Arteries – Structure , Layers, Functions

March 12, 2023April 11, 2023 - 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.

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.

Difference between Double Circulation and Single Circulation

March 8, 2023June 27, 2023 - by Jaishree Gorane - 4 Comments.

The Difference between Double Circulation and Single Circulation lies in the number of circuits the blood passes through in its journey around the body. Single circulation occurs in fish, while double circulation occurs in mammals, birds and reptiles. The factors that differentiate the two include the presence of a pulmonary circuit, the number of chambers in the heart, the direction of blood flow etc.

Blood Vessels Diagram

March 7, 2023March 20, 2023 - by Jaishree Gorane - 3 Comments.

The blood vessels diagram shows the structure of arteries and veins. Arteries have a thick tunica media layer to handle the high-pressure blood flow while veins have a thinner tunica media and a larger lumen to accommodate a higher volume of blood. the smallest blood vessels have thin endothelial cell walls and a narrow lumen that allows for the exchange of nutrients and waste products with pericytes and red blood cells. A neatly labeled diagram makes it easy to understand.

How Lymph is Formed ?

March 1, 2023February 9, 2024 - by Jaishree Gorane - 5 Comments.

This article explains the formation of lymph, a colorless body fluid. It highlights that lymph originates as interstitial fluid, which collects in lymphatic capillaries, transforming into lymph. This fluid then passes through the lymphatic system, where it is filtered by lymph nodes before returning to the bloodstream. This process is essential for nutrient delivery, waste removal, and immune system support.

22 Differences Between Plasma and Serum

February 28, 2023December 23, 2023 - by Jaishree Gorane - 1 Comment

Plasma and serum are the two distinct components of blood that vary in definition, composition, and properties. Plasma comprises electrolytes, proteins, enzymes, hormones, metabolites, and clotting factors while serum is devoid of clotting factors. Both require different preparation methods, have clinical significance in disease diagnosis and treatment, and can be used for various purposes such as biomarker analysis, blood transfusions, and research studies. diffrence between plasma and serum explained for students to complete their assignments , homework and exams

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
