In humans ,the brain use 15-20% of the body oxygen supply.

your brain may use up to 50 percent of the blood and oxygen.

Hello aspirant,

A typical skeleton structure of an infant has 300 bones.  These bones undergo a slow and consistent process called Ossification, in which the bones fuse together while the baby grows up. When the baby grows up into a healthy adult, there will only be 206 bones in his/her body.

Hope it helps. All the best.

All entering medical students must take Surgery Anatomy in which they dissect a human cadaver .  Almost every medical student wonders how he or she will react when it's time to start dissecting a dead body,

Human anatomy is the study of the structures of the human body. An understanding of anatomy is key to the practice of medicine and other areas of health.

Hope you understand , in case of any issue you can revert here.

thank you and all the best.

There are not just five senses in a human body. A healthy human can sense its environment and its internal state through dozens of channels. Eyesight provides the most information to the brain per second and is the most important sense. The second most information-rich sense is hearing. Next up comes the sense of touch. But what is commonly called the sense of touch is actually a group of many independent senses including: hot, cold, pressure, pain, itching, and tingling. Each of these senses has its own receptor and therefore its own unique path to the brain, as explained in the textbook "Psychology: Concepts and Applications" by Jeffrey S. Nevid. Furthermore, there are actually three different types of pain senses: skin pain, joint pain, and organ pain. The sense of smell and taste are the other two common senses most people think of. The senses perhaps most valued by athletes are the senses of linear and angular accelerations, which are carried out by the inner ear. These senses are commonly known as "balance". The kinesthetic sense is the body's ability to sense where its limbs are even with the lights off. Other senses with unique nerve pathways include stretching, suffocation, nausea, hunger, thirst, blushing, choking, and the need to urinate and defecate. Each of these dozens of senses plays a role in keeping us alive, well maintained, and interacting with our environment.

For the most part, the human body does not contain minerals. Scientifically speaking, a mineral is a naturally-occurring inorganic crystalline solid with a single chemical formula. Rocks are aggregates of minerals and organic materials. Except for in bones and teeth, the atoms and molecules making up a healthy body are not crystalline and are not solid. In this way, most of the molecules making up a human body fail to meet the definition of a mineral.

Hello student ,

Yes , there is only one part in the whole human body that gets oxygen directly from the air and not from the blood . The cornea is the only part of a human body that has no blood supply; it gets oxygen directly through the air. The cornea is the fastest healing tissue in the human body, thus, most corneal abrasions will heal within 24-36 hours

heart consists of four chambers, each separated by valves that only permit blood to flow in one direction.

The right side of your heart collects blood on its return from the rest of our body. The blood entering the right side of your heart is low in oxygen. Your heart pumps the blood from the right side of your heart to your lungs so it can receive more oxygen. Once it has received oxygen, the blood returns directly to the left side of your heart, which then pumps it out again to all parts of your body through an artery called the aorta.

Hey,

The human body is made up of billions of smaller components that are divided into four categories: cells, tissues, organs, and systems. An organ is a collection of various tissues that are structured in such a way that they may perform a certain function when combined.

The human body is a complex, well-organized organisation made up of individual cells that collaborate to perform the precise duties required for survival.

Hello aspirant,

Our body consists of a number of biological system that carries out specific functions necessary for every day living. The job of circulatory system is to move nutrients ,oxygen, blood , carbo dioxide hormones to the body. It consists of heart, blood , blood vessels, arteries and veins.

Respiratory is a biological system that consisting of various organs and structures used for gas exchange in animals and plants. Respiratory function is network of organs and tissues that helps you to breathe. Includes your lungs and blood vessels.The muscles that power your lungs are also part of the respiratory system.these parts work together to move oxygen throughout body and clean out waste like carbon dioxide.

Thankyou
