Five Tissues Type Found Within Our Body

Welcome back everyone. Today I am going to talk about the tissue types found within our body before we continue to discuss the blood supply in our heart. There are 5 different type of tissues can be found within our body. They are organized as follows,

1. Connective and Supportive Tissue
These includes bones and fibrous tissues that connects and support two things together like cartilage and interosseus membrane between fibula and tibia. They support our body, aid in body movements and prevent our body from damaging itself from our daily activities.

Facts: Osteoporosis results because supportive tissues in our body is weakened or damaged. Bone, in this case, is where our body stores calcium to make hydroxyapitite, is weakened because of hormonal imbalanced or we are not ingesting enough calcium in our diet. Many implication may result from osteoporosis including bone fractures. On the other hand, arthritis is the inflammation of the joint due to the damages done on the articular cartilage between the bones. Since Articular cartilage is responsible to lubricate between the two bones along with synovial fluids found within the joint capsule. The loss of articular cartilage therefore induces inflammation within the joint and cause unbearable pain to that individual.

2. Hematolymphoid Tissue
This is the blood and lymph tissues that we always encounter in our daily lives. Their function is to transport stuff (nutrients and waste) into and out of our body. It also contains most of our immune responses within our body. This is where all the white blood cells, along with other regulatory proteins hang out and do most of their work.

Facts: Sickle cell anemia is a condition in which that our blood changes its shape and its affinity for oxygen. The lack of oxygen is a dangerous condition because it suffocates our organs and decreases the amount of oxidative phosphorylation happening in our cell, therefore our cells are unable to produce ATP and provide enough energy to drive chemical reactions in our body.

3. Muscle Tissue
Without a lot of scientific knowledge, we probably already know a lot about our muscle. There are three types of muscle tissues: cardiac tissue (the one we are most interested in), skeletal tissue and smooth muscle tissues.

Each tissue types are important for many functions and therefore are all essential for proper functioning of our body. First skeletal muscles are important for movements and generating heat to keep us warm. Cardiac muscle is important for regulating our heart beat and keeping a regular rhythm of our heart. Smooth mucle, on the other hand, is important for regulating vessel sizes and our digestive system.

Fact: atrial fibrillation results because our cardiac muscle cells are not regulated properly, therefore our atriums are not able to produce proper beating rhythm to push more blood into the ventricles of the heart. On the other hand, if our ventricle is not beating properly, in a condition called ventricular fibrillation, or V-fib, our entire heart does not beat properly, and the individual may result in death.

4. Nervous Tissue
The nervous tissues allows our organ to communicate with the brain and other structures of our body. It also allows outside stimulation to be transmitted into our body such as sound waves, light and sensational information. There are many types of nervous tissue found within our body.  It also the building units of our central nervous system, which consists of the brain and the spinal cord. There are several types of nervous tissues are particularly important: Multipolar neurons (Motor neuron) and pseudounipolar neurons (Sensory neuron).

Facts: Damage in the nervous tissue results in paralysis. The tibial nerve, located at the lower limb, is responsible for innervating the posterior compartment of our thigh and leg. If damaged, half of our lower limb will be paralyzed. Therefore severe injuries of nerves may cause paralysis of muscles as well as basic functioning of our body.

5. Epithelial Tissue
These are the covering for our body. Epithelial tissues protect our body from foreign invaders by providing a very hostile environment for bacteria and viruses. The different types of the epithelial tissues are summarized as follows:

Each of these tissues can be found at various parts of our body. Within our heart, we can also find each of these tissues types within the different compartments of our heart. Later on, I will covert the tissue types of our heart, including the three different layers of our heart surface and the inner compartments including valves and other anatomical structures found inside.

This is it for this week. Thanks for reading. If you have any questions, feel free to comment and I will try to respond asap. Have a good holiday!
