Vascular tissue is involved in transporting water and nutrients throughout the plant body. Ground tissue is involved in photosynthesis and storage of food. An organ is a part of an organism, which performs a set of unique functions in the body. An organ is an incorporation of several types of tissue. There are five main organs in the animal body, which performs vital functions for the survival of an animal. They are brain, heart, lungs, liver, and kidney.
The brain is a component of the central nervous system of an animal, which coordinate body functions depending on the internal and external stimuli. Heart is the pump of the circulatory system of an animal, which transports both oxygen and nutrients to the cells in the body. Lungs serve as an interface that allows the exchange of respiratory gases between the blood and external environment. Within the lungs, the blood is saturated with oxygen while carbon dioxide is removed from the blood.
Liver serves as the main storage organ in the animal body. It stores glucose as glycogen. Kidney is the main excretory organ in the body, allowing the removal of metabolic wastes and the excess fluid from the circulation.
Organs in the animal body are organized into organ systems. The primary organs in plants are stem, root, and leaves. Flowers, seeds, and spores are considered as reproductive organs in plants. The structures in a flower are shown in figure 2. Tissue: Tissue is any of the distinct types of material of which animals or plants are made, consisting of specialized cells and their products.
Organ: An organ is a part of an organism, typically self-contained and has a specific vital function in the body. Tissue: A tissue is composed of similar types of cells.
In human anatomy, the variety of organs and organ system studied are:. Endocrine system — This system deals with hormones produced by endocrine glands like pituitary gland, hypothalamus, pineal gland, parathyroid, thyroid and adrenal gland.
Cardiovascular system — This system deals with the pumping of blood from the body, lungs with heart. Excretory system — Bladder, urethra, kidneys, and urethra are the parts involved in the excretory system.
Respiratory system — Pharynx, larynx, bronchi, lungs, diaphragm, trachea are the parts of used in breathing. Reproductive system — Testes, vas defrens, vulva, vagina, seminal vesicles, prostate, penis, ovaries, fallopian tubes, uterus are the parts of the reproductive system. Nervous system — Brain, spinal cord, and nerves are used to transfers and process information in the body.
Lymphatic system — It connects tissue and bloodstream and thus supports the immune system and provide protection against the disease. Digestive system — This system helps in digestion and includes parts like pancreas, gallbladder, colon, rectum, stomach, esophagus, salivary glands and anus are involved.
Skeletal system — It supports and provide shape to the body; it includes parts like tendons, ligaments, bone, and cartilage. In the above content, we studied the tissue and organs, as well their precise function. We also came to know the critical point on which these two differentiate. Even the cells, tissue and organs are specialized to play different roles. Your email address will not be published. Save my name, email, and website in this browser for the next time I comment. Key Differences Between Tissues and Organs Following are the few though important points to discriminate between tissue and organs: Tissues are the assembly between cells and organs and are evenly distributed structures in the body.
They are assigned to perform the fixed task. Tissues and organs are found in plants and animals, made up of similar cells which function in a precise manner. Organs are the hollow structure comprise of tissues and organized to work precisely for the body in animals as well as in plants.
The tissue is made up of the same type of cells while organs are the outcome of the same type of tissues. Tissue play limited though important role in the body and the prior one is to make organs.
While breathing, digestion, excretion of body waste, blood circulation are the different function performed by the different organs present in the body. Tissues can be repaired by regeneration and fibrosis but as tissues make organs, so repair in tissue, will result in repair of the organ. Nerve tissue, muscles tissue, connective tissue, epithelial tissue are the examples of the tissues, while stomach, lungs, heart, intestine, bladder, brain, kidney, etc.

Altered blood glucose levels can affect many organ systems. For example, the immune system may not heal as well, the urinary system may experience kidney damage, and the cardiovascular system can experience vascular damage, even to the point of causing blindness.
In the body, everything is interconnected. Beyond the body, populations and environment can impact physiology and health. Some diseases and disorders are common to certain populations, most likely because of genetic connections. Also, environmental conditions can impact health. Particulates in the air can impact respiratory function.
We are also affected by foods, exercise, sun exposure and other environmental conditions. Privacy Policy. Skip to main content. Module 5: The Tissue Level of Organization. Search for:. Muscle tissue in turn divided into skeletal, smooth and cardiac is contractile.
It allows locomotion of the body. It also allows necessary contractions of various organs such as the heart and of respiratory and digestive systems. It conducts signals between the nervous system and various organs. Connective tissue holds the body together. It is found in most organs, anchoring them to the skeleton and other organs.
