Physiological Factors influencing RBC number
• The RBC count is higher in children than in adults, and it is quite high during birth (8–10 million mm).
• During excitement, the RBC count rises at high elevations and in warm weather.
• During pregnancy, women’s red blood cell counts are often low. Low altitude is associated with a decrease in RBC count.

Blood: Definition, Functions, and Components

Leave a Comment / Animal Taxonomy, Zoology /

Blood is a fluid connective tissue. It moves continuously throughout the body, enabling continuous contact with tissues that are far apart. About 7% of a 72 kg man’s body weight is made up of blood (5.6 litres). Women have a lower proportion, but children have a higher proportion (which steadily declines until it reaches the adult level).

Banana: Introduction, Geographical distribution, Morphology, Phytochemical constituents, Pharmacological activities and Traditional Uses

1. The banana plant, Musa paradisiaca, is a big herb with a succulent, very juicy stem that is a cylinder of leaf-petiole sheaths. It is often mistakenly called a “tree” and can grow up to 20 to 25 feet (6 to 7.5 meters) tall, emerging from a thick rhizome or corm.
2. The leaves are smooth, soft, elliptic or oblong, and they are numbered 4 or 5 to 15. They are spirally arranged, and they unfold once a week as the plant grows.
3. The inflorescence, a terminal spike that emerges from the heart at the tip of the stem, is an altered growth point. Initially, it appears as a big, tapering, long-oval bud covered in purple. The slender, nectar-rich, serrated, white blooms are arranged in whorled double rows along the flowering stalk as it opens, with a thick, waxy bract that resembles a hood and is deep red inside.

Milk: Meaning, Physical and Physico-Chemical Properties, Constituents, Production, and Trade

Leave a Comment / General Questions /

Milk is the secreted fluid of the mammary glands of female mammals. It has almost all of the nutrients needed to keep life going. Goat, sheep, and cow milk have been utilized as food by humans since the beginning of time. The word “milk” is now used interchangeably with cow’s milk. When provided commercially, the milk of other animals is identified, such as goat or sheep milk. Mammals’ mammary glands generate the white liquid meal known as milk. For young mammals, including breastfed human newborns, it serves as their main source of nutrition until they can process solid food. In addition to lactose and saturated fat, milk also includes calcium and protein. Milk immunity is a result of immunological factors and immune-modulating substances in milk.

Queen’s-tears: Introduction, Classification, Habitat, and Morphology

Leave a Comment / Botany, Plants /

The Bromeliaceae family includes the vascular plant species known as Billbergia spp. The Queens Tears plant, or Billbergia nutans H. Wendl. Ex Regel, is one of the most widely marketed species. The species of the Bromeliaceae family, also known as bromeliads, are sold as attractive plants and are frequently utilized in landscaping and interior design projects. Some species are in danger of going extinct as a result of increased unlawful harvest in their native growing habitats in recent years because of the growing demand for these ornamental species (Cooper and Cave, 2019; Rejane et al., 2012).

Diabetes: Meaning, origin, Types, Risk factors, Symptoms, Complications of diabetes and diagnoses

Leave a Comment / Zoology /

Diabetes is a metabolic disease, characterized by hyperglycemia, or high blood sugar levels. Normal digestion of food produces glucose, which enters the bloodstream and serves as the body’s fuel. Insulin, a hormone produced by the pancreas, helps in transferring glucose from the bloodstream into the liver, muscles, and fat for use as fuel.

Althaea rosea is a member of the Malvaceae family. The Greek word altho, which means to cure, is the source of the generic name Althaea. Hollyhocks are tall, unbranched plants that can be annual, biennial, or perennial. Star-shaped hairs typically cover the herbage. The leaf blades are carried on long petioles and are frequently serrated or lobed.

Happiness tree: Introduction, Classification, Distribution, Chemical constituents, Morphological Characters and Uses

Garcinia subelliptica, widely referred to as the Fukugi tree or happy tree, is an evergreen that grows in coastal forests in East and Southeast Asia, particularly in the Ryukyu Islands of India, Japan, Taiwan, the Philippines, Indonesia, and Sri Lanka. Native to the tropics and subtropics of Asia and Africa, fukugi trees are members of the Clusiaceae family, specifically the species Garcinia. The genus includes beautiful plants with a thick green leaf canopy. When fully grown, fukugi trees—evergreen tropical trees—are 10 to 15 meters tall. Because they only have one primary trunk supporting alternating pairs of erect branches, fukugi trees are very unique. This results in compact, conical crowns. Because they are compact and erect, these trees are planted as windbreaks on Okinawa.
