Arthritis Joints in our body are prone to erosion that could cause friction due to the depletion of supporting tissues between two bones of the joints. Prolonged friction can cause the wearing off of cartilage and ligaments, resulting in arthritis. Arthritis is a non-communicable joint disease that could affect any significant body joint. We can define Arthritis as inflammation in the joints, which can have symptoms like stiffness, intense pain, and swelling and redness around the joints. Symptoms and causes Arthritis can affect various joints in the body as well as organs. Common symptoms of arthritis can be severe pain, ... Read More

Arthritis: Definition Arthritis can cause inflammation in joints. Inflammation is a defensive action by body tissues towards damage that could be caused by physical agents or by microbial infection. Arthritis can be identified with intense pain, swelling, and redness around that joint. It could cause difficulty in using and moving that joint. Arthritis cannot be associated with any age group or gender, or pedigree. Arthritis is either a genetic disorder, although the wear and tear due to prolonged stiffness cause inflammation in joints, resulting in arthritis. Types and symptoms There are two main kinds of arthritis. They are − ... Read More

Introduction − Blood Pressure Blood pressure is the force that blood exerts against the artery walls when the heart beats. With distance from the left ventricle, the pressure decreases gradually. The blood pressure measurement can be checked based on two type of pressure measurements. The are − The first is Systolic Blood Pressure and The second is Diastolic Blood Pressure. Systolic Blood Pressure Systolic Blood Pressure measurement is the measurement of the pressure in the blood vessels that is created when the heart beats. Diastolic Blood Pressure Diastolic Blood Pressure measurement is the measurement of the force on ... Read More

The blood in the human body seems to be the same in color but is different in terms of its characteristics. The blood type has been divided into two main groupings, namely − ABO Grouping Rh Grouping. Let us see in detail about these two main blood groups. Images Coming soon ABO Grouping The presence and absence of two surface antigens, namely, A & B on the surface of red blood cells (RBC), determines the ABO grouping. Antigen− Antigen is a substance that activates the immune system to respond against that substance. Antigens can be bacteria, viruses, toxins, ... Read More

Ankle Joint The ankle joint is a complex system of a combination of bones, ligaments and muscles that hold together the foot in place. Built to serve several purposes like bearing weight, mobility, adaptability and stability, the ankle and the foot together serve as a connection to the ground. The ankle must withstand body weight as well as to adapt to the changing surfaces on which we walk. The ankle is made up of two joints − the true ankle joint and the subtalar joint. The true ankle joint is a specially designed joint that holds together the leg ... Read More

Three Main Bones of the Leg Starting from the hip to the ankle, three bones which form the leg are as − Femur Tibia Fibula. Femur − Femur is the single, thick bone that runs from the hip joint to the knee joint. It’s the strongest bone of the leg accounting for one-quarter of the total height of a person. Tibia − Tibia runs along the lower leg, and is called the shin bone. Along with the fibula, it runs from the knee joint to the ankle. It is stronger and thicker than fibula. Fibula − Fibula along ...

The Foot The foot is one of the intricate structures comprising 26 bones linked at 33 joints. The foot bones provide mechanical support both while walking and standing by supporting the body weight. The foot bones are grouped under the following three categories − Tarsals Metatarsals Phalanges. Tarsals A set of seven irregular bones form the tarsals situated at the proximal end of the ankle joint. Let us see each set in detail spreading out from the ankle joint. The talus or ankle bone − the two lower leg bones, tibia and fibula, connect with the talus ... Read More

Blood Circulatory System The human circulatory system, also known as the blood vascular system, is made up of a muscle-chambered heart, a network of closed branching blood arteries, and blood, which is the fluid that circulates.Alternatively, the circulatory system is in charge of collecting metabolic waste and toxins from cells and tissues so that they can be cleansed or evacuated from the body. Images Coming soon Organs of the Circulatory System Our heart is the only circulatory system organ. Heart The mesodermally derived organ, the heart, is located in the thoracic cavity, between the two lungs, and is slightly inclined ... Read More
