What is the difference between organs and tissues

Skip to main content. Organization at the Tissue Level. Search for:. Introduction to Tissues. Tissues in Levels of Organization The human body is organized at several levels of scale that can each be examined. Learning Objectives Characterize where tissues fall in levels of organization.

Key Takeaways Key Points The human body has many levels of structural organization: atoms, cells, tissues, organs, and organ system. 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. Organ: An organ is composed of several types of tissues. Tissue: Tissue is involved in performing a single function in the body. Organ: An organ is capable of performing several functions in the body. Tissue: Tissues are evenly distributed structures. Tissue: Tissue is the major structural component of an organ. Organ: Organs are the structural components of the organ system. Tissue: Epithelial tissue, connective tissue, muscular tissue, nerve tissue, and ground tissue are the examples of tissues.

Organ: Heart, stomach, intestine, lungs, and kidney are the examples of organs. Tissue: Tissues can be repaired by regeneration and fibrosis. Organ: The repair in tissues causes the repair in organs. It responds to stimulation and supports the movement.

The organ is the group of tissues present in a living organism and is assigned to perform the specific task. The stomach, the heart, the kidneys, the skin, and the liver are composed of tissue and together forms an organ system. Various organs perform the various function like pumping of the heart, breathing, reproduction, excretion, protection skin , etc.

All types of organs are made up of four types tissue. 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.

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. Types of connective tissue include fibrous tissue, fatty tissue, loose tissue and cartilage.

Connective tissue also includes bone, blood and lymph. Skin tissue helps to maintain homeostasis. It helps monitor and control temperature, and resists abrasion, foreign bodies and damaging chemicals. Internally, epithelial tissue lines most internal cavities, secreting or absorbing nutrients.
