Phloem – Definition, Structure, Function, Types and How does Phloem tissue work

- by Jaishree Gorane - 5 Comments.

Phloem tissue is a type of vascular tissue in plants that transports sugars, amino acids, hormones and other organic compounds from the leaves to the rest of the plant. The tissue is made up of several different types of cells like sieve tube elements, companion cells, phloem parenchyma and phloem fibers. Phloem tissue plays a critical role in plant growth and development by facilitating the transport of hormones, defending against pathogens, transmitting signals and storing nutrients. There are two types of phloem tissue- primary phloem and secondary phloem.

Xylem – Definition , Structure, Components (Types), Functions And Importance

- by Jaishree Gorane - 11 Comments.

Xylem is a specialized tissue in vascular plants that transports water and minerals from roots to the rest of the plant. It is composed of tracheids, vessel elements, xylem parenchyma, xylem fibers and xylem rays. Water transport is driven by root pressure and transpiration pull. Xylem provides structural support, stores nutrients and transports signaling molecules. Its transport mechanism is a combination of physical and biological factors.

Heart Valves- Types, Location, Structure and Functions

- by Jaishree Gorane - 3 Comments.

The human Heart has four chambers, and four valves ensure that blood flows in the correct direction. The valves are made up of thin flaps of tissue that open and close like doors. There are four main types of Heart valves – the Aortic Valve, Mitral Valve, Pulmonary Valve and Tricuspid Valve. Each valve plays a vital role in regulating blood flow in and out of the Heart. Any problems with the valves can lead to a variety of conditions that affect Heart function.

Capillaries – Definition, Location, Structure, Types, Functions and Importance

- by Jaishree Gorane - 1 Comment

Capillaries are tiny blood vessels connecting arterioles and venules, with a crucial role in exchanging glasses, nutrients and waste products. They are composed of a single layer of endothelial cells . They are classified into three types based on structure -continuous, fenestrated and sinusoidal. . Capillaries have various functions including oxygen and nutrient exchange, waste removal, regulation of blood pressure, heat exchange, immune response, hormonal regulation and disease diagnosis and treatment.

Types of Veins and their Functions

- by Jaishree Gorane - Leave a Comment

Veins are essential for the circulatory system, transporting blood back to the heart. Four main types of veins include pulmonary, systemic, superficial and deep veins, each with unique characteristics. Pulmonary veins carry oxygenated blood from the lungs to the heart’s left atrium, while systemic veins transport deoxygenated blood from the body’s tissues back to the heart. Superficial veins are smaller and near the skin’s surface and deep veins are larger and deeper in the body.

Arteries – Structure , Layers,  Functions

- by Jaishree Gorane - 7 Comments.

Arteries are essential blood vessels responsible for carrying oxygen-rich blood away from the heart and distributing it throughout the body. Arteries are thick, muscular, and elastic, designed to withstand high pressure. Arteries have three main layers – the Tunica Intima, Tunica Media and Tunica Adventitia – each with distinct structures and functions.
