When you get a small cut on your skin, blood oozes out from the cut. Clot is formed after some time. What causes blood to clot?
Platelets are responsible for blood clotting after a cut or injury. They collect quickly at the damaged area and release substances that help form a clot. The clot seals the wound, prevents excessive blood loss and protects the body from infection by blocking the entry of germs. This process is an iRead more
Platelets are responsible for blood clotting after a cut or injury. They collect quickly at the damaged area and release substances that help form a clot. The clot seals the wound, prevents excessive blood loss and protects the body from infection by blocking the entry of germs. This process is an important protective mechanism of connective tissue.

Humans can control voluntary movements with the help of skeletal muscles and the nervous system. Skeletal muscles are attached to bones and respond to signals sent by the brain through nerves. Activities such as running, writing, speaking and lifting objects are voluntary movements because they occur under conscious control and coordinated action of muscles and nerves.

The body performs many involuntary movements that occur automatically without conscious effort. Smooth muscles control movements in organs like the stomach and intestines during digestion, while cardiac muscles keep the heart beating continuously. These movements are regulated by the nervous systemRead more
The body performs many involuntary movements that occur automatically without conscious effort. Smooth muscles control movements in organs like the stomach and intestines during digestion, while cardiac muscles keep the heart beating continuously. These movements are regulated by the nervous system and are essential for maintaining life processes such as circulation, digestion and breathing throughout the body.

The nervous system controls sensing, communication and responses in the body. Specialised nerve cells called neurons receive signals from sense organs and transmit them to the brain or spinal cord. After processing the information, the nervous system sends instructions to muscles or glands. This cooRead more
The nervous system controls sensing, communication and responses in the body. Specialised nerve cells called neurons receive signals from sense organs and transmit them to the brain or spinal cord. After processing the information, the nervous system sends instructions to muscles or glands. This coordination helps the body react quickly and appropriately to environmental changes and internal needs.

Quickly pulling the hand away from something hot and remembering song lyrics are functions of nervous tissue. Neurons carry sensory messages rapidly to the brain and spinal cord, which coordinate immediate protective actions. Nervous tissue also processes, stores and recalls information, enabling meRead more
Quickly pulling the hand away from something hot and remembering song lyrics are functions of nervous tissue. Neurons carry sensory messages rapidly to the brain and spinal cord, which coordinate immediate protective actions. Nervous tissue also processes, stores and recalls information, enabling memory, learning and long-term coordination of thoughts, responses and body activities efficiently.
