Bone tissue is a type of connective tissue consisting mainly of a collagen matrix that is mineralized with calcium and phosphorus crystals..
What is an organ answer?
Organ, in biology, a group of tissues in a living organism that have been adapted to perform a specific function. … In higher animals, organs are grouped into organ systems; e.g., the esophagus, stomach, and liver are organs of the digestive system.
Is hair an organ?
Hair is an accessory organ of the skin made of columns of tightly packed dead keratinocytes found in most regions of the body. … The hair shaft consists of the part of the hair that is found outside of the skin. The hair shaft and root are made of 3 distinct layers of cells: the cuticle, cortex, and medulla.
Can you swallow your tongue?
Swallowing the tongue is virtually impossible. In the human mouth, a small piece of tissue called the frenulum linguae, which sits behind the teeth and under the tongue, keeps the tongue in place, even during a seizure.
Is skin an organ?
The skin is the largest organ of the body. The skin and its derivatives (hair, nails, sweat and oil glands) make up the integumentary system. One of the main functions of the skin is protection. It protects the body from external factors such as bacteria, chemicals, and temperature.
Is blood an organ?
Blood is both a tissue and a fluid. It is a tissue because it is a collection of similar specialized cells that serve particular functions. These cells are suspended in a liquid matrix (plasma), which makes the blood a fluid.
What are the 11 systems in the human body?
Functionally related organs often cooperate to form whole organ systems. There are 11 major organ systems in the human organism. They are the integumentary, skeletal, muscular, nervous, endocrine, cardiovascular, lymphatic, respiratory, digestive, urinary, and reproductive systems.
How many organs do humans have?
Altogether there are seventy-eight main organs within the human body. These organs work in coordination to give rise to several organ systems. Among these 78 organs, five organs are considered as vital for survival. These include the heart, brain, kidneys, liver and lungs.
Is the knee an organ?
Summary: Researchers suggest that viewing the knee as an organ in the same way doctors examine the heart for heart disease could lead to better therapies for treating osteoarthritis, one of the five leading causes of disability in elderly men and women.
What is the largest organ in the body?
Skin is the human body’s largest organ. Body organs aren’t all internal like the brain or the heart. There’s one we wear on the outside. Skin is our largest organ—adults carry some 8 pounds (3.6 kilograms) and 22 square feet (2 square meters) of it.
Can you live without a tongue?
Of course you can; the tongue is not a vital organ required for the successful function of the body. Many persons have had their tongues cut out as punishment for various infractions (e.g. in Byzantium), but lived. As many have noted, eating and speaking become much more difficult without a tongue, but it can be done.
Does tongue have bones?
The tongue is unique in that it is the only muscle that isn’t connected to bone at both ends. It is connected on one end to the hyoid bone, which is also unique as it is the only bone not connected to any other bone in the body.
What is an organ?
In biology, an organ (from the Latin “organum” meaning an instrument or tool) is a collection of tissues that structurally form a functional unit specialized to perform a particular function. Your heart, kidneys, and lungs are examples of organs.
What is an organ of the body?
Organs are the body’s recognizable structures (for example, the heart, lungs, liver, eyes, and stomach) that perform specific functions. An organ is made of several types of tissue and therefore several types of cells.
What is an organ made of?
An organ is made of several types of tissue and therefore several types of cells. For example, the heart contains muscle tissue that contracts to pump blood, fibrous tissue that makes up the heart valves, and special cells that maintain the rate and rhythm of heartbeats.
Is the tongue an organ?
The tongue is a muscular organ in the mouth. The tongue is covered with moist, pink tissue called mucosa. Tiny bumps called papillae give the tongue its rough texture. Thousands of taste buds cover the surfaces of the papillae.
What is human blood made of?
Your blood is made up of liquid and solids. The liquid part, called plasma, is made of water, salts, and protein. Over half of your blood is plasma. The solid part of your blood contains red blood cells, white blood cells, and platelets.
Is brain an organ?
The brain is arguably the most important organ in the human body. It controls and coordinates actions and reactions, allows us to think and feel, and enables us to have memories and feelings—all the things that make us human.
Is a heart an organ?
Your heart is actually a muscular organ. An organ is a group of tissues that work together to perform a specific function. In the case of your heart, this function is pumping blood throughout your body. Additionally, the heart is largely made up of a type of muscle tissue called cardiac muscle.
Is red blood cell a organ?
Areas covered: Here we provocatively comment on the potential classification of red blood cells – by far the most abundant host cell in the human body (~ 83% of the total cells) – as an organ involved in many functions beyond gas transport.
How blood is formed in our body?
Red blood cells are formed in the red bone marrow of bones. Stem cells in the red bone marrow called hemocytoblasts give rise to all of the formed elements in blood. If a hemocytoblast commits to becoming a cell called a proerythroblast, it will develop into a new red blood cell.
