What is the Structure of Nephron and its Functions?

What is the Structure of Nephron and its Functions?

Do you know the structure of the kidneys in the human body? The kidney is one of the endocrine glands. It is making “kinins,” secreting “rennin,” and “erythropoietin,” forming “1,25-dihydroxycholecalciferol.” Kidneys are made up of many functional microscopic units called “nephrons.” They perform excretory and homeostatic functions, and there are 1.3 million nephrons in each…

What are Vacuoles? Why these are called Storage Bubbles?

What are Vacuoles? Why these are called Storage Bubbles?

A vacuole is a membrane-bound organelle found in the cells of eukaryotic organisms. It is a fluid-filled sac that is used for a variety of functions, including storage, waste disposal, and maintaining the cell’s shape. Vacuoles are found in both plant and animal cells, but they are more prominent in plant cells and can make…

Meiosis: The Process of Germ Cell division

Meiosis: The Process of Germ Cell division

Meiosis is a type of cell division that occurs in sexually reproducing organisms and is essential for the production of genetically diverse offspring. It involves the reduction of the chromosome number by half, which ensures that each daughter cell receives the correct number of chromosomes. During meiosis, the genetic material of each parent is divided…

What are the types of Muscles, Structure, and functions?

What are the types of Muscles, Structure, and functions?

The muscle is a contractile tissue. Muscle cells are specialized for contractile ability.  The characteristic property of muscular tissue is its ability to contract when excited. The property of conductivity is also well developed in muscular tissue through not to the degree as that of nervous tissue. This topic covers the types of muscle, skeletal…

What is mitosis? Steps of Mitosis and Importance

What is mitosis? Steps of Mitosis and Importance

Mitosis is the simplest type of cell division, which is responsible for the growth of tissues and individuals. the phenomenon of mitosis is of universal occurrence and is found in all living beings from the smallest bacterium to the largest animal. It shows a marked similarity in its minute’s details in all organisms. The term…

What is Thermodynamics? Explain the Thermodynamic Laws?

What is Thermodynamics? Explain the Thermodynamic Laws?

Energy exists in many forms, such as heat, light, chemical energy, and electrical energy. Energy is the ability to bring about change or to do work. Thermodynamics is the study of energy. The thermodynamics is concerned with energy changes accompanying a given process (physical or chemical) and not with the total energy of the body….

Lysosomes: Structure and Functions

Lysosomes: Structure and Functions

Lysosomes (Laso = dissolving; some = body) are membrane-bound spherical organelles containing lysosomal enzymes, that are hydrolytic in nature. Important enzymes present in the lysosome are acid hydrolases, proteases, lipases, and acid phosphatases. Let us see why lysosomes are called “suicidal bags of the cell.” Lysosomes are small, spherical organelles found in the cytoplasm of…

VITAMINS: What are Vitamins and its sources (Basic Guide)

VITAMINS: What are Vitamins and its sources (Basic Guide)

In developed countries, vitamin deficiencies result mainly from poverty, food fads, drugs, or alcoholism. Vitamin toxicity (hypervitaminosis) usually results from taking mega doses of Vit.A, D, B6, or niacin. It may be fat soluble (A, D, E, and K) and water-soluble (B and C). The B vitamins include biotin, folate, niacin, pantothenic acid, riboflavin, thiamine,…
