physiological processes.…
The Liver’s Role in Regulating Blood Glucose Levels
The liver plays a central and multifaceted role in the regulation of glucose in the human body. Glucose, a simple sugar, serves as the primary source of energy for cells, and maintaining its levels within a narrow range is crucial for overall health. The liver accomplishes this through various mechanisms, which we’ll explore in detail…

Blood vessels and their functions
Arteries are blood vessels which carry blood away from the heart. They have thick, muscular and elastic walls that can withstand the surge of the high-pressure blood pumped out of the heart.
EXCRETORY SYSTEM IN HUMAN
Except for urinary bladder which is endodermal in origin, the whole excretory system is Except urinary bladder which is endodermal in origin, the whole excretory system is Except mesodermal. In human the kidney is retroperitoneal i.e., the kidney is located outside the coelomic cavity and is covered by peritoneum (coelomic epithelium) from the ventral side…
Urine Formation
3−steps are involved in the formation of urine A) Ultra filtration It is filtration under pressure. Glomerular capillary pressure (45 mm of Hg) favours filtration. The Colloidal osmotic pressure (due to plasma proteins, particularly albumin) acts against filteration. Its value is ~20 mm of Hg. The Capsular filtrate pressure, due to the glomerular filtrate in…
An overview of Pituitary Gland
It is called master gland (master of endocrine orchestra) as it regulates the functioning of other endocrine glands like thyroid, Adrenal cortex, testes and ovaries etc. However, the secretions of pancreas, thymus and pineal body are not regulated by the hormones of the pituitary. Pituitary is a single or unpaired gland weighing about 0.5 gm.…
