Arteries of The Body

Arteries in The Body

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.

Arteries Have Thick Elastic Walls

Why Do Arteries Have Thick Elastic Walls ?

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

How Amoeba Acquires its Food through the Process of Phagocytosis

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.

How Lymph is Formed ?

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.

Difference between Lymph and Plasma

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

7 important Differences between Blood and Lymph

13 Important Differences between Lymph and Blood

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

Cardiac Cycle – Class 11th 

The cardiac cycle is the series of events that occur during one heartbeat where the heart contracts and relaxes to pump blood. It includes diastole and systole in which the heart’s chambers fill with blood and then contract to eject blood. The cardiac cycle is regulated by electrical signals, nervous system input, hormones, and it is important for diagnosing and treating heart conditions.
