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

March 16, 2023April 11, 2023 - 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.

Veins – Structure , functions ,Venous System and Circuits and Vein Valves

March 16, 2023April 11, 2023 - by Jaishree Gorane - 6 Comments.

Veins are vital blood vessels that collect oxygen-poor blood and transport it back to the heart. They are made up of three layers of tissue and fibers, and can contain one-way valves that keep blood flowing in the right direction. Veins transport oxygen-poor blood throughout the body and oxygen-rich blood from the lungs back to the heart. Veins require external forces such as breathing and muscle movement to push blood in the right direction.

Arteries in The Body

March 14, 2023April 11, 2023 - by Jaishree Gorane - 7 Comments.

Arteries in the body are an essential component of the Circulatory System. There are two main circuits- Pulmonary and Systemic Circuit. Arteries are classified based on their size and composition. Elastic arteries, such as the aorta, are the largest and most flexible, while muscular arteries and arterioles are responsible for directing blood flow to specific areas. Major arteries, including those in the head and neck, torso, abdomen, arms and legs play vital roles in delivering oxygen and nutrients throughout the body.

Why Do Arteries Have Thick Elastic Walls ?

March 10, 2023March 12, 2023 - by Jaishree Gorane - 5 Comments.

Arteries have thick elastic walls for several reasons like regulating blood pressure, resisting wear and tear, maintaining efficient blood flow, protecting against aneurysms and preserving structural integrity. The tunica media layer, which contains smooth muscle cells and elastic fibers, allows for contraction and relaxation to adjust the diameter of the blood vessels. The reasons for thick elastic walls in arteries are essential for the proper functioning of the circulatory system.

How Amoeba Acquires its Food through the Process of Phagocytosis

March 2, 2023May 30, 2023 - by Jaishree Gorane - 6 Comments.

Amoeba, a single-celled organism, acquires its food through the process of phagocytosis. During this process Amoeba uses pseudopodia to engulf its prey and forms a membrane-bound phagosome which fuses with lysosomes to form a phagolysosome. The prey is then digested. Factors such as temperature, pH and food availability affect the efficiency of phagocytosis in amoeba.

Difference between Lymph and Plasma

February 27, 2023February 9, 2024 - by Jaishree Gorane - 4 Comments.

Lymph and plasma are both important components of the body’s circulatory system but they differ in their composition, production and function. Lymph is a clear colorless fluid that is produced by lymphatic vessels and plays a vital role in immune system function. Plasma is a yellowish liquid that makes up the liquid portion of blood and is essential for the transport of nutrients and waste products throughout the body. Difference between lymph and plasma explained in easy words to understand and write in points for school assignments and exams

13 Important Differences between Lymph and Blood

February 24, 2023December 23, 2023 - by Jaishree Gorane - 7 Comments.

Blood and lymph have many differences in their composition, role, production, circulation, supply of nutrients, flow, color, functions, donation and transfusion, formation of clots, movements, and oxygen level. Blood carries oxygen and nutrients to tissues, while lymph removes waste and fights infection. Blood is produced in bone marrow, while lymph is produced in lymph nodes. Blood circulates through the heart and vessels, while lymph moves through lymphatic vessels. Blood is red, while lymph is colorless.Explained thoroughly to understand the concept and for school assignmenents and exams
